| Abstract: | We described the principle of NH3 -N removal method in landfill leachate and analyzed the NH3 -N removal effect in MAP precipitation. At the same time, we contrasted the NH3-N removal effect about different magnesium compound and different reaction time. The results indicated that it had high NH3-N removal effort and low heavy metals content in MAP precipitation, and magnesia had more advantages than magnesium chloride for NH3-N removal. |
