Hereinafter, embodiments of the present invention will be described. In addition, the same elements are designated by the same reference numerals throughout the present embodiment.

(First Embodiment of the present invention)
The bio-toilet system according to this embodiment will be described with reference to FIGS. 1 to 10. The bio-toilet system according to the present embodiment is a circulation type bio-toilet system that can be reused as cleaning water by treating the water used for cleaning the toilet with microorganisms. The required energy may be a completely independent circulating bio-toilet system that can function independently by using natural energy such as sunlight.

FIG. 1 is a system configuration diagram showing the configuration of the bio-toilet system according to the present embodiment, and FIG. 2 is a schematic diagram showing the configuration of the bio-toilet system according to the present embodiment. The bio-toilet system 1 is the first by aerobic bacteria while storing the raw water tank 3 that physically decomposes the filth washed with water from the toilet 2 and the treated water 31 to be treated including the fine filth. The first adjusting tank 4 for aerobic treatment, the septic tank 5 for performing the first anaerobic treatment with anaerobic bacteria and the second aerobic treatment with aerobic bacteria, and the septic tank 5 treated water are stored. A second adjusting tank 6 that performs anaerobic treatment with anaerobic bacteria, a reaction tank 7 that decomposes organic substances contained in the water to be treated into carbon dioxide and water, and a washing tank 8 that stores treated water purified as reclaimed water. And a control unit 100 that monitors and controls the entire system.

Further, a washing toilet seat 9 is installed on the toilet seat of the toilet 2, and the rainwater storage tank 10 for storing rainwater for use in the washing toilet seat 9 and the rainwater treated water stored in the rainwater storage tank 10 are stored. For use in the washing toilet seat 9, it is provided with a pressurizing unit 11 for pressurizing the rainwater treated water.

Further, it includes a solar panel 12 that converts energy obtained from sunlight into electricity, and a secondary battery 13 that charges the generated electricity.

The configuration of the bio-toilet system is only an example, and the technique of the present invention can be applied to the configurations of the raw water tank 3 and subsequent tanks even if they have other configurations.

3 and 4 are views showing the structure of the raw water tank according to the present embodiment. 3 is an overall perspective view of the raw water tank 3, FIG. 4 is a top view and a cross-sectional view of the raw water tank 3 (FIG. 4 (A) is a top view of the raw water tank 3, and FIG. 4 (B) is a view of FIG. 4 (A). It is a cross-sectional view when viewed from the arrow a). The raw water tank 3 is charged with water 31 to be treated, which is a mixture of the washing water used for washing in the toilet 2 and filth such as excrement. The raw water tank 3 sends out the input area 32 into which the water to be treated 31 is charged and the water 31 to be treated in a state where the solid matter contained in the water 31 to be treated is finely decomposed to the next treatment tank by a pump 33. It has a region 34. The drive control of the pump 33 at this time is performed by the control unit 100.

In FIGS. 3 and 4, an inflow port 35 into which the water to be treated 31 from the toilet 2 flows is disposed in the input area 32, and is connected to the discharge port of the toilet 2 by a pipe. Further, although the details will be described later, a charging port 36 for charging the return sludge from the second adjusting tank 6 is provided. The solid matter in the water to be treated 31 charged from the inflow port 35 and the charging port 36 is finely crushed in the charging region 32 by the rotation of the stirring blade 37 and the aeration by the blower 38. The rotation of the stirring blade 37 is performed by driving the motor 37a, and the driving control of the motor 37a is performed by the control unit 100.

The partition plate 39 that separates the charging area 32 and the sending area 34 is formed of three flat plate-shaped portions, and is arranged from the upper surface to the vicinity of the lower surface in the direction perpendicular to the raw water tank 3 first member 39a. And the second member 39b arranged so as to incline downward from the middle position of the first member 39a toward the charging area 32, and the end portion of the second member 39b in the direction perpendicular to the raw water tank 3. It is composed of a third member 39c arranged from the surface to the lower surface of the raw water tank 3. Each member is adhered to the side wall surface of the raw water tank 3 without a gap, and has a structure in which the water to be treated 31 does not flow from the side surface portion. The first member 39a and the third member 39c do not have to be arranged exactly perpendicular to the raw water tank 3, and may be slightly inclined in the horizontal direction.

