| 摘 要： | 研究絮凝剂硫酸铝Al2(SO4)3与助凝剂聚丙烯酰胺(PAM)联合处理生活污水的效果。研究表明:Al2(SO4)3与PAM联用比单独用Al2(SO4)3处理生活污水效果更好;Al2(SO4)3 PAM对生活污水CODCr和浊度具有良好的去除能力;当投加1:1的50mg/L的Al2(SO4)3 0.5mg/L的PAM,调节水体pH=7时,处理效果最理想,CODCr去除率可达95.8%,浊度去除率可达97.5%。为复合絮凝剂Al2(SO4)3 PAM处理生活污水的应用提供了有价值的参考依据。

| Abstract: | The effect of aluminum sulfate [Al_2(SO_4)_3] flocculent combined with ployacrylamide (PAM) co-flocculent on the treatment of domestic sewage was studied. The results indicate that the effect of Al_2(SO_4)_3 combined with PAM is better for the treatment of domestic sewage than that of a single Al_2(SO_4)_3, and Al_2(SO_4)_3 PAM can significantly remove CODCr and turbidity of domestic sewage. When 50mg/l and 0.5mg/l PAM were added, and pH was controlled at 7, the result is the most satisfactory: COD_(Cr) removal is 95.8%, turbidity removal is 97.5%. Meanwhile, the results are valuable references to the application of Al_2(SO_4)_3 and PAM in combination on the treatment of domestic sewage. |
