| 摘 要： | 通过实验室杯罐试验,对水厂滤池反冲洗废水的混凝沉淀处理进行了研究.分别采用硫酸铝、聚合氯化铝和三氯化铁为混凝剂,在不同混凝剂投量下的对色度、浊度、CODMn、及UV254的去除效果进行了考察.试验结果表明,对浊度和色度的去除,最佳混凝剂为聚合氯化铝PAC,而对其有机物的去除三氯化铁则最佳.按除浊要求得到的最佳混凝剂投量但不能满足对有机物的去除,所以选择哪种混凝剂及投加量应根据对反冲洗废水的处理要求等综合慎重考虑.

| Abstract: | The filter backwash wastewater was treated by the jar tests with three different coagulants,in order to investigate the removal of turbidity,color,CODMn and UV254.As the result,the optimal coagulant is poly-aluminum chloride for removal of turbidity and color,and that is ferric chloride for removal of organic matters.Turbidity removal requested by the best coagulant dosage can not meet the removal of organics,the coagulant and dosage could be decided by backwash wastewater treatment requiresments comprehensive calculations. |