In the first member 39a, a small hole 301 is formed in the region above the joining position S joined to the second member 39b in the first member 39a and the second member 39b, and in the input region 32. The small crushed solid matter and the water to be treated 31 are circulated in the delivery region 34, and the solid matter that is not sufficiently crushed is caught in the hole 301 and cannot move to the delivery region 34 side. That is, the partition plate 39 serves as a filter, and the solid matter that is not sufficiently crushed is not moved to the delivery region 34, thereby preventing the pump 33 and the piping from being clogged.

Further, the blower 38 is installed on the delivery region 34 side with the second member 39b interposed therebetween, and has a structure in which aeration is performed toward the injection region 32 side through the hole 301 of the second member 39b. By doing so, the large solid matter caught in the hole 301 is separated from the second member 39b, the large solid matter is diffused into the charging region 32 while preventing the hole 301 from being clogged, and the pulverization treatment is performed again. It will be possible to do.

The hole 301 is not formed in the region below the joint position S of the first member 39a, and the aeration of the blower 38 is efficiently transmitted to the charging region 32 side. The hole 301 may or may not be formed in the third member 39c.

The pump 33 is driven by the control unit 100. When the water level of the first adjustment tank 4 in the subsequent stage is sufficient, the control unit 100 uses the water 31 to be treated in the raw water tank 3 as the first adjustment tank 4 at any time. Pump up to. When the water level of the first adjusting tank 4 is not sufficient, the water to be treated 31 is stored in the delivery area 34 without driving the pump 33, but the float 302 is installed in the delivery area 34 and is set in advance. When the water level exceeds the above water level, the water to be treated 31 is pumped up and sent out regardless of the water level of the first adjusting tank 4.

The water to be treated 31 delivered by the pump 33 from the delivery area 34 of the raw water tank 3 is stored in the first adjusting tank 4. In the first adjusting tank 4, the water to be treated 31 is stored according to the progress of the treatment of the septic tank 5 in the next stage. This is because when the control unit 100 determines that the purification treatment of the septic tank 5 is delayed, that is, the water level of the second adjusting tank 6 rises and the amount of water 31 to be treated discharged from the septic tank 5 increases. If it is determined that the water to be treated is slowed down, the water to be treated 31 is stored in the first adjusting tank 4. Further, when it is determined that the purification treatment of the septic tank 5 is proceeding smoothly, that is, when it is determined that the water level of the second adjusting tank 6 is low and the amount of water 31 to be treated discharged from the septic tank 5 is not so large. In order to proceed with the purification treatment of the septic tank 5, the water to be treated 31 is immediately put into the septic tank 5.

The first adjusting tank 4 is provided with a first bacterial bed region 41 that serves as a bacterial bed for aerobic bacteria, and the bacteria activated in this bacterial bed are biofilmed on the inner wall of the first adjusting tank 4. A film is formed and aerobic treatment is performed by aeration from the blower 42. At the same time, the aeration from the blower 42 increases the dissolved oxygen in the water to be treated 31, and activates the activity of the bacteria in the subsequent treatment. That is, while the water to be treated 31 is stored in the first adjusting tank 4, aerobic treatment can be performed in advance as a pretreatment of the septic tank 5, and the burden of the purification treatment of the septic tank 5 in the subsequent stage can be reduced. Is possible.

The water to be treated 31 is sent from the first adjusting tank 4 to the septic tank 5 by pumping up by the pump 43, and the drive control of the pump 43 is performed by the control unit 100 based on the water level of the second adjusting tank 6. It is done by control. Further, in the fungus bed region 41, for example, a contact material in which bacteria are implanted in a mesh-like fungus bed bag is charged, and the activated bacteria form a biofilm on the inner wall of the first adjusting tank 4. You may do it. By doing so, it is possible to prevent the contact material from being scattered in the tank and prevent the contact material from clogging the piping.

