摘　　要：该文采用新型生物膜反应器系统对某生活垃圾填埋场渗滤液进行小型现场处理试验。结果表明，当平均温度为15℃时，采用该新型生物膜反应器在4~5d内即可培养出一定厚度的驯化微生物膜并开始稳定地降解污水，各主要污染物指标的降解率均在95％以上，不使用高价的反渗透或纳滤系统即能稳定地达到国家垃圾渗滤液污水处理排放标准。该系统流程简洁、操作简单、工艺先进、无污泥产生、运行成本低，可应用于垃圾渗滤液等含高浓度难降解有机物污水处理，是有发展潜力的新型工艺技术。A new type of membrane bioreactor was used to treat leachate in this paper. The result shows that after 4-5 days＇ bacterial domestication, a suitable thickness of the biofilm is formed on the surface of the membrane when average temperature is 15 ℃, and the degradation rates of the major pollutants are more than 95 %, which can stably meet national discharge standards for landfill leachate without using expensive RO/NF process. With simple processes, easy operation, advanced technology, no sludge produced and low operation costs, the new type of membrane bioreactor can be applied to treat landfill leachate and other wastewater containing high concentration and refractory organic matters, which is a potential new technology.
