摘要: 气相抽提技术(SVE)是一种安全、经济、高效的有机污染土壤原位修复技术。介绍了SVE的系统组成、修复原理、适用范围及成本,综述了SVE修复石油类污染土壤的研究进展,讨论了SVE效率的影响因素和3种SVE强化技术,并分析了目前SVE技术存在的问题及未来研究方向。Abstract: Soil vapor extraction ( SVE) is a safe,economical and effective in-situate rehabilitating technology for soil contaminated by organic chemicals. The system composition,principles,application range and cost of SVE technology are introduced in this paper. The research progress on rehabilitating oil contaminated soil by SVE is reviewed. Then,major influencing factors on remediation efficiency of SVE and three types of enhanced SVE technologies are discussed. In addition, the existing problems and the research directions of SVE for future are analyzed.