Further, as shown in FIG. 2, a stirring blade 44 and a motor 45 for rotationally driving the stirring blade 44 may be arranged above the first adjusting tank 4. There is a possibility that solid matter will be deposited on the upper part of the first adjustment tank 4 (solid matter finely crushed in the raw water tank 3 will float and be deposited), and the aeration of the blower 42 alone will diffuse the deposited solid matter. When it is difficult to do so, by driving the stirring blade 44, the accumulated solid matter can be crushed again and sent to the processing tank 5 in the subsequent stage. The drive control of the motor 45 is performed by the control unit 100. As for the timing of driving, for example, the motor 45 may be driven periodically, or the motor 45 may be driven periodically, the frictional force is measured, and if the friction is large, it is estimated that solid matter is deposited. Then, the motor 45 may be driven in earnest.

Further, the pump 43 may be installed at a position where it directly receives the aeration of the blower 42. By doing so, it becomes possible to prevent the pump 43 from being clogged by aeration.

Furthermore, a water quality sensor may be installed in the second adjusting tank 6 (not shown), and the control unit 100 may control the drive of the pump 43 of the first adjusting unit 4 based on the information of the water quality sensor. That is, when the water quality of the second adjusting tank 6 is good, it is assumed that the purification treatment has been sufficiently performed, and the water to be treated 31 is sent to the septic tank 5, and when the water quality is poor, the purification treatment in the septic tank 5 is performed. However, the water to be treated 31 may be stored in the first adjusting tank 4 as much as possible, and the purification treatment may be slowed down. Further, at this time, although the details will be described later, the return from the second adjusting tank 6 to the raw water tank 3 may be controlled to increase the pace. By doing so, the water to be treated 31 having insufficient purification treatment can be purified again to improve the water quality.

The water to be treated 31 sent out from the first adjusting tank 4 is subjected to full-scale microbial treatment in the septic tank 5. FIG. 5 is a diagram showing the structure of a septic tank in the bio-toilet system according to the present embodiment. The septic tank 5 has an anaerobic treatment region 51 for performing the first anaerobic treatment, an aerobic treatment region 52 for performing the second aerobic treatment, and a delivery region 53 for sending the water to be treated 31 to the reaction tank 6 in the subsequent stage. Have.

The water to be treated 31 charged from the first adjusting tank 4 is first subjected to the first anaerobic treatment in the anaerobic treatment region 51. In order to perform this first anaerobic treatment over a certain period of time, as shown in FIG. 5, the anaerobic treatment region 51 is divided into two, and the anaerobic treatment is sequentially performed in each section. Each section is connected by a communicating pipe, and the water to be treated 31 flows between the sections by natural flow. The anaerobic treatment region 51 and the aerobic treatment region 52 communicate with each other so that the treated water 31 can flow above the respective regions, and the treated water 31 subjected to the first anaerobic treatment passes through the communication passage. It is sent to the aerobic processing area 52. In the aerobic treatment region 52, air is sent from the blower 57 to the contact material 56, which is housed in a mesh-like frame 55 and in which aerobic bacteria are resident, and the aerobic treatment is performed. The aerobic treatment region 52 and the delivery region 53 communicate with each other below each region, and the aerobic treated water 31 is delivered to the next second adjusting tank 6. The treatment of the septic tank 5 is performed by natural flow without using a pump or the like. Therefore, the same amount of water to be treated is sent to the second adjusting tank 6 at the same time as the amount of water to be treated 31 is charged.

Further, a part of the water to be treated 31 that has been aerobically treated in the aerobic treatment region 52 is returned to the anaerobic treatment region 51 through a pipe using a pump or aeration in order to perform sufficient microbial treatment again. , The treatment is repeated so as to obtain a cleaner water to be treated 31. The blower 57 and the pump are driven and controlled by the control unit 100.

