Description

The present invention relates to a method for treating miscellaneous wastewater and toilet wastewater, which recycles wastewater from baths, laundry, kitchens, washrooms, and other household wastewater generated in accommodation facilities, and toilet wastewater from toilets, to obtain water for daily use and toilet flushing water.

Tap water refers to drinkable water used in kitchens, bathrooms, washrooms, etc., while grey water refers to water that is relatively clean but not potable, such as the water used to flush toilets or to water gardens, and sewage refers to the so-called wastewater that remains after using tap water and grey water.

Treatment of drinking water, grey water, and sewage is essential in living spaces, but traditionally, in various facilities and homes, drinking water was taken in from the outside through the water supply system and used for cooking in the kitchen, flushing the toilet, washing, watering the garden, etc., and the sewage after use was sent to a water purification plant through the sewer system for purification treatment before being discharged into rivers, etc. In some areas, the treatment capacity of the water purification plant was insufficient, and sewage was sometimes discharged directly into rivers, etc.

In recent years, trailer houses have been widely used as hotels, campsites, restaurants and lodging facilities. However, when trailer houses are used as hotels or lodging facilities, wastewater treatment from toilets, baths, laundry, kitchens and washrooms becomes an issue.

The applicant has previously proposed and obtained a patent for the following circulating water supply and drainage system, which purifies and recycles wastewater from various facilities and homes, and reuses it, while also utilizing rainwater, etc., thereby reducing tap water consumption to almost zero.
Patent No. 4178440

This patent document 1 describes a circulatory water supply and drainage system that uses a water supply and drainage system that includes a water supply device that can store grey water, such as rainwater, in two storage tanks after filtering it and supply it separately from each of the storage tanks as needed, a first water purification device that purifies the grey water supplied from one of the storage tanks by complex fermentation to obtain drinkable clean water, and a second water purification device that purifies the grey water from the other storage tank and the clean water from the first water purification device by complex fermentation to obtain grey water. The grey water sent from the other storage tank is transported to a grey water usage location such as a toilet, and the sewage sent from this grey water usage location is sequentially purified by the second water purification device and transported to the other storage tank, while the grey water sent from one of the storage tanks is purified by the first water purification device to make it potable water and transported to a clean water usage location such as a kitchen, and This is a circulating water supply and drainage system that is configured so that sewage from a water usage location is sequentially supplied to a second water purification device for purification and then transferred to the other storage tank. The main body of the first water purification device and the second water purification device are provided with a microbial treatment tank in which predetermined microorganisms are cultivated and air is pumped in, and a mineral treatment tank made by laminating mineral catalysts of silica catalyst, carbon catalyst, and material catalyst. In the microbial treatment tank, water to be treated is first charged with an enzyme solution for inducing fermentation, which is made by extracting enzymes from a raw solution consisting of water, extracts extracted from leaves of pine, bamboo, plum, fig, peach, persimmon, etc., bean curd refuse, and molasses, and then the fixed nitrogen, physiologically active substances, and protein crystals produced by the biological treatment are eliminated in the mineral treatment tank.

As shown in FIG. 11, Patent Document 1 includes a first water purification device 9 and a second water purification device 10.

The first water purification device 9 and the second water purification device 10 both purify water by complex fermentation. The first water purification device 9 filters grey water such as rainwater and stores it in two storage tanks 6 and 7. The grey water supplied from one of the storage tanks 6 of the water supply device 8, which can supply water separately from each of the storage tanks 6 and 7 as needed, is purified by complex fermentation to obtain drinkable clean water.

The second water purification device 10 is for purifying the sewage after using the grey water from the other of the two storage tanks 6, 7 and the clean water from the first water purification device 9 through complex fermentation to obtain grey water.

The grey water sent from the other storage tank 7 is transported to a grey water usage location 11 such as a toilet, and sewage sent from this grey water usage location 11 is purified in sequence by a second water purification device 10 and transported to the other storage tank 7. On the other hand, the grey water sent from the one storage tank 6 is purified in a first water purification device 9 to become drinking water and transported to a clean water usage location 12 such as a kitchen, and the sewage discharged from this clean water usage location 12 is supplied in sequence to the second water purification device 10 for purification before being transported to the other storage tank 7.

