Description

TECHNICAL FIELD The present invention relates to kitchen wastewater treatment equipment.

Kitchen wastewater discharged from a kitchen of a restaurant generally contains kitchen waste (garbage), oil and fat, and water. In order to prevent the garbage and grease contained in the kitchen wastewater from being discharged directly into the sewage system, a grease trap is provided in the kitchen to separate and collect the garbage and grease from the kitchen wastewater. Kitchen waste and oils and fats collected by a grease trap are generally prone to putrefaction and cause offensive odors. For this reason, it is preferable to dispose of the collected garbage and oils and fats promptly so as not to spread offensive odors.

Patent Literature 1 discloses a waste treatment system that treats kitchen waste and oils and fats collected from kitchen wastewater with anaerobic bacteria to generate methane gas and uses the generated methane for boilers and power generation.

Japanese Patent No. 5201689

In order to obtain the amount of methane gas that can be used in boilers and power generation using the waste treatment system disclosed in Patent Document 1, a large amount of kitchen waste and oils and fats are required. Therefore, such a waste disposal system is considered useful in large-scale facilities such as food processing plants and hotels. On the other hand, it is not realistic to use the waste treatment system disclosed in Patent Document 1 in the kitchens of small-scale restaurants that generate relatively small amounts of kitchen waste and oils and fats. Therefore, in the kitchens of small-scale restaurants, there is a demand for a treatment apparatus that is small in size and capable of treating odors generated from garbage collected from kitchen wastewater and fats and oils so as not to spread.

The present invention has been made in consideration of the above circumstances, and its object is to be able to dispose of kitchen waste and fats and oils contained in kitchen wastewater without diffusing offensive odors, and to facilitate miniaturization. To provide a kitchen wastewater treatment device with a simple configuration.

In order to solve the above problems, the present invention employs the following means.

(1) A kitchen wastewater treatment apparatus according to one aspect of the present invention is a kitchen wastewater treatment apparatus for treating kitchen wastewater containing kitchen waste, oil and fat, and water, and comprises a sink section and a sink section below the sink section. a disposed grease trap portion, a garbage volume reduction processing portion for reducing the volume of the garbage, and an exhaust portion for exhausting the gas in the garbage volume reduction processing portion to the outside, A drain port for discharging the kitchen wastewater is provided at the bottom, the kitchen waste volume reduction processing unit includes a treated residue outlet for discharging treated residue after volume reduction, and the grease trap portion and the treated residue outlet are connected.

According to the kitchen wastewater treatment apparatus of the aspect described above, since the grease trap section is arranged below the sink section, the size of the apparatus can be reduced. In addition, by forcibly exhausting the gas inside the grease trap to the outside by the exhaust section, it is possible to prevent the diffusion of offensive odors due to the garbage and oil collected in the grease trap. Furthermore, the sink portion and the grease trap portion are separable, and by separating the sink portion, it is possible to relatively easily take out the garbage and oil collected by the grease trap portion to the outside. Therefore, in the event that kitchen waste or oils and fats are decomposed in the grease trap portion and an offensive odor is generated, the offensive odor source of the garbage or oil can be quickly removed so that the offensive odor does not spread.

(2) In the kitchen wastewater treatment apparatus of (1), the grease trap section may further include a solid outlet for taking out solids to the outside.

BEST MODE FOR CARRYING OUT THE INVENTION A kitchen wastewater treatment apparatus according to one embodiment of the present invention will be described below with reference to the drawings.
The kitchen wastewater treatment apparatus of this embodiment is used, for example, for treating kitchen wastewater generated in restaurants. Kitchen wastewater generally contains kitchen waste (garbage), oils and fats, and water. The kitchen wastewater treatment apparatus of this embodiment has a function of collecting kitchen waste contained in kitchen wastewater and reducing the volume of the collected kitchen waste.

FIG. 1 is a plan view of a kitchen wastewater treatment apparatus according to one embodiment of the present invention. FIG. 2 is a sectional view taken along line II--II of FIG. 3 is a front view of the kitchen waste water treatment apparatus shown in FIG. 1. FIG. FIG. 4 is a plan view illustrating the flow of kitchen waste water in the grease trap, with the sink portion of the kitchen waste water treatment apparatus shown in FIG. 1 separated.

