【摘要】 以硅酸钠、硫酸铁为原料制备了无机高分子絮凝剂聚硅硫酸铁(PFSS),确定了最佳制备条件,并实验了它的混凝除浊性能及印染废水COD的去除率,结果表明:PFSS具有良好的混凝除浊性能,印染废水COD的去除率比较高,是一种比PFS性能更优良的絮凝剂。更多还原

【Abstract】 Coagulant PFSS was prepared with water glass, and ferric sulfate as raw materials. The best n(Si)/n(Fe), the optimum activating pH value and activating time are determined. By the test, PFSS is much better than the PFS.更多还原
