摘　　要：地下水石油类污染因其污染普遍、危害性巨大、去除困难以及治理费用昂贵而受到广泛关注。原位曝气修复技术(AS)以低成本、修复效率高、操作简便等优势近些年来发展迅速。文章综述了地下水石油类污染现状,阐述了AS修复地下水石油类污染物原理,从曝气流型、组分传质以及生物扰动降解等方面深入探讨了注入气体运移方式及分布范围的影响因素,污染物的传质行为及质量去除机制,生物降解及监测手段等,总结了AS修复的研究进展。指出了当前AS修复技术在非均质介质的理论模型以及生物降解作用定量化表征方面存在的问题,并就未来强化修复实现多技术协同联用结合新兴监测分析技术进行了展望,以期为AS修复技术进一步的研究和应用推广提供参考依据。Petroleum pollution in groundwater has drawn a wide attention due to its universality,harmfulness,difficult removal and expensive treatment.The in-situ air sparging remediation has developed rapidly in recent years with the increasing realization of its advantages,including the low cost,a high efficiency and an uncomplicated operability.This paper mainly concludes the current situation of petroleum pollution in groundwater and illustrates the mechanism of air sparging.In detail,based on the analysis of the air flow pattern,mass transfer and biodegradation of AS technology,the influence factors for migration mode and distribution range of injected gas,mass transfer and quality removal mechanism of pollutants,biodegradation and its monitoring methods are discussed,and the research progress of this technique is summerized.It is necessary to point out the existing problems in the theoretical model for the heterogeneous media and the quantitative characterization of biodegradation.In addition,this paper analyzes the prospect of the enhanced remediation to realize multi-technology combined with the emerging monitoring technology,which can be a guidance for a further improvement,application and extension for the in-situ air sparging remediation.
