针对垃圾渗滤液持续时间长、污染严重、地面处理成本高的特点，开展了麦饭石作为渗透性反应墙(PRB)活性材料的可行性研究。通过单因素及改性方法进行了麦饭石对Mn2+和NH4+-N的吸附性能试验。结果表明，麦饭石吸附Mn2+和NH4+-N的最佳操作条件为：pH值7、振荡频率150 r/min、反应时间2 h、粒径0.55~1.7 mm、投加量5 g/100mL，在此条件下，Mn2+和NH4+-N去除率及吸附量分别为42.89%、19.27%和0.066 mg/g、0.223 mg/g；改性麦饭石能够提高吸附速率，但是吸附量降低，选择阜新天然麦饭石作为PRB活性材料进行垃圾渗滤液中Mn2+和NH4+-N的原位处理可行。

According to the characteristics of leachate are long duration, serious pollution and high treatment cost, feasibility study was carried out about medical stone as the PRB materal. Mn2+ andNH4+-N were adsorbed by medical stone through the single factor experiment and modiifed test. The result showed that the optimum environment were: pH value 7, oscillation frequency 150 times per minutes, reaction time 2h, dosing quantity 5g/100mL,best sizes of ifller particles0.55~1.7mm. Under these conditions, the removal rate of Mn2+ andNH4+-N were 42.89%, 19.27% respectively;the adsorption capacity for Mn2+ andNH4+-N were 0.066 mg/g and 0.223 mg/g. Modiifcation is good for adsorption rate, adsorption capacity decreased. So medical stone is the best adsorption material for leachate.