The main body of the first water purification device 9 and the second water purification device 10 is provided with a microbial treatment tank 20, 42 in which predetermined microorganisms are cultivated and air is pumped in, and a mineral treatment tank 21, 47 in which mineral catalysts such as silica catalyst, carbon catalyst and material catalyst are layered. In the microbial treatment tanks 20, 42-46, water to be treated is first charged with an enzyme solution for inducing fermentation, which is made by extracting enzymes from a stock solution consisting of water, extracts from pine, bamboo, plum, fig, peach, persimmon, etc., bean curd refuse and molasses. After the water is biologically treated by the microorganisms in the tank, the fixed nitrogen, biologically active substances and protein crystals produced by the biological treatment are eliminated in the mineral treatment tanks 21, 47.

In the diagram, 1 is a water supply and drainage system installed in a facility such as a residence 2, and 3 is a greywater receiving tank that receives greywater, i.e. rainwater.

The water supply device 8 is made up of a first storage tank 4, a filtration tank 5, a second storage tank 6, and a third storage tank 7, all connected by water supply pipes so that the grey water can be transferred in sequence.

Circulation pipes 13 connect the second storage tank 6 and the first water purification device 9, the third storage tank 7 and a place where grey water is used such as a toilet 11, the filter member 9b of the first water purification device 9 (described later) and a place where clean water is used such as a kitchen 12, the place where clean water is used 12 and the flow rate adjustment tank 10c of the second water purification device 10, the place where grey water is used 11 and the flow rate adjustment tank 10b, and the second water purification device 10 and the third storage tank 7.

The first storage tank 4, the second storage tank 6, and the third storage tank 7 are each provided with pumps 4a, 6a, and 7a for pumping out grey water, and the first storage tank 4 is connected to a fire hydrant (not shown) that serves as a water discharge point via a pump 4b and a water supply pipe.

Inside the greywater receiving tank 3, a grass layer 14 made of grass planted on top of soil, a sand washing layer 15, and a silica layer 16 are layered, and a water conveying pipe 17 connects the roof gutter to the first storage tank 4.

The first water purification device 9 is composed of a tank-shaped main body 9a consisting of a microbial treatment tank 20, a mineral treatment tank 21, and a treated water storage tank 22, a filter member 9b configured to filter the treated water obtained in the main body 9a by passing it through catalytic bamboo charcoal, SWA material, and a microfilter (not shown) in that order, and an adjustment tank 9c for temporarily storing the treated water to be fed to the main body 9a and for adjusting the amount of water fed.

The second water purification device 10 consists of a tank-shaped device body 10a, a first flow rate adjustment tank 10b for adjusting the flow rate of sewage fed into the device body 10a so that it is effectively treated by the device body 10a, and a second flow rate adjustment tank 10c.

The inside of the device body 10a is divided by partition walls into a first microbial treatment tank 42, a second microbial treatment tank 43, a third microbial treatment tank 44, a fourth microbial treatment tank 45, a fifth microbial treatment tank 46, and a mineral treatment tank 47.

The circulating water supply and drainage system in Patent Document 1 aims to purify, circulate, and reuse wastewater from various facilities and homes, as well as to reduce tap water usage to almost zero by utilizing rainwater, etc.

Then, the sewage water after use of the clean water obtained in the first water purification device and the sewage sent from places where grey water is used, such as toilets, are purified in sequence in the second water purification device and transferred to the other storage tank for circulation.

The circulating water supply and drainage system in Patent Document 1 is a fixed installation system, and is not suitable for installation in a trailer house or the like and can be transported on a trailer.

When making something portable like this, it is required that the system as a whole be compact.

In addition, in Patent Document 1, the only part that is considered to be a circulation system is the treatment of sewage into grey water, and the use of clean water is not circulated. Instead, the clean water after use is transferred to a process for treating the grey water as sewage, which makes the entire facility complex and unsuitable for a compact system.

