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。
垃圾滲濾液是一種含有高濃度COD和氨氮的汙水。本實驗針對滲濾液的特點，研究瞭燐痠銨鎂沉澱-SBR組閤工藝處理滲濾液的運行狀態。實驗結果錶明：在NH4＋、Mg2＋、PO43-的投配比m（NH4＋∶Mg2＋∶PO43-）為1∶0.4∶0.4的時實驗結果最佳，運行穩定後SBR對CODCr、NH3-N和TP的去除率分彆維持在75％、90％和70％左右。其中， CODCr去除率與活性汙泥有機負荷呈線性關繫，迴歸方程為：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.
