【 摘 要 】

An experimental model is established by simulating SVE to collect the contaminated soil samples near the wells of Dongying Dongxin oil production plant in Shandong Province as a polluted medium, ethanol, n-propanol, n-butanol as the target pollutant, the controlling variable method and gas chromatographic technique were used to investigate the effect of volatile pollutant species on the removal efficiency of SVE, found that for a single pollutant system, under the same SVE conditions, the removal rate of ethanol after 48h was up to 91.6%, n-propanol 73.5%, n-butanol 66.1%; under the same SVE conditions, the removal rate of ethanol after 48h was up to 88%, n-propanol 78% in the ethanol-n-propanol system, ethanol 84.1%, and n-propanol 64.9% in the ethanol-n-butanol system. It provides a basic reference for the remediation of contaminated soil in the field.