The present invention aims to solve the problems of the conventional methods and provide a method for treating domestic wastewater and toilet wastewater that can safely treat wastewater in simple lodging facilities without mixing the two treatment systems by using a compact system that can be transported on a trailer to convert domestic wastewater (grey water) into clean water and circulate it as recycled water, and circulate toilet wastewater (sewage) as grey water for toilet flushing.

In order to achieve the above object, the present invention as described in claim 1 is capable of being transported by being loaded onto a trailer,
The system is divided into two routes: the recycled water route, which receives grey water from drinking water used in kitchens, bathrooms, and washrooms and treats it as grey water, and the toilet flush water route, which receives sewage from toilets and treats it as grey water.
The recycled water route is made up of a large surface area, special mesh structure, a flow control and fermentation tank equipped with spherical contact materials that generate and settle a biological film on the surface and purify the water by decomposing organic matter in the wastewater through the action of microorganisms, a relay tank, a combined treatment septic tank, a synthesis tank for promoting composite fermentation equipped with biocatalyst cloth made of strips of nonwoven fabric soaked in composite fermentation malt, a sand-carbon catalyst tank equipped with a catalyst made of sand and carbon, and a treated water tank for storing treated water.
The toilet flush water route consists of a contact catalyst tank with spherical contact materials, a solid fermentation tank with basalt material catalyst material, a relay tank, a sand/carbon catalyst tank, and a treated water tank for storing treated water.
The treatment tank of the recycled water route is connected to the domestic water piping, which is the piping for circulating the water supply and using it for daily life.
The treatment tank of the toilet flushing route is connected to the toilet flushing water pipe, which is the pipe that circulates and uses the water for flushing the toilet.
The flow rate adjusting and fermenting tank and the contact catalyst tank include:
The seed for complex fermentation is water to which an extract extracted from leaves selected from pine, bamboo, plum, fig, chestnut, peach, and persimmon, which are used as a culture medium as natural materials, and molasses are added to form a culture bed, and aerobic bacteria, anaerobic bacteria, and aerated anaerobic bacteria are inoculated into the culture bed , and the supernatant liquid is complex fermentation malt, which is a base for complex fermentation in which aerobic bacteria and anaerobic bacteria coexist , and a complex fermentation culture liquid is added, which is made by adding brewing water, molasses for aerobic fermentation, and an anaerobic base consisting of chicken manure, dried bean curd refuse, and rice bran, and
In the solid fermentation tank, complex fermentation occurs when a complex fermentation culture liquid is introduced into the flow rate control/fermentation tank and the contact catalyst tank . Through complex fermentation, the liquid and solid matter are separated and a MLSS bacteria bed, which is a fixed matter in the liquid, is formed. The gist of this complex fermentation is that the MLSS bacteria bed is returned from the solid fermentation tank to the contact catalyst tank .

In this invention, clean water refers to drinkable water for daily use, such as in kitchens, bathrooms, and washrooms, while grey water refers to water that is not potable but is relatively clean, such as water used to flush toilets or to water gardens, and sewage refers to so-called wastewater remaining after using clean water or grey water. For the sake of treatment, water after using clean water is treated as grey water, and wastewater from toilets is treated as sewage.

In this application, "MLSS bed for complex fermentation" refers to a bed on which anaerobic fungi preferentially grow, which is produced by complex fermentation technology using a complex fermentation culture liquid, in which anaerobic fermentation and solid fermentation occur in a settling tank or the like, so that microorganisms in a complex fermentation state attach (seed) to the MLSS, anaerobic fungi take root (implant), and the anaerobic fungi further colonize (bed). This is a bed on which anaerobic fungi preferentially grow.

