It is. The toilet 2 installed indoors is connected to a septic tank 3 buried outdoors by a pipe 4, and manure from the toilet 2 flows into the septic tank 3 through the pipe 4. Since the septic tank 3 is placed outside the toilet bowl 2 and not outdoors, the capacity of the septic tank 3 is not limited, so that the manure processing capacity is increased and the maintenance and inspection work is also facilitated.

The septic tank 3 is configured such that the top of a septic tank main body 5 that stores microorganisms that decompose manure into wood chips such as cedar, for example, microbial vegetation planted with aerobic high-temperature fermenters is covered with a lid 6.

On the upper part of the septic tank main body 5, a stirring member 9 provided with a stirring screw 7 and a paddle 8 provided below the stirring screw 7 for stirring and mixing the microorganism vegetation and manure contained in the septic tank main body 5. Motor 1 for rotating the
0 is arranged. The rotation of the paddle 8 stirs the microbial vegetation at the lower part of the septic tank main body 5, and the rotation of the stirring screw 7 causes the excrement and the microbial vegetation to move up and down in the septic tank main body 5 to be circulated and agitated. The vegetation and the vegetation are uniformly mixed, and the contact between manure and the microorganism vegetation is promoted, and the microbial decomposition reaction is promoted.

Further, a blower 12 connected to an air supply pipe 11 for blowing air required for propagation of microorganisms contained in the septic tank main body 5 is provided above the septic tank main body 5.

The air supply pipe 11 is provided with a heater 13 for heating the supplied air to generate hot air. The heater 13 can use a well-known electric heating means such as a nichrome wire, and can promote a microbial decomposition reaction by maintaining a temperature at which the microbial vegetation is easily activated by hot air. To maintain the temperature, detect the temperature with a temperature sensor,
This is performed by known means for controlling the power supplied to the heater 13.

An annular heating pipe 14 is connected to a lower portion of the air supply pipe 11 in order to maintain a temperature at which the manure and the microorganisms can easily react. The heating annular pipe 14 is arranged so as to surround the stirring screw 7. The air supplied to the air supply pipe 11 is heated by the heater 13 and flows into the heating annular pipe 14 to heat the microorganism plant by heat transfer.

Further, an air blowing pipe 15 for blowing air required for the microbial vegetation is set up in the heating annular pipe 14, and the air blowing pipe 15 is bent downward in the middle, so that the air blowing pipe at the tip is blown. The entrance 16 is directed downward.

Manure from the toilet bowl 2 in the building 1 falls through the pipe 4 onto the microorganism vegetation housed in the septic tank 3 outdoors.

A stirring member 9 having a stirring screw 7 and a paddle 8 is rotated by a motor 10,
And the rotation of the paddle 8 causes the excrement and the microorganisms to rise and descend in the septic tank main body 5 to circulate and stir uniformly, thereby promoting the contact between the excrement and the microorganisms and the microbial decomposition reaction. As it happens, manure is fermented and broken down into carbon dioxide and water and vaporized. The number of rotations of the stirring member 9 is about 6 times per minute, and the stirring is performed for about 10 minutes every hour, so that the manure and the microorganisms can be uniformly mixed and decomposed.

On the other hand, air is supplied to the air supply pipe 11 by the blower 12, and the air is heated by the heater 13 into the air supply pipe 11 and flows into the annular heating pipe 14.
The heat transfer heats the microbial vegetation and manure.

Further, the heated air flows from the heating annular pipe 14 through the air blowing pipe 15 to the air blowing port 16.
The mixture is blown into the mixture of manure and microbial vegetation to supply necessary oxygen to the microbial vegetation, and is maintained at a temperature of about 50 ° C. at which the mixture promotes the microbial decomposition reaction.
