Abstract
Description
technical field
[0001] The invention relates to the field of sewage sludge treatment, in particular to a method for reducing and dehydrating sewage sludge based on electromagnetic force. Background technique
[0002] In the prior art, the most advanced sludge dewatering equipment on the market is the diaphragm plate and frame filter press. During dehydration, the efficiency is low, and the pressing pressure is only 1.6MPa. The high-pressure water pump injects water into the diaphragm plate and frame. , The diaphragm is bulged to reduce the area of the filter chamber, and the diaphragm plate frame is squeezed by the plastic deformation of the plate frame; the compression ratio of the diaphragm plate frame is small, and the relative working cycle is long. In addition, in terms of the structural structure of the common elastic press plate frame on the market, the filter plate is an integral injection molded part, the filter plate is easily damaged and deformed, and the damage...