"Complex fermentation technology" is a technology that creates a complex fermentation state, and "complex fermentation" is a process in which molasses, bean curd refuse, and leaves selected from pine, bamboo, plum, fig, chestnut, peach, and persimmon are added to the brewing water to create a plant extract, which is first subjected to lactic acid fermentation, a facultative anaerobic fermentation by lactic acid bacteria, and then fermentation bacteria and yeast produce physiologically active substances such as amino acids, sugars, vitamins, and minerals to suppress aerobic Fusarium (oxidizing bacteria). Next, following the lactic acid bacteria, fermentation bacteria, and yeast, aerobic actinomycetes produce antibacterial substances to suppress viruses, pathogens, rickettsia, and Fusarium. Next, photosynthetic bacteria are added at a time lag from the actinomycetes, and the photosynthetic bacteria take in gases such as carbon dioxide and nitrogen gas and exchange them for energy replacement such as photosynthesis, resulting in an ecosystem in which aerobic bacteria and anaerobic bacteria can coexist and prosper through symbiosis with breathable anaerobic bacteria.

"Multi-fermented malt" (bio-based) is made by adding an extract from leaves selected from pine, bamboo, plum, fig, chestnut, peach, or persimmon, soybean curd refuse, and molasses to water, and then inoculating aerobic bacteria, anaerobic bacteria, and breathable anaerobic bacteria into the mixture, allowing the aerobic and anaerobic bacteria to coexist, flourish, and live symbiotically through the breathable anaerobic bacteria, resulting in the supernatant liquid.

"Complex fermented malt" is the seed that causes complex fermentation, and contains carbon polymer-bound crystals. Complex fermented malt is made by adding water to an extract of leaves selected from pine, bamboo, plum, fig, chestnut, peach, or persimmon, which is used as a natural culture medium, and by adding this and molasses to water, a culture bed is created, and aerobic bacteria, anaerobic bacteria, and gas-permeable anaerobic bacteria are planted here, and the supernatant liquid creates the foundation for complex fermentation in which aerobic bacteria and anaerobic bacteria coexist, prosper, and live symbiotically through the gas-permeable anaerobic bacteria.

By planting aerobic bacteria, anaerobic bacteria, and breathable anaerobic bacteria at different times, the aerobic and anaerobic bacteria can coexist through the breathable anaerobic bacteria, but the activity of all aerobic and anaerobic Fusarium is suppressed, and the superconductivity of the biocatalyst occurs, suppressing the antagonism between the microorganisms, allowing symbiosis to take place, and thus leading to coexistence and mutual prosperity.

Coexistence, mutual prosperity and symbiosis mean not being antagonistic (not killing each other), and when microorganisms (bacteria) become one-tenth of their size, they stop killing each other and multiply. Within that space, physiologically active substances such as enzymes, vitamins, minerals and amino acids are produced, which are antioxidants and form polymer-bound crystals of carbon. When these are returned to water, they revert to being microorganisms. This can be seen in their proteins.

In other words, as a result of aerobic bacteria and anaerobic bacteria coexisting, thriving and living together through the breathable anaerobic bacteria, the number of microorganisms (viable bacteria count) per cc increases to ¹⁰ - ¹⁰ , bacteria do not die out, and as a result, the number increases dramatically to 10 - ^10. When the number of microorganisms (viable bacteria count) per cc increases from ^{10 - 10} to ¹⁰ , the size of the bacteria becomes 1/10, the bacteria go into suspended animation, bacteria do not die out, and as a result, the number increases dramatically to ¹⁰ - ¹⁰ , the microorganisms become highly dense, and further, the microbial enzymes become highly concentrated in this aqueous solution.

By leaving the supernatant, the precipitated sediment (organic matter) can be removed, allowing time to move on to preparing the culture medium.

"Complex fermentation culture liquid" is a liquid that induces complex fermentation, and is made by adding brewing water, molasses for aerobic fermentation, and anaerobic base for anaerobic fermentation to complex fermentation malt.

The anaerobic basis here refers to chicken manure, dried bean lees, and rice bran. Chicken manure is dried before it oxidizes, deteriorates, or putrefies. Dried bean lees is soybean cake left over after squeezing soy milk during tofu production, and is dried while it is fresh and before it oxidizes, deteriorates, or putrefies. Rice bran is the bran that is produced during rice polishing.

