【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。更多还原

【Abstract】 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 electrode 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 amount of H2 O2 and·OH in the system,and has better efficiency in the degradation and removal of pollutants.更多还原
