  Referring to FIG. 1, the basic configuration of an entire excrement disposal apparatus according to an embodiment of the present invention will be described. A first treatment tank 2 that receives excrement from a toilet 1 together with cleaning water, and a higher position than the first treatment tank 2. And a final processing tank 4 disposed at a lower position than the second processing tank 3. The first processing tank 2 and the second processing tank 3 include A feed line 6 including a pump 5 that feeds the liquid processing product stored in the processing tank 2 into the second processing tank 3, and a liquid processing product stored in the second processing tank 3 in the first processing. Connected by an overflow line 7 that returns to the tank 2 by overflow. The overflow line 7 is closed automatically when the stored liquid processing product in the first processing tank 2 exceeds the set water level L1. Is provided in the second processing tank 3 The final processing tank 4 is a storage in the second processing tank 3 when the water level of the stored liquid processing product in the second processing tank 3 exceeds a set water level L3 higher than the overflow water level L2 to the overflow pipe 7. It is connected by a siphon conduit 9 that causes the liquid treatment product to flow out into the final treatment tank 4 by siphon action. The final treatment tank 4 is opened and closed to take out the liquid treatment product that has been subjected to final treatment stored in the final treatment tank 4. A free discharge port 10 is provided.

  The automatic opening / closing means 8 is composed of a float 8a that moves up and down as the water level of the liquid treatment product in the first treatment tank 2 changes, and an opening and closing valve 8b that opens and closes in conjunction with the up and down movement of the float 8a. Yes. The first treatment tank 2 is provided with a water level sensor 11 for detecting that the water level of the stored liquid treatment product has reached the abnormally high water level L4, and the stoppage of the use of the toilet 1 is indicated by the detection signal of the water level sensor 11. The emergency lights are turned on automatically.

  The inside of the second processing tank 3 is divided into two by a partition plate 12 into a first tank 3A in which a feed pipe 6 opens at the bottom and a second tank 3B in which an overflow pipe 7 and a siphon pipe 9 are provided. Has been. And this 1st tank 3A and 2nd tank 3B are the upper part in 1st tank 3A, specifically, the upper end opening water level of the overflow pipe line 7, ie, substantially the same height as the overflow water level L2, and 2nd tank 3B. It connects with the communication pipeline 13 which connects the inside bottom part. The communication pipe 13 is provided with an opening 13a provided at substantially the same height as the overflow water level L2 of the partition plate 12, and an upper end block attached to the partition plate 12 so as to cover the second tank 3B side of the opening 13a. Thus, only the lower end is formed by a groove member 13c that forms an opening 13b opened in the second tank 3B. The siphon conduit 9 is connected to the suction side vertical conduit 9a opening at the bottom in the second tank 3B, and the upper end of the suction side vertical conduit 9a via the U-turn portion at the height of the set water level L3. The discharge side vertical pipe line 9b is opened at the upper part in the final processing tank 4. Therefore, the siphon conduit 9 can be configured by bending one tube body.

  In the final treatment tank 4, an ozone generation pipe 14 is provided near the bottom, and it is detected that the water level of the liquid treatment product in the final treatment tank 4 has reached a set water level L 5 that is slightly higher than the ozone generation pipe 14. A water level sensor 15 is provided. The ozone generation pipe 14 is energized when the water level sensor 15 detects the liquid processing product in the final processing tank 4, that is, when the water level of the liquid processing product in the final processing tank 4 is not lower than the set water level L5. Automatically controlled to generate ozone.

