通过共沉淀制备了４类主活性成分分别为Ｃｕ、Ｃｅ、Ｃｄ和Ｃｏ－Ｂｉ的粉末催化剂，用于催化湿式氧化（ＣＷＡＯ）处理染料中间体Ｈ－酸溶液．通过实验确定了催化湿式氧化的条件．不同催化剂的处理效果比较表明，Ｃｕ／Ｃｅ（３∶１）催化剂较好．当反应温度为２００℃，氧分压为３．０ＭＰａ，ｐＨ＝１２．０，反应时间为３０ｍｉｎ时，ＣＯＤ的去除率大于９０％． Four kinds of powder catalysts with main active components of Cu, Ce, Cd and Co-Bi were prepared by coprecipitation for the catalytic wet oxidation (CWAO) treatment of dye intermediate H-acid solution. The conditions of catalytic wet oxidation were experimentally determined. Comparison of different catalyst treatment results show that Cu / Ce (3: 1) catalyst is better. When the reaction temperature is 200 ℃, the partial pressure of oxygen is 3.0MPa, pH = 12.0, the reaction time is 30min, the COD removal efficiency is more than 90%.
