| 摘 要： | 研究了阳离子改性淀粉、两性芯粉与聚合氯化铝复合絮凝剂处理污水的效果.主要通过分析除浊率、投药量、CODCr去除率来比较不同絮凝剂对不同类型污水的处理情况.实验结果表明,这2种复合絮凝剂使用效果均优于单一絮凝剂.复合絮凝剂1号对高岭土废水的除浊率为98.41%;对南川河模拟废水的除浊率为92.35%,CODCr去除率为76.60%.复合絮凝剂2号对阿特拉津模拟废水的CODCr去除率为84.93%.

| Abstract: | The effects of two complexes(cationic modified starch flocculant and PAC,amphoteric starch flocculant and PAC) on the treatment of the different wastewater were investigated in terms of flocculants dosage,turbidity removal rate and CODCr removal rate.The turbidity removal rate of composite flocculant 1 was 98.41% on kaolin suspension;the turbidity removal rate was 92.35%,the CODCr removal rate was 76.60% on nanchuan stream.The CODCr removal rate of composite flocculant 2 was 84.93% on atrazine wastewater.Th... |