  The operation of the basic configuration shown in FIG. 1 will be described. In a state where the toilet 1 can actually be used, water to which decomposition promoting bacteria are added is stored in the first processing tank 2 and the second processing tank 3. And the pump 5 is operated, and the liquid processed product (decomposition promoting bacteria added water) in the first processing tank 2 is sent into the first tank 3A of the second processing tank 3 from the feeding line 6; It flows into the 2nd tank 3B of the 2nd processing tank 3 via the communicating pipe line 13 from this 1st tank 3A, and overflows from the overflow pipe line 7 so that it may return in the original 1st processing tank 2 It is circulating and flowing. At this time, the level of the liquid processed product (degradation promoting bacteria added water) in the first processing tank 2 is lower than the set water level L1, and the level of the liquid processed product (degradation promoting bacteria added water) in the second processing tank 3 is The overflow water level L2. In this state, the toilet 1 is used, and after use, although not shown in the drawing, feces and urine are discharged into the first treatment tank 2 together with the wash water supplied to the toilet 1. In addition, the discharge port 1a of the toilet 1 can be provided with a well-known automatic opening / closing lid that automatically opens when the washing water flows out.

  As described above, the liquid processing product containing manure discharged in the first processing tank 2 circulates and flows in the first processing tank 2 and the first tank 3A and the second tank 3B of the second processing tank 3 in this order. The flow of the liquid processing product in the second processing tank 3 at this time rises from the bottom of the first tank 3A, and from the top of the first tank 3A to the bottom of the second tank 3B. Then, the liquid tank rises from the bottom of the second tank 3B and flows out from the upper part of the second tank 3B to the overflow pipe 7, so that the liquid processing product does not stay in the second processing tank 3. Thus, as the number of times the toilet 1 is used increases, the water level of the liquid processing product in the first processing tank 2 rises, and the water level of the liquid processing product in the first processing tank 2 reaches the set water level L1. Then, the float 8 of the automatic opening / closing means 8 that moves upward as the water level of the liquid treatment product rises closes the on-off valve 8b, and thereafter, the overflow pipe from the second tank 3B of the second treatment tank 3 The overflow of the liquid processed product returning to the first processing tank 2 via 7 stops.

  Even if the overflow of the liquid processing product from the second processing tank 3 into the first processing tank 2 stops, the pump 5 continues to operate, and the liquid processing product in the first processing tank 2 passes through the feed line 6. Since it is sent into the first tank 3A of the second treatment tank 3 via the water level, the liquid level of the liquid treatment product in the second treatment tank 3 rises from the overflow water level L2, and as a result, the liquid level in the second treatment tank 3 is increased. The water level of the processed product reaches the set water level L3. When the water level of the liquid processing product reaches the set water level L3, the liquid processing product pumped up from the inside of the first processing tank 2 thereafter is discharged from the upper end of the suction side vertical pipe 9a of the siphon pipe 9 to the discharge side vertical pipe. The siphon action flows out into the passage 9b, and a siphon action is generated in the siphon duct 9 as the liquid process material flows down in the discharge-side vertical duct 9b due to gravity. Thereafter, the second treatment is performed by the siphon action. The liquid processed material in the tank 3 is automatically discharged into the final processing tank 4 via the siphon conduit 9. Here, the flow rate per unit time of the liquid processed material automatically discharged into the final processing tank 4 via the siphon line 9 is supplied from the supply line 6 to the second processing tank 3 by the pump 5. It is comprised so that it may become larger than the flow volume per unit time.

  Therefore, even if the pump 5 is continuously operated and the inflow of the liquid processed material from the first tank 3A to the second tank 3B through the communication conduit 13 is continued, the second tank 3B is caused by siphon action. As the liquid processed product in the tank is discharged into the final processing tank 4, the water level of the liquid processed product in the second tank 3B is lowered, and the water level of the liquid processed product in the second tank 3B is the siphon conduit. When the suction side vertical pipe line 9a is opened lower than the lower end opening of the suction side vertical pipe line 9a, the liquid processed material is discharged to the final treatment tank 4 via the siphon line 9. finish.

