Research on the treatment of landfill leachate by the three-dimensional electrode process

实验利用火山石构建三维电极体系处理填埋场经预处理后的渗滤液,考察了电压、pH、Cl^-浓度对污染物质降解的影响效果,以寻求更高效的渗滤液处理工艺。在电解电压为10 V、Cl^-浓度为4000 mg·L^-1、原水pH条件下反应6 h后渗滤液氨氮、TP、COD去除率分别为23.72%,44.99%,60.92%。研究结果表明,该反应器对渗滤液降解具有一定效果。

In order to seek a more efficient domestic garbage leachate treatment process,volcanic stones were used to construct a three-dimensional electrode system.The leachate used in the experiment was already pretreated.The effects of voltage,pH and chloride ion concentration on the degradation of pollutants were investigated.Under the following conditions that the voltage of 10V,the chloride ion concentration is 4000mg·L^-1,and with the pH value of raw water and the reaction time of 6 hours,the removal rates of ammonia nitrogen,TP and COD were 23.72%,44.99% and 60.92%,respectively.The results indicated that the reactor can have an effect on the degradation of leachate.
