摘　　要：以酸洗废液和氯酸钙粉为原料,采用氧化聚合法制备出聚合氯化铁铝(PFAC)絮凝剂,并用PFAC处理分别处理含有分散蓝106和酸性大红GR的印染废水,考察各因素对去除效果的影响。实验结果表明:染料的去除率主要受PFAC的投加量和初始pH的影响;PFAC处理分散蓝106的能力强于处理酸性大红GR,并且对分散蓝106和酸性大红GR的最佳投加量及温度分别为260 mg/L、20℃,最佳初始pH分别为7、6,对应的最佳去除率分别为98.5%、75.7%,单位质量的PFAC对分散蓝106和酸性大红GR的去除量分别为1.32 mg/mg、0.62 mg/mg。Polyferric aluminum chloride flocculants （PFAC） were prepared from spent pickling liquors and calcium aluminate via oxidation and polymerization. The wastewater containing disperse blue 106 and acid brilliant scarlet GR was treated by PFAC and the factors affecting the flocculating effect were investigated. According to the results, the dye removal was dependent on the pH and coagulant dosage.