As shown in FIGS. 1 to 4, the kitchen wastewater treatment apparatus 10 of the present embodiment includes a sink portion 20, a grease trap portion 30 arranged below the sink portion 20, and a It has a garbage volume reduction processing unit 50, a connecting pipe 70 connecting the grease trap unit 30 and the garbage volume reduction processing unit 50, and an exhaust unit 80 connected to the garbage volume reduction processing unit. In the kitchen wastewater treatment apparatus 10 of this embodiment, the sink portion 20 and the grease trap portion 30 overlap each other in plan view. Therefore, the kitchen wastewater treatment apparatus 10 of this embodiment can be installed in a smaller planar space than when the sink portion 20 and the grease trap portion 30 do not overlap each other in plan view.

A kitchen waste water treatment device 10 has a top plate 11 and a back guard 12 on the top, and a decorative plate 13 on the side. A footrest 15 for supporting the kitchen wastewater treatment apparatus 10 is provided at the lower portion of the kitchen wastewater treatment apparatus 10 , and a reinforcing material 14 is installed on a part of the footrest 15 . Since the kitchen wastewater treatment apparatus 10 of this embodiment has the pedestal 15 at the bottom, wastewater and solid matter can be easily discharged and/or recovered from the U-shaped pipe 39 and the solid matter outlet 40, which will be described later.

The sink part 20 is a water tank for receiving kitchen waste water 1, and has a substantially rectangular opening. The sink part 20 has a drain port 21 for discharging the kitchen waste water 1 at the bottom, and the bottom surface of the sink part 20 has a gradient that gradually decreases toward the drain port 21 . Handles 22, 22 are attached to the upper end portions of the opposing inner wall surfaces of the sink portion 20 so as to be embedded therein. By pulling out and lifting the handle 22, the sink portion 20 and the grease trap portion 30 can be separated. The sink portion 20 also includes a drain plug 23 for closing the drain 21 . Further, an overflow hole (not shown) is provided in the upper side of the sink portion 20 . When the kitchen waste water 1 in the sink part 20 continues to increase while the drain port 21 is closed by the drain port plug 23, the kitchen waste water 1 flows into the grease trap part 30 through the overflow hole. Therefore, the kitchen waste water 1 does not overflow from the kitchen waste water treatment device 10. - 特許庁
In addition, it is preferable to provide a simple deodorant mechanism in the overflow hole. As the deodorant mechanism, for example, a self-weight closed type one may be used. The self-weight closed type deodorizing mechanism is a mechanism that uses a sealing member that normally closes the overflow hole by its own weight, and that detaches from the overflow hole to open the overflow hole when the water level of the kitchen drainage 1 increases. As a result, it is possible to prevent the odor that normally rises from the grease trap portion 30 and the oil/water separation trap 36, which will be described later, from leaking through the overflow hole.

The grease trap unit 30 separates the kitchen wastewater 1 into kitchen waste 2 (solid) and liquid 3, and collects the kitchen waste 2 in a kitchen waste collection area 31. and an oil-water separation region 34 for separating the oil and water 5 . The grease trap section 30 further includes a drain pipe 38 for taking out the water 5 separated in the oil-water separation area 34 and a solids outlet 40 for taking out fine solids that have passed through the basket 32 .
In FIG. 2, the grease trap portion 30 has a flat bottom surface. In addition, the bottom surface of the grease trap portion 30 may not be flat, and may have, for example, a slope that gradually decreases toward the oil-water separation trap 36 described later.

The garbage collection area 31 includes a basket 32 and a basket support portion 33 that detachably supports the basket 32 .
The basket 32 is a porous body having drainage holes, and separates and collects the kitchen waste 2 from the kitchen waste water 1 by allowing the liquid 3 in the kitchen waste water 1 to pass therethrough. A wire mesh, a punching metal plate, an expanded metal plate, or the like can be used as the material of the basket 32 . The basket 32 is preferably covered with a net (not shown) having a smaller hole diameter than the drain port of the basket 32 so that the garbage 2 can be collected together with the net.

