摘要
研究进行了用Mg2 + 、Mn2 + 分别与PO4 3- 作用去除NH4 + N的试验研究 ,探讨其化学反应机理 ,确定了最佳投药比、反应pH和Mg2 + 、Mn2 + 的协同效应 ,并对广州李坑垃圾填埋场渗滤液中NH4 + N进行了处理 ,其中最大NH4 + N去除率达 96 .1 %。
In the paper, the reaction of Mg 2+ .PO 3- 4 or Mn 2+ ,PO 3- 4 with NH + 4 was used to remove NH + 4 N from wastewater, and the optional ration of Me 2+ (Mg 2+ ,Mn 2+ ):NH +:PO 3- 4 and pH for the precipitation reaction and cooperative effect of Mg 2+ , Mn 2+ was determined, the removing of ammonia nitrogen from Likeng Landfill leaching liquor in Guangzhou was tested by the chemical precipitation. The results show maximum removal ratio of NH + 4 N is 96.1%.
