HIGH MOLECULAR FLOCCULATING AGENT AND METHOD OF DEHYDRATING SLUDGE

摘要

PROBLEM TO BE SOLVED: To provide a high molecular flocculating agent having excellent flocculating and dehydrating performance and capable of obtaining low water content cake by adding a little quantity thereof, and to provide a method of dehydrating sludge. SOLUTION: The high molecular flocculating agent is an amphoteric high molecular flocculating agent consisting of an amphoteric high molecular compound and a methacrylate based cationic high molecular compound. The sludge is dehydrated by adding the high molecular flocculating agent after adding or without adding an inorganic flocculating agent.
