研究以粉煤灰为晶种，采用鸟粪石法预处理100,mL 垃圾渗滤液的最佳条件．结果表明，当 pH＝7.5， n(Mg2+)∶n(NH+4)∶n(34PO -)＝1.35∶1∶1.2，加入2,g粉煤灰作为晶种，在室温下搅拌反应20,min，垃圾渗滤液中氨氮的去除效果最好．%The best pretreatment conditions of 100,mL landfill leachate were studied using struvite precipitation with fly ash as the seed crystal. The result demonstrated that the best treatment conditions were pH value was 7.5,n(Mg2+)∶n(NH+4 )∶n( 34PO -)=1.35∶1∶1.2,the dosage of fly ash was 2,g,and the time for the stirring reaction was 20,min at room tempera-ture.
