摘要
对工业废水及生活污水的处理实验对比研究以及对PPFC形态结构的研究结果表明 ,PPFC对几种废水的浊度和COD去除率均超过聚氯化铝、氯化铁、聚氯化铁 ,与聚硫酸铁效果相当。与聚氯化铁相比 ,PPFC的形态分布及结构也发生了很大变化 ,特别是PPFC中Fe(b)的量大大增多 ,这正是PPFC混凝性能提高的原因。
From comparative test on treatment of industrial and household waste water and study on PPFC species,it is shown that the removal rate of PPFC for the turbidity and COD of several sorts of waste water is larger than PFC.And espcially,the amount of Fe(b)in PPFC has increased greatly compared with PFC,that is why the coagulation of PPFC is enhanced.