According to the present invention described in claim 1, by introducing MLSS bacteria beds for complex fermentation into the flow rate adjustment and fermentation tank of the recycled water route and the contact catalyst tank of the toilet flush water route, the water is purified by the action of microorganisms through complex fermentation.

This water purification process occurs when fermentation begins, and organic matter breaks down at the molecular level through lactic acid fermentation.

In the recycled water route, water that has been purified in a flow control/fermentation tank is led through a relay tank to a combined treatment septic tank, where the combined fermentation continues, and then sent to the synthesis tank.

In the synthesis tank, the complex fermentation is further promoted, and a biocatalyst cloth soaked in the accumulated complex fermentation malt is placed. The photosynthetic bacteria and algae fungi that are present and expressed on the biocatalyst cloth absorb carbon dioxide and nitrogen gas through light, and exchange and replace energy through photosynthesis, producing living substances and protein crystals.

In this way, the biological treatment and photosynthetic treatment almost completely stop the oxidation, deterioration and putrefaction of the treated water, eliminate bacteria, and turn all harmful effects of microorganisms into beneficial effects. In other words, the biological treatment and photosynthetic treatment allow the various bacteria to coexist, prosper and live symbiotically, bringing out the beneficial effects of microorganisms and stopping oxidation, deterioration and putrefaction.

The water is then sent from the synthesis tank to the sand-carbon catalyst tank, where all remaining hydrogen radicals (H+) are adsorbed by the inorganic catalytic carbon (C) contained in the carbon catalyst. The treated water is then sent from the treatment tank, which stores the treated water, to the domestic water piping and used as drinking water.

In the toilet flushing route, a MLSS bed for complex fermentation is added to the contact catalyst tank, and the water is purified by the action of microorganisms through complex fermentation. The contact catalyst tank receives toilet wastewater, including feces and urine, from the toilet bowl. When the MLSS bed for complex fermentation is added, fermentation begins, and organic matter is broken down at the molecular bond level through lactic acid fermentation.

The contact catalyst tank consists of multiple tanks, and as the waste material is transferred to each of them, complex fermentation progresses, producing decomposing bacteria and enzymes that break down and destroy the sludge made from human waste into water, carbon, and gas.

Both the recycled water route and the toilet flush water route are of the circulation type, returning treated water, and water purified by complex fermentation has a base that is more receptive to complex fermentation, so as the number of circulations increases over time, complex fermentation is effectively induced.

The wastewater is transferred from the contact catalyst tank to a solid fermentation tank containing a material catalyst material, where the SS is removed, and then sent to the sand/carbon catalyst tank via a relay tank.

In the carbon catalyst of the sand-carbon catalyst tank, all remaining hydrogen radicals (H+) are adsorbed onto the inorganic catalytic carbon (C) contained in the carbon catalyst, and the treated water that has been converted from sewage to grey water is taken from the treatment water tank that stores the treated water and used as flushing water for flushing toilets.

The present invention described in claim 2 is characterized in that the flow rate adjustment and fermentation tank, which is a flat tank with a low height relative to its width and depth, the relay tank for the recycled water route, the relay tank for the toilet flush water route, and the contact catalyst tank are arranged side by side on the lower level, and the combined treatment septic tank, synthesis tank, treatment tank for the recycled water route, and treatment tank for the toilet flush water route, which are vertically long tanks, are arranged side by side on the upper level and stacked.

According to the present invention described in claim 2, the system is designed to be compact and stable so that it can be transported on a trailer. Placing flat tanks on the lower level stabilizes the flow caused by overflow between the tanks, and by arranging the long tanks, such as the combined treatment septic tank, synthesis tank, and treated water tank, on the upper level, the tanks on the lower level can be used as a stand for installation.

