摘要：

采用催化湿式氧化法，对高浓度难生化垃圾渗滤液进行处理。催化剂活性以垃圾液的COD去除率和脱色率进行评价。对11种可溶盐的研究表明，硝酸钴具有最强的催化活性，且其催化活性随用量的增加而提高，双组分催化剂的复配没有发生协同增效作用。不同反应时刻垃圾液的紫外光谱分析表明，随着反应时间的延长，垃圾液的组分数量和浓度明显降低。

Abstract:

Catalytic wet air oxidation（CWAO）technology was applied to process the highly concentrated and biorefractory garbage leachate. Activity of catalysts was evaluated by the COD removal and decolorization rates of the garbage liquids. 11 kinds of soluble inorganic salts were evaluated for the catalytic process，in which cobalt nitrate showed the highest catalytic activity，the bicomponent catalyst did not show any synergetic effect. UV-vis spectra analysis indicated that both the components and their concentrations in the garbage liquids significantly reduced with the increase in treatment time.
