摘　　要：主要通过静态试验研究了平煤集团十二矿矸石的静态溶出特征和改性土壤对矸石浸溶液中主要污染因子吸附特征;结果表明,煤矸石浸泡液中主要污染因子为SO42-、F-、重金属Mn;改性土壤对SO42-、F-及重金属Mn等污染因子的吸附等温式分别符合Temkin等温式、Freundlich等温式和Freundlich等温式,饱和吸附量分别为14.80 mg/g、0.085 mg/g和0.0087 mg/g;主要发生了配位吸附等专性吸附,吸附稳定性高,不易解吸。Thisarticlehasmainly studiedthestaticdiffluencecharacteristicand theadsorptioncharacteristicof modified soil to themain pollution factorsof gangues leachingby the static tests in the 12th Mineof thePingMei Group.
