催化湿式氧化处理有机废水的催化剂研究

Study on the Performance of Catalysts for Catalytic Wet Oxidation Treatment of Organic Wastewater

对于湿式催化氧化法,不同的催化剂对于不同种类的废水都有着各自的最佳适用范围。文章研究重点主要集中在非均相催化剂,研究工作主要包括催化剂的筛选制备以及催化剂的评价研究。催化剂的筛选及制备包括活性组分的选择、载体的选择以及制备方法的选择。综合比较COD去除率和金属溶出量的测定结果,筛选出Cu-Ce/TiO_(2)-ZrO_(2)催化剂为最佳催化剂。

For the wet catalytic oxidation method,different catalysts have their own best applicable ranges for different wastewater.The research focus of this paper is mainly on heterogeneous catalysts,and the research work mainly includes the screening and preparation of chemical agents and the evaluation of catalysts.The screening and preparation of catalysts include the selection of active components,the selection of carriers,and the selection of preparation methods.A comprehensive comparison of the COD removal rate and the determination of the amount of metal leaching,the Cu-Ce/TiO_(2)-ZrO_(2) catalyst was selected as the best catalyst.
