Effect of Dissolved Organic Matter in Simple Landfill Leachate on the Dissolution and Migration of Pb(Ⅱ)

  • 摘要: 为研究简易填埋场垃圾渗滤液DOM(dissolved organic matter, 水溶性有机物)对重金属Pb(Ⅱ)的配位与迁移溶出的影响,运用荧光猝灭分析及柱模拟技术,研究了不同填埋年限(5和10a)简易填埋场垃圾渗滤液DOM与Pb(Ⅱ)的相互作用. 三维荧光猝灭分析表明,填埋10a的垃圾渗滤液DOM紫外区、可见区类富里酸配位荧光基团所占的比例分别比填埋5a的垃圾渗滤液增加了17.68%和7.96%;而配位稳定常数(lg K)则分别降低了10.13%和17.42%. 柱模拟试验结果表明,垃圾渗滤液DOM对土壤中Pb(Ⅱ)的纵向迁移具有促进作用,填埋5和10a的垃圾渗滤液DOM对Pb(Ⅱ)的累计迁移率分别是对照组的2.41和1.98倍. 与填埋5a相比,填埋10a的垃圾渗滤液DOM对Pb(Ⅱ)的溶出能力显著降低,表明随着填埋年限的增加,渗滤液DOM对Pb(Ⅱ)的溶出能力呈降低趋势. 对相同填埋年限的垃圾渗滤液,ρ(DOM)越高,对Pb(Ⅱ)的迁移溶出能力越强;Pb(Ⅱ)的平均迁移量会随着填埋时间的推移逐步降低.
