摘　　要：以酸性黑染料废水为处理对象,对多相催化氧化处理工艺中的铜系催化剂进行研究。结果表明,以α-Al2O3为载体制得的铜系催化剂活性较高。该载体在浓度较高的硝酸铜溶液中浸渍2次,每次浸渍(4～6)h,在焙烧温度450℃和焙烧3h的条件下,所制备的催化剂处理酸性黑染料废水,COD去除率均>66.5%,色度去除率>97%。Treatment of acidic black dye wastewater by multi-phase catalytic oxidation over copper catalyst was studied. The results showed that the copper-based catalyst supported on or-Al2O3 had high catalytic activity. The support was impregnated in cupric nitrate solution for two times for （4 -6） h and calcined at 450 ℃ for 3 h. COD removal of 66.5% and chroma removal of 97% were obtained over the catalyst in treatment of acidic black dye wastewater.
