摘　　要：本文采用碱化法,在引入PO_4^(3-)制备聚合磷硫酸铁的过程中加入改性凹凸棒,制备出新型无机高分子絮凝剂聚合磷硫酸铁-凹凸棒(APPFS)。生活污水处理结果表明:APPFS投加量32mg/L,废水p H值为8左右,沉降10min为最佳絮凝条件,除浊率达到94.91%,CODCr去除率达到63.40%。在最佳絮凝条件下,絮凝剂APPFS的絮凝性能明显优于PFS。A novel inorganic macromolecule flocculant ofpolyferric phosphate sulfate-attapulgite（APPFS） has been synthesized by introducing phosphate ion into polyferric sulfate and adding modified attapulgite. The optimal conditions were obtained by flocculent test of sewage water： the dosage of APPFS solution 32mg/L,pH value of waste water 8,sedimentation time around 10 rain. Under the above conditions, the removal rate of turbidity and CODCr are 94.91% and 63.40%.Under the same best conditions,the flocculation efficiency of APPFS is much better than PFS