The water to be treated 31 treated in the septic tank 5 is stored in the second adjusting tank 6. FIG. 6 is a diagram showing the structure of the second adjusting tank in the bio-toilet system according to the present embodiment. In the second adjusting tank 6, the remaining amount of washing water described later and the degree of progress of the treatment of the septic tank 5, that is, the water level of the second adjusting tank 6, the water level of the parking area 73 in the reaction tank 7 described later, and if necessary. The control unit 100 determines the progress of the treatment based on the water level of the washing tank 8, and the water to be treated 31 is stored or sent to the reaction tank 7 in the next stage according to the judgment of the control unit 100. do. That is, when the water level in the parking area 73 of the washing tank 8 or the reaction tank 7 is low, it is determined that the washing water tends to be insufficient, and the water to be treated 31 is sent to the reaction tank 7. When the water level in the parking area 73 of the washing tank 8 or the reaction tank 7 is rising, it is determined that the washing water is sufficiently secured, and the water to be treated 31 is stored in the second adjusting tank 6. When the water level of the second adjusting tank 6 also rises, the progress of the treatment is adjusted by storing the water to be treated 31 in the first adjusting tank 4 as described above. The water to be treated 31 is sent from the second adjusting tank 6 to the reaction tank 7 by the pump 62, and the drive control of the pump 62 is performed based on the judgment of the control unit 100 as described above.

If the water to be treated 31 is sent to the second adjusting tank 6 in a state where the purification treatment in the septic tank 5 is insufficient, sludge may settle below the second adjusting tank 6. Therefore, as shown in FIG. 6, the bottom surface portion of the second adjusting tank 6 in which the water to be treated 31 is stored is inclined to, and sludge is settled on the tip portion 61 thereof. The height of the inclined tip portion 61 corresponds to the position of the upper surface of the raw water tank 3, and the structure is such that the settled sludge is pulled out and returned to the raw water tank 3. Specifically, the tip portion 61 and the upper surface portion of the raw water tank 5 are connected by a pipe 67, and a solenoid valve 68 is installed in the pipe 67. The solenoid valve 68 has a structure that is periodically or irregularly opened under the control of the control unit 100. When the solenoid valve 68 is opened, sludge accumulated in the tip portion 61 is pulled out and the raw water tank 3 is opened. Can be returned to. The raw water tank 3 and the second adjusting tank 6 are arranged adjacent to each other, and by minimizing the length of the pipe 67, sludge settled in the second adjusting tank 6 can be easily transferred to the raw water tank 3. It is possible to return it and reduce the maintenance work.

The second adjusting tank 6 may also be provided with a fungus bed region 63 similar to that of the first adjusting tank 4, and the activated bacteria may form a biofilm on the inner wall of the second adjusting tank 6. By doing so, the anaerobic treatment can be performed again on the water 31 to be treated stored in the second adjusting tank 6, and the contact material is used while preventing the contact material from being scattered in the tank. It is possible to prevent clogging of piping.

Further, as described above, a water quality sensor may be installed in the second adjusting tank 6 (not shown), and the pace of return to the raw water tank 3 may be controlled based on the information from the water quality sensor. That is, when the water quality is poor, the pace of return to the raw water tank 3 (or the amount of return) is increased, and when the water quality is good, the pace of return to the raw water tank 3 (or the amount of return) is decreased. You may let it.

The water to be treated 31 sent out from the second adjusting tank 6 is charged into the reaction tank 7. FIG. 7 is a diagram showing the structure of the reaction tank in the bio-toilet system according to the present embodiment. When the water to be treated 31 is charged into the reaction tank 7, it is sprayed and charged from the spraying portion 71 installed above the reaction tank 7. The reaction tank 7 has a decomposition region 72 (upper region) that decomposes and removes organic substances contained in the water to be treated 31 into carbon dioxide and water, and a parking region 73 (a parking region 73) that stores the water to be treated 31 from which the organic substances have been removed. It has a lower area). The decomposition region 72 is filled with a biochip 74 (for example, cedar chip or the like) implanted with bacteria that decompose organic matter into carbon dioxide and water, and the treated water 31 sprayed from the spraying portion 71 is the water to be treated. Organic matter is removed as it passes through the biochip 74. The water to be treated 31 that has passed through the biochip 74 is stored in the parking area 73 arranged below.

