摘　　要：文章论述了用催化湿式氧化法对炼油碱渣废水进行处理,考察了催化剂活性组份种类、载体种类和负载量等因素对催化剂性能的影响。实验结果表明:加入催化剂可明显提高化学需氧量(COD)去除率,且MnSO4的催化性能要高于Cu(NO3)2,以γ-Al2O3为载体负载10%MnOx的催化剂,在一定条件下对碱渣废水的COD去除率可达77.8%。Refinery Alkaline Residue was treated by catalytic wet oxidation, The effect factors of the type of active ingredients and supports, Mn loadings were researched. It were concluded that the remove rate of COD can be raised when catalyst was input. It also be found that MnSO4 has higher catalytic activity than Cu（NO3）2. The most efficient of 77.8% COD remove rate was obtained by 10% MnOx supported on γ-Al2O3 on the stated condition.
