| 摘 要： | 通过混凝实验,观察混凝除磷与除浊的关系,考察混凝剂品种、pH对混凝除磷效果的影响,以及混凝对水中不同形态磷的去除效果.研究高锰酸钾复合药剂(PPC)及聚丙烯酰胺(PAM)的助凝除磷效果.结果表明:强化混凝可以有效提高混凝除磷的效果;聚铁混凝除磷效果明显好于聚铝和聚铝铁;3种混凝剂除磷最佳pH分别为:聚铁7.5,聚铝6.5,聚铝铁6.0;溶解性磷的去除总体上来说更加困难,但是当混凝剂投量增加到一定水平,溶解性磷也能得到有效去除;PPC与PAM均具有一定的助凝除磷效果,但PAM的用量和投加时间必须很好控制.

| Abstract: | The relations between phosphorus removal and turbidity removal by coagulation are reviewed by laboratory experiments.The effects of coagulant types and pH value to removal performance of phosphorus with different forms are investigated.The coagulation aid effects of potassium permanganate composite(PPC) and polyacrylamide(PAM) on improving phosphorus removal are also studied.The results show that phosphorus removal efficiency is evidently improved by enhanced coagulation.The phosphorus removal efficiency of... |
