摘　　要： 对聚硅硫酸铝 (PASS)的混凝性能及其对处理后水中的残留铝的影响进行了研究。另外 ,对处理后水中残留铝的来源及降低残留铝的方法进行了探讨。 The coagulation performance of polyaluminium silicate sulfate (PASS) a nd the amount of residual aluminum were researched. The effects of SiO_2/Al, curing time, stirring time, and pH on coagulability and residual al uminum were investigated. Experimental results show that the coagulation performance of PASS is better than aluminum sulfate, and the residual alumin um is lower. The favorable properties of PASS increase with the increasing of SiO_2/Al mole ratio. In addition, the source of residual aluminum and its decreasing methods were discussed.