The present invention as set forth in claim 3 is characterized in that the interior of the combined treatment septic tank is divided by partition walls into a plurality of tanks, namely a tank with spherical contact material arranged therein, a tank with a PVC net laid out therein, and a delivery tank, and the PVC net laid out tanks are further divided into a front and a rear plurality of tanks, and the MLSS culture bed produced by complex fermentation in the rear PVC net is returned to the front PVC net laid out tank .

According to the present invention described in claim 3, the combined treatment septic tank is for continuing the combined fermentation, and in the spherical contact material tank, the spherical contact material acts as a carrier to increase and attach microorganisms, so that combined fermentation is effectively achieved, and in the PVC net tension tank, the MLSS bacteria bed for combined fermentation is fixed, and by returning the fixed MLSS bacteria bed for combined fermentation to the PVC net tension tank in front, it is possible to further ferment, synthesize, or grow, making it easier for combined fermentation to occur.

As described above, the method for treating domestic wastewater and toilet wastewater of the present invention uses a compact system that can be loaded onto a trailer and transported, converting domestic wastewater (grey water) into clean water and circulating it as recycled water, while circulating toilet wastewater (sewage) as grey water for toilet flushing, thereby safely treating the wastewater treatment problems in simple lodging facilities without the two treatment systems mixing together.

FIG. 1 is a plan view showing an example of a trailer house in which a mobile unit type miscellaneous water and toilet wastewater treatment recycling system used in the miscellaneous water and toilet wastewater treatment method of the present invention is installed. 1 is a photograph showing the treatment state of each tank about one week after the start of operation of the toilet flush water route of the mobile unit type miscellaneous water and toilet wastewater treatment recycling system used in the domestic wastewater and toilet wastewater treatment method of the present invention. FIG. 1 is an explanatory diagram showing a conventional example.

The following describes in detail the embodiments of the present invention with reference to the drawings. Figure 1 is an explanatory diagram showing one embodiment of a mobile unit type wastewater and toilet wastewater treatment recycling system used in the method for treating domestic wastewater and toilet wastewater of the present invention, in which 18 indicates a simple accommodation facility such as a trailer house.

An example is shown in Figure 10, where the accommodation facility 18 is equipped with a kitchen, bathroom, washroom, bedroom, dining room, living room, toilet 19, etc. The example shown has two trailer houses lined up side by side.

The miscellaneous wastewater and toilet wastewater treatment recycling system device A of the present invention is provided for every two accommodation facilities 18, and can be transported on a trailer as described below.

The present invention separates the system into a recycled water route B, which receives grey water from the use of drinking water, i.e., domestic wastewater 24 from the kitchen, bathroom, washroom, etc., and treats it as drinking water, and a toilet flush water route C, which receives sewage, i.e., toilet wastewater 25 from the toilet 19, and treats it as grey water, and these two routes do not intersect.

Recycled water route B consists of a flow rate adjustment and fermentation tank 27 equipped with spherical contact materials 26, a relay tank 28, a combined treatment purification tank 29, a synthesis tank 30 equipped with biocatalyst cloth 36, a sand/carbon catalyst tank 31, and a treated water tank 32 for storing treated water.

The toilet flush water route C consists of a contact catalyst tank 33 in which spherical contact materials 26 are arranged, a solid fermentation tank 34 in which material catalyst material 37 is installed, a relay tank 35, a sand/carbon catalyst tank 31, and a treated water tank 32 for storing treated water.

In this way, in the recycled water route B and the toilet flush water route C, the synthesis tank 30 equipped with the biocatalyst cloth 36 is only located in the recycled water route B, and the solid fermentation tank 34 equipped with the material catalyst material 37 is only located in the toilet flush water route C. The reason for this is that the recycled water route B processes greywater into drinking water, while the toilet flush water route C processes sewage into drinking water, and the recycled water route B uses the photosynthetic action of the synthesis tank 30, and because toilet wastewater contains a large amount of organic matter, this can be treated in the solid fermentation tank 34.

