摘　　要：用壳聚糖、聚铝及助剂A等材料复合制备出一种新型环保型自来水处理复合絮凝剂,其最佳使用配比为:V(0.01%壳聚糖)∶V(0.5%聚铝)∶V(0.5%助剂A)=1∶3∶1。该复合絮凝剂与传统的聚铝类自来水絮凝剂相比,其出水浊度和铝离子质量浓度分别下降了10.2%和61.9%,絮凝剂的药剂成本下降约7.1%,具有显著的经济与环境效益。Compounding chitosan with poly aluminum chloride and assistant agent A, a novel environmental floeculant was obtained. The optimum proportion of the floeculant is V（0. 01% chitosan） ： V（0. 5% poly aluminum chloride） ： V（0. 5% A） = 1：3：1. The turbidity of water leakage and its content of aluminum is decreased 10.2% and 61.9%, respectively; its cost is 7.1% lower than that of traditional flocculant （PAC）. So it has obvious economic and environmental benefits.
