摘要
采用Fenton、电催化氧化、臭氧氧化等3种高级氧化技术对垃圾渗滤液的生化出水进行深度处理,考察了这3种技术对废水COD的去除效果及影响因素。结果表明,在最适宜的反应条件下,3种高级氧化技术Fenton、电催化氧化、臭氧氧化深度处理垃圾渗滤液生化出水的COD最大去除率分别到达了73%、58%和75%。并从处理效果、处理成本、操作难易程度、有无二次污染、工程应用可行性等方面对这3种高级氧化技术进行比较,确定出臭氧氧化技术为最适宜的工艺。
Fenton, electro-catalytic oxidation and ozone oxidation were used in the advanced treatment of biochemical effluent of landfill leachate. The removal effect of COD and influencing factors were investigated. The results showed that the greatest removal rate of COD of biochemical effluent of landfill leachate reached 73%, 58% and 75% treated by three kinds of advanced oxidation technology including Fenton, electro-catalytic oxidation and ozone oxidation. Ozone oxidation was determined as the optimal process by comparing from the aspects of the treatment results, treatment costs,difficulty level of operation, with or without secondary pollution, engineering application feasibility.
