| 摘 要： | 聚硅酸硫酸铝铁（PSAFS）是一种新型的混凝剂。实验研究了水解度、熟化时间、加入剂量以及水体酸度等对除磷效果的影响，并对除磷机理进行了分析。实验结果表明，在2．5％的硅酸钠，pH为5．3时，活化15min，水解度为0．8，以及6d熟化的条件下，磷去除率可达95％。

| Abstract: | A new coagulant,polysilicate aluminum ferric sulfate(PSAFS) was prepared to study the effect of its hydrolytic degree,ripening time,dosage and water acidity etc.on phosphorus removal;the mechanism of phosphorus removal was analysed.The results showed that,under the conditions of 2.5% sodium silicate,pH5.3,activating time 15 min,hydrolytic degree 0.8 and ripening time 6 days,phosphorus removal rate was as high as 95%. |
