Soil Vapor Extraction Removal of Semi Volatile Organic Compounds in Soil: A Pilot-scale Study

摘要

Semi Volatile Organic Compounds (SVOCs) contamination in soil was a widespread problem in China due to industrial pollutants leak and discharge. A pilot study of SVE and related combination techniques was demonstrated for soil contaminated with SVOCs. A miniaturization SVE system was applied in research and performance of this extraction system was measurement. The results of the field test showed that single SVE treatment has limited effect in SVOCs removal and combination of chemical oxidation with SVE and heating SVE could get a better remediation effect of 89% removal and costs 216RMB/m~3. It is promising to use SVE combination techniques in the SVOCs contaminated soil remediation, through change soil properties or optimize operating parameters, due its good efficient and economical.
