| 摘 要： | 通过混凝试验，比较了聚铝、聚铁、聚铝铁三种混凝剂对水中痕量磷的去除效果，考察了pH值对聚铁、聚铝、聚铝铁除磷的影响，同时研究了聚丙烯酰胺（PAM）、高锰酸钾复合药剂（PPC）的助凝除磷效果。结果表明：聚铁混凝除磷效果明显好于聚铝和聚铝铁；三种混凝剂除磷最佳pH值分别为：聚铁7．5，聚铝6．5。聚铝铁6．0；pH值对聚铝、聚铝铁除磷的影响显著，对聚铁的影响较小；PAM和PPC具有较好的助凝除磷效果；将PAM和PPC联用能进一步提高助凝效果。

| Abstract: | Through coagulation experiments, trace phosphorus removal efficiency in water of three coagulants as poly aluminum chloride(PAC), pely ferric chloride(PFC),poly aluminum-ferric chloride(PAFC) and the variation of it with the change of pH were investigated. The effects of polyacrylamide(PAM) and permanganate composite chemicals (PPC) on improving phosphorus removal were also studied. The results showed that total phosphorus removal efficiency by PAC was evidently higher than those by the other two coagulating agents; the optimum pH values for PFC, PAC and PAFC to remove phosphorus were 7.5, 6.5 and 6.0, respectively; the effects of pH on PAC and PAFC were remarkable while pH effect on PFC was slight; both PAM and PPC had good performance in improving phosphorus removal efficiency while the combination of them present even better effect. |
