| 摘 要： | MAP法处理垃圾渗滤液,以Na2HPO4·12H2O和MgSO4·7H2O为试验药剂对垃圾渗滤液中高氨氮进行处理,以氨氮作为考察指标,根据单因素试验确定其最佳的工艺条件.试验研究表明:在室温条件下,pH=8.5、M矿∶NH4+∶PO43-的最佳物质摩尔投配比为1.3∶1∶1.2、反应时间20 min、对垃圾渗滤液中的氨氮去除率达到94％,为后续处理奠定了良好的基础.

| Abstract: | During treatment of landfill leachate by MAP method,Na2HPO4 · 12H2O and MgSO4 · 7H2O were used as reagents to treat high concentration ammonia-nitrogen in landfill leachate;taking ammonia-nitrogen concentration as the indicator,the best process conditions were determined by single-factor test.The results show that at room temperature,pH=8.5,Mg2+︰NH4+︰PO43-=1.3︰1︰1.2,reaction time 20 min,removal rate of ammonia-nitrogen in landfill leachate reaches to 94%,which can lay a good foundation for subsequent process. |
