摘　　要：基于以硝酸铜为活性组分的前驱物,采取浸渍焙烧法制备了CuO/活性炭催化剂,并以H_(2)O_(2)为氧化剂,对比了在常压条件下催化湿式氧化工艺中处理质量浓度500 mg·L^(-1)甲基橙模拟废水的效果,分别考察了不同CuO/活性炭催化剂加入量、质量分数30%的H_(2)O_(2)氧化剂用量、脱色反应时间、脱色反应温度对甲基橙废水脱色率的影响。结果表明:随着CuO/活性炭催化剂加入量、30%H_(2)O_(2)氧化剂用量、反应温度的不断增加,甲基橙废水的脱色率明显增大;而增加反应时间对甲基橙废水脱色率增加幅度较小。当CuO/活性炭催化剂加入量为0.1 g、质量分数30%H_(2)O_(2)氧化剂加入量为6 mL、催化反应时间为2 h、催化反应温度为35℃时,其对甲基橙废水的脱色率可达到82.44%。Based on the precursor with copper nitrate as the active component,CuO/activated carbon catalyst was prepared by impregnation roasting method,and H_(2)O_(2) was used as the oxidant to compare the effect of treating simulated-1 wastewater of methyl orange with mass concentration of 500 mg·L^(-1) under atmospheric pressure in the catalytic wet oxidation process.The effects of different amounts of CuO/activated carbon catalyst and 30%mass fraction of H_(2)O_(2) oxidant,decolorization reaction time,and decolorization reaction temperature on the decolorization rate of methyl orange wastewater were investigated.The results showed that with the continuous increase of CuO/activated carbon catalyst dosage,30%H_(2)O_(2) oxidant dosage,and reaction temperature,the decolorization rate of methyl orange wastewater significantly increased.However,increasing the reaction time had smaller effect on the decolorization rate of methyl orange wastewater.When the amount of CuO/activated carbon catalyst added was 0.1 g,the amount of 30%H_(2)O_(2) oxidant added was 6 mL,the catalytic reaction time was 2 h,and the catalytic reaction temperature was 35℃,the decolorization rate of methyl orange wastewater could reach 82.44%.
