摘　　要：采用催化湿式氧化法对甲基橙模拟印染废水进行处理;催化剂的制备采用等量浸渍方法,以Cu、Fe为催化剂活性组分,Ce、La为催化助剂,加入贵金属钌制备多组分复合催化剂。研究了钌催化剂的加入对出水pH、吸光度和脱色率的影响。结果表明:加入钌催化剂处理后,出水pH呈先降低后升高的趋势,出水吸光度明显减小,脱色率增加显著,可达到98.3%。The simulated methyl orange dyeing wastewater was treated with catalytic wet air oxidation method; Using Cu and Fe as active components and Ce, La as promoters, the multi-component composite catalyst was prepared by adding ruthenium with the impregnation method. The influence of adding Ru into the catalyst on effluent pH, absorbance and decolorization rate was studied. The results show that： the effluent pH first decreases and then increases; the effluent absorbance decreases obviously, the decolorization rate increases significantly and can reach 98.3%.
