| 摘 要： | 采用序批次吸附试验,研究了不同填埋年限垃圾的渗滤液在土壤中的吸附影响。结果表明,对来自不同填埋年限的垃圾渗滤液在2种土壤上的吸附等温线采用“原始质量吸附方程”拟合表现出良好的相关性(r2>0.96),其吸附量与土壤中有机碳含量、粘粒含量及电荷密度与种类等有关。在垃圾渗滤液的同一初始浓度下,红壤对垃圾渗滤液的平均净吸附量是潮土的1.74倍。填埋年限较长的垃圾渗滤液与土壤有较高的亲和力。

| Abstract: | Batch adsorption experiments were conducted to measure the sorption of landfill-leachate in soils derived from different landfill sites.The results showed that sorption isotherm of different landfill-leachate in the soils were fit for the initial mass isotherm and,well in linear correlation.Under identical concentration,average net adsorption of landfill-leachate in the acidic soil was 1.74 times of that in the calcareous,and landfill-leachte having higher amounts of larger-molecular-weight or hydrophobic fractions would be preferentially adsorbed by soils. |
