ABNORMAL PHENOMENON PREVENTIVE AGENT FOR ACTIVATED SLUDGE AND METHOD FOR PREVENTING ABNORMAL PHENOMENON OF ACTIVATED SLUDGE

摘要

PURPOSE:To exterminate the actinomycetes to be the cause for bulking, etc., by using the reaction product of amine and diepoxide or the amine and the diepoxide and epihalohydrin, etc. CONSTITUTION:The amine and the diepoxide or the amine and the diepoxide and the epihalohydrin and/or alkylene dihalide are brought into reaction to synthesize the water soluble polymer. This water soluble polymer is added to the activated sludge contg. the filamentaous bacteria or actinomycetes or the waste water contg. the activated sludge at 0.05 to 25 pts.wt. per 100 pts.wt. dry solid content of the activated sludge, by which the abnormal phenomenon of the activated sludge is prevented. The ultimate viscosity [eta] of the above mentioned water soluble polymer is adequately 0.02 to 0.4dl/g (25 deg.C).
