The current disc filter has a single negative pressure vacuum as the power for the imbibition operation in one filtering period, and has a limit of one atmosphere and limited power, so that the thickness of a filter cake on the surface of a filter cloth in an imbibition area is limited from the power source, thereby limiting the efficiency of the filtering rate of the filter, namely the processing capacity of the filter. Similarly, when the filter is carried out by vacuumizing under negative pressure, the thickness of the filter cloth adsorption material layer is completely realized by the power of vacuumizing, the energy consumption of the unit treatment capacity of the filter is higher, and the filtering treatment capacity is low.
