摘　　要：染料中间体废水等难生物降解废水是目前水处理研究的焦点。用浸渍法和附着沉淀法制备了以γＡｌ２Ｏ３为载体的负载型镍、铜氧化物催化剂，并以催化吐氏酸废水的臭氧氧化。研究结果表明，镍、铜单组分和双组分氧化物催化剂能不同程度地提高臭氧的利用效率，其中附着沉淀法制备的ＮｉＣｕＵｒｅａ１催化剂活性最高，当臭氧投加量为０．８２ｇ／Ｌ时，其臭氧化指数为１．１；助剂钾对催化剂活性的影响与制备方法有关，当用浸渍法制备时，助剂钾能提高催化剂活性，而附着沉淀法时则不利。Poorly biodegradable wastewater,such as dye intermediate wastewater,is at present the research focus of water treatment. This paper studies the catalyzed ozonation of tobias acid wastewater, a typical dye intermediate wastewater, with catalysts of Ni and Cu oxides which are loaded over the γAl2O3 carrier by the methods of impregnation or absorptionprecipitation. It is shown that, catalysts of single oxide and complex oxides can improve ozonation efficiency in varying degrees, and catalyst NiCuUrea1 prepared by the impregnation method has the highest activity. When the ozone dosage arrives to 0.82g/L, its ozonation index is 1.1. In addition, the effect of additive K on the catalytic performance is preliminarily investigated. 
