Title:
FLOCCULATION TREATMENT AGENT, AND DEWATERING METHOD OF SLUDGE USING THE SAME
Document Type and Number:
Japanese Patent JP2015150534
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To develop a flocculation treatment agent enabling an efficient dehydration treatment by adding the flocculation treatment agent to sludge generated by treatment of sewage, excrement or industrial waste water; and to develop a dewatering method of sludge using the same.SOLUTION: By adding into sludge, a flocculation treatment agent comprising a crosslinked-cationic or crosslinked-amphoteric water-soluble polymer and a primary amino group-containing polymer, an excellent dehydration treatment can be attained, especially when fluctuation of a sludge property is large, or to difficult-to-dehydrate sludge generated by change of a sludge property caused by increase of a sludge organic component or decay of the sludge.
