Abstract:

In this paper, a study on preparing a new flocculant )polyferric chloride phosphate ( PPFC) is reported. The effect of PPFC compar ed with PFC in the treatment of / model0 water and industrial w aste water w as inv est igated in a series of coagulation jar tests. The per fermance of PPFC was found to besuper ior to PFC in the removal of COD and turbidity, which ind-icate that PO₄^3- improves PFC polymerizat ion and its coagulation coagulation properties.

摘要：

在干法制备聚合氯化铁（PFC）的过程中，加入不同配比的磷酸盐（Na₂HPO₄·12H₂O）,制得新型混凝剂聚磷氯化铁（PPFC）.通过混凝搅拌实验得到PPFC的最佳制备条件及最佳含磷量。将PFC和PPFC分别对三种工业废水进行对比混凝实验，结果表明，PPFC对废水的COD和浊度去除率均优于PFC.表明了PO₄^3-对聚合铁有增聚作用。
