【Abstract】 The study of preparation of Ru-CeO₂-MnO₂/TiO₂ catalyst for catalytic wet air oxidation process the catalyst in which active components were Ru（0.5%）,Ce and Mn oxides supported on TiO₂ was prepared with technique of surface nanometerizing.The catalyst has been applied in catalytic wet air oxidation （CWO） process of simulated wastewater containing succinic acid and （NH₄）₂SO₄.It was found that its catalytic activity was acceptable by the dterminations of COD and T_N of the simulated wastewater.The ratio of removing COD was about 70%,and vatio of removing NH₃-N was 87.9%.更多还原
