Rotary disc filter sludge treatment device

The utility model provides a rotary disc filter sludge treatment device which comprises a filter, a sludge treatment box is arranged below the filter, a hollow water shaft is rotatably mounted in the filter, a plurality of rotary filter discs are equidistantly mounted on the outer side of the hollow water shaft, and a backwashing mechanism is arranged on each rotary filter disc. The backwashing mechanism is connected with the sludge discharge pipes, all the sludge discharge pipes are communicated with the sludge conveying pipe, and the outlet of the sludge conveying pipe is arranged at the inlet of the sludge treatment mechanism. Sludge which is easy to block flows in the sludge inlet hopper through the stirring mechanism, then the sludge enters the auger assembly and is discharged through the sludge outlet, the sludge can be stably sent out, the uniformity of the sludge is kept, the problems of blockage and leakage of the sludge in the conveying process can be avoided, and the sludge conveying efficiency is
