Description

  In the present invention, the toilet bowl surface is washed with a sufficient amount of washing water, and the toilet bowl that can be collected separately from the urine is connected to a conventional urinal, and is also connected to a urine septic tank and a urine processing device. Useful toilets that contribute to improving the quality of treated water by expanding the applicable range to save a large amount of water in the urine septic tank and urine treatment device and changing the treatment method of the urine septic tank by injecting a small amount of washing water Relates to providing a system.

As disclosed in Patent Documents 1 to 3, the present inventor has developed and proposed a simple flush toilet that separates manure and washing water, collects the manure in a toilet, and separates and collects washing water.
The design philosophy is to wash and collect the toilet bowl with sufficient washing water and drop the urine in the toilet bowl.
The ceramic flush toilet used in the past has a deodorization trap in the water channel leading from the toilet bowl surface and is connected to the pipe as it is. I could not do it.
The simple flush toilet does not use a large amount of wash water to store urine and wash water in the toilet tank, but uses 200 to 300 cc of a little water that transports filth to the toilet tank and cleans the toilet bowl surface. Is stored in a shield just under the bowl surface, and has a structure that prevents water sealing with a small amount of water.
Therefore, unlike a flush toilet, if this shield is used, it becomes the only toilet that can separate urine and flush water.

Another problem with the simple flush toilet was that the washing capacity was inferior compared to flush toilets because only a small amount of water could flow when considering the limit of the toilet tank capacity. Although it is possible to rely on the efforts of housewives in ordinary households, there were problems in temporary toilets for unspecified number of users.
In order to solve this problem, the present inventor considers dropping the urine into the toilet bowl, separating only the wash water from which the toilet bowl surface has been washed, and washing the bowl surface sufficiently with a large amount of water in the same manner as the flush toilet. It was. Moreover, since the water is not urine water, it can be permeated into the soil or sterilized and discharged, and after simple filtration and sterilization, it can be recycled as washing water. This is disclosed in FIG.
In areas where septic tanks and sewage systems are not widespread, pumping toilets and simple flush toilets are still used, and if the lack of cleaning power of simple flush toilets is resolved, the feeling of use will be the same as flush toilets. .

When the present inventor started the wash water separation toilet, it was considered to separate the wash water and treat it with soil, or to discharge it below the discharge standard value of the single septic tank at that time, but now resource saving and energy saving Is the largest element. Therefore, it is important from the standpoint of environmental conservation to completely separate manure and recycle it as washing water.
This is not only in Japan, but if developing countries with little water use the current flush toilet, for example, even 5 liters of water will be discharged once, not only the facility costs for the treatment plant but also the fear of water resource depletion will occur. . Recycling and reusing wash water to wash toilets comfortably, where a small amount of land can be used, combined with soil treatment of high-concentration sewage, etc. It can make a great contribution to people in developing countries.

The problem with each of the above-described inventions is that when washing water is poured into the toilet, manure is mixed into the washing water, and the reused or discharged washing water is contaminated. By applying the method proposed for the solid-liquid separation and flush water circulation toilet in Patent Document 5, the Japanese style toilet is connected to the footboard, and in the Western style toilet, the power switch is interlocked with the toilet seat, and it is energized only when the footboard or the toilet seat is lowered, After that, the toilet was washed by pressing the switch, but when I got used to the western style mainly used at home, the switch was pushed up and the urine was mixed into the washing water.
Further, in the case of a method of energizing and washing when leaving the tread board and toilet seat, in the case of boys' urine, it is difficult for the urine to be mixed into the washing water when the switch is pressed during the stool.
The second problem is that in the type of toilet in which large and small urinals are dropped together in the toilet bowl, the urine of boys' urine was easily mixed with the wash water because of the flush water intake on the upper side of the toilet bowl. Patent Document 4 proposes that the shield is pivotable during stool, the urine is sent to the toilet, the shield is fixed only during washing, and a water channel is provided at the rear of the shield to take in the washing water. However, there are problems such as paper being easily jammed and overflowing when a large amount of washing water flows.

  In order to solve these problems, in Patent Document 6, a toilet user is sensed by an infrared sensor or the like so as not to perform artificial washing, and in Reference Document 7, an upper portion of the toilet bowl just below the toilet bowl surface is used. The wash water was successfully separated without clogging with papers, etc., by taking the wash water with a slight gap in the whole defecation tube.

On the other hand, demands for water saving and CO2 reduction are also directed to toilets. Especially in public toilets, by reducing the amount of water in the flush toilet currently in use to one-tenth or less, the water charge is reduced at the same time as saving water, and the reduction in the amount of water discharged contributes to the reduction of the load at the treatment facility. The degree of contribution to society is large, such as CO2 reduction.
In order to save water in the public toilets and to improve single septic tanks, wash water separation toilets are indispensable. In addition, the present inventor has proposed and implemented a soil treatment apparatus for sewage for a long time. It is also effective to combine it with a manure septic tank as a high-concentration sewage treatment method.
The biggest problem is how to adapt a washing water separation toilet without filth transfer capability to a septic tank with a small piping gradient and a long piping distance.

