摘　　要：空气喷射 (airsparging)被认为是修复由可挥发性有机物污染的饱和土壤和地下水的一种有效新技术。介绍了空气喷射技术的现场应用与研究现状 ,讨论了空气喷射技术的原理和各种影响因素 ,说明了其对于饱和土壤中有氧生物降解的促进作用 ,分析了空气喷射技术的应用前景。Air sparging is a efficient technique for the remediation of satrurated soils and groundwater that have been contaminated with volatile organic compounds. This paper focuses on the applications and development of air sparging. The mass transport mechanisms and various factors which will improve air sparging performance are discussed as well. It is recommended that air sparging stimulated the aerobic degradation in saturated soils and groundwater. Moreover, air sparging technology is simple to use, and can lend considerable insight to remediation of saturated soils and groundwater.