The water to be treated 31 stored in the parking area 73 is purified to a level that can be used as washing water. However, since the water to be treated 31 stored in the parking region 73 passes through the decomposition region 72 while in contact with the biochip 74, it is colored brown. Even if the purification level is sufficient, it is not comfortable for the user when brown water comes out as wash water. Therefore, in order to remove this brown coloring, a coloring removing filter 75 is used. At the same time, in order to eliminate the outflow of bacteria to the next-stage washing tank 8, the bacteria removal filter 76 is used.

FIG. 8 is a diagram showing the structure of the parking area of the reaction tank in the bio-toilet system according to the present embodiment. In FIG. 8A, the area before and after the filter processing is divided into areas and processed by one filter, and in FIG. 8B, the areas before and after the filter processing are divided into areas and processed by two filters. In the case, FIG. 8 (C) does not divide the area before and after the filter processing into areas, and when processing is performed by one filter, FIG. 8 (D) does not divide the areas before and after the filter processing into areas and uses two filters. The structure when processing is shown. As described above, here, the purpose is to remove brown coloring and bacteria. For brown coloring, a color removal filter 75 using a reverse osmosis membrane is used, and for bacteria, a fungus removal filter 76 using a hollow fiber is used. It is efficient to use.

In the case of FIG. 8A, the color removing filter 75 and the fungus removing filter 76 are integrated, and only the filtered water 31 to be treated is sent to the washing tank 8. In this case, since the function is realized by one filter, the configuration can be simplified, but the filter may be easily clogged. Further, since only the filtered water 31 to be treated is sent to the washing tank 8, it is necessary to stop the entire bio-toilet system 1 when the filter is replaced or the filter is clogged. In the case of FIG. 8B, since the bacteria are first removed by the bacteria removing filter 76 and then passed through the coloring removing filter 75, the coloring is removed after the large-sized bacteria are removed first, and the clogging of the filter is suppressed. Can be done. However, even in this case, it is necessary to stop the entire bio-toilet system 1 when the filter is replaced or the filter is clogged.

In the case of FIG. 8C, the color removing filter 75 and the fungus removing filter 76 are integrated, and the water to be treated 31 is sent to the washing tank 8 before and after the filter treatment. In this case, since the function is realized by one filter as in FIG. 8A, the configuration can be simplified, but the filter may be easily clogged. On the other hand, since the water to be treated 31 is sent to the washing tank 8 before and after the filter treatment, it is not necessary to stop the entire bio-toilet system 1 even when the filter is replaced or the filter is clogged. In the case of FIG. 8D, since the bacteria are first removed by the bacteria removing filter 76 and then passed through the coloring removing filter 75, the coloring is removed after the large-sized bacteria are removed first, and the clogging of the filter is suppressed. Can be done. Further, it is not necessary to stop the entire bio-toilet system 1 even when the filter is replaced or the filter is clogged.

The parking area 73 is also provided with a fungus bed area 77 similar to that of the first adjustment tank 4 and the second adjustment tank 6, so that the activated bacteria form a biofilm on the inner wall of the parking area 73. good. By doing so, the anaerobic treatment can be performed again on the water to be treated 31 stored in the parking area 73.

By performing the filter treatment as shown in FIG. 8, it is possible to generate clear and clean water to be treated 31 (at this point, the treated water is reused for cleaning). The transparent water to be treated 31 is pumped up from the parking area 73 to the washing tank 8 under the control of the control unit 100. When water is flushed after the toilet 2 is used, the treated water in the washing tank 8 is sent out by the pump 81, the toilet 2 is washed, and the water is circulated in the system again.

The washing water can be circulated by the series of treatments as described above. In the present embodiment, the electric power generated by the solar panel 12 is used as the electric power for pumping up and driving the control unit 100 required in each process. The electric power generated by the solar panel 12 is stored in the secondary battery 13, and each pump or control unit 100 processes the electric power while consuming the electric power as needed. The solar panel 12 may be installed on the roof, or the sheet type may be attached to the side wall of the bio-toilet system 1.

