The Study on Repairing Groundwater Contamination Polluted by Coal Gangue Leachate by Means of Lishi Loess

  • 摘要: 为以较好的技术手段和较低的经济成本治理煤矸石淋滤液、矿坑废水对地下水的污染,通过土柱淋滤试验、PRB (permeable reactive barrier)模拟试验以及场地修复试验,对煤矸石淋滤液中重金属(Zn、Mn、Pb、Cr、Cu、Cd、Hg)及As的吸附性进行了研究. 土柱淋滤试验结果表明:离石黄土(粒径0.05~0.10mm)、亚砂土(粒径0.05~0.10mm)和细沙(粒径>0.10~0.25mm)对煤矸石淋滤液中的重金属(Zn、Mn、Pb、Cr、Cu、Cd、Hg)及As的吸附能力为离石黄土>亚砂土>细沙,其中离石黄土对As的分配系数为2.26L/kg.模拟槽试验表明,在地下水流速为0.20m/d、m(煤矸石):m(离石黄土)分别为5和7的情况下,淋滤液中的As能够全部被黄土墙吸附;m(煤矸石):m(离石黄土)为10时,部分As透过黄土墙向下游迁移. 5个月的场地修复试验表明,利用离石黄土作为PRB的吸附材料能够较好地去除地下水中的重金属(Zn、Mn、Pb、Cr、Cu、Cd、Hg)和As,厚约0.5m的离石黄土墙对被煤矸石淋滤液污染的地下水中Cr的去除率最高,达到70.97%,对Pb的去除率最低,为43.14%.
