Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a sewage purification tank attached to a flush toilet.

[0002]

[Prior art]

 The water that passed through the sewage treatment tanks installed in each house was discarded as is, and the sludge accumulated in the sewage tanks was regularly removed and cleaned, but none of them could be used as fertilizer.

[0003]

[Problems to be solved by the device]

 In the decontamination type toilet, it is possible to supply the manure by installing a jar. The idea is to obtain good quality manure from the septic tank of the flush toilet.

[0004]

[Means for Solving the Problems]

 A description will be given with reference to the drawings. The sewage purification tank with a liquid fertilizer extracting device according to the present invention is a sewage purification tank 10 including an anaerobic filter bed tank 11, a contact aeration tank 12, a sedimentation tank 13 and a disinfection tank 14 from a waste water inflow pipe J to a drain pipe K. A cylindrical aerobic culture tank 20 is arranged near the anaerobic filtration tank, and the anaerobic filtration tank extends from the inlet 31 near the floor bottom 15 of the anaerobic filtration tank 11 to near the liquid level L of the septic tank 10 and then extends in the lateral direction. A suction passage 30 that penetrates 11 to reach the outlet 32 in the culture tank 20 is provided, and an air pipe 33 for the air lift pump 35 is connected near the inlet 31 of the suction passage 30 so that the liquid is placed on the bottom floor 21 of the culture tank 20. A pump 23 for pumping the fertilizer extraction pipe 22 and a porous expelling pipe 25 communicating with an air pipe 24 are provided, and a microbial culture injection port 28 is provided at a position higher than an outlet 32 in the culture tank 20. It is covered with the lid 26.

[0005]

[Action]

 When the valve 34 is opened, the air lift pump 35 operates and the liquid in the lower part of the anaerobic filter bed tank 11 is sent to the culture tank 20 through the suction passage 30. Since the liquid is fed by the air lift pump 35, the liquid level L of the liquid in the culture tank 20 rises only up to a certain height. When the valve 34 is closed, the valve 27 is opened, and air is constantly ejected from the porous insufflation tube 25 to agitate the liquid, an appropriate amount of microbial culture is injected from the microbial culture injection port 28, whereby aerobic digestive liquid fertilizer can be produced. The pump 23 is turned to take out the liquid fertilizer from the liquid fertilizer taking-out pipe 22.

[0006]

【Example】

 The sewage purification tank 10 is provided with an anaerobic filter bed tank 11, a contact aeration tank 12, a settling tank 13 and a disinfection tank 14 from the sewage inflow pipe J toward the drain pipe K.

A cylindrical aerobic culture tank 20 having substantially the same height as that of the septic tank 10 is arranged near the wastewater septic tank 10. A suction passage 30 that rises from an inlet 31 near the floor bottom 15 of the anaerobic filtration tank 11 to a position near the liquid level L of the septic tank 10 and then extends laterally to penetrate the anaerobic filtration tank 11 and reach an outlet 32 in the culture tank 20. Is provided. An air pipe 31 for the air lift pump 35 is connected near the inlet 31 of the suction passage 30. A valve 34 connects and disconnects the compressed air of the air pipe 31. On the bottom floor 21 of the culture tank 20, a pump 23 for pumping a liquid fertilizer take-out pipe 22 and a porous blower pipe 25 communicating with an air pipe 24 are provided. A microbial culture bacterium injection port 28 is provided at a position higher than the outlet 32 in the culture tank 20, and the culture tank 20 is covered with a manhole cover 26. Reference numeral 37 is a valve for connecting and disconnecting compressed air to and from the air pipe 24.

[0008]

[Effect of device]

 It is disadvantageous to directly apply the sewage liquid in the anaerobic filter bed tank 11 to the plants. Outside the septic tank 10, a microbial culture bacterium injection port 28 is provided along with the aerobic culture tank 20, and is injected, and the liquid in the aerobic culture tank 20 is stirred by the air sent from the air pipe 24 to sufficiently react, It is now used as an aerial liquid fertilizer. It is effective for home use with plants, can be used as an organic liquid fertilizer, and can be easily used by using a pump hose. Moreover, the sludge treatment amount is significantly reduced, which contributes significantly to recycling.
