For example, in the embodiment shown in fig. 1, the liquid inlet end is provided at the top of the spiral shell stacking machine 10, and wastewater can be fed into the machine cabin of the spiral shell stacking machine 10 through the liquid inlet end. The machine cabin of the spiral shell stacking machine 10 is obliquely arranged from left to right, the liquid outlet end is arranged at the left side of the machine cabin, the mud outlet end is arranged at the right side of the machine cabin, the separated liquid can actively flow leftwards under the influence of dead weight and finally flow out of the liquid outlet end to enter the sedimentation zone 20a, and the extruded mud can move rightwards under the pushing of the screw shaft and finally be discharged from the mud outlet end.
Optionally, the wastewater treatment mechanism further comprises a waste bin, wherein the waste bin is communicated with the sludge outlet end and is used for collecting discharged sludge.
Because the spiral shell machine 10 is installed on the support, and is arranged in a lifting manner compared with the ground, the waste bin can be directly arranged under the mud outlet end so as to receive the naturally dropped mud.
