摘　　要：本文选用Ti/BDD、Ti/SnO2SbO3CuO、Ti/PbO2、Pt/Ti、Ti/RuO2电极对生活垃圾渗沥液MBR出水进行电化学试验研究。结果发现,Ti/SnO2SbO3CuO电极具有较高的析氧电位,较其他电极表现出较高的COD去除能力,最佳电流密度为25 mA/cm2,可将垃圾渗沥液MBR出水中COD降至低于100 mg/L,达到《生活垃圾填埋污染控制标准》(GB 16889—2008)表2排放标准。In this paper,Ti/BDD,Ti/SnO2SbO3CuO,Ti/PbO2,Pt/Ti and Ti/RuO2 electrodes were selected to conduct electrochemical experiments on MBR effluent from domestic waste leachate.The results showed that Ti/SnO2 SbO3CuO electrode had higher oxygen evolution potential,higher COD removal ability than other electrodes,and the optimal current density was 25 mA/cm2.The COD in MBR effluent of landfill leachate could be reduced to less than 100 mg/L,which met the discharge standard of Table 2 of"Standard for Pollution Control of Domestic Waste Landfill"(GB 16889—2008).
