电氧化法处理垃圾渗滤液膜滤浓缩液的试验研究

Experimental Study on the Treatment for Membrane Filtration Concentrate of Landfill Leachate by Electro-Oxidation

垃圾渗滤液膜滤浓缩液是垃圾渗滤液经生物降解后再经RO或NF膜截留的残余液,可生化性差、含盐量高、处理困难。本文采用电氧化法处理纳滤浓缩液,试验结果表明:电氧化法在纳滤浓缩液的处理上具有优势。在反应时间6h,对纳滤浓缩液的COD,TDS,Cl^-去除率分别达到82%,12%,51%,吨水耗电45k W·h。本试验研究在处理效果、能耗等方面达到了预期效果,为电氧化技术在纳滤浓缩液处理中的实际应用取得突破。

Landfill leachate membrane filtration concentrate is the raffinate intercepted by reverse osmosis membrane or nanofitration membrane,with low biodegradability,high salt content and difficult to be treated. In the research the electro-oxidation technology is applied to dispose the landfill leachate nanofiltration concentrated solution and it is satisfactory. Under the circumstances of 6 hours of electro-oxidation,the removal rates of COD,TDS and Cl-in the nanofiltration concentrated solution can reach 82%,12% and 51% respectively,with 45 degrees of power consumption per ton of water. The experiment has achieved the expected results in terms of energy consumption,treatment effect and so on,making a breakthrough in the practical application of electro-oxidation technology in the treatment of nanofiltration concentrated solution.