The net covering the basket 32 is preferably made of a biodegradable resin material. Since the net made of a biodegradable resin material can be decomposed by microorganisms together with the garbage 2, the garbage 2 in the basket 32 can be thrown into the garbage volume reduction processing unit 50 together with the net. Examples of biodegradable resin materials include starch, cellulose, ligcellulose, nanocellulose fiber, polylactic acid, polyglycolic acid, polyaspartic acid, polycaprolactone, polybutylene succinate, polybutylene succinate adipate, and polybutylene adipate terephthalate. , polyethylene terephthalate succinate, and polyvinyl alcohol.

As the net, a foldable net can be used as shown in FIG. In FIG. 5, (a) is the folded state before use, (b) is the state in the middle of unfolding, and (c) is the unfolded state. A foldable net 90 has a net bag 91 having a rectangular opening 92 and grips 94 provided at a pair of edges of the opening 92 . (a) is in a state in which the pair of edge portions 93 not provided with the grip portion 94 are folded inward before use. When unfolding the foldable net 90, the edge 93 is opened by pulling the handle 94 outward as shown in (b). When the basket 32 is covered with the net with the rectangular openings 92, the edges 93 and the handle 94 are bent outward to bring the net into close contact with the basket 32, as shown in (c). Since such a folding net 90 is not bulky before use, the storage space can be reduced. Moreover, by using the foldable net 90, the residue can be transported well, and the maintainability can be improved. Furthermore, after the basket 32 is covered, the edge portion 93 is supported by the basket 32 to prevent excessive deformation, resulting in excellent shape stability.

The oil-water separation area 34 has a partition plate 35 and an oil-water separation trap 36 .
The partition plate 35 has a function of adjusting the outflow direction of the liquid 3 so that the liquid 3 that has passed through the basket 32 flows upward between the partition plate 35 and the basket support portion 33 . By causing the liquid 3 to flow upward, the oil 4 in the liquid 3 with a relatively low specific gravity moves upward quickly, and the water content 5 in the liquid 3 with a relatively high specific gravity moves downward. .

The oil-water separation trap 36 includes a tubular member 37 (baffle) and a drain pipe 38 arranged inside the tubular member 37 .
The tubular member 37 is a cylindrical member having an opening 37a at the bottom and a ventilation hole (not shown) at the top. Since it is difficult for the oils and fats 4 with a small specific gravity to move downward to the opening 37 a of the tubular member 37 , water 5 with a large specific gravity is predominantly taken into the opening 37 a of the tubular member 37 .

The drain pipe 38 has an opening 38a on the upper side and a U-shaped pipe 39 on the lower side. The water 5 taken into the cylindrical member 37 is sent to the drain pipe 38 through the opening 38a and taken out to the outside (sewage pipe) through the U-shaped pipe 39. As shown in FIG. By passing through the U-tube 39, it is possible to prevent foreign odors from entering the grease trap portion 30 from the outside.

The oil-water separation trap 36 is preferably arranged in the center of the oil-water separation area 34 . In this case, since the flow of the liquid 3 proceeds in all directions of the oil-water separation region 34, the entire oil-water separation region 34 can be effectively used, and the oil and fat components 4 and the water content 5 can be efficiently separated even with a small size. can be separated (see FIG. 4).

A solid matter outlet 40 is arranged at the bottom of the grease trap portion 30 . The solid matter outlet 40 is provided with a cock 40a, and by opening the cock 40a, the solid matter 6 deposited on the bottom can be appropriately taken out to the outside.

The garbage volume reduction processing unit 50 includes a garbage input port 51 provided at the top, a garbage processing tank 53 provided inside, and the processing residue 7 of the garbage 2 reduced in volume in the garbage processing tank 53 to the outside. It has a processing residue discharge port 59 for discharge and a control plate 60 . The garbage inlet 51 is provided with a lid 52 .
The garbage inlet 51 can be provided at the top and/or side of the garbage volume reduction processing unit 50 . In this embodiment, the case where the garbage inlet 51 is provided on the top will be described, but when the garbage inlet 51 is provided on the side, it is preferable to adjust the lid so that it opens at an angle of about 45 degrees. In this case, the work of throwing in the garbage collected by the basket 32 becomes relatively easy.

