摘　　要：研究用壳聚糖、聚铝和助剂 A 复合制备出一种成本低、絮凝效果好、出水铝离子含量少的新型自来水处理絮凝剂,并确定其最佳配比为:v(0.1%壳聚糖):v(2%聚合氯化铝):v(0.1%助剂 A)=1:6:5。此絮凝剂与传统聚铝类絮凝剂相比,其出水浊度和铝离子质量分数分别下降了2.97%和10.7%,并且药剂成本下降6.25%,有明显的经济和环境效益。A novel composite flocculant prepared by compounding chitosan with poly aluminum chloride and assistant agent A, which is of lower cost and Al^3＋ concentration, was studied. The optimal volume ratio of this flocculant was v （ 0.1% chitosan） ：v （2% Poly aluminum chloride）： v （0.1% ingredient A） = 1：6： 5. Compared with the traditional flocculant PAC, the turbidity degree, Al^3＋ concentration and cost of this flocculant reduced 2.97%, 10.7% and 6.25% respectively. It has obvious economic and environmental benefits.
