| 摘要： | 1,4-Dioxane, a cyclic diether and an additive in the chlorinated solvent 1,1,1-trichloroethane, has proven to be a persistent groundwatercontaminant. Conventional soil vapor extraction (SVE) can remove some 1,4-dioxane, but a substantial residual source is left behind causinglong-term groundwater contamination. Although 1,4-dioxanes vapor pressure in the range of trichloroethylene or benzene, it is totally misciblein water soluble. As a result, 1,4-dioxane becomes sequestered in vadose zone pore water which serves as a long-term source of groundwatercontamination. Extreme soil vapor extraction (XSVE), an enhancement of SVE, specifically addresses 1,4-dioxane-contaminated soil byincorporating enhancements such as decreased infiltration, increased air flow, focused vapor extraction, and injection of heated air. |
