摘    要:用细砂、砂土和粉砂土为材料,通过土柱模拟实验,分别从空间和时间研究不同岩性的土壤对垃圾渗滤液污染晕中污染物衰减的影响。实验初期,砂土和粉砂土对TOC的去除率分别达到96.56%和99.87%,而细砂仅达到62.78%,但3种土壤对NH+4-N的去除率均高达98%以上。实验末期,细砂、砂土和粉砂土对TOC的去除率已分别降至57.79%、65.59%和67.29%;但砂土和粉砂土对NH+4-N去除率仍高达87.38%和90.13%,而细砂自第18天时已被穿透。因此,3种土壤对污染物的衰减能力为粉砂土>砂土>细砂。

关 键 词:岩性  渗滤液  污染晕  衰减

Abstract:Three simulated columns filled with fine sand, sandy soil and fine sandy soil respectively were used to study the impacts of lithological effect on attenuation of pollutants in leachate plume. Results of the experiment indicated that removal of pollutants varied with the different sand and soil, soils (sandy soil and fine sandy soil) being better than fine sand with respect to TOC and NH4+-N removals. In general, the pollutants attenuation ability ranked as: fine sand soil>sandy soil>fine sand.
Keywords:lithology  pollution plume  attenuation