Patent No. 3448189

  First of all, the water used in the conventional flush toilet is recycled by not using the toilet flushing water to drop down from the stool, but also by circulating the wash water from the flush toilet that separates the bowl bowl surface with the same amount of water as the conventional flush toilet. A super-water-saving toilet system that allows only one-tenth of the water to enter the septic tank, and secondly, a toilet system that transports stool and paper dropped from the wash water separation toilet with no conveying power to the pipeline to the septic tank and processing equipment. Thirdly, a toilet system in which the means of transportation is divided according to the number and use of toilet bowls, and fourthly, to improve the quality of the treated water discharged from the septic tank and reduce the amount of nitrogen that flows in to reduce the processing burden of the septic tank. In addition to reducing the amount of water entering the septic tank, fifthly, the toilet system to be reduced will be purified to a toilet flushing water by purifying the septic tank drainage water, whose drainage amount has decreased significantly, using soil in a small area Or use as a fertilizer, or soil treatment again with the gray water, it is to provide a toilet system or to discharge.

  In order to achieve the above-mentioned object, the present invention drops manure, paper, and a small amount of washing water from the toilet defecation opening, and the water for washing the toilet bowl face is separated by a separating device provided on the lower surface of the bowl face. The stool outlet of the washing water separation toilet that is not dropped is connected to the urine septic tank or the urine carrier pipe connected to the sewage processing apparatus, and part of the effluent water of the sewage septic tank or sewage processing apparatus is pressurized and supplied to separate the washing water. It is sent to the upstream side of the manure transport pipe connected to the toilet defecation port of the underfloor transport pipe connected to the toilet bowl, and the manure and paper are circulated to the manure septic tank or the manure processing apparatus.

Moreover, the microcomputer electric operation of the toilet cleaning of the flush water separation circulation toilet which uses the washing water to circulate the operation of the pump, which is a means for pressure-feeding a part of the effluent of the sewage septic tank or the sewage treatment device It has the function of turning on and off the power of the pump that supplies and supplies a part of the effluent water to the urine carrier pipe connected to the urine septic tank or urine processing device at the same time that the toilet outlet is closed and the toilet flushing water is flowing. It is characterized by that.
Also, the pump, which is the pressurized water supply means, is operated at regular time intervals with a timer or the like, and the water supply path is connected to the pipes upstream of the toilet outlets of a plurality of toilets to circulate the discharged water. It is characterized by that.

  In a system that uses the effluent of the sewage septic tank or sewage treatment device as a circulating transport means, the one equipped with a men's urinal flows the men's urine and washing water other than the circulation water supply circuit using the septic tank effluent, and For urinals, only stool, paper, and a small amount of toilet flushing water are sent to the circulation channel using septic tank effluent, and urine and flushing water are separated using a stool separation toilet that separates urine and toilet flushing water. The pressurized water supply circulation of the septic tank effluent discharged from other than the water supply channel using water is performed when a toilet is used or intermittently at regular intervals. Moreover, in a toilet system that uses the discharged water from the sewage septic tank or the sewage treatment device as a circulating transport means, the urine that flows into the septic tank and the toilet flushing water are guided to the soil treatment tank, and a part of the water after the soil treatment is toilet bowl. It is used as cleaning replenishing water, and the rest is discharged or used as liquid manure.

The urine single septic tank that has been used for a long time had to use a flush toilet with a ceramic trap for its toilet. This is because there was no flush toilet except for the structure of the flush toilet except that the urine and the wash water were mixed in the toilet bowl as the source.
In order to make the stool flow comfortably, it is better to have a lot of water, and it was also an era when it seemed to be a problem of water resources. Has been designed.
Also, in the septic tank, diluting the source of concentrated manure was also a part of the treatment. First, to drop the manure with a DOB value of 13,000 ppm per day to 260 ppm, the daily amount of toilet wash water was set at 50 liters. Was the starting point of the treatment. (Structural standards for urine septic tanks, same commentary-1976 Japan Architecture Center)
Therefore, highly diluted urine water was also contained in the digester where anaerobic microorganisms, which are said to have an organic concentration of 1%, are optimal. In this system, it is stored in the digester at a dilution rate of 5 times instead of 50 times.