The garbage disposal tank 53 includes a perforated plate 54 provided at the bottom, a garbage disposal material 55 arranged on the perforated panel 54, an agitator 56 for agitating the garbage disposal material 55, and the agitator 56. and a supporting rotating shaft 57 . The garbage disposal material 55 is a carrier carrying microorganisms capable of decomposing the garbage 2 . As microorganisms, for example, aerobic bacteria can be used. The garbage disposal material 55 is sized so as not to pass through the holes 54 a of the perforated plate 54 . The stirrer 56 has a spatula 56a at its tip. A rotating shaft 57 is rotatably supported by a motor 58 .

When aerobic bacteria are used, a water supply device may be attached to supply water into the garbage treatment tank 53 in order to promote the activity of the aerobic bacteria. Moreover, in order to promote the activity of aerobic bacteria, an intake port for taking in air may be provided in the garbage disposal tank 53 . The intake port can be provided near the garbage inlet 51, for example.
The garbage disposal tank 53 is preferably removable. As a result, when the garbage disposal tank 53 breaks down, only the garbage disposal tank 53 can be replaced.

The processing residue discharge port 59 discharges fine processing residues 7 that have passed through the hole portions 54a of the perforated plate 54 of the garbage processing tank 53 to the outside. The processed residue discharge port 59 has a lower surface 59a inclined downward toward the outside, and the processed residue 7 moves on the lower surface 59a by its own weight and is discharged to the outside.
Further, in order to wash away the processed residue 7 in the processed residue discharge port 59, a water supply device may be provided above the inclined portion of the lower surface 59a to supply water into the garbage disposal tank 53. Furthermore, the shape of the lower surface 59a may be a shape (tapered shape) in which the width gradually tapers from above toward the connecting pipe 70 . As a result, the processing residue 7 in the processing residue discharge port 59 is more efficiently discharged to the outside.

The control board 60 manages the operation of the garbage volume reduction processing section 50 . The control plate 60 controls, for example, the motor 58 to adjust the stirring speed of the garbage disposal material 55 by the stirrer 56 . In addition, the amount of water supplied to the garbage disposal tank 53 or the treated residue discharge port 59 is adjusted by controlling the water supply device attached as necessary. The garbage volume reduction processing unit 50 may adjust the internal temperature using a heater (not shown). When the garbage 2 is volume-reduced using microorganisms, the internal temperature of the garbage volume-reduction processing unit 50 is preferably adjusted according to the activity of each microorganism. The temperature control of the heater may be performed by the control plate 60 described above.

The connecting pipe 70 connects the grease trap portion 30 and the processed residue discharge port 59 of the garbage volume reduction processing portion 50 . The connection pipe 70 has an end portion on the side of the grease trap portion 30 arranged at a position to receive the processing residue 7 in the basket 32 of the garbage collection area 31. 32 to make it retrievable.

The exhaust unit 80 is connected to the garbage volume reduction processing unit 50 and forcibly exhausts the gas inside the garbage volume reduction processing unit 50 to the outside. The gas in the grease trap section 30 is forcibly exhausted together with the gas in the garbage volume reduction processing section 50 through the connecting pipe 70 (see FIG. 2). The sink portion 20 and the grease trap portion 30 are separable, and since a gap is formed between the sink portion 20 and the grease trap portion 30, the inside of the grease trap portion 30 and the garbage volume reduction processing portion 50 can be separated. Even if the gas is forcibly evacuated, the internal pressure will not be excessively reduced.

The exhaust unit 80 may use an exhaust device that has a fan to create a negative pressure and exhaust the gas to the outside. In this case, an odor adsorbent may be provided at the tip of the fan. Also, as the exhaust unit 80, an existing exhaust duct such as a ventilation fan provided in the kitchen may be used. Furthermore, a deodorizing system (air purifier) may be placed under the sink or under the garbage disposal, to which the air outlet 80 may be connected. Furthermore, the exhaust section 80 may be controlled by the control plate 60 described above.