Further, in the present embodiment, the user can use the purified water toilet seat 9 after adding the work. As the water for the purified toilet seat 9, rainwater stored in the rainwater storage tank 10 is used. In the rainwater storage tank 10, for example, chemicals such as chlorine and a photocatalyst are used for sterilization and disinfection, and purified water at a level that does not cause any problem even if it comes into contact with the body is secured as treated rainwater. When the purified water toilet seat 9 is used, it is necessary to eject the treated rainwater for washing with a predetermined force, so that the pressure treatment is performed by the pressurizing unit 11. All of these controls are performed by the control unit 100, and the required electric power is supplemented by the electric power stored in the secondary battery 13.

When treated rainwater is used in the washing toilet seat 9, the amount of water flowing into the toilet 2 increases by that amount. In addition, since water is also added by urination or the like, the total amount of water in the bio-toilet system 1 may increase to the extent that it affects the purification treatment. Therefore, in the present embodiment, it has a function of efficiently discharging the increased water to the outside of the bio-toilet system 1.

FIG. 9 is a diagram showing an example of a mechanism for discharging the increased water in the system in the bio-toilet system according to the present embodiment. 9 (A) is a front view of the bio-toilet system, and FIG. 9 (B) is a side view of the bio-toilet system. In FIG. 9, the increased water content is purified to a level that can be reused as treated water in the washing tank 8, and then released to the solar panel 12. As shown in FIG. 9, for example, a rain gutter 121 having a small hole at the upper end (upper side portion) of the solar panel 12 is provided, and this rain is pumped up through a pipe 122 from the room of the bio-toilet system. The treated water carried to the gutter 121 is discharged to the surface of the solar panel 12. The surface of the solar panel 12 is cooled by the treated water, the temperature is lowered, and it becomes possible to significantly improve the power generation efficiency especially in the summer. At the same time, the surface of the solar panel 12 is cleaned, and the power generation efficiency can be improved.

The same applies when the solar panel 12 is attached to the side wall of the bio-toilet system 1, and the treated water is applied to the surface of the solar panel 12 from the upper end portion (upper side portion of the solar panel 12) of the solar panel 12. By releasing the above, the temperature of the solar panel 12 can be lowered and the power generation efficiency can be increased.

Discharge of treated water to the solar panel 12 as shown in FIG. 9 is extremely effective when the power generation efficiency is lowered due to the temperature rise of the solar panel 12, especially in summer, but there is a great advantage in winter. I can't do it. Further, depending on the environment, the discharged treated water may be cooled by the outside air temperature to become ice, which may deteriorate the solar panel 12. In such a case, by sending an air flow into each treatment tank, the gas flow can be brought into contact with the water to evaporate the water. For example, in the raw water tank 3, the first adjusting tank 4, the aerobic treatment region 53, etc., which are aerated using a blower, the water can be evaporated and the water can be reduced only by opening the upper part.

Further, in order to evaporate the water more efficiently, the air flow generated by the ventilation fan installed in the toilet 2 may be used. It is possible to promote the evaporation of water simply by passing the airflow generated by the ventilation fan through each tank. FIG. 10 is a diagram showing a configuration in the bio-toilet system according to the present embodiment when the air flow of the ventilation fan is used for discharging the increased water in the system. FIG. 10 is a top view showing the internal structure of the bio-toilet system, and shows the direction of the air flow from the ventilation fan 131.

In FIG. 10, the colored portion is the path through which the air flow flows, and can flow in a state where it can come into contact with the treated water 31 and the treated water stored in each tank. There are multiple directions of the air flow (indicated by the broken line arrow in FIG. 10), and the route can be changed according to the amount of water in the bio-toilet system 1. That is, if the amount of water in the bio-toilet system 1 is very high and it is necessary to evaporate a large amount of water, the valve (1) and / or the valve so that the air flow flows through as many tanks as possible. If the airflow path is controlled by (2) and it is not necessary to evaporate the water so much, the valve (1) and / or the valve (2) is used to allow the airflow to flow through only the minimum tank. Control the route. The control of the valve (1) and / or the valve (2) is performed by the control unit 100.

