The following processing is performed based on the command of 0.

First, the three-way switching valve 6 is switch-connected to the waste treatment drainage pipe 8 side to drive the motor 5a of the shredder 5, and at the same time, the electromagnetic valve 11 of the water pipe 10 is opened to start water supply for crushing. The solenoid valve 11 is closed after the amount of water supply or after a certain time. When all of the shredded raw waste and waste treatment wastewater are sent to the solid-liquid separation device 12, the three-way switching valve 6 is switched to the bypass drainage pipe 7 side. As a result, the flow rate of the waste treatment wastewater is regulated to a fixed amount, the load amount of the wastewater treatment device 13 associated with the waste treatment can be stabilized, and the treatment conditions can be made uniform and the device can be made compact.

The raw garbage and the waste treatment wastewater are compressed in the solid-liquid separation device 12 to be crushed raw waste and separated into solid raw waste and wastewater, and the separated wastewater is treated in the wastewater treatment device 13 with microorganisms or Sludge in the wastewater is purified by the chemical substance, and the purified water is discharged from the bypass drain pipe 7 through the solenoid valve 19. The sludge separated in the wastewater treatment device 13 is sent to the solid-liquid separation device 12 to remove water. The solid raw garbage and the excess sludge that have been compressed and separated in the solid-liquid separator 12 are continuously sent to the composting device 16, and the compacted and composted raw garbage is stored in the storage cabinet 15 and as necessary. It is carried out to the outside. Therefore, since the excess sludge separated in the wastewater treatment device 13 is also discharged together with the solid garbage, the maintenance of the wastewater treatment device 13 is greatly reduced.

The odorous gas generated in the wastewater treatment device 13 and the storage 15 is deodorized by the deodorizing device 17 and discharged to the atmosphere. This prevents the odor from adversely affecting the living environment. The temperature inside the treatment unit 3 is maintained at a predetermined value by the temperature sensor 22 and the heater 23, and the activities of the wastewater treatment device 13, the composting device 16 and the deodorizing device 17 are stably maintained.
