摘　　要：以MgSO4·7H2O和Na2HPO4·12H2O作为沉淀剂加入到垃圾渗滤液中,形成磷酸铵镁沉淀,可有效去除渗滤液中氨氮含量。最佳反应条件为:pH=9.5、Mg∶N=1.8∶1,P:N=1.8∶1,在此条件下NH3-N去除率达97%,COD的去除率达到20%。MgSO4·7H2O and Na2HPO4·12H2O is used as precipitation drugs,added into landfill leachate,to form MAP precipitation,which is effective to remove ammonia nitrogen in leachate. When pH = 9. 5,Mg∶ N = 1. 8∶ 1 and P∶ N = 1. 8∶ 1,the removal rate of NH3- N and COD can reach 97% and 20% respectively,which is the optimal reaction condition.
