摘　　要：实验采用催化湿式氧化法对甲基橙模拟偶氮染料废水进行处理;催化剂的制备采用等量浸渍法,以Cu、Fe为催化剂活性组分,制备多组分复合催化剂,研究了催化剂组分构成对催化剂性能的影响。实验结果表明,双组分催化剂Cu-Fe的性能优于单组分的Cu、Fe催化剂。在甲基橙浓度为0.238 g/L、反应总压力为2.5 MPa、反应温度为180℃、搅拌速度为500 r/min、反应时间为3 h的条件下,废水处理的脱色率达96%。Methyl orange azo dye wastewater was processed with catalytic wet air oxidation method; Multi-component composite catalysts were prepared by isometric impregnation method with Cu and Fe as active components. Effects of catalyst component on catalytic performance were researched. The experimental results show that Cu-Fe bicomponent catalyst is superior to single component Cu or Fe catalyst. When methyl orange concentration is 0.238 g/L, total reaction pressure is 2.5 MPa, reaction temperature is 180 ℃, stirring speed is 500 r/min, reaction time is 3 h, treatment effect of the wastewater is very good, the decolorization rate can reach to 96%.
