Preferably, broach hopper side wall is provided with some vibrators, and vibrator accelerates the aggregation to sludge, facilitates sludge
Discharged by sewage draining exit, the efficiency high that sludge is reclaimed.
Compared with prior art beneficial effect shows the utility model：
If 1) swash plate box house is provided with dried layer swash plate, equidistantly distributed between swash plate and swash plate is carried out effectively to sewage
Precipitation, shorten the sedimentation cycle of sewage, sedimentation effect is good；
2) swash plate wall box is provided with some backwash entrances, and backwash entrance connects high pressure back-flushing by pipeline, tiltedly
Sludge on plate is backwashed, it is to avoid sludge excessive deposition, causes to block swash plate, affects settlement of sewage stable operation；
3) support column is provided with top canister and bottom casing realizes and sewage is effectively staticly settled, in certain sky
Secondary precipitation of the interior realization to sewage, shortens the sedimentation cycle of sewage, and sedimentation effect is good.