The flow rate adjustment and fermentation tank 27 and contact catalyst tank 33 are tanks into which MLSS bacterial beds for complex fermentation are added, and the spherical contact material 26 is a fluid carrier that serves to increase and attach microorganisms. By using the carrier, it is possible to make the tank volume compact while maintaining the tank functionality.

A biological film is formed and established on the surface, and the microorganisms work to break down the organic matter in the wastewater and purify the water, which creates turbulence in the movement of the wastewater and increases the contact effect. In addition, the particles do not become entangled, and because the porosity is high, clogging due to attached sludge is unlikely to occur, resulting in excellent treatment efficiency.

In addition, because it is made of PP (polypropylene), it is lightweight, making it easy to transport, fill, and replace, and it is strong and durable, so it is less likely to deform or break.

The flow rate control and fermentation tank 27 and the solid fermentation tank 34 are equipped with aeration blower equipment with a desk-type diffuser 38a, while the contact catalyst tank 33, combined treatment septic tank 29, and synthesis tank 30 are equipped with aeration blower equipment with a tube-type diffuser 38b.

The interior of the combined treatment septic tank 29 is divided by partition walls into a tank 29a for arranging the spherical contact materials 26, a tank 29b for laying the PVC net 41, and a discharge tank 29c.

The biocatalyst cloth 36 in the synthesis tank 30 is a strip of nonwoven fabric impregnated with composite fermentation malt and is suspended at a specified interval.

The sand-carbon catalyst tank 31 is a cylindrical tank that contains a carbon catalyst.

In the figure, three contact catalyst tanks 33 containing spherical contact materials 26 are provided, and a solid fermentation tank 34 containing basalt material catalyst material 37 is installed next to each of them. The wastewater is fed sequentially from the first contact catalyst tank 33 through the second contact catalyst tank 33 and the third contact catalyst tank 33 to the solid fermentation tank 34. The feeding method may be overflow.

The solid fermentation tank 34 is equipped with a relay tank 35 equipped with a relay pump 39.

The piping of this relay pump 39 is connected to the sand/carbon catalyst tank 31, from which the treated water is sent to the treated water tank 32, from where it is used by the automatic water supply pump 40 as flushing water for flushing the toilets 19.

Next, a configuration that allows transportation by being loaded onto a trailer will be described.
2 and 3 show an example of this, which is a 12-ft container type, with the lower section consisting of flat rectangular tanks that are low in height compared to their width and depth, and are arranged side by side with a flow rate adjustment and fermentation tank 27, relay tank 28, contact catalyst tank 33, and relay tank 35, all of which are approximately the same height, and are surrounded by a frame made of angle bars that serves as a stand 49, the whole of which fits the rectangular shape of the container. Note that in order to suppress shaking due to vibration, rubber plates 48 are laid underneath and these tanks are placed on top of this.

On the other hand, the upper level is lined up with the combined treatment septic tank 29, synthesis tank 30, sand/carbon catalyst tank 31, and treated water tank 32, which are vertically long tanks. In this way, the lower level and the upper level are stacked via the stand 49.

The combined treatment septic tank 29, synthesis tank 30, sand/carbon catalyst tank 31, and treated water tank 32 located on the upper level are all at different heights, but the sand/carbon catalyst tank 31 is placed on a stand 50 placed underneath it.

When used, in recycled water route B, purification is first carried out by complex fermentation in a flow control and fermentation tank, and the purified water is then led through a relay tank to a combined treatment purification tank, where complex fermentation continues for further purification.

The amount of MLSS culture bed added for the complex fermentation in the flow control and fermentation tank 27 is an amount that results in a concentration in the tank of 2000 ppm to 3000 ppm or more. The MLSS culture bed may be diluted with water before addition.

The principle of complex fermentation is as described above. As a result of aerobic bacteria and anaerobic bacteria coexisting, thriving and living together through the gas-permeable anaerobic bacteria, the number of microorganisms (viable bacteria count) per cc increases to ¹⁰ - ¹⁰ , bacteria do not die out, and as a result, the number of microorganisms increases dramatically to 10 - ^10. When the number of microorganisms (viable bacteria count) per cc increases from 10 ^{- 10} to ^{10 ,} the size of the bacteria becomes 1/10, the bacteria go into suspended animation, bacteria do not die out, and as a result, the number of microorganisms increases dramatically to ¹⁰ - ¹⁰ , the microorganisms become highly dense, and further, the microbial enzymes become highly concentrated in the aqueous solution.

