摘要
本研究以垃圾渗滤液为研究对象,探讨了pH值、Mg/N、P/N摩尔比对磷酸铵镁生成的影响。实验结果表明,当垃圾渗滤液中的NH+4浓度为1670mg·L-1,调节水样pH值为9.5,Mg/N、P/N摩尔比分别为1.0、1.1,有87.5%的NH4+-N转化为磷酸铵镁。
A study was carried out with landfill leachate. The effects on magnesium-ammonium phosphate formation of pH value, Mg/N and P/N mole ratios were investigated. The results indicated that 87.5% percent of NH4＋ -N in landfill leachate containing 1670mg.L-1 NH4＋-N was translated into magnesium-ammonium phosphate under 9.5 of pH value, 1.0 and 1.1 mole ratios of Mg/N and P/N respectively.