  That is, until the water level of the liquid processing product in the first processing tank 2 reaches the set water level L1, the liquid processing product continues to circulate and flow in the first processing tank 2 and the second processing tank 3, during which After the decomposition of the processed product is performed and the water level of the liquid processed product in the first processing tank 2 reaches the set water level L1, the decomposed liquid processed product in the second tank 3B of the second processing tank 3 is removed. It is automatically transferred into the final processing tank 4. And since the supply of the liquid processing material from the 1st processing tank 2 to the 2nd processing tank 3 by the pump 5 continues, the water level of the liquid processing material in the 1st processing tank 2 will be below the setting water level L1. As a result of the inflow of the liquid processed material from the first tank 3A to the second tank 3B via the communication conduit 13 of the second processing tank 3, the water level of the liquid processed material in the second processing tank 3 is reduced. When it becomes higher than the overflow water level L2, it returns to the original state in which the liquid treatment product circulates and flows through the first treatment tank 2 and the second treatment tank 3 again. If the toilet 1 is used frequently and the water level of the liquid treatment product in the first treatment tank 2 continues to rise without dropping below the set water level L1, the water level of the liquid treatment product in the first treatment tank 2 Reaches the abnormally high water level L4 detected by the water level sensor 11, and the lighting of the emergency light indicating the stop of use of the toilet 1 is automatically executed.

  On the other hand, the amount of the liquid treatment product discharged from the second treatment tank 3 to the final treatment tank 4 by the siphon action by the siphon conduit 9 is the overflow water level L2 so that the optimum treatment capacity in the final treatment tank 4 is obtained. The water level difference from the set water level L3 at which the siphon action is started, the capacity of the second tank 3B of the second treatment tank 3, the lower end opening water level in the suction side vertical pipe 9a of the siphon pipe 9, etc. are set. ing. Thus, when the liquid treatment product flows into the final treatment tank 4, when the water level of the liquid treatment product in the final treatment tank 4 reaches the set water level L 5, that is, the ozone generation pipe 14 is in the liquid treatment product. The water level sensor 15 is activated at the time of burying, the ozone generating pipe 14 is energized, and the ozone treatment, that is, the sterilization / deodorization treatment, is performed on the liquid treatment product transferred into the final treatment tank 4. The time for the sterilization / deodorization treatment by the ozone generation tube 14 is controlled by a timer, and when the elapsed time after the ozone generation tube 14 is energized reaches the set time, the energization to the ozone generation tube 14 is cut off, An automatic lighting of an indicator lamp that prompts removal of the processed liquid material from the final processing tank 4 is performed. Therefore, the administrator or the like can open the discharge port 10 of the final processing tank 4 and transfer the processed liquid material discharged from the discharge port 10 to a container or the like and process it accordingly. Of course, depending on the properties of the processed liquid material taken out from the final processing tank 4, the processed liquid material may be directly discharged from the discharge port 10 into the soil, the rainwater treatment pipe, or the like.

  The second treatment tank 3 is not limited to a two-tank structure, and may be a multi-tank structure having three or more tanks, or a one-tank structure. When the second treatment tank 3 has a plurality of tank structures, the opening position of the supply pipeline 6 with respect to the second treatment tank 3 (first tank 3A) is not the bottom but the tank top, and conversely, the communication pipe between the tanks The path 13 may be structured to open from the bottom in the upper tank to the upper part in the lower tank.

A letter-shaped second treatment tank 3 and a washing water tank 26 having a rectangular shape in plan view on the rear side of the vertical partition plate 22c are formed. The partition plate 12 having the communication pipe line 13 of the second processing tank 3 is vertically stretched on the horizontal partition plate 22a between the vertical partition plate 22c and the front side wall portion of the upper vertical tank structure 22. ing. The upper end of the second treatment tank 3 and the washing water tank 26 arranged in parallel in the front and back can be opened and closed by a common removable lid 27, and the lid 27 can be opened and closed at a position directly above the washing water tank 26. A water supply port provided with a cap 26a is provided. Further, on the rear side wall portion of the upper vertical tank structure 22, a transparent window 26b for confirming the water level elongated in the vertical direction for visually checking the amount of water in the washing water tank 26 is provided.

