| Abstract: | 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%. |
