摘　　要：[目的]为了探讨聚丙烯酰胺改性后聚丙烯酰胺接枝淀粉絮凝剂的絮凝性能。[方法]通过对高浊度水样、低浊度水样以及生活污水的絮凝试验,讨论合成PAM-g-St(Ⅰ)、PAM-g-St(Ⅱ)和CPAM-g-St(Ⅲ)与硫酸铝复配使用时的絮凝效果。[结果]3种合成絮凝剂的絮凝效果对高、低浊度水样浊度的去除率均可达99%,对生活污水浊度的去除率为70%～92%,对COD的去除率为56%～69%。[结论]PAM-g-St(Ⅰ)、PAM-g-St(Ⅱ)和CPAM-g-St(Ⅲ)对水源水的絮凝性能优于PAM,但对生活污水的絮凝效果不太理想。[Objective] The research aimed to discuss the efficiency of the coagulant aids of polyaerylamide grafted starch （PAM-g-St） floeeulants modified from polyaerylamide. [Method] By using the test of the coagulation aid of high turbidity water, low turbidity water and wastewater, the effieieneies of the synthesized PAM-g-St（ Ⅰ ）, PAM-g-St（ Ⅱ ）, CPAM-g-St（Ⅲ ） compounded with alum were studied and discussed. [Result] The results showed that 99% turbidity could be removed from high and low turbidity water samples, 70%-92% turbidity of the sewage and 56%-69% chemical oxygen demand （COD） could be removed by the three synthesized coagulant aids. [Conclusion] The coagulation aid effects of PAM-g-St （ Ⅰ ）, CPAM-g-St（ Ⅱ ） and CPAM-g-St （Ⅲ） were better than PAM for water from water sources, but they were not so effective for wastewater.
