摘　　要：采用碱化法制备聚合硫酸铁,并引入PO34-制备出新型无机高分子絮凝剂聚合磷硫酸铁(PPFS)。正交实验结果表明制备PPFS最佳工艺条件为:反应温度50℃,反应时间3 h,PO34-/Fe3+(摩尔比)0.1,盐基度0.5。高浊度模拟废水处理结果表明最佳操作条件为:PPFS在废水中的质量浓度为10 mg/L,废水的pH值为8;在最佳处理条件下,模拟废水浊度去除率达到99.14%,其絮凝效果和沉降性能明显优于聚合硫酸铁和聚合氯化铝。A novel inorganic macromolecule flocculent of polyferric phosphate sulfate （PPFS） was synthesized by introducing phosphate anion into polyferric sulfate. The following optimal reaction conditions were obtained by orthogonal experiment： reaction temperature 50℃ , reaction time 3 h, PO4^3-/ Fe^3＋ （mole ratio） 0.1 and basicity 0.5. The results of flocculation experiment for a simulating waste water with high turbidity showed that the optimum operating conditions were：pH value of waste water 8 and mass concentration of PPFS in sewage 10 mg/L. Under these conditions,the removal rate of turbidity eould reach 99.14% and the effects of floceulation and deposition of PPFS was much better than polyferric sulfate and polyaluminium chloride.
