摘　　要：在厌氧复合床反应器中进行了垃圾渗滤液的反硝化/产甲烷的试验.试验结果表明,处理有机物浓度较高的垃圾渗滤液时,反硝化/产甲烷能够在厌氧复合床反应器中实现同步进行.下部的污泥床承担了主要的反硝化任务,当进水COD/NO3-N〉9时,下部污泥床对NO3-N的去除率可达到99%以上.随着进水COD浓度的提高,达到4 000 mg/L以上时,下部污泥床和上部生物膜对COD的去除能力均趋于稳定.下部污泥床稳定在6.0~7.0 g COD/（L.d）;上部生物膜稳定在5.0~6.0 g COD/（L.d）.The landfill leachate treatment test of denitrification/methanogenesis was done on the anaerobic composite bed reactor.Test results show that,denitrification/methanogenesis can simultaneously occur in anaerobic composite bed reactor if there is high concentration of organic matter.The lower sludge bed contributed to the denitrifying progress mainly.When COD/NO3-N is higher than 9,removal rate of NO3-N can reach 99 percent in the lower sludge bed.When the inflow COD reaches 4 000 mg/L,COD removal capacities of upper biofilm and lower sludge bed remain stable,which of the bottom sludge bed is at 6.0~7.0 g COD/（L·d）,and upper biofilm 5.0~6.0 g COD/（L·d）.
