摘　　要：以聚合氯化铝(PAC)和聚环氧氯丙烷胺(EPI-DMA)为原料,制备出PAC-EPI-DMA复合絮凝剂,利用电子透射电镜(TEM)研究了EPI-DMA和PAC-EPI-DMA在水中的聚集形态,并对PAC、EPI-DMA和PAC-EPI-DMA在处理模拟染料废水和实际印染废水时的絮凝性能进行了对比实验。实验结果表明:PAC-EPI-DMA较EPI-DMA在水溶液中的结构形貌有较大差异。将EPI-DMA与PAC复配可以增强絮凝剂的电中和与吸附桥连作用,使絮凝处理的效果更佳。Composite floceulants polyaluminum （PAC）- epichlorohydrin-dimethylamine polymers （EPI-DMA） was prepared by using PAC and EPI-DMA as raw materials. The morphology of EPI-DMA and PAC-EPI-DMA were studied by TEM. Jar tests were performed to test the coagulation efficiency of PAC, EPI-DMA and PAC-EPI-DMA in treating synthetic or actual water samples. The results showed that compared with PAC and EPI-DMA, PAC-EPI-DMA gave the best coagulation results, and achieved the highest charge-neutralizing and adsorption bridge building ability.