  As mentioned above, the present inventor has made efforts to invent a toilet bowl that drops a small amount of water into the toilet bowl and that can be washed comfortably. However, only a small amount of water is dropped from the toilet bowl into the toilet bowl. It was limited to the amount of water transporting the distance, and putting more water into the toilet tank would hinder pumping. The toilet was devised and the wash water was separated from the source, so there was little water to flow with the stool, and the distance to the existing septic tank was long, so it was not possible to transport stool or paper. If filth can be transported to the septic tank regardless of the washing water each time, a purification system different from the septic tank starting from the current dilution degree can be considered.

Many former single septic tanks are provided with an anaerobic treatment portion as a pre-disassembly means for treatment.
However, there was a standard that the volume of the anaerobic treatment portion was at least 1500 liters in a septic tank of 5 people or less. Assuming that the normal 50l / day wash water is used and a family of five people fully use, it becomes 250l plus urine per day (1.5l / day), and there are only 5-6 days of residence. Moreover, it is highly diluted water that is not suitable for anaerobic treatment. Such a single urine septic tank is still in use and continues to discharge sewage without any means for improvement.
On the other hand, the wash water separation toilet proposed by the present inventor has a very small amount entering the septic tank while tasting the same feeling of use as a conventional flush toilet that flows a large amount of water. Even if 300 to 400 cc of toilet bowl wash water is dropped into the septic tank each time for 200 cc of urine, the amount of filth entering the septic tank is 5 liters per day per person (actually, the amount of washing water for men's urine is about 100 cc). Even if a family of five fully uses it, it becomes 25 l, which is exactly one-tenth the amount of a flush toilet.
Therefore, the staying days are 50 to 60 days.
Since the transport water is circulated and used for septic tank effluent, there is no risk of an increase in quantity even though it may decrease due to evaporation. The septic tank starts with full initial water in the tank, but the stool and paper, which have a large amount of BOD, gradually settle in the lower layer of the tank and continue to decompose. Since the staying days are 50 to 60 days, the concentration gradually increases, and the organic matter concentration suitable for anaerobic decomposition by microorganisms is about 1%, and the decomposition further proceeds. Anaerobic degradation is caused by facultative anaerobes such as Escherichia coli, Proteus, denitrifying bacteria, lipolytic bacteria, and fibrinolytic bacteria that liquefy large organic substances.
Organic substances are decomposed to produce organic acids such as acetic acid, butyric acid, propionic acid, formic acid, alcohols, and aldehyde compounds.
The degradation products seen from the substrate are as follows: Cellulose → Acetic acid, Butyric acid Carbohydrate → Acetic acid, Butyric acid, Acetone, Alcohol Protein → Amino acid, Fatty acid Fat → Fatty acid, Glycerin, Alcohol The liquefied product is methane The group of forming bacteria is used as a nutrient source and decomposes into gas such as methane and carbon dioxide. These gases scatter without accumulating in the water.
As described above, the anaerobic decomposition is advantageous when the organic matter concentration in the sewage is high. Decomposing dilute sewage takes days and the efficiency of decomposition is poor.
The activity of degrading bacteria differs depending on the treatment temperature. When heated to about 35 ° C in a treatment plant, etc., medium-temperature bacteria will be active. Decomposition will be completed in 15-30 days, but low-temperature bacteria that are active without heating in the domestic septic tank will be 16 ° C. Although it takes twice as much as mesophilic bacteria at about -20 ° C., significant degradation proceeds by staying for 50-60 days.
Since organic substances are reduced by such liquefaction and vaporization, the amount of sludge generated is much smaller than aerobic decomposition. “Functions and management of human waste treatment facilities” supervised by Shigeru Ono (Industrial Water Research Committee)
The amount of sludge by anaerobic decomposition is only 50-60 l per person per year.
A family of five can only collect about 300 liters per year, and it is sufficient to extract sludge once a year.

