摘　　要：以有机氯农药废水为研究对象 ,研究了无机混凝剂PAC及其与有机高分子混凝剂PAM (J 3450 ,J 1 1 50 )复合使用的混凝处理特性。通过正交实验确定了混凝反应各种影响因子的最佳操作条件。在此条件下 ,水质 1、2的COD去除率分别为 38%、40 .6 % ;色度去除率分别为 98% ,2 0 %。混凝处理后 2种水质的B/C值也得到了提高。在各影响因子与COD去除率的关系曲线基础上 ,分析了废水中各影响因子的作用机理。This study examined the effects of flocculants PAC, PAM(J-3450, J-1150)and their complex on removal of COD and colority from organochlorine pesticide wastewater. The optimal operating conditions was determined by orthogonal experiments. The removal rate of COD, colourity were 38%, 40.6% and 98%, 20% respectively for sample 1 and sample 2. The value of B/C was improved in the meantime and the mechanisms of affecting factors in wastewater were also analyzed.