Next, a method for treating kitchen wastewater using the kitchen wastewater treatment apparatus 10 of this embodiment will be described.

First, the exhaust unit 80 is operated to forcibly exhaust the gas inside the grease trap unit 30 and the garbage volume reduction processing unit 50 . It is preferable to continuously operate the exhaust unit 80 during the treatment of the kitchen waste water 1 .

Next, the drain plug 23 of the sink portion 20 is removed. As a result, the kitchen wastewater 1 stored in the sink portion 20 is sent to the grease trap portion 30 through the drain port 21 .

The kitchen wastewater 1 sent to the grease trap section 30 is received by the basket 32 in the kitchen waste collection area 31 . The kitchen waste 2 contained in the kitchen waste water 1 is separated and collected by the basket 32 . The liquid 3 (fat 4 and water 5) that has passed through the basket 32 is sent to the oil-water separation area 34 . In the oil-water separation region 34, the fats and oils 4 and the water 5 in the liquid 3 flow upward between the partition plate 35 and the basket support portion 33, and the fats and oils 4 having a relatively low specific gravity flow upward. Moisture 5, which has relatively high specific gravity, is stored below.

The water 5 stored below the oil-water separation area 34 is sent into the oil-water separation trap 36 through the opening 37 a of the cylindrical member 37 of the oil-water separation trap 36 . The moisture 5 inside the oil-water separation trap 36 is taken out to the outside through the opening 38 a of the drain pipe 38 . Further, the fine solid matter 6 that has passed through the basket 32 is taken out from the solid matter outlet 40 by opening the cock 40a.

The garbage collected in the basket 32 is volume-reduced as follows.
First, the handle 22 of the sink portion 20 is lifted to separate the sink portion 20 and the grease trap portion 30 to expose the grease trap portion 30 . Then, the basket 32 is taken out from the basket support portion 33 .

Next, the garbage 2 in the basket 32 taken out is thrown into the garbage inlet 51 of the garbage volume reduction processing unit 50 . The garbage 2 thrown into the garbage inlet 51 is sent to the garbage treatment tank 53 . In the garbage disposal tank 53, the garbage 2 and the garbage disposal material 55 are agitated by the agitator 56, and the garbage 2 is decomposed by the microorganisms carried on the garbage disposal material 55 and reduced in volume.

The volume-reduced processing residue 7 of the garbage 2 passes through the holes 54 a of the perforated plate 54 and drops into the processing residue outlet 59 . The processing residue 7 dropped into the processing residue discharge port 59 moves on the lower surface 59a of the processing residue discharge port 59 by its own weight and is discharged to the outside.

The treatment residue 7 discharged to the outside is sent to the grease trap section 30 via the connecting pipe 70 . The processing residue 7 sent to the grease trap section 30 is received by the basket 32 in the garbage collection area 31 . The basket 32 collects only the coarse treatment residue 7 . The processing residue 7 collected by the basket 32 is reduced again in the garbage volume reduction processing unit 50 together with the garbage 2 . On the other hand, fine processing residues 7 that have passed through the basket 32 are stored at the bottom of the grease trap portion 30 and then taken out together with the solids 6 from the solids outlet 40 .

Further, when the sink portion 20 and the grease trap portion 30 are separated and the grease trap portion 30 is exposed, the oil and fats 4 stored in the upper portion of the oil/water separation region 34 are recovered. The collected fats and oils 4 are stored in a highly airtight container, for example, so as not to spread offensive odors. By separating the sink portion 20 and the grease trap portion 30, the connecting pipe 70 becomes visible from the grease trap portion 30 side, and cleaning of the connecting pipe 70 becomes easy.

Further, when the sink portion 20 and the grease trap portion 30 are separated and the grease trap portion 30 is exposed, the oil and fats 4 stored in the upper portion of the oil/water separation region 34 are recovered. The collected fats and oils 4 are stored in a highly airtight container, for example, so as not to spread offensive odors. By separating the sink portion 20 and the grease trap portion 30, the connecting pipe 70 becomes visible from the grease trap portion 30 side, and cleaning of the connecting pipe 70 becomes easy.

