Study on Influencing Factors on Removal of Diesel Oil from Unsaturated Zone by Soil Vapor Extraction
This paper deals with the influencing factors on removal of diesel oil from by soil vapor extraction (SVE) method. A series of one-dimensional column experiments were conducted to study the influencing factors for SVE method, the factors included extracted vapor flow rate,water content and the concentration of the contaminant. The results indicated that: (1) the increase of vapor flow rate led to higher contaminant removal efficiency,but the increment of removal was not significant at higher flow rate levels;(2) the moisture content is 12% coarse sand elimination rate is bigger than 1% coarse sand;(3) the soil index of oil is higher, the extraction time to be longer, it is not suitable processes with SVE that the diesel oil density is excessively low.
