摘　　要：主要介绍以硫酸酸洗钢材废液为原料，利用空气制取新型混凝剂聚合硫酸铁（ＰＦＳ），并对长江水、池塘水和印染污水的净化处理，结果表明，ＰＦＳ有优良的混凝性能。A new coagulator polyferric sulfate(PFS) was prepared by two step oxidation and catalytic oxidation methods in which waste sulfuric acid picking was used as raw material. Through trial use in the Yangtse river, pond and waste solution of printing and dyeing with PFS, the PFS showed good coagulation propertica and wide application prospests.
