摘要
将聚氯硫酸铝铁(PAFCS)与阳离子型聚丙烯酰胺(PAM﹢)复合并加入壳聚糖(CTS)制备新型生活污水絮凝剂。该絮凝剂用于处理普通城市污水的最佳配方比例是V(PAFCS)∶V(PAM﹢)∶V(CTS)=8∶6.5∶1,浊度去除率达到了90%以上,COD去除率也能达到75%以上。
The novel high - efficiency composite water flocculant was prepared by compounding PAF- CS, PAM + and CTS. The best formula for ordinary city wastewater is V(2% PAFCS): V(0. 2% PAM+ ): V(0. 2% CTS) = 8:6. 5:1. The removed rate of COD could be 75 percent, and the cost was 0. 144 yuan per ton.