There is an example to be helpful for anaerobic decomposition of high-concentration manure with very small amount of water added.
The present inventor has developed a system for obtaining high-concentration urine water using a simple flush toilet and treating it with soil. The pretreatment part of patent document 8 is an anaerobic stool which decomposes | disassembles as it is, and makes use of the low temperature anaerobic bacteria which make 15 to 20 degreeC a living suitable temperature exist. There are many examples of continuous use without being pumped for many years. In winter, the resolution is reduced, but in the summer the decomposition ability is increased, and anaerobic bacteria work ceaselessly to reduce sludge. Among them, there is a system that is active throughout the year under natural temperature conditions near flat ground. An example of a soil treatment toilet system in Tanzawayama Nabewariyama, Kanagawa Prefecture, which was tested by the Ministry of the Environment as a mountain demonstration model experiment for one year from September 2004 to September 2005. is there.
Nabewariyama is 1,500 meters above sea level, and the winter snow cover period is about four months. The mountain climbs throughout the year, especially in spring and fall, and was used by 16,000 people during the verification model inspection period. This toilet is also connected to a mountain hut, and has more stools than ordinary public toilets. The temperature is 15 to 20 ° C over the course of one year under conditions of use close to home and near Tohoku. You can see how the low-temperature anaerobic bacteria working at the proper temperature work. The BOD value of the effluent from the anaerobic stool section was as follows.
The complete use of the toilet system started in November 2003, and the demonstration model inspection was from September 2004 to September 2005 after one year of use. Looking at the figure, it was ending at 220 ppm, September 27, 2004 660 ppm, October 25, 540 ppm, November 30, 430 ppm, December 20, 420 ppm, January 22, 2005, 440 ppm, July 11, 370 ppm, September 12, 220 ppm. It is interesting that the BOD value of the toilet effluent decreases according to the years of use. The toilet bowl is 5.5m ³ with 2.75m ³ in two units.
The toilet effluent temperature was 9 ° C on November 30th, 8 ° C on December 20th, 4 ° C on January 22nd, and the average temperature at the summit of November 7.2 ° C December 2.7 ° C January-2 .2 ° C. February-2.3 ° C. It can be seen that anaerobes continue to work without change in the toilet bowl. During this period, it has not been pumped. This anaerobic tank effluent is sent to the soil treatment, but as a pretreatment part, it is stably anaerobically decomposed, and sewage and a small amount of water are put into the septic tank filled with initial water and anaerobic decomposition In part, the aspect of decomposition is considered to be exactly the same in the present invention.

He continues to talk about improving the septic tank. A single septic tank is impossible to remove nitrogen and phosphorus because of its ability, and it is perfect to lower the BOD value, but it takes the energy of purification to oxidize the nitrogen in urine and replace it with nitrate nitrogen. ing. The nitrate nitrogen is also released without further decomposition. Therefore, if only the urine is removed from the toilet, which is the source of urine, the unnecessary burden on the septic tank can be reduced, and the chisso and phosphorus can be reduced from the discharged water, which was impossible until now. A big contribution can be made. Removal of nitrogen and nitrogen at the source is effective not only for single septic tanks, but also for combined septic tanks and other manure processing equipment, and can also be applied to new toilets. The amount of excretion of urine per person is 1000 to 1500 ml per day, the amount of urine is 100 to 150 g, and the ratio is 10: 1. The urine excreted per day contains 5 g of Chisso, 0.5 g of phosphorus and 2 g of potassium. Similarly, the stool contains 1 g of nitrogen, 0.4 g of phosphorus and 0.4 g of potassium. Phosphorus can only be reduced by about half, but with Chisso it can be reduced to 1/5. Although detailed means will be described in the embodiment, when the nitrogen flowing into the septic tank is reduced to 1/5, the supply of oxygen required for oxidation of the nitrogen is reduced, and that portion goes to the decomposition of other organic acids to improve the processing efficiency.
The diverted urine can be nitrated in aerobic soil, returned to the septic tank and denitrified using BOD in the tank as a carbon source, but if there is a little land, the urine is sterile. There is no restriction on fertilization, so it can be covered with soil and supplied to plants.

The septic tank that performs the pretreatment with the above-mentioned anaerobic microorganisms is specified to have a capacity of 1500 liters. The septic tank is treated by flowing on a plane that is easily oxidized after the primary treatment, or is purified by sending in air to oxidize. I was looking. For this type, it is thought that the purification will proceed further in the secondary treatment in terms of the concentration of sewage entering the anaerobic treatment of the pretreatment and the number of staying days, but it is a long-time back-up type septic tank installed in large quantities in the 1970s Is a problem. Depending on the model, there are many that have no pre-processing section and have been approved with a minimum line of 750 l for the entire capacity.
A method of using soil to improve this kind of thing was proposed. Of course, some land is required. However, the area is about 0.5 to 1m x 5m in a 5-person tank, and there are quite a few households that can be improved. The method recommended by the present inventor is not an osmotic type which is a concern for groundwater contamination, but the soil is enclosed with a synthetic resin film to treat the sewage, and the purified water collected at the bottom of the tank is used in various ways. . This is not possible with conventional septic tanks using flush toilets, with a wash water separation toilet bowl, while the toilet bowl is washed comfortably, the water entering the septic tank is 0.5 liters per person per day and 2.5 liters per family. This is because the amount of water is small. The minimum amount of soil per person is 50 cm wide, 70 cm deep, and 80 cm long. (0.3m per person ^3rd place)
It is most desirable to send a certain amount of water to a sunny place with an automatic pump and create a field and a flower bed on the surface. Plants can also use phosphoric acid adsorbed on soil.
The purified water collected in the lower part through the soil layer contains nitrate nitrogen and nitrite nitrogen because the phosphorus content is adsorbed to the soil, but a large fertilizer effect is not expected.
A vegetation spray instead of watering would be appropriate. Also used as toilet water for toilet flushing.
Even if it is discharged as it is, it is possible to guarantee almost the same water quality as that of the septic tank discharged water, which is highly treated. At this time, the old all-buck septic tank stops the buck and is used as an anaerobic tank.

