At present, volatile petroleum hydrocarbon pollution in soil is still widespread and serious in China. Among the treatment methods for contaminated soil, soil vapor extraction technology is widely used in remediation of volatile petroleum hydrocarbon-contaminated soil due to its simple equipment, easy installation, convenient operation and high remediation efficiency. In this paper, the present situation of volatile organic compounds (VOCs) contaminated by petroleum hydrocarbons is reviewed. The effects of soil permeability, pollutant characteristics, soil moisture content, ambient temperature, and gas extraction flow rate on soil vapor extraction are discussed. Moreover, five different types of soil vapor extraction enhancement technologies, characteristics, research and applications are introduced, and the development prospect of soil remediation industry is presented.
目前，中国土壤中挥发性石油烃污染仍然广泛而严重。在受污染土壤的处理方法中，由于设备简单、安装方便、操作方便、修复效率高，土壤气相抽提技术在挥发性石油烃污染土壤的修复中得到了广泛应用。本文综述了石油烃污染挥发性有机化合物（VOCs）的现状。讨论了土壤渗透率、污染物特性、土壤含水量、环境温度和气体提取流速对土壤气相抽提的影响。此外，还介绍了五种不同类型的土壤气相抽提强化技术的特点、研究和应用，并对土壤修复行业的发展前景进行了展望。
