Abstract

Soil vapor extraction (SVE) has been one of the most widely used technologies for remediation of volatile organic compound contaminated sites. However, it is found that various environment factors may have quite different influence on the final remediation effect. In order to learn the influencing factors which affect the removal efficiency of toluene-contaminated sandy soils by SVE method, a series of one-dimensional SVE column tests were conducted. The factors such as grain size, air flow rate and water content were investigated separately. The results indicate that: (1) grain size has a great influence on toluene removal efficiency. The finer the sand is, the lower the removal rate will be; (2) increasing the vapor flow rate will lead to higher contaminant removal efficiency, but the increment of remediation efficiency was not significant at higher flow rate levels; (3) At low water content level, the increase of water content will lead to the decrease of contaminant removal efficiency.
