摘　　要：采用阳离子淀粉作为絮凝剂对染料废水进行处理,研究其絮凝性能.探讨了阳离子淀粉的用量、废水pH及絮凝时间和温度对絮凝效果的影响,确定了阳离子淀粉处理染料废水的最佳条件.试验结果表明:阳离子淀粉对染料废水有较好的絮凝效果,其絮凝效果与聚铝絮凝剂相近.Cationic starch was used to treat the dyeing wastewaters to investigate its flocculation properties. The influences of cationic starch amt., wastewater pH, flocculation time and temp. on the flocculation results were researched, and the optimal conditions were detd. The results showed that the cationic starch gave good effects when treating dyeing wastewater, and the results were similar to those with polymeric AI flocculants..
