摘　　要：介绍了高浊度水混凝沉淀时HPAM(水解聚丙烯酰胺 )一次投加、HPAM分步投加、PAC +HPAM联合投加的试验。结果表明 :PAC +HPAM联合投加与HPAM一次投加相比 ,处理后水的浊度可降低 1 15～ 9 2 7倍 ,有利于去除水中的有机物。并且在沉淀后浊度大致相等时 ,HPAM用量可减少 4 0 %～ 6 0 % ,有利于降低饮用水中单体丙烯酰胺含量和其它有机物 。Three coagulant dosage experiments including the one shot dosage of hydrolytic polyacrylamide (HPAM), the split dosage of HPAM and the combined dosage of HPAM and PAC to treat high turbidity raw water were conducted. The results show that the combined HPAM + PAC dosage is more effective to remove the organic substances in raw water, the turbidity of the treated water will be 1.15 to 9.27 times lower than that of one shot dosage. In case to get post sedimentation water with same level of turbidity, about 40% to 60% of HPAM will be saved. This will be helpful to reduce the residual content of PAM monomers and other organic matters in drinking water.
