[0028] The power box 5 is fixedly connected to the inner surface of the mounting bracket 401, and the auger 501 is rotatably connected to the outer surface of the power box 5.

[0029] Specifically, during use, wastewater is discharged into the treatment tank 1, and the sludge is removed after being filtered by the filter screen 6.

[0030] The treatment tank 1 can be tilted by adjusting the tilting module 2, so that the sewage can move along the filter screen 6, thereby improving the sludge removal effect of the sewage. There is a height difference between the first sliding seat 202 and the second sliding seat 209. The dual-axis motor 211 provides power for the adjustment of the tilting module 2.

[0031] The first support plate 3 supports the filter screen 6.
