高盐度垃圾渗滤液电催化氧化深度降解COD研究

Study on Deep Cod Degradation by Electrocatalytic Oxidation of High Salinity Landfill Leachate

生活垃圾成分的复杂性导致垃圾渗滤液的化学组成复杂多变,含有多种可生物降解和难降解的复杂基质,且含盐高,不易处理。本文通过采用电催化氧化系统对生化处理后的高盐度垃圾渗滤液进行深度处理,以进一步降解其中的COD。本实验考察了阳极材料、电压、极板位置、时间等因素对电催化氧化结果的影响,以期为垃圾渗滤液电催化氧化深度处理的应用提供技术支撑。

The chemical composition of landfill leachate is complex and varied due to the complexity of the components of domestic waste.It contains a variety of complex substrates that are biodegradable and difficult to degrade.In this paper,the electrocatalytic oxidation system was used to further treat the high salinity landfill leachate after biochemical treatment to further degrade COD.The effects of anode material,voltage,plate position and time on the results of electrocatalytic oxidation were investigated in this experiment,in order to provide technical support for the application of electrocatalytic oxidation of landfill leachate.
