| 摘 要： | 本试验采用磷酸铵镁沉淀法（MAP）处理垃圾渗滤液中的高浓度氨氮,采用MgCl2.6H2O和Na2HPO4.12H2O为沉淀剂,研究了该方法脱氮的主要影响因素并得出了最佳处理条件,即在室温条件时,pH值为10～10.5、反应摩尔比n（Mg2＋）：n（NH4＋）：n（PO43-）为1.2：1.0：0.9时,对于本试验中的垃圾渗滤液来说,为最佳反应条件,对氨氮的去除率可达到97%以上,达到国家杂用水水质标准中对氨氮的要求。

| Abstract: | MAP precipitation method applied to high concentration ammonia nitrogen wastewater.In this experiment landfill leachate is the research object,MgCl2·6H2O and Na2HPO4·12H2O as a precipitating agent.The optimal technological conditions for the high concentration ammonia nitrogen wastewater treatment were as obtained follows： pH value,10~10.5,reaction mole ratio n（Mg2＋）：n（NH4＋）：n（PO43-）,1.2：1.0：0.9;under the condition of the optimal conditions,the ammonia nitrogen removal rate reached to 97% as the concentration ammonia nitrogen was more than 1000mg/l. |