A According to claim 1, only a small amount of flushing water in the toilet bowl is dropped from the defecation opening, and the septic tank discharge water is circulated through the septic tank or the treatment device. The men's stool only requires 400-500 cc of water to flow into the septic tank at a time, so it requires only 1/10 of the amount of water used by conventional flush toilets, and has a significant water-saving effect.
In addition, since the actual amount of manure and water flowing into the septic tank is reduced to 1/10, urine water having a concentration suitable for anaerobic treatment is accumulated in the anaerobic decomposition portion of the septic tank, and a sufficient residence time is secured. Depending on the type of the septic tank, some of the septic tanks can be reformed, such as separation buckle type and anaerobic plus aerobic treatment.
In addition, the effect of reforming can be expected even when the food in the parking area of the expressway is mixed with miscellaneous wastewater from restaurants.
B According to claims 2 and 3, it is possible to flow circulating water corresponding to the number and position of toilet bowls.
C Further, the quality of the discharged water can be improved by separating the urine according to claim 4 so as not to enter the septic tank. The removed urine and water should be used as liquid fertilizer as much as possible.
D Various combinations of soil treatment according to claim 5 are conceivable for the use of treated water, etc. First, the effect of assisting the non-release of the all-back type having only a volume of 750 l is great.
Of course, even if connected to a two-tank separation bucket, much better effluent water can be obtained.

The washing water separation toilet used in the present invention will be described.
That is what is disclosed in Model Document 7, but its features will be briefly described. The most important feature is that the water intake that separates the water that has washed the bowl surface is used as a water intake by creating a narrow gap around the outer periphery of the toilet bowl toilet. Since the circumference is about 3 times the diameter, a 5-8 mm gap can absorb a sufficient amount of water, work well in an invisible place, and the narrow gap does not suck in foreign matter. In addition to the above features, it also features a fully automatic cleaning operation using a human sensor to prevent urine from entering the cleaning water.

The structure of the flush water separation toilet which is the basis of the present invention will be described with reference to FIGS.
An annular water intake part 5 is formed between the toilet bowl part 3a and a counterfeit-like defecation pipe upper end part 4a on the outer periphery of the toilet bowl part 3a below the toilet bowl surface 2a. The drainage pipe 7 extends from the continuous annular water collecting part 6, and the shielding body 8 is provided in the defecation pipe 4 so as to be openable and closable below the stool passage opening 4 d below the upper end opening 4 a. A lock element 10 is provided that can stop the shield 8 in a closed position with respect to the toilet opening 4d. The distance d between the tubular member 4c and the toilet drop portion 3a determines the water intake amount and the water intake speed, and also determines the diameter of the drain pipe 7.

Briefly explaining the operation of the toilet, the lock function of the shield is operated by a microcomputer that senses the position of the user by means of a human sensor, and is locked when the user finishes the toilet completely, At the same time, a large amount of washing water is allowed to flow and is discharged out of the toilet bowl via the annular water intake 5 drain pipe 7.
The function of moving the circulation pump and opening and closing the water outlet solenoid valve to wash the toilet bowl surface at this time depends on the microcomputer. This also relates to the operation of interlocking the circulation pump of the underfloor circulation circuit with the septic tank discharge water described later.

Next, the usage state will be described. When the user does not enter the stool area, the electromagnet 10 and the water supply device are not operated, and the shield 8 is stopped so as to be able to open to the closed position. 4d is sealed with water so that the odor of the pipeline does not leak indoors.
When the infrared sensor detects that the user has entered the stool area, the water supply device operates to supply approximately 100 cc of wash water to the spout 11 and flow into the bowl surface 2a to wet the bowl surface 2a. And arrange so that urine does not stick easily.
The manure in the stool opens the toilet bowl 8a by its own weight and falls to the pipeline.
When the user who has finished the stool leaves the stool area and the infrared sensor can no longer detect the user, the water supply device operates to supply approximately 200 cc of wash water to the spout 11 and the bowl surface 2a. Then, the dropping paper or the like remaining on the bowl surface 2a is poured into the pipe.
Thereafter, immediately after the electromagnet 10 is turned on and the toilet passage 4d is locked in the closed position by the toilet bowl 8a, the water supply device is operated to supply about 5 l of washing water to the spout 11. Then, it flows on the bowl surface 2a. The washing water flows through the bowl surface 2a and then the inner surface of the guide pipe 3, and then flows into the annular water collecting part 6 from the annular water intake part 5 and flows to the outside through the water supply pipe 7 in FIG. Thus, after the washing water has flowed out, the energization of the electromagnet 10 is cut off and turned off, so that the shield 8 is unlocked and can be opened, and can be opened to the closed position and stopped. The portion 4d is sealed with water.

