摘要
构建了三维电极系统,对垃圾渗滤液纳滤浓缩液进行电催化氧化处理,并探讨催化反应机理。在5.5 V电压下用二维和三维电极系统对纳滤浓缩液进行处理,结果表明,三维电极系统的COD去除率为70.35%,显著优于相同条件下的二维电极系统(58.58%),三维电极系统出水中的可溶性有机物含量明显降低。粒子电极的加入提高了系统中H2O2和·OH的生成量,在污染物的降解和去除上有更优异的效能。
A three-dimensional electrode system is constructed to treat landfill leachate nanofiltration concentrate by electrocatalytic oxidation,and the mechanism of catalytic reaction is discussed.Nanofiltration concentrate is treated by two-dimensional and three-dimensional electrode systems at 5.5 V.The results show that the COD removal rate of the three-dimensional electrode system is 70.35%,which is significantly better than that of the two-dimensional ele-ctrode system(58.58%)under the same condition.The content of dissolved organic matter in the effluent from the three-dimensional electrode system is significantly reduced.The addition of the particle electrode increases the amo-unt of H2O2 and·OH in the system,and has better efficiency in the degradation and removal of pollutants.
