[0015] Compared with the prior art, the utility model has at least one of the following beneficial effects:

[0016] The utility model is provided with a sedimentation tank, and a sludge hopper is provided at the bottom of the sedimentation tank, and a plurality of stripping water pipes with different distances from the bottom of the sludge hopper are provided, and the stripping water pipes and sludge discharge pipes are vertically or obliquely arranged. Due to the different sizes and concentrations of sludge particles, stripping water pipes at different heights and angles and sludge discharge pipes at different angles are arranged, so that sludge can be discharged better and the sludge discharge efficiency can be increased.

[0017] An air outlet plate is arranged at the end of the air inlet pipe, and the air outlet plate is arranged at the bottom of the sludge hopper, which can make the air intake more uniform and increase the sludge discharge effect.

[0018] The walls of the sedimentation tank are equipped with splash-proof rings to prevent sewage and sludge from splashing out. BRIEF DESCRIPTION OF THE DRAWINGS
