摘要
分析了垃圾填埋场渗滤液的特点及水质影响因素,叙述了磷酸铵镁沉淀法(MAP法)去除垃圾渗滤液中氨氮的基本原理,探讨了MAP法在不同搅拌时间、不同Mg∶N∶P和不同搅拌速度下对氨氮的去除效果,确定MAP法的最优操作条件为:反应时间45 min,搅拌速度160 r/min,Mg∶N∶P(物质的量比)为1.8∶1∶0.8。
The characteristics of old landfill leachate is analyzed and the principle of the removal method ( MAP precipitation) for NH3 - N in landfill leachate is narrated. The removal of ammonia is disscussed under different mixing time,different Mg : N : P( the amount - of - substance ratio) and different stirring speeds. MAP method for the optimal operating conditions:reaction time 45 min, stirring speed of 160 r/ min,Mg: N: Pis 1.8: 1:0.8.
