The partition walls 14 </ b> A and 14 </ b> B are formed in the vertical direction in a cross-sectional view and extend in the full length direction of the cylindrical tank 1 so as to pass through the axis S.

  The partition wall 14A of the toilet room 6 and the first treatment tank 9 is a non-communication partition wall that is formed in the entire range from the ceiling surface to the bottom surface in the cylindrical tank 1 and completely separates the space. The partition wall 14B of the third treatment tank is a communication partition wall formed in a range from the ceiling surface in the cylindrical tank 1 to the front of the bottom surface. A communication port 16 for communicating adjacent spaces divided by the partition wall 14B is formed between the lower end of the communication partition wall 14B and the bottom surface in the cylindrical tank 1.

  The peripheral wall, the front wall 2 and the rear wall 3 of the cylindrical tank 1 described above are integrally formed with a partition 4 and partition walls 14A and 14B by a curable synthetic resin such as FRP.

  By the two types of partition walls 14A and 14B configured as described above, the toilet room 6 and the three treatment tanks 9, 11, and 12 are each equally divided into left and right with the axis S as a boundary.

  One space of the toilet room 6 divided into two by the partition wall 14A becomes the first toilet room 6a, and the other space becomes the second toilet room 6b. Each of the two toilet rooms 6a and 6b is provided with one Western-style toilet bowl 17, and the front wall 2 is formed with an entrance 18 for each of the toilet rooms 6a and 6b.

One space of the third treatment tank 12 divided into two by the partition wall 14B becomes a second aerobic treatment chamber (aeration treatment chamber, aerobic treatment chamber) 12a adjacent to the first anaerobic treatment chamber 11b, and The other space becomes a second anaerobic processing chamber (anaerobic processing chamber) 12b.

  This circulating toilet treats and purifies sewage from the tray chamber 6 by the machine room 7, the water storage tank 8 and the three treatment tanks 9, 11, and 12 formed as described above. The circulation process is performed by returning to the washing tank 17a of the toilet bowl 17, and the configuration of the circulation process will be described in detail below.

  A sewage tank 21 is formed under the floor of the machine room 7 by the peripheral wall of the cylindrical tank 1, and the control panel 13, the toilet 17 of the toilet room 6, and the sewage tank 21 are connected to the machine room 7. The sewage pipe 22 to be connected, the introduction pipe 23 to connect the sewage tank 21 and the introduction chamber 9a, the washing pipe 24 to connect the water storage tank 8 and the toilet bowl 17 (specifically, the washing tank 17a), and an external not shown A water distribution pipe 26 that connects the water pipe and the cleaning tank 17a of the toilet bowl 17 is provided.

  In the sewage tank 21, sewage containing excrement from the toilet 17 flows in and is stored by the sewage pipe 22. An introduction pump 27 is provided in the sewage tank 21, and the introduction pump 27 introduces sewage in the sewage tank 21 into the introduction chamber 9 a through the introduction pipe 23. Incidentally, a partition 28 for separating the introduction pump 27 side of the sewage tank 21 from other parts is formed in the sewage tank 21, and the sewage in the sewage tank 21 is made of solid matter by the partition 28. In a state separated to some extent, it reaches the introduction pump 27 side and is introduced into the introduction chamber 9a.

  The introduction chamber 9a includes a wall 4 separating the water storage tank 8 and the first treatment tank 9, a wall 4 separating the first treatment tank 9 and the second treatment tank 11, and a bottom surface of the cylindrical tank 1 from the bottom surface to the ceiling surface. The inner circumferential surface (circular arc surface) having a radial shape in cross section and the partition wall 14A are formed, and the inner wall surface of the introduction chamber 9a is formed by these members, and the maximum water level of the introduction chamber 9a is within the cylindrical tank 1 It is set on the ceiling side. Incidentally, in order to set the maximum water level of the introduction chamber 9a to be equal to or higher than the height of the shaft center S, the introduction chamber is formed by the inner circumferential surface of the circular cylindrical tank 1 extending from the bottom surface of the cylindrical tank 1 to at least the height of the shaft center S. It is necessary to form at least a part of the inner wall surface of 9a.

  A blower 29 is installed on the bottom side of the introduction chamber 9a. The blower 29 is connected to an air pipe 31 from the machine chamber 7 side, and the blower 29 has a high pressure (specifically, 750 [L / min]). By the air jetted upward, an aeration process is performed in which the sewage in the introduction chamber 9a is convected while being mixed with air. This aeration treatment is a kind of aerobic treatment in which sewage is oxidized and purified by an aerobic microorganism that is a microorganism that grows and proliferates in the presence of oxygen. Moreover, since the air jetted from the blower 29 is at a high pressure, the aerobic treatment is further promoted, and the solid matter contained in the sewage is finely pulverized.