According to the kitchen wastewater treatment apparatus 10 of this embodiment configured as described above, the grease trap section 30 is arranged below the sink section 20, so that the size of the apparatus can be reduced. Further, by forcibly exhausting the gas in the grease trap portion 30 to the outside with the exhaust portion 80, it is possible to prevent the diffusion of the odor caused by the garbage 2 and the fats and oils 4 collected in the grease trap portion 30. Furthermore, the sink portion 20 and the grease trap portion 30 are separable, and by separating the sink portion 20, the garbage 2 and the fats and oils 4 collected by the grease trap portion 30 can be removed relatively easily to the outside. can be taken out. Therefore, when the garbage 2 or the fats and oils 4 are decomposed in the grease trap part 30 and an offensive odor is generated, the garbage 2 and the oil and fats 4 as the source of the offensive odor can be quickly removed so as not to spread the offensive odor.

In addition, since the kitchen waste water treatment apparatus 10 of the present embodiment includes the kitchen waste volume reduction processing unit 50, the kitchen waste 2 collected in the kitchen waste collection area 31 of the grease trap unit 30 is quickly removed by the kitchen waste volume reduction processing unit 50. It is possible to reduce the volume, thereby suppressing the generation of odors due to putrefaction of the garbage 2. Since the exhaust unit 80 is connected to the garbage volume reduction processing unit 50, by forcibly exhausting the gas in the garbage volume reduction processing unit 50, it is possible to prevent the odor from spreading due to the volume reduction of the garbage 2. . Furthermore, since the processed residue discharge port 59 of the garbage volume reduction processing unit 50 and the grease trap unit 30 are connected via the connecting pipe 70, the gas inside the grease trap unit 30 is discharged together with the gas inside the garbage volume reduction processing unit 50. can be forcibly exhausted, thereby reducing the size of the device. In addition, the connection pipe 70 allows the operator to send the processed residue 7 to the grease trap section 30 without directly touching the processed residue 7 . Furthermore, since the processing residue 7 sent to the grease trap portion 30 is deposited under the moisture 5, the offensive odor of the processing residue 7 is less likely to flow outside. Therefore, the processing residue 7 can be stored for a relatively long period of time. When the processing residue 7 accumulates to some extent, it can be taken out together with the fine solids 6 contained in the kitchen wastewater 1 through the solids outlet 40 of the grease trap portion.

Although embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. Embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. Further, the embodiments include, for example, those that can be easily imagined by a person skilled in the art, those that are substantially the same, those that fall within an equivalent range, and the like.

In the kitchen wastewater treatment apparatus 10 of the present embodiment, the kitchen waste volume reduction processing unit 50 is a biodegradable treatment apparatus that decomposes the kitchen waste 2 using microorganisms carried in the kitchen waste treatment material 55. It is not limited. For example, as the garbage volume reduction processing unit 50, various processing devices used as garbage processing devices such as a drying type processing device, an incineration type processing device, and a hybrid type processing device using both drying and biodegradation are used. may be used.

In addition, in the kitchen wastewater treatment apparatus 10 of the present embodiment, the grease trap section 30 and the kitchen waste volume reduction processing section 50 are connected via the connecting pipe 70, but the connection is not limited to this. For example, instead of connecting via the connecting pipe 70 , the grease trap section 30 and the garbage volume reduction processing section 50 may each be connected to the exhaust section 80 . Further, when the amount of kitchen waste 2 mixed in the kitchen waste water 1 to be treated is small, the kitchen waste volume reduction processing unit 50 may not be provided.

Furthermore, in the kitchen wastewater treatment apparatus 10 of the present embodiment, the solid matter outlet 40 is provided at the bottom of the grease trap portion 30, and the solid matter 6 deposited on the bottom portion of the grease trap portion 30 is removed from the solid matter outlet. 40 can be taken out to the outside, but it is not limited to this. For example, instead of providing the solid matter outlet 40, a pump may be provided to pump the solid matter 6.
