- Abstract
Magnesium ammonium phosphate by adding magnesium salt and phosphate to ammonia nitrogen landfill leachate,The medicament and ammonia nitrogen landfill leachate Mg2+ PO3- ions in NH4+ after chemical reaction of producing magnesium ammonium phosphate.In the whole reaction process is influenced by pH value,reaction time,reactant ratio etc..The effects of pH,reaction time,reactant ratio and Calcium ions amount on ammonia-nitrogen removal efficiency and the residual concentrations of ammonia-nitrogen have been investigated respectively.The optimum reaction conditions by orthogonal experiment are Mg2+ PO43- NH4+=1.2 1 1, pH=9,t=15min and Ca2+/Mg2+=0.Ammonia-nitrogen removing tests of Laohuchong landfill leachate performed under the optimum conditions,and the best removal efficiency is above of 60%.
