摘　　要：以氯化铝、硫酸铁为主要原料制备了系列聚合氯化硫酸铝铁(PAFCS)絮凝剂.探讨了不同A1/Fe摩尔比、碱化度B、稳定剂用量、投加量等因素对混凝效果的影响,并考察了PAFCS预处理垃圾渗滤液的混凝效果.结果表明:在pH=6-8、A1/Fe摩尔比为4∶1、B=1.0、[A l]+[Fe]=0.08 mol/L时混凝效果最佳,各项混凝性能都明显优于PAC和PFS.A series of composite coagulants, poly-aluminum-ferric-chloride-sulfate (PAFCS) coagulant has been prepared by using AlCl_3, Fe_2(SO_4)_3 and vitriol as raw material.Some factors such as A1/Fe molar ratio, B, the dose of stabilization reagent and PAFCS on the coagulation effectiveness are studied, and the coagulation efficiency of PAFCS for landfill leachate is investigated. The experiment results showed that the best coagulation efficiency is gained when pH=6-8, A1/Fe=8∶2, B=1.0 and [Al]+[Fe]=(0.08mol/L), and PAFCS gave better coagulating effect than PAC and PFS.
