Abstract：
 The present invention relates to supersonic mud dewatering method and belongs to the field of solid waste treating technology. The supersonic mud dewatering method includes: the first treatment of dewatered mud from sewage treating yard in a stirrer and a press to form cake, treating in a supersonic treating unit, further dewatering in a dewatering unit to obtain dewatered mud as resource, and draining the separated water back to sewage treating yard. The treated mud has water content lowered from 80-85 % to 60-70 % and is suitable for use as resource. Compared with available technology, the present invention has low power consumption, low cost and excellent application foreground.
