The groove portion 91 can gather the excrement deposited on the lower layer of the sedimentation bin body 9 near the lower end of the lifting cylinder 10, so that the spiral shaft 11 can drive a large amount of lower layer excrement to spiral upward when it rotates. At this time, the lower layer excrement is solid excrement mixed with a small amount of liquid excrement, which does not affect the overall solid-liquid separation.

The silo 15 is connected to the upper end of the lifting cylinder 10 through a pipeline. The first motor 13 drives the spiral shaft 11 to rotate, driving the lower layer of excrement to spirally rise and then be transported to the silo 15. A stirring shaft 16 is provided in the silo 15. The stirring shaft 16 includes a rotating shaft 161 and a spiral stirring blade 162 provided on the rotating shaft 161.

[0035] Furthermore, if Figure 1 As shown, in this embodiment, a humidity control valve 18 is provided at the upper end of the bin body 15 and a temperature control plate 19 is provided on the side wall.

The sedimentation area 23 of the sewage treatment device 22 is connected to the side wall of the sedimentation bin 9 through a pipeline to receive the upper layer of excrement transported, and to precipitate, filter and purify the upper layer of excrement. At this time, the upper layer of excrement is liquid excrement mixed with a small amount of local excrement; at the same time, the water tank 27 is connected to the clear water area 26 of the sewage treatment device 22 through a pipeline to receive and store the purified grey water. The grey water in the water tank 27 can be recycled for toilet flushing.

[0039] When used specifically, Figure 1 As shown, the mixed excrement in the buffer tank 3 is pumped into the sedimentation bin 9, and the mixed excrement is divided into upper and lower layers in the sedimentation bin 9. The lower layer of excrement is extracted from the lifting cylinder 10 by the spiral shaft 11 and transported to the bin 15 of the biodegradation device 14. The lower layer of excrement is mixed with the microbial agent by the rotation of the stirring shaft 16 in the bin 15. The gas generated after degradation in the bin 15 is filtered and treated by the deodorizing filter device 8 and then discharged; the upper layer of excrement in the sedimentation bin 9 is transported to the sewage treatment device 22 after it is full to a certain liquid level. The upper layer of excrement is precipitated, filtered and purified in the sewage treatment device 22 to become reclaimed water and stored in the water storage tank 27 for subsequent use.
