| 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．

| Abstract: | In this paper,a novel metal-polysilicate coagulant is used in low turbid water which from a southern fiver treatment plant.The coagulation efficiency and the features of the metal-polysilicate coagulants with different molar ratio of Al to Fe are compared by meas- uring the removal efficiencies of turbidity,the removal efficiencies of color,the residual alu- minum and total iron,the differences among this sort of coagulants with different AI/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-polysili- care is applicable for southern China low turbid water in the paper. |
