摘　　要： 采用上流式厌氧污泥床处理某垃圾填埋场渗滤液.实验结果表明,在厌氧氨氧化活性稳定后,反应器对氨氮、亚硝氮具有较好的处理效果,氨氮和亚硝氮的平均去除率分别达到98.42%和99.01%,相应的平均容积去除负荷分别为93.64mg.l-1.d-1和127.57mg.l-1.d-1,COD的平均去除率为23.51%,平均容积去除负荷为84.53mg.l-1.d-1.通过GC-MS总共检测出48种主要有机污染物,其中14种有机物的去除率为100%,2种有机物的去除率介于90%和100%之间,7种有机物的去除率介于50%和90%之间,此外还有13种有机物去除率低于50%.反应中亚硝氮和氨氮的去除率比值为1.37,反应器中存在厌氧氨氧化和反硝化的协同作用. Effect of anaerobic ammonium oxidation on landfill leachate had been researched in the paper. It had been demonstrated that well removal effect of NH3-N and NO2-N could be reached in the upflow anaerobic sludge blanket, corresponding to the average removal efficiencies of NH3-N and NO2-N being 98.42% and 99. 01%, together with their average volume removal loads being 93. 64 mg .l^-1.d^-1and 127. 57 mg.l^-1.d^-1, respectively. The mean removal efficiency of COD was only 23.51% during the experimental period. 48 kinds of organic matters had been detected by gas chromatograph-mass spectrometer method. Among of them, removal efficiencies of 14 kinds organic compounds were achieved 100% , removal efficiencies of 2 kinds organic compounds were 90%--100% and the removal efficiencies of 7 kinds organic compounds were 50%--90%. Moreover, there still had 14 kinds organic compounds which removal efficiencies were below 50%. It had been indicated that there had synergistic effect of anaerobic ammonium oxidation and denitrification in the reactor, for the ratio of NO2-N removal to NH3-N removal being 1.37.
