摘　　要：以工业废渣煤矸石为原料制备了聚合氯化铝(PAC),确定了制备优化条件,利用制备的PAC进行处理生活污水和印染废水试验,并与市售PAC进行了对比试验。结果表明,废水的pH在6.0～10.0时,浊度去除率和COD去除率效果均较好,煤矸石PAC适宜的投加量为0.3～0.5 mL/L;由煤矸石为原料制得的PAC比市售PAC处理废水效果更佳。The polymeric aluminum chloride（PAC） was prepared by using industrial waste coal gangue as raw materials.The optimum preparation condition of PAC was determined.Treatment of domestic sewage and dyeing wastewater were performed by PAC.The results show that the removal rate of turbidity and COD is well when the pH value range from 6.0 to 10.0,and the better dosage range of PAC from 0.3～0.5 mL/L.The wastewater treatment effect of PAC prepared from coal gangue is much better than that of commercial PAC.
