摘要：

采用复合引发体系用甲基丙烯酰氧乙基三甲基氯化铵（DMC）和丙烯酰胺（AM）水溶液共聚制备了阳离子高分子絮凝剂P（DMC-AM）。并将其应用于十堰市污水厂废水处理，探讨了其投加量和废水pH对COD_Cr、浊度、色度去除率的影响。结果表明，当处理的废水pH为7.5，P（DMC-AM）投加质量浓度为8mg/L时，废水的COD_Cr去除率达到88%以上，色度和浊度的去除率均达到95%以上。

Abstract:

Using the complex initiation system as polymerization initiator, the copolymer of methylacryloyloxyethyl trimethylammonium chloride(DMC)and acrylamide (AM), P(DMC-AM)is synthesized by aqueous solution polymerization. P(DMC-AM)has been used for the treatment ofwastewater, and the effects of the dosage of P(DMCAM) and the pH of wastewater on the removal rates of COD_Cr, chroma and turbidity of wastewater are studied. The results of the experiments showthat the best conditions of flocculant P(DMC-AM)are: dosage 8mg/L, removal rates of COD_Cr is above 88%, the removal rate of chroma and turbidity are all over 95% when the pH of wastewater is 7.5.

Key words: the complex initiation system, cationic polymeric flocculant, wastewater treatment
