摘　　要：研究了以炼钢污泥为原料制备聚合硫酸铁铝(PFAS)的方法,确定了合理的生产工艺和制备条件,用该絮凝剂处理焦化废水,并与聚合硫酸铁(PFS)的处理效果比较,结果表明,出水的CODCr、总氰化物、挥发酚、色度去除率分别提高约16.9%、12.5%、5.1%和5.3%。A preparation method of high efficient coagulant of poly-ferric aluminum sulfate（PFAS） using steelmaking sludge as main material was studied.The rational production process and operating conditions were discussed.The coagulant was tested in coking wastewater treatment and compared with poly ferric sulfate（PFS）.It has been found that the removal rates of CODCr and total cyanide are16.9% and 12.5%,and the removal rates of phenol and color are increased by about5.1% and 5.3%.
