METHOD FOR IMPROVING DEWATERING EFFICIENCY OF SLUDGE

摘要

PURPOSE: A method for improving dehydration efficiency of sewage sludge is provided. CONSTITUTION: In a method for improving dehydration efficiency of biological sludge where sludge(10) is mixed with at least one bulking agent(20) selected from sawdust, paper and waste paper to form water passage, the method is characterized in that a mixture of sludge and the bulking agent being mixed in a weight ratio of 100 to 20 is injected to a sludge thickening tank before dewatering.
