摘　　要：垃圾渗滤液是一种含有高浓度COD和氨氮的污水。本实验针对渗滤液的特点,研究了磷酸铵镁沉淀-SBR组合工艺处理渗滤液的运行状态。实验结果表明:在NH4+、Mg2+、PO43-的投配比m(NH4+∶Mg2+∶PO43-)为1∶0.4∶0.4的时实验结果最佳,运行稳定后SBR对CODCr、NH3-N和TP的去除率分别维持在75%、90%和70%左右。其中,CODCr去除率与活性污泥有机负荷呈线性关系,回归方程为:η=-233.29Fw+169.17。Landfill leachate is a kind of wastewater containing high concentration of COD and ammonia nitrogen. For the characteristics of the landfill leachate, this test studies the operating state of MAP precipitation-SBR composite process of treating the leachate. The test results show that under the optimal conditions that the ratio of m（NH4＋∶Mg2＋∶PO43-） is 1∶0.4∶0.4, the removal rate of the SBR system to CODCr, NH3-N and TP are remained at 75%, 90%and 70%respectively after running steadily. And among them, the removal rate of CODCr has a linear relation with activated sludge’s organic load with the regression equation ofη=-233.29Fw＋169.17.
