摘要
向聚丙烯酰胺(PAM)中加入N aOH使其水解来制备阴离子型聚丙烯酰胺(HPAM),并与在酸性介质中带正电荷的壳聚糖复配,混凝处理钻井废水。设计正交实验对HPAM和壳聚糖加量,PAM水解时间,水解pH值进行评价,并与其他混凝剂进行对比,取得了污水混凝处理和脱色效果好,CODcr去除率较高的实验结果。
A series of Hydrolyzed Polyacrylamide （HPAM） can be prepared by adding NaOH to the Polyacrylamide（PAM）. And we use the HPAM in combination with Chitosan which has many positive charges in the acid solution as coagulant to treat drilling wastewater. We have designed a perpendicular experiment to investigate the amount of HPAM and Chitosan used in treating the drilling wastewater, and we get good results in coagulating and decreasing CODcr, especially in discoloring.