Treatment of fermentation-based prioritized microorganisms with aerobic bacteria such as lactic acid bacteria and yeast fungi, treatment of fermentation and fermentation synthesis-based microorganisms with the aforementioned aerobic and anaerobic bacteria such as lactic acid bacteria and actinomycetes, and treatment of fermentation synthesis-based microorganisms mainly with anaerobic fungi suppresses oxidation, deterioration, and decay through antioxidant effects, produces physiologically active substances such as amino acids, sugars, vitamins, and minerals, suppresses E. coli, miscellaneous bacteria, and general bacteria, produces antibiotics such as Streptomyces penicillium, and sterilizes and inhibits the growth of viruses, pathogens, and rickettsia.

This complex fermentation continues in the combined treatment septic tank 29, and is promoted in the synthesis tank 30. In particular, in the synthesis tank 30, the photosynthetic bacteria and algae fungi present and expressed in the biocatalyst cloth 36 absorb carbon dioxide and nitrogen gas through light, and exchange and replace energy through photosynthesis, producing living substances and protein crystals.

In the sand-carbon catalyst tank 31, all hydrogen radicals (H+) remaining in the carbon catalyst are adsorbed onto carbon (C), an inorganic catalyst contained in the carbon catalyst.

The treated water is sent from the treatment tank where it is stored to the domestic water pipes and used as drinking water.

Table 1 below shows the results of water quality analysis.

In toilet flush water route C, complex fermentation is carried out in the contact catalyst tank 33 by adding an MLSS culture bed for complex fermentation.

The amount of MLSS culture bed added for the complex fermentation in the contact catalyst tank 33 is an amount that results in a concentration in the tank of 2000 ppm to 3000 ppm or more. The MLSS culture bed may be diluted with water before addition.

When fermentation begins in the contact catalyst tank 33, complete fermentation occurs and organic matter is broken down at the molecular bond level through lactic acid fermentation. Decomposing bacteria and enzymes are activated, and the sludge from human waste is broken down into water, carbon, and gas.

In the solid fermentation tank 34, anaerobic fermentation and solid fermentation occur, decomposing bacteria and enzymes are produced, and further decomposing bacteria and enzymes are produced, causing the sewage to break down and disappear into water, carbon, and gas.

The solid fermentation tank 34 has an SS removal layer using a material catalyst material 37, and by harvesting the combined fermentation MLSS culture bed and returning it to the contact catalyst tank 33 , which is the initial fermentation liquefaction tank, the combined fermentation MLSS culture bed can be further fermented, synthesized, or multiplied, making it easier for combined fermentation to occur in the contact catalyst tank 33, which is the fermentation liquefaction tank.

The water is sent from the solid fermentation tank 34 via the relay tank 35 to the sand-carbon catalyst tank 31, where all remaining hydrogen radicals (H+) are adsorbed by the inorganic catalytic carbon (C) contained in the carbon catalyst. The treated water is then sent from the treated water tank 32, which stores the treated water, to the automatic water supply pump 40, where it is used as flushing water for flushing toilets.

Figure 10 is a photograph showing the treatment status, showing the treatment status of each tank in toilet flushing water route C about one week after operation started, immediately after pumping.

From the left, the cylinders show the conditions inside the contact catalyst tank 33 (first), contact catalyst tank 33 (second), contact catalyst tank 33 (third), solid fermentation tank 34, sand-carbon catalyst tank 31, and treated water tank 32.

In the state shown in Figure 10, the sludge is not yet completely liquefied in the contact catalyst tank 33, but it is almost completely liquefied in the solid fermentation tank 34, and is almost completely purified in the final sand/carbon catalyst tank 31.
