Abstract
A sludge reduction processing system comprises a filter press, a sludge blender, a belt conveyor, and a drying machine. The filter press is arranged above the sludge blender. An outlet of the filter press is connected to an upper sludge-entering opening by arranging a sludge-collecting hopper. A bottom sludge-dumping opening of the sludge blender directly faces the belt conveyor below. A tail end of the belt conveyor is above a sludge-entering opening of the drying machine. Dehydration efficiency is greatly improved, a moisture content of dehydrated sludge is low to about 30%, and a device structure is simple, and industrialized application is facilitated.
