摘　　要：针对垃圾填埋渗滤液水质随填埋时间的延长而日渐恶化的特点,设计前置MAPSBBR耦合工艺处理早、晚期垃圾渗滤液。试验结果表明,在最佳运行条件下,对早期垃圾渗滤液NH+4N的总去除率为99.6%,CODCr的总去除率为94.0%;对晚期垃圾渗滤液NH+4N的总去除率为99.3%,CODCr,的总去除率为87.1%。前置MAPSBBR耦合工艺适用于各期垃圾渗滤液的处理。Based on the urban landfill leachates characteristic of the daily variational water quality along with the landfill process, the composite process of MAP-SBBR was used to treat the early landfill leachate and the late landfill leachate.The test results showed that under the optimum running conditions of the MAP and SBBR,the total removal rates of NH_4-N and COD_ Cr were 99.6% and 94.0% respectively for the early landfill leachate;and the total removal rates of NH_4-N and COD_ Cr were 99.3% and 87.1% respectively for the late landfill leachate.MAP-SBBR process was suitable for the treatment of every period landfill leachate.
