摘　　要：以电厂粉煤灰为主要原料研制了一种新型复合混凝剂ＰＡＦＳ．实验了它对炼油工业废水的混凝处理能力以及对剩余污泥的脱水性能，并对其混凝机理进行了探讨．实验结果表明：ＰＡＦＳ在较宽的ｐＨ范围内对炼油工业废水具有良好的混凝处理效果，且破乳性能好；用于污泥脱水，具有投加量少，滤饼含水率抵，且滤液澄清，透光性好的特点．A new kind of complex coagulant PAFS has been prepared by using fly ash as primary row materials.Test about its application in refinery wastewater treatmint and sludge dewatering was made and the coagulation mechanism was discussed.The experimentalresults showed that PAFS has a good coagulation effect in disposal of refinery wastewater with wide scope of pH;after dewatering the water ratio of sludge decreased obviously,meanwhile the filter liquor was clarified.The coagulation effect of PAFS has a great advantage over PAC and PFS.
