高浓度聚合氯化铁混凝剂的净水效果
WATER PURIFICATION BY HIGH-CONCENTRATION POLYFERRIC CHLORIDE(PFC)COAGULANT
-
摘要: 采用共聚方法制备聚合氯化铁混凝剂.试验了它对模拟水的除浊和脱色效果,对高、中、低浊度的地表水以及炼油废水的处理效果.实验结果表明:与FeCl3相比,聚合氯化铁(PFC)具有更好的除浊、脱色效果,COD去除率、除油率的效果大大提高;W/Fe摩尔比对PFC混凝效果的影响不尽相同,在实际水处理中,应根据处理对象的不同,选择合适的参数以达到最佳的混凝效果.

Abstract: A series of high concentration polyferric chloride(PFC)were prepared by copolymerization.The removing turbidity and decolorization efficiencies were studied in the simulating water,and the dispose efficiencies for higher,medium and lower turbidity water were also investigated.The diffe rences between PFC and FeCl3 were compared.The experiment results showed that PFC is superior to the FeCl3 in term of the removing turbidity,colour,COD,oil and UV254;W/Fe molar ratio have different influences on the coagulating properties of PFC for unlike water.In water treatment it is necessary that appropriate parameters are chosen according to different objects of treatment to obtain optimum coagulating effectiveness.-
