| 摘 要： | 以粉煤灰、废钢渣为原料制备了高效絮凝剂———聚硅酸铝铁,确定了制备PAC的最佳反应条件,并对其进行了处理废水实验。结果表明,由粉煤灰为原料制得的产品聚硅酸铝铁(PAFSi)比聚合硫酸铁(PFS)处理废水效果更佳。

| Abstract: | A practical method for the preparation of polyaluminum ferric silicate from coal ash and steel scraps was reported.The optimumre action conditions for the preparation of PAFSi,including molar ratio of reactants and the quantity of flocculating agent were determined.The results of the coagulation-flocculation experiments for treating waste water showed that the performance of PAFSi prepared from coal ash was much better than that of PFS. |