Next, a system that circulates the discharged water from the septic tank and supplements the conveying force of the flush water separation toilet will be described with reference to an example drawing of a certain household.
In FIG. 4, the conventional septic tank and the flush stool are kept in place, and the flush stool is replaced with the above-described flush water separation stool, and the stool and paper are transported by the discharged water from the septic tank. The septic tank used was divided into a pretreatment tank and a flash tank by a long-time flashing method (separated flash type), but it was 1200 liters in combination with the precipitation separation part and the flash part. As described above, high-concentration sewage was transported to the sedimentation separation part of the pretreatment part, and it seemed that fully modified effluent water was obtained by increasing the concentration suitable for anaerobic decomposition and the accompanying residence time. Since there is enough land in the garden, a soil treatment facility was also added, and the septic tank was not released. (It is legally a stool tank.) Since this part is the system of claim 5, it will be described later using the same figure.

Referring to FIGS. 4 and 5, reference numeral 21 denotes a conventional single septic tank. A deep tank 22 capable of storing about 50 l of discharged water is buried at the end of a conventional outlet, and a transport water pump 23 is inserted. A pipe line 24 connected to it is provided and connected to the upstream side of the part where the stool or paper falls from the toilet defecation port.
In FIG. 5, it is located upstream of the vertical pipe, but it may be upstream of the horizontal pulling portion. In the present embodiment, the transport water pump 23 is operated for the same time as the washing water supply time of the microcomputer operation for operating the washing water separation toilet. The transport water pump 23 is larger than the toilet flushing pump, and when the amount of water is too large, it is adjusted by squeezing the pipeline on the way. A small amount of water, urine, and paper that have fallen into the pipeline from the washing water separation toilet are pushed by the large amount of water and carried to the septic tank. Naturally, since this water is closed-pipe circulation, there is no legal problem even if it is sewage, and the amount actually added to the septic tank is less than 1/10 of that of the flush toilet.
In this embodiment, the water pump for transport is operated in conjunction with the microcomputer for the toilet bowl circulation cleaning operation. However, when the waste of a plurality of toilet bowls is circulated and conveyed, the timer operation described in claim 3 may be good. . In the case of public toilets, etc., power can be saved by adjusting the number of times of operation during the night or an assumed non-use time.

  The washing water separated by the washing water separating toilet 25 flows into the toilet flushing water purification tank 27 through the pipe line 29. Since the degree of contamination of the washing water is low, it is sufficient to provide a simple filtering device and place a slowly dissolving chlorine tablet in a cylinder. This inventor is filtering using the soil coarse particle | grains with quick water flow. (It is not shown in the figure.) In addition, this circulating water is an amount of 100 cc standing and 500 cc sitting, and gradually decreases after flowing into the septic tank, so it is necessary to automatically supply tap water and rain water using a ball tap or the like. In this embodiment, soil purification treatment water is used. Also, in public toilets equipped with multiple toilets, this cleaning water purification tank is not made for each toilet, but all toilets' cleaning water is collected in one place, soil treated, and supplied to each toilet with a well pump. Water discharged from each toilet cleaning nozzle is operated by an automatic cleaning operation by a microcomputer on a solenoid valve attached to each toilet.

Next, there is a system for separating the urine described in claim 4 and treating it separately so as not to enter the septic tank. There are various methods for separating urine, and some of them have already been implemented, but none of them has been considered for treatment of urine obtained by separation with the goal of water saving and anhydrous.
Men's urinals have a type that does not use new tap water by separating wash water from urine and circulatingly washing inside the urinal. If it becomes slightly dirty due to circulation, it will be discharged into the septic tank and sewer, but it has a great water-saving effect. Recently, it is also called an anhydrous urinal, a urinal that has a specific gravity smaller than that of water at the outlet of the urinal bowl surface, creates a water seal with a liquid that does not dissolve in water, blocks odors from below, and does not use water at all. Is also available in Japan.
In the toilet bowl, toilets that separate large and small urine are made mainly in Scandinavian Sweden, and it seems to be quite popular.
This toilet is mainly for household use. The stool is used as compost and the urine is used as liquid fertilizer. For ecological purposes, the WHO picks it up and promotes it to developing countries.

