摘　　要：用不同催化剂对催化湿式氧化法在降解垃圾渗滤液作用方面的探索,通过实验测定悬浮物去除率的变化,筛选出高效催化剂,比较不同反应条件对悬浮物去除率的影响,优化操作条件,使其在催化湿式氧化处理垃圾渗滤液有较高的突破。最终确定最佳工艺条件为:催化剂用量0.372 g,金属离子质量浓度300mg/L,反应温度为180℃,氧分压为3.5 MPa,进水pH值为8.10,搅拌速度为500 r/min。Treatment effect of different catalysts for landfill leachate by catalytic wet oxidation degradation was studied.High-effective catalyst was screened out by measuring changes of suspended matter removal rate.Through comparing influence of reaction conditions on suspended mater removal rate,the best reaction conditions were gained as follows：catalyst dosage 0.372 g,metal ion concentration 300 mg/L,reaction temperature 180 ℃,oxygen partial pressure 3.5 MPa,pH value of water 8.10,stirspeed 500 r/min.
