摘　　要：以包钢高炉煤气洗涤水处理系统为研究对象,通过静态混凝沉淀试验,确定复合混凝剂最佳配比为聚合硫酸铁10mg/L、聚丙烯酰胺0.1 mg/L、石灰25~250mg/L（调节pH值为8.5左右）。处理后,出水清澈透明、浊度低,絮体大而密实、沉降速度快,水质能够达到回用水水质指标要求。By taking the treatment system of blast furnace gas washing water in Baotou Iron and Steel Company as the study object,the static coagulation precipitation experiments are performed to determine the best ratio of composite coagulant which is PFS 10 mg/L,PAM 0.1 mg/L,lime 25-250 mg/L（adjusting pH value to 8.5 or so）.After the treatment,the reuse water is clear and transparent with low turbidity,the floc is big and dense with fast settling velocity,and the water quality can meet the requirements of recycle water indicators.
