摘　　要：采用Cu-Ce催化剂湿式氧化处理城市污泥（原始COD为12000mg／L），详细考察了反应温度、氧分压、进水pH值、催化剂投加量等对催化湿式氧化过程的影响，总结出最佳工艺条件。在此条件下，可将污泥的COD值从原来的12000mg／L降低到1903mg／L，COD去除率为84．5％，此时出水pH值为7．39。与相同条件下湿式氧化处理城市污泥相比COD去除率得到显著提高。The research is on the process of the muld in city in a wet oxidizing way with Cu-Ce catalysis （ The original COD is 12000mg/L） . The paper makes a detailed research about the influence of reactive temperature, partial pressure of oxygen, inlet pH, the amount of catalysis on the catalytic wet oxidation process, and comes to the conclusion of the best technological conditions. On these conditions, the COD value of the muld can be reduced to 1903mg/L from 12000mg/L; the wiping-out rate is 84. 5%; the outlet pH is 7.39. compared to COD wiping-out rate on the same conditions, the wiping-out rate of wet oxidation process of the muld in city has been improved a lot.
