abstract:

Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, 2012). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase contamination at extraction wells.

抽提

地下气流的研究在土壤气相抽提（Soil Vapor Extraction）技术中发挥着重要的作用，如去除非饱和带土壤中的挥发性有机化合物（VOCs），量化污染物自然衰减效率等。

土壤气相抽提法

...多发达国家已明文规定,对受VOCs污染的土壤必须进行妥善处置,以保证生物和环境的安全[3]。土壤气相抽提法(Soil Vapor Extraction,SVE)是一种向污染区域通入新鲜空气,将VOCs从土壤中解吸至空气流并引至地面上处理的原位技术[5]。
