摘　　要：选用季铵型阳离子脱色剂与聚合氯化铝(PAC)复配对印染废水进行深度处理。研究结果表明,复合絮凝剂处理印染废水效果较好,在pH值为8的条件下,当季铵型阳离子脱色剂投加量为4 mg/L,PAC投加量为10 mg/L时,印染废水的脱色率可达91.2%,COD去除率达58.6%。季铵型阳离子脱色剂和PAC复配使用能降低投药量、提高处理效果,应用于印染废水深度处理的前景良好。The printing and dyeing wastewater is treated by using quaternary ammonium type cationic decolorizing agent and PAC. The results show that the dosages of quaternary ammonium type cationic decolorizing agent and PAC are 4 mg/L and 10 mg/L respectively,and pH value of 8, the decolorization rate can reach 91.2% and the removal of COD can reach 58.6%. Quaternary ammonium type cationic decolorizing agent can enhance the treatment efficiency with less dosage when used with PAC. This method has a good application prospect in tertiary treatment of printing and dyeing wastewater.
