摘　　要：对以ClO2氧化印染废水用的负载铜活性炭催化剂制备工艺进行了研究。实验结果表明:该催化剂的最佳制备工艺为:酸浸液浓度2.5mol/L,浸渍12h;硝酸铜浸渍液质量分数7.5%,浸渍后活性炭先室温干燥,后80℃烘干,再在280℃下焙烧3h。并通过对实际印染废水的处理确定了最佳催化氧化工艺。失活催化剂经再生处理,可恢复约90%的催化活性。The catalyst, which is composed of activated carbon as carrier and loaded with copper oxide (CuO) as active component,was made and main factors in the preparation of this catalyst were further analyzed. Under the optimized preparation condition of nitric acid 2.5mol/L ,soaking time 12h , concentration of Cu(NO_3)_2 7.5% , calcination temperature 280℃ for 3h , the optimum catalytic activity could be obtained. The best catalytic oxidation process of dye wastewater treatment was also investigated by this catalyst. The regeneration process of deactivated catalyst was also investigated and the activity of regenerated catalyst was recovered to about 90% .