As the water used for the washing toilet seat 9, the treated water stored in the washing tank 8 may be sterilized and disinfected.

(Other Embodiments of the present invention)
The bio-toilet system according to this embodiment will be described with reference to FIGS. 10 and 11. In this embodiment, the description overlapping with the first embodiment will be omitted.

FIG. 10 is a diagram showing the structure of a raw water tank in the bio-toilet system according to the present embodiment. 10 (A) is a top view of the raw water tank 3, and FIG. 10 (B) is a cross-sectional view taken from the arrow a of FIG. 10 (A). In FIG. 10, the stirring blade 37 as in the case of FIG. 3 is not provided, and the solid matter in the water to be treated 31 is treated only by aeration by the blower 38.

In FIG. 10, a charging area 32 into which the water to be treated 31 is charged and a delivery area 34 in which the water to be treated 31 in a state where the solid matter contained in the water to be treated 31 is finely decomposed is sent to the next treatment tank by a pump 33. And have. The charging area 32 and the sending area 34 are separated by a first member 39a having a small hole 301. An inflow port 35 into which the water to be treated 31 from the toilet 2 flows is disposed in the input area 32, and is connected to the discharge port of the toilet 2 by a pipe. Further, as will be described in detail later in FIG. 11, a charging port 36 for charging the return sludge from the second adjusting tank 6 is provided.

The solid matter in the water to be treated 31 charged from the inflow port 35 and the charging port 36 settles in the sludge receiving portion 101 composed of the second member 39b and the third member 39c arranged in the charging region 32, and here. It is finely crushed by aeration by the blower 38. The sludge receiving portion 101 has a second member 39b that is inclined with respect to the vertical direction of the raw water tank 3 and a third member 39c that is connected to the second member 39b and is horizontally arranged in the raw water tank 3. Each member has a small hole 301. The small solid matter crushed in the charging region 32 and the water to be treated 31 are circulated to the delivery region 34 through the sludge receiving portion 101 and the hole 301 of the first member, and the solid matter not sufficiently crushed is caught in the hole 301. Therefore, it cannot be moved to the transmission area 34 side.

Further, the second member 39b and the third member 39c are locked by the locking portions 102a and 102b fixed to the inner wall surface. The locking portion 101 is arranged at a position higher than the locking portion 102, and has a structure in which sludge can be collected in the horizontal portion of the third member 39c by utilizing the inclination of the second member 39b and can be aerated efficiently. ing.

Further, the locking portion 101 is arranged at a position higher than that of the first member 39a and on the input region 32 side. By doing so, even if a large amount of water 31 to be treated is charged, the sludge overflowing from the sludge receiving portion 101 is not directly charged into the delivery area 34, but overflows to the charging area 32 side. It is possible to prevent the pump 33 and the like on the delivery area 34 side from being clogged.

The water level of the raw water tank 3 is measured by the float 302 and adjusted so as not to exceed the height of the first member 39a.

FIG. 11 is a diagram showing the structure of the second adjusting tank in the bio-toilet system according to the present embodiment. The difference from the case of FIG. 5 is that the raw water tank 3 is arranged and integrally formed below the second adjusting tank 6, and the sludge discharged from the tip portion 61 of the second adjusting tank 6 is directly below. The structure is such that it is put into the raw water tank 3. The sludge returned from the tip portion 61 may be returned to the raw water tank 3 through a pipe or the like through the discharge port of the tip portion 61 and the input port 36 of the raw water tank 3, or may be directly connected to the raw water tank 3. It may be returned.

In addition, in FIG. 11, the raw water tank 3 of FIG. 10 is arranged downward in the second adjusting tank 6, but if the drive mechanism of the stirring blade 37 is eliminated in the raw water tank 3 of FIG. 3, The raw water tank 3 of FIG. 3 can be integrally formed with the second adjusting tank 6.

In this way, by integrally forming the raw water tank 3 and the second adjusting tank 6, space saving can be realized, the bio-toilet system can be made compact, and the number of toilet units can be increased.
