The above-mentioned substances enter the sludge treatment system of waste treatment station, which can damage sludge conveying equipment (such as screw, screw pump, plunger pump, etc.) and subsequent treatment and disposal equipment. Therefore, before sludge treatment, it is necessary to filter and remove impurities from sludge to filter out impurities in sludge, which is convenient for subsequent sludge treatment.

[0004] During the process of filtering and removing impurities, filter plate is usually installed to filter and treat sludge, so that impurities in sludge can be filtered and retained. During the process of filtering, sludge is discharged onto the filter plate through the sludge pipe. The sludge is filtered and treated by weight on the filter plate, so that the filtered impurities are stationary on the filter plate.