  Thus, the sewage in the introduction chamber 9a subjected to the aeration treatment is subjected to the first aerobic treatment by the introduction hole 4a formed in the upper part of the partition wall 4 separating the introduction chamber 9a and the first aerobic treatment chamber 11a. It is introduced into the chamber 11a. That is, the height of the lower end of the introduction hole 4a is set to the maximum water level of the introduction chamber 9a.

  The first aerobic processing chamber 11a includes a wall 4 separating the first processing tank 9 and the second processing tank 11, a wall 4 separating the second processing tank 11 and the third processing tank 12, and the cylindrical tank 1. The inner peripheral surface (arc surface) having a radial cross section from the bottom surface to the ceiling surface and the partition wall 14B are formed by these members, and the inner wall surface of the first aerobic processing chamber 11a is formed by these members. The maximum water level of the one aerobic processing chamber 11a is set to be equal to or higher than the height of the axis S. Incidentally, in order to set the maximum water level of the first aerobic processing chamber 11a to be equal to or higher than the height of the axial center S, the inner circumferential surface of the circular cylindrical tank 1 extending from the bottom surface of the cylindrical tank 1 to at least the height of the axial center S. It is necessary to form at least a part of the inner wall surface of the first aerobic processing chamber 11a.

  A blower 32 is installed on the bottom side of the first aerobic processing chamber 11a, and an air pipe (not shown) from the machine chamber 7 side is connected to the blower 32, and the blower 32 has a normal pressure (upward). The air is lower in pressure than the blower 29 in the introduction chamber 9a, specifically, 80 [L / min]). By the air jetted upward, aeration processing is performed in which sewage in the first aerobic processing chamber 11a is convected while being mixed with air. Incidentally, since this aeration process is performed with air having a pressure lower than that of the introduction chamber 9a, the processing efficiency is set lower than that of the introduction chamber 9a.

  In addition, a first aerobic processing chamber is directed downward at a lower end portion (end portion on the side of the communication port 16) of the communication partition wall 14B that partitions the first aerobic processing chamber 11a and the first anaerobic processing chamber 11b. A guide portion 33 that is curved on the 11a side is integrally formed, and the guide portion 33 suppresses inflow of convective sewage into the first anaerobic treatment chamber 11b and also the first aerobic treatment quality 11a. Inside, sewage is convected more smoothly and aerobic treatment is promoted. In this way, the sewage in the first aerobic processing chamber 11a subjected to the aeration process flows into the first anaerobic processing chamber 11b through the communication port 16.

  The first anaerobic treatment chamber 11b includes a wall 4 separating the first treatment tank 9 and the second treatment tank 11, a wall 4 separating the second treatment tank 11 and the third treatment tank 12, and the cylindrical tank 1. The inner circumferential surface (arc surface) having a radial cross section from the bottom surface to the ceiling surface and the partition wall 14B are formed by these members, and the inner wall surface of the first anaerobic treatment chamber 11b is formed by these members. The maximum water level of the one anaerobic treatment chamber 11b is set to be equal to or higher than the height of the axis S. Incidentally, since the maximum water level of the first anaerobic treatment chamber 11b is set to be equal to or higher than the height of the axial center S, the inner circumferential surface of the circular arc-shaped cylindrical tank 1 extending from the bottom surface of the cylindrical tank 1 to at least the height of the axial center S. It is necessary to form at least a part of the inner wall surface of the first anaerobic treatment chamber 11b.

  In the first anaerobic treatment chamber 11b, sewage is not convected and air is not mixed. This reduces the oxygen concentration in the sewage, and anaerobic microorganisms that grow and proliferate in the absence of oxygen grow and proliferate, and the anaerobic microorganisms reduce and purify the sewage by reductive decomposition. Processing is performed.

  In this way, the sewage in the first anaerobic treatment chamber 11b subjected to the anaerobic treatment is introduced in the upper part of the partition wall 4 separating the first anaerobic treatment chamber 11b and the second aerobic treatment chamber 12a. It introduce | transduces into the 2nd aerobic processing chamber 12a by the hole 4a. That is, the height of the lower end of the introduction hole 4a is set to the maximum water level of the second treatment tank 11 (the first aerobic treatment chamber 11a and the first anaerobic treatment chamber 11b), and this maximum water level is higher than that of the introduction chamber 9a. Also lower.

