| Abstract: | Soil vapor extraction (SVE) is an acceptable remediation technology for soil contaminated by organic compounds, it holds security, high efficiency and economy properties. Characteristic, status and development of SVE were systematically discussed. Models used to estimate the time needed for a certain decontamination standard were summarized. Major factors that influence remediation time of SVE, including air permeability, water saturation, vapor pressure, air flow rates and environmental temperature were described. The problems and development view of SVE were also discussed. |
