  The filth washed in the toilet 2 is stored in the raw water tank 3 and sent to the receiving tank 4 by a pump. In the receiving tank 4, air is introduced into the tank by the aeration process of the blower 10 to increase dissolved oxygen, reduce the load of the biological treatment in the next stage, and finely divide the filth by the pressure of the aeration process. The processing object processed in the receiving tank 4 is sent to the biological treatment tank 5 by natural flow. In the biological treatment tank 5, an aerobic treatment with an aerobic bacterium and an anaerobic treatment with an anaerobic bacterium are alternately performed.

The partition walls 51c and 52c are curved downward in the direction of the aerobic treatment regions 51a and 52a (left direction in FIG. 2), and the air supplied upward from the curved tip is separated from the partition walls 51c and 52c. The aerobic treatment areas 51a and 52a are circulated along the curve 52c (the air flow is indicated by an arrow a in FIG. 2), and contact aeration is efficiently performed.

  Further, by curving the partition walls 51c and 52c in the direction of the aerobic treatment region 51a, the influence on the anaerobic treatment regions 51b and 52b due to air circulation and liquid circulation in the aerobic treatment regions 51a and 52a is minimized. ing. In other words, the aerobic treatment and the anaerobic treatment can be performed efficiently without adversely affecting each other while being performed in the same tank. Further, since the aerobic treatment region 51a and the anaerobic treatment region 51b and the aerobic treatment region 52a and the anaerobic treatment region 52b communicate with the same space, the anaerobic treatment regions 51b and 52b that tend to be low in temperature are aerobic. It is possible to maintain the same temperature as the processing regions 51a and 52a, and to perform the anaerobic processing more efficiently.

  When the aerobic treatment and the anaerobic treatment are repeated a plurality of times, as shown in FIG. 2, the first side wall 11 has a structure having a first biological treatment tank 11 and a second biological treatment tank 12 having the same functions. 13 height h1> second side wall 14 height h2> third side wall 15 height h3, the upper end of the partition wall 51c is higher than the upper end of the first side wall 13, and the partition wall 52c The entire biological treatment tank 5 is formed so that the upper end portion is positioned above the upper end portion of the second side wall 14. After the treatment in the first biological treatment tank 11, the object to be treated is sent out to the second biological treatment tank 12 under natural flow, and the aerobic treatment and the anaerobic treatment are repeated a plurality of times (in the case of FIG. 2 twice). It becomes possible. The processing object processed in the 2nd biological treatment tank 12 is sent to the process part of the next stage under natural flow.

  The number of repetitions of the aerobic process and the anaerobic process is arbitrarily determined according to the location and the size of the entire biotoilet system. That is, it may be performed once (a configuration including only the first biological treatment tank 11), or may be repeated a plurality of times (a configuration including the first biological treatment tank 11 to the nth biological treatment tank). .

  Returning to FIG. 1, when the biological treatment is performed in the biological treatment tank 5, the remaining processing object is sent out to the sedimentation tank 6. In the sedimentation tank 6, the solid filth that could not be treated in the biological treatment tank 5 is settled, and only the supernatant liquid is sent out to the next processing section. The sedimentation tank 6 will be described in detail below.

  FIG. 3 is a diagram showing a first structure of a sedimentation tank in the biotoilet system according to the present embodiment. The sedimentation tank 6 includes first sedimentation areas 21a and 22a into which the processing object remaining in the biological treatment tank 5 flows, and second sedimentation areas 21b and 22b in which the supernatant liquid of the processing object is mainly stored. The first sedimentation area 21a and the second sedimentation area 21b, and the sedimentation tank partition walls 21c and 22c that divide the first sedimentation area 22a and the second sedimentation area 22b in a state where they communicate with each other below the tank. Guiding plates 21d and 22d for pouring the processing object below the sedimentation tank partition walls 21c and 22c are provided at positions where the processing object flows down in the first sedimentation regions 21a and 22a. The guide plates 21d and 22d can be installed at an arbitrary angle, but the angle with the bottom surface of the settling tank 6 is preferably about θ = 63 °. The solid material contained in the object to be treated flows into the second sedimentation regions 21b and 22b along the guide plates 21d and 22d, and settles and accumulates on the bottom surface in the tank. That is, the solid matter in the processing object is deposited on the bottom surface in the tank, and the supernatant liquid is sent out to the processing unit at the next stage.

  The solid matter deposited on the bottom surface in the tank is transferred to the raw water tank 3 by the pump 23 disposed on the bottom surface in the tank, and the processing so far is performed again. That is, the solid matter remaining in the sedimentation tank 6 is subjected to aeration treatment and biological treatment again through the receiving tank 4, the biological treatment tank 5 and the sedimentation tank 6, so that there is almost no residue and is regularly Maintenance such as disposal of sludge is no longer necessary.

  When the sedimentation process is repeated a plurality of times, as shown in FIG. 3, the first sedimentation tank 25 and the second sedimentation tank 26 having the same functions are provided, and the height of the first side wall 27 is set. H1> height H2 of the second side wall 28, the upper end of the settling tank partition 21c is above the upper end of the first side wall 27, and the upper end of the settling tank partition 22c is the upper end of the second side wall 28. The entire sedimentation tank 6 is formed so as to be positioned above the part. After the treatment in the first sedimentation tank 25, the supernatant liquid is sent out to the second sedimentation tank 26 under natural flow, and the sedimentation process can be repeated a plurality of times (in the case of FIG. 3 twice). The supernatant liquid stored in the second sedimentation tank 26 is sent to the next processing section by the pump 24.