Although the object can be achieved by using any of the toilets as described above, the present inventor has disclosed an invention for separating the toilet bowl, urine and washing water in Patent Document 8, and this time based on this invention. Next, the urine separation toilet according to the cleaning method disclosed in the actual application 7 will be used. 6 and 7 illustrate one embodiment of the toilet used in the present invention.
The structure of the toilet and the microcomputer operating function shown in FIGS. 1 to 3 are exactly the same, but a slit 41 having a width of 5 to 7 mm is vertically formed in the center of the toilet bowl surface 2a, and a horizontal slit 42 is also formed in a T shape. Is provided. On the back side of the slit, a urine water collecting portion 43 is formed by forming a hollow portion in the pottery, or watertight and in close contact with the back surface of the bowl with a plastic molded product. A urine drainage pipe 44 is provided in connection with the urine water collecting part 43, bypasses the stool drainage pipe 4, and is piped outside through the back of the urinal.

Next, the operation of this toilet will be described.
When the user enters the detection area of the toilet sensor, the microcomputer starts to operate in the same manner as in the toilet bowl described in claim 1. However, when the user urinates, the urine passes through the urinal slits 41 and 42 to increase its size. The part is collected in the urine collection part 43, discharged to the outside of the toilet, and does not enter the pipeline that is conveyed by the septic tank discharge water. When the stool is made at the same time, the stool falls through the toilet bowl to the pipeline transported by the septic tank discharge water as in the operation of the first aspect, and both the stool and paper are transported and flow into the single septic tank 21.
This urine separation type urinal is dedicated to urine and female urine, and it is necessary to have male urine sitting down or to install a separate urinal. The male standing urine operates the toilet bowl, enters the defecation line, and is sent to the septic tank.
Washing the toilet bowl surface is the same for both large and small stools. After flushing 500 cc of wash water and dropping the stool and paper into the defecation line, when the user goes out of the sensor's sensing range, the shield is fixed and the circulating wash water is fixed. Flows to clean the bowl surface.
At that time, a small amount of circulating washing water flows into the urine slit and is discharged outside while washing the pipeline.
Circulating cleaning water may be set with a microcomputer a little more often.

The present inventor has provided a urine separation circuit in the urine of Western and Japanese style urinals and a flow channel for washing water in Patent Document 8, and a switching valve provided at a branch portion of the separation circuit after the urine flows Has been proposed to allow the washing water to flow after switching to a washing channel, allowing a certain time difference to flow, and separating only the urine from the water.
However, in the toilet bowl of this embodiment, circulating washing water for washing the bowl surface commonly flows when washing urine, and a small amount of washing water flows to the urine discharge pipe through the urinal slit each time. Since it is about 100-200cc each time, it is discharged with urine as it is.
Since the urine of this method is mainly infiltrated into the soil as liquid fertilizer, it has a dilution rate convenient as a fertilizer of about 4 to 5 times, and is used as it is.

By the way, although it is a urinal used only for male urinals, in this example, an anhydrous urinal was not used, but a flush water urinal was used.
The mechanism of the same type as the toilet flushing water separator corresponding to claim 1 is attached to the lower discharge part of the urinal in a form in which a part of the size is reduced. A description will be given with reference to FIG. In this embodiment, a conventional stall type urinal is used as a toilet body, and a circulating water tank 52 is provided on the lower side of the toilet. In order to make the depth of the tank as shallow as possible, the defecation pipe 4 is made as thin as possible, and the opening height h at which the shield 8 opens when the urine falls is set to about 1 cm. 200-300cc urine and 100-150cc wash water will pass sufficiently.
The main body 51 uses a ready-made ceramic urinal and also uses the urinal water seal. There was a shield 8 below and it was sealed with water, but a ready-made product was used. The induction tube 3 was also made as thin as possible. A submersible pump 53 is installed on the rear bottom surface of the circulating water tank 52 and connected to a discharge nozzle 54 provided on the upper surface of the toilet bowl surface to circulate one toilet unit. When many urinals are connected, the submersible pump 53 is not used and the drain pipe 7 can be connected to the outside from the rear of the circulating water tank, and can be intensively filtered and circulated.
The operation of the flush water urinal will be explained. When the user stands in the sensing area of the sensor and urinates, the shield 8 is in a free state, so the urine flows into the septic tank communication passage. When the user leaves the sensing area, the shielding body remains free and 100 to 150 cc of washing water flows and joins the septic tank communication passage.
Next, the shield 10 is fixed by energizing the electromagnet 10 by the operation of the microcomputer. Immediately after washing water 2 to 3 l washes the toilet bowl surface, it is discharged to the drain pipe 7 through the annular water intake part and the annular water collecting part. The operation during this time is the same as that of the toilet of Claim 1, and as soon as a series of circulating cleaning operations are completed, the shield becomes free and waits for the next user. If the next user enters the sensing area before the washing water circulation operation is completed, the circulation washing is stopped to prevent urine from entering the washing water. The urine is allowed to enter the septic tank in this embodiment, but the urine and 150 cc of washing water are not put into the septic tank, but supplied to the soil as liquid fertilizer, or nitrated in the soil and then returned to the septic tank and taken out of the room. The law is the same as in the previous section.

