摘　　要：采用浸渍-焙烧法制备了Cu/C-Al2O3。以Cu/C-Al2O3为催化剂,臭氧为氧化剂,对印染废水进行了催化臭氧化处理,考察了催化剂投加量、氧化剂浓度、pH和反应时间等因素对处理效果的影响。结果表明:当pH为9,催化剂投加量为10 g/L,O3质量浓度为55 mg/L,反应时间为60 min时,COD去除率达到60%,色度去除率达到96%。Catalyst Cu/C-Al2O3 has been prepared by impregnation-calcination method. The dyeing wastewater has been treated by catalytic ozonization process,using Cu/C-Al2O3 as catalyst and ozone as oxidant. The effects of fac-tors,such as dosage of catalyst,concentration of oxidant,pH,reaction time,etc. on treatment effectiveness are inves-tigated. The results show that when pH is 9,catalyst dosage 10 g/L,mass concentration of O3 55 mg/L and reaction time 60 min,the COD removing rate reaches 60%and removing rate of chroma reaches 96%.