  FIG. 4 is a view showing a second structure of the sedimentation tank in the biotoilet system according to the present embodiment. In FIG. 4, the sedimentation tank 6 is formed in a tubular shape, and the object to be treated flows into the second flow pipes 41b and 42b from the first flow pipes 41a and 42a. Below the merging positions 41c and 42c where the first circulation pipe 41a and the second circulation pipe 41b, and the first circulation pipe 42a and the second circulation pipe 42b merge, are used for sedimenting and depositing solid matter. Deposition regions 41d and 42d are provided. Further, above the joining positions 41c and 42c, there are provided reduction areas 41e and 42e for reducing the cross-sectional areas of the second inflow pipes 41b and 42b. The supernatant liquid that has passed through the reduced regions 41e and 42e is sent to the processing unit of the next stage by the pump 43. The solid matter contained in the processing object is settled in the deposition regions 41d and 42d and is less likely to flow above the reduced regions 41e and 42e, so that the solid matter can be deposited efficiently. Note that the reduced areas 41e and 42e may have a configuration in which the cross-sectional area of the pipe is narrowed in advance, or may be configured so that the cross-sectional area can be arbitrarily set by a piston or the like, for example.

  Below the accumulation areas 41d and 42d, a pump 44 for transferring the solid matter accumulated in the accumulation areas 41d and 42d to the raw water tank 3 is provided, and is deposited in the same manner as described above with reference to FIG. The solid matter is again subjected to aeration treatment and biological treatment through the receiving tank 4, the biological treatment tank 5 and the sedimentation tank 6, so that almost no residue remains, and maintenance such as periodic disposal of sludge is not necessary.

  When the sedimentation process is repeated a plurality of times, as shown in FIG. 4, the first sedimentation tank 45 and the second sedimentation tank 46 having similar functions are connected, and the supernatant liquid of the first sedimentation tank 45 is The second settling tank 46 is sent out to the first flow pipe 42a. The same sedimentation process is performed in the second sedimentation tank 46, and the supernatant liquid is sent out to the next processing section (in FIG. 4, two sedimentation processes are performed). At this time, the entire settling tank 6 is formed so that the upper pipe of the first flow pipe 41 a of the first settling tank 45 is positioned above the upper pipe of the first flow pipe 42 a of the second settling tank 46. The supernatant liquid that has flowed through the second sedimentation tank 46 is sent to the next processing section by the pump 43.

  Returning to FIG. 1, when the sedimentation process is performed in the sedimentation tank 6 having the structure shown in FIG. 3 or FIG. 4, the remaining solid matter is returned to the raw water tank 3 as described above and finally all decomposed, Only the supernatant is sent to the reaction vessel 7 by a pump. In the reaction tank 7, the organic matter contained in the supernatant liquid (= organic liquid) of the sedimentation tank 6 is decomposed by bacteria and purified to a level that can be reused as washing water. The reaction tank 7 will be described in detail below.

  FIG. 5 is a diagram showing the structure of the reaction tank in the biotoilet system according to this embodiment. The reaction tank 7 is filled with spraying units 71a and 72a that spray the supernatant liquid pumped up from the settling tank 6, and biochips on which bacteria that decompose organic substances contained in the sprayed supernatant liquid are implanted. Decomposition regions 71b and 72b. This biochip has an enormous surface area and porosity, and the organic substance contained in the liquid is removed by spraying the supernatant liquid. The liquid from which the organic matter has been removed is purified to a level where it can be reused as washing water, drained by pumps 71c and 72c installed below the tank, and sent to the next processing section.

  In order to further increase the cleaning level, the treatment in the reaction vessel may be repeated a plurality of times (in the case of FIG. 5 twice) as shown in FIG. In that case, the purified water obtained in the first reaction tank 73 is pumped up and sprayed again in the second reaction tank 74 as shown in FIG.

  Returning to FIG. 1, the wash water obtained in the reaction tank 7 is stored in the wash water tank 8 and reused as the wash water for the toilet 2.

  As mentioned above, the filth washed with the toilet 2 is decomposed | disassembled by passing through each processing tank, and water can be reused as washing water. In addition, solid matter such as chips is decomposed by biological treatment together with the filth, so that no extra sludge is generated, and it is not necessary to periodically remove the sludge for maintenance or the like.

  Next, a waste disposal method using the biotoilet system according to the present embodiment will be described. FIG. 6 is a flowchart of the waste disposal method using the biotoilet system according to the present embodiment. When the operation of the biotoilet system 1 is started and the toilet 2 is used, the filth is washed (S1). The washed filth is subjected to aeration treatment, and dissolved oxygen is increased to reduce the load of the next biological treatment, and the filth is finely divided by the pressure of aeration (S2). The aerobic process (S3) and the anaerobic process (S4) are repeated one or more times on the processing target that has been subjected to the aeration process.

  When the biological treatment of S3 and S4 is performed, a sedimentation treatment for separating the remaining solid and liquid is performed (S5). The sludge settled by the sedimentation process is returned to S2, and the process up to S5 is repeated again. The supernatant liquid from the sedimentation process is stored intermediately (S6), and the organic matter in the liquid is decomposed by the bacteria and then regenerated as washing water (S7). The regenerated wash water is reused again as toilet wash water.

  Thus, in the waste disposal method using the biotoilet system according to the present embodiment, the biological treatment is repeatedly performed until the sludge remaining as solid matter is completely decomposed. It is possible to eliminate troublesome work such as removing.