Next, a method for using the increased urine water according to claim 5 will be described. The effluent from the septic tank is used as circulating transport water for transport, but even in a super water-saving toilet, the falling water of urine 100-150cc stool 500cc, the stool of 150g once and the urine of 200-300cc once increase naturally. An embodiment of a system in which the soil-treated purified water obtained by treating the portion with soil is used for toilet flushing water of this system and used for other purposes will be described.
The overall arrangement and structure will be described with reference to FIG. In the transport water storage tank 22, the discharged water from the single septic tank 21 is stored and sent to the filth transport pipe 26 via the transport water pipe 24 as stool transport water. The transport water may be about 10 liters per flight, and the tank water storage amount may be about 30 liters. Toilet bowl wash water, urine and stool decomposition water flowing into the toilet tub flow out of the septic tank and into the tub 22. An overflow port is provided on the opposite side of the transfer pump in the tank 22 and flows into the soil treatment water tank 33 through the overflow pipe 32. This flow is a natural flow, and the conduit 32 allows surplus water to flow into the tank 33 with a slight gradient. The tank 33 is buried a little deeply, and when about 30 to 40 l of sewage is collected, a pump is operated by a float switch to feed about 20 l of sewage into the soil treatment tank 36 at a time. The soil treatment tank is embedded in the soil with a structure as shown in FIG. The soil treatment tank is made of a synthetic resin film having a thickness of 2 to 3 mm and is welded and formed in a box shape so that it reaches the ground surface and does not leak into the ground. Although the width is about 1 m and the length is arbitrary, in this embodiment, the length is 10 m. The depth is about 1 m. A synthetic resin porous tube may be arranged in two or three layers on the bottom surface of the soil tank, or cobblestones having a diameter of less than 10 cm may be arranged to have a depth of about 15 cm. A fine plastic net is laid on the synthetic resin perforated pipe and cobblestone to prevent the soil from falling from above.

In this part, purified water purified by soil is collected. A plastic cylinder is erected so as to reach the storage portion, and a water absorption hole is formed in the lower part thereof. This is a purified water intake tank 40. A submersible pump is placed at the bottom of the tube, and purified water is pumped and used for any purpose. In this embodiment, it is used to make up for the shortage of toilet flushing water that is sent to the toilet flushing water purification tank 27 and flows into the purification tank little by little.
A similar plastic tube can be set up in any part of this soil treatment tank to collect and use purified water, or to adjust the amount of water increase by rainwater. In this embodiment, the same purified water intake tank 37 is provided at the control position in the length direction of the purified water intake tank 40 of the soil treatment tank, and when rainwater exceeds a predetermined water level, it is activated by a float switch and sprayed on the hedge plant. is there. The sewage permeation trench 35 is a bowl-shaped long plastics product, and a plastic porous tube is fixed in it, and the irregular gravel of about 5 to 10 mm is formed in the gap between the trench and the porous tube or on the upper portion of the porous tube. The body is sprayed. The sewage flowing from one end of the perforated pipe is uniformly permeated into the soil tank, and the perimeter of the perforated pipe is kept in an aerobic state, thereby preventing clogging of the perforated pipe. The trench should be as shallow as possible, and the soil above the gravel should be 5-6 cm.

Next, the movement of sewage in the soil tank and the function of soil purification will be described.
The sewage entering the trench penetrates into the shallow soil through the perforated pipe and gravel layer. Since the sewage is prevented from permeating by gravity under the trench, the sewage that has passed through the gravel layer enters the area of capillary water in the soil existing in the narrow gap between the soil particles and moves capillary. This region is aerobic under the influence of air in the soil gap. The water that enters the capillary water area in the soil does not immediately go downward, but slowly moves down to 1m in the distance. During this time, it is purified by the action of soil microorganisms. The nature of the purified water is converted to nitrate nitrogen through urea ammonia, so there is no ammonia odor and it can be used for washing toilet bowls. Phosphorus is adsorbed on the soil and does not flow out. The water purified by the soil is used as toilet flushing water, sent to the septic tank, and returned to the soil treatment tank again as surplus water, so that the concentration of nitrate nitrogen gradually increases. It is desirable to use it as a plant fertilizer by being pumped from the purified water intake tank 37 in a state diluted with rainwater.
Also, most of the households that have once set up a single septic tank are mostly where wastewater is discharged as it is.
For the improvement, if there is room in the land, it is possible to collect soil from kitchen wastewater, bathroom washroom wastewater and laundry wastewater. At that time, when the water discharged from the purified water intake tank 37 is combined with the drainage and the soil is treated again, the nitrated nitrogen can be removed using the BOD contained in the kitchen drainage.