  The second aerobic processing chamber 12a includes a wall portion 4 that separates the second processing tank 11 and the third processing tank 12, a rear surface wall 3, and a radial inner section from the bottom surface of the cylindrical tank 1 to the ceiling surface. These members are formed by the peripheral surface (arc surface) and the partition wall 14B, and the inner wall surface of the second aerobic processing chamber 12a is formed by these members, and the maximum water level of the second aerobic processing chamber 12a is the axis S. It is set to a height higher than. Incidentally, in order to set the maximum water level of the second aerobic processing chamber 12a to be equal to or higher than the height of the axial center S, the inner circumferential surface of the circular cylindrical tank 1 extending from the bottom surface of the cylindrical tank 1 to at least the height of the axial center S. It is necessary to form at least a part of the inner wall surface of the second aerobic processing chamber 12a.

  A blower 34 is installed on the bottom side of the second aerobic processing chamber 12a, and this blower 34 is connected to an air pipe (not shown) from the machine chamber 7 side. More specifically, the air is injected at a pressure lower than that of the blower 29 in the introduction chamber 9a, specifically, 80 [L / min], which is the same as the pressure of the blower 32 in the first aerobic processing chamber 11a. By the air jetted upward, aeration processing is performed in which sewage in the second aerobic processing chamber 12a is convected while being mixed with air.

  Further, the second aerobic processing chamber is directed downward at the lower end portion (end portion on the side of the communication port 16) of the communication partition wall 14B that partitions the second aerobic processing chamber 12a and the second anaerobic processing chamber 12b. The guide part 33 curvedly formed on the 12a side is integrally formed, and the guide part 33 prevents the convective sewage from flowing into the second anaerobic treatment chamber 12b and convects the sewage more smoothly. Promote aerobic treatment.

  In this way, the sewage in the second aerobic processing chamber 12a subjected to the aeration process is subjected to the second anaerobic process by the communication port 16 formed between the guide portion 33 and the bottom surface of the cylindrical tank 1. It flows into the chamber 12b.

  The second anaerobic processing chamber 12b has a wall portion 14 that separates the second processing tank 11 and the third processing tank 12, the rear wall 3, and a radial inner section from the bottom surface of the cylindrical tank 1 to the ceiling surface. The inner wall surface of the second anaerobic treatment chamber 12b is formed by the peripheral surface (arc surface) and the partition wall 14B, and the maximum water level of the second anaerobic treatment chamber 12b is the axis S. It is set to a height higher than. Incidentally, in order to set the maximum water level of the second anaerobic treatment chamber 12b to be equal to or higher than the height of the axial center S, the inner circumferential surface of the arc-shaped cylindrical tank 1 extending from the bottom surface of the cylindrical tank 1 to at least the height of the axial center S. It is necessary to form at least a part of the inner wall surface of the second anaerobic treatment chamber 12b.

  In the second anaerobic treatment chamber 12b, sewage is not convected and air is not mixed. Thereby, the anaerobic process described above is performed. A treated water pipe 36 is provided in a range from the upper part of the second anaerobic treatment chamber 12b to a portion near the second treatment tank of the storage chamber 9b, and one end side of the treated water pipe 36 (in the illustrated example, the end of the storage chamber 9b side). Part) is provided with a storage pump 37 for sending the sewage in the second anaerobic processing chamber 12b subjected to anaerobic processing to the storage chamber 9b as treated water.

  The storage chamber 9b and the first aerobic treatment chamber 11a are connected by a reduction pipe 38, and the storage chamber 9b and the water storage tank 8 are connected by a water purification pipe 39. The treated water sent out by the reduction pump 41 installed in the storage chamber 9b is returned to the first aerobic treatment chamber 11a as sewage through the reduction pipe 38. Further, the treated water sent out by the water purification pump 42 installed in the upper part of the storage chamber 9 b and near the water storage tank 8 is introduced into the water storage tank 8 through the water purification pipe 39.

  A dividing wall 43 that divides the storage chamber 9b into a space close to the water storage tank 8 and a space close to the second processing tank 11 is provided, and the space between the lower end of the dividing wall 43 and the bottom surface in the cylindrical tank 1 is The treated water that is open and sent from the second anaerobic treatment chamber 12b to the storage chamber 9b reaches the purified water pump 42 side through the opened portion, and passes through the purified water pipe 39 to the water storage tank 8. Sent in. On the other hand, when the quality of the treated water in the storage chamber 9b is below a predetermined level, the reduction pump 41 returns the water from the reduction pipe 38 to the first aerobic treatment chamber 11a.