  The feed line 6 that connects the first processing tank 2 and the first tank 3A of the second processing tank 3 is provided on the vertical partition plate 21b of the lower horizontal tank structure 21, as shown in FIG. A horizontal tube 6a that connects the opening and the suction port of the pump 5 and, as shown in FIG. 6, penetrates the final processing tank 4 with the upper end fixed to the horizontal partition plate 22a of the upper vertical tank structure 22. In addition, a vertical tube body 6b whose lower end portion passes through the bottom plate portion 22b of the upper vertical tank structure 22 downward, and a connecting tube body 6c that connects the lower end portion of the vertical tube body 6b and the discharge port of the pump 5 It is configured. Since the connection pipe body 6c is disposed in the container storage space 25, the connection pipe body 6c is disposed at a height that does not interfere with the container 24 that is taken in and out of the container storage space 25. Further, as shown in FIG. 4, the first processing tank 2 surrounds the inner corner portion of the vertical partition plate 21b of the lower horizontal tank structure 21 in which the horizontal pipe body 6a of the feed pipe 6 opens. A filter net 28 is stretched in a circular arc shape in plan view.

  As shown in FIGS. 5 and 7, the overflow pipe 7 is a vertical pipe that passes through the bottom plate portion 22 b and the horizontal partition plate 22 a of the upper vertical tank structure 22 and opens at the overflow water level L <b> 2 in the second processing tank 3. Body 7a, a horizontal tube 7b that horizontally penetrates the vertical partition plate 21b of the lower horizontal tank structure 21, and a connecting tube 7c that connects the lower end of the vertical tube 7a and the horizontal tube 7b. ing. As shown in FIGS. 4 and 5B, the float 8a of the automatic opening / closing means 8 for opening and closing the overflow pipe 7 is fixed to the first treatment tank 2 side of the vertical partition plate 21b of the lower horizontal tank structure 21. An opening / closing valve 8b that is supported by a swing arm 31 that is supported on a bearing plate 29 provided so as to swing up and down around a horizontal support shaft 30 via a support rod 32, and that is linked to the float 8a.

The arcuate open end 7d is closed. When the arc-shaped valve plate 33 closes the arc-shaped opening end 7d of the horizontal pipe body 7b, there is a gap between the two, and the liquid processing product is discharged from the overflow pipe 7 into the first processing tank 2. Even if it flows in, if it is configured so that the amount thereof is small, the intended effect is not affected. When the arc-shaped valve plate 33A closes the arc-shaped opening end 7d of the horizontal tube 7b, the float 8a contacts the upper side wall of the first processing tank 2, that is, the lower side of the cover plate 2c. Further upward swing is prevented, so that the arc-shaped valve plate 33 passes below the open end of the horizontal tube 7b and the open end of the horizontal tube 7b opens again. Although not provided, another stopper may be provided to prevent the arc-shaped valve plate 33 from swinging downward from the position where the arc-shaped opening end 7d of the horizontal tube 7b is closed.

  FIG. 5C shows a modification of the on-off valve 8 b of the automatic opening / closing means 8.

Is configured to overlap with the inclined opening end 7e of the horizontal tubular body 7b from above. According to this configuration, not only the end of the horizontal tube body 7b on the first processing tank 2 side and the valve body can be easily processed, but also the inclined opening of the horizontal tube body 7b is utilized by utilizing the buoyancy acting on the float 8a. The end 7e can be reliably closed with the flat plate-like valve plate 33B. Further, it is not necessary to provide a stopper for limiting the upward movement of the float 8a. As shown in the figure, the flat plate-shaped valve plate 33B is not fixed to the swing arm 31 at a predetermined angle, but is pivotally supported around the horizontal support shaft 31a so that the horizontal tube 7b is supported. It is desirable that the flat plate-like valve plate 33B be securely attached to the inclined opening end 7e.
