摘　　要：实验采用硅酸钠、硫酸铁、硫酸镁制备聚硅酸铁镁絮凝剂。结果表明,聚硅酸浓度为0. 4mol/L,活化pH为3-4, Si/(Fe+Mg)摩尔比为1. 5时, Fe/Mg摩尔比为0. 8时,制备的絮凝剂,除浊率较高。The polysilicate ferric magnesiunl flocculant was prepared through sodium silicate,ferric sulfate,Magnesium sulphate as the raw materials.The results show that the removal rate of turbidity was higher when the concentration of sodium silicate was 0.4mol/L,activation pH was 3-4,n（Si）：n（Fe＋Mg）molar rate was 1.5,n（Fe）：n（Mg） molar rate was 0.8.
