摘　　要：用天然高分子多糖(CTS)、聚合氯化铝(PAC)和助凝剂(改性物质P)等制备出一种环保型自来水复合絮凝剂,与传统的自来水絮凝剂PAC相比,这种絮凝剂使自来水的出水浊度、铝离子质量浓度和絮凝剂的药剂成本等分别下降了4.14%,40.3%和6.4%,具有明显的经济和环境效益。A kind of environment-friendly composite flocculant for treating tap water was prepared by using natural polysaccharide （CTS）, polyaluminum chloride（PAC） and coagulant aid（modified material P）. Compared with traditional flocculant PAC, the turbidity degree of treated tap water, AI^3 mass concentration and cost of flocculant reduced by 4.14%, 40.3% and 6.4% respectively. So the floceulant possesses obvious economic and environmental benefits.