  In the water storage tank 8, a plurality of (two in the illustrated example) parallel-arranged cylindrical purification tanks 44 extending in the vertical direction are arranged in a direction intersecting (orthogonal) with the axis S in plan view. . The space other than that occupied by the septic tank 44 in the water storage tank 8 is a water storage space 8a in which the purified water purified by the septic tank 44 is stored.

  Each purification tank 44 includes a cylindrical purification cylinder 46 extending in the vertical direction, and a lower tank 47 disposed immediately below the purification cylinder 46. In the upper part of the purification cylinder 46, a circular ring-shaped water sprinkling pipe 48 is installed along the circular cross section of the purification cylinder 46 in plan view from the inside, and wood chips are filled immediately below the water spraying pipe 48 in the purification cylinder 46. The treated layer 49 is formed. Wood chips have a large surface area and are inhabited by both aerobic and anaerobic microorganisms. Then, the treated water sprayed in a circular shape downward from the sprinkling pipe 48 is purified through both aerobic treatment and anaerobic treatment in the process of flowing down the tip layer 49 and leaks into the lower tank 47. Is stored.

  Adjacent septic tanks 44, 44 are connected by a connecting pipe 51. Specifically, a lower tank 47 of one septic tank 44 and a watering pipe 48 of the other septic tank 44 are connected by a connecting pipe 51, and a watering pump 52 installed on the lower tank 47 side of the one septic tank 44 is used. The treated water in the lower tank 47 is sent to the watering pipe 48 of the other septic tank 44, and the watering is performed on the upper part of the septic tank 44.

  Further, the water purification pipe 39 of the purification tank 44 that performs the purification process first by the tip layer 49 is connected to the water purification pipe 39 described above, and the treated water sent out by the water purification pump 42 is sprinkled from the watering pipe 48. .

  On the other hand, a water storage pump 53 is installed on the side of the lower tank 47 of the purification tank 44 that finally performs the purification treatment with the chip layer 49, and a water storage pipe 54 is provided between the lower tank 47 and the water storage space 8a. The treated water in the lower tank 47 of the septic tank 44 is sent to the water storage space 8a as purified water and stored. Thus, the purified water stored in the water storage space 8a is returned to the cleaning tank 17a of the toilet 17 by the cleaning pipe 24 and reused as cleaning water.

  In the circulation tray configured as described above, the toilet bowl 17 → the sewage tank 21 → the introduction chamber 9a → the first aerobic processing chamber 11a → the first anaerobic processing chamber 11b → the second aerobic processing chamber 12a → the second anaerobic. Washing water is reused by the circulation of water, such as the treatment chamber 12b → the storage chamber 9b → the purification tank 44 → the purification tank 44 → the purified water space 8a → the toilet 17 →.

  The movement of the sewage from the introduction chamber 9a to the first aerobic treatment chamber 11a and the movement of the sewage from the first anaerobic treatment chamber 11b to the second aerobic treatment chamber 12a are the introduction holes 4a in which the maximum water level is sequentially set lower. The configuration is simplified because no pump or the like is required.

  In addition, the movement of sewage from the first aerobic treatment chamber 11a to the first anaerobic treatment chamber 11b and the movement of sewage from the second aerobic treatment chamber 12a to the second anaerobic treatment chamber 12b are also performed through the communication port 16. Therefore, no power is required and the configuration is simplified.

  Further, in the introduction chamber 9a, the first aerobic processing chamber 11a, and the second aerobic processing chamber 12a, the sewage is smoothly convected along the arcuate inner wall surface formed by the circular cross section of the cylindrical tank 1. The aerobic process is smoothly performed. Moreover, in the introduction chamber 9a, the sewage is convected by the high-pressure blower and the solid matter containing the sewage is pulverized.

  Furthermore, since the smooth flow of sewage is promoted by the arc-shaped bottom surface of the cylindrical tank 1, the accumulation of filth such as sludge on the bottom side of the three treatment tanks 9, 11, and 12 is efficiently prevented. .

  In the above water circulation system, if the degree of purification is low, the sewage can be returned from the storage chamber 9b to the first aerobic treatment chamber 11a. Reduction is also prevented. In addition, the washing tank 17a is highly convenient because the water distribution pipe 26 can also use commercially available water from the water pipe.

  Moreover, since each room can be formed using the surrounding wall of the cylindrical tank 1 and the space can be effectively used, the whole can be formed more compactly.

  Incidentally, in this circulating toilet, the control panel 13 described above automatically controls the drive of the pumps 27, 37, 42, 52, 53 and the blowers 29, 32, 34, etc., and optimally controls the water level and water quality of each part. To do.
