摘　　要：矿化垃圾细料中含有经渗滤液长期驯化获得的优势微生物,是很好的渗滤液处理生物介质。在北京阿苏卫垃圾填埋场室外进行了矿化垃圾生物反应床处理渗滤液的研究,结果表明:二级矿化垃圾生物反应床对垃圾渗滤液具有良好且稳定的处理效果,并对渗滤液中污染物浓度的变化具有较好的适应能力。在水力负荷为40L/(m3·d),布水时间为2h/d的条件下,COD和氨氮进水平均浓度分别为10992mg/L和1977mg/L,经过二级矿化垃圾生物反应床处理以后,出水平均浓度达到1001mg/L和23.2mg/L左右,去除率分别为90.9%和98.9%。The aged refuse used was found to have large amount of highly activated microbial community and could be used as a substrate for bioreactor. The experiment of treating leachate using secondary aged refuse bioreactors was done in Beijing A-su-wei waste landfill site. It showed that secondary aged refuse bioreactors had excellent and steady removal ability and could adapt to fluctuant leachate admirably. The average concentrations of COD and NH3-N in inflow were 10992 mg/L and 1977 mg/L. When the hydraulic load was 40 L/（m^3·d） and loading time was 2 h/d, the average removal rates of COD and NH3-N were 90.9% and 98.9% respectively by the treatment of the system. The average concentrations of COD and NHa-N in treated effluent were about 1001 mg/L and 23.2 mg/L.
