摘要
试验以低浊度的某江水为原水,采用一种新型的聚硅酸金属盐混凝剂(Polysilicic acid,Alu- minium and Ferric Salt,缩写为PAFS)进行净化试验．通过试验测定投加不同Al与Fe物质的量的比值的聚硅酸金属盐混凝剂混凝沉淀后水的余浊、色度、残余铝质量浓度及总铁质量浓度,比较了Al与Fe物质的量的比值对聚硅酸金属盐混凝剂的影响,及所表现出来混凝效果的差异．并分析了PAFS混凝机理是吸附架桥和电中和作用共同结果,初步验证了这种混凝剂处理低浊水质的适应性．
In this paper, a which from a southern river the metal-polysilicate coagul novel metal-polysilicate coagulant is used in low turbid water treatment plant. The coagulation efficiency and the features of ants with different molar ratio of A1 to Fe are compared by measuring the removal efficiencies of turbidity, the removal efficiencies of color, the residual aluminum and total iron, the differences among this sort of coagulants with different A1/Fe ratios are investigated. The coagulant removes colloid impurity by adsorption bridging and electrical neutralization of inorganic polymer coagulant with long chains, the presented metal-polysilicate is applicable for southern China low turbid water in the paper.
