Study on treatment of nondegration landfill leachate by electrolytic oxidation process
电解氧化处理难降解垃圾渗滤液研究

A continuous flow electrolytic through system was studied for the treatment of landfill leachates. The influences of electrode distance, current densities and chloride concentration on removal efficiencies were studied. The results showed that electrolytic oxidation process was effective on treatment of middle strength landfill leachates, when COD was less than 3000 rag/L, added chloride concentration was 6000 rag/L, the time was 60 minutes. The removal rates of COD and NH3-N can come up to 88.9% and 97.3% ,respectively,the energy consumed was 2.75 kWh/m^3. A valuable reference could be provided for a pilot scale research and industrial application.
