摘要
通过混凝实验,比较了明矾、碱式氯化铝、聚合铝、聚铁以及硫酸铁5种混凝剂强化处理生活污水的效果,并分析了pH对COD、总磷去除率的影响。铝系混凝剂处理效果好于铁系混凝剂。
The application of different kinds of coagulants such as alum, alkaline aluminum chloride, poly-aluminum chloride (PAC), poly-ferric chloride (PFC) and ferric sulfate was compared. Coagulations of raw domestic wastewater using those chemicals respectively were studied in term of removal of COD, TN, TP and turbidity; effect of pH on coagulations was evaluated as well.Results indicated the better efficiency of alum-series coagulants than ferric-series ones.
