摘要
由于腐蚀、地震、长期使用维护不力等原因会造成地下储油罐油品的泄漏,形成土壤和地下水的污染。本文概述了地下储油罐污染的工程修复技术,主要包括有土壤气相抽提、生物通风、生物堆制处理法、土壤耕作法、地下水曝气、生物曝气、地下水原位生物修复和双相抽提,并给出了各种技术的简单流程图和适用条件,指出了各自的优缺点。
Leakage of petroleum products from storage tanks, resulting from corrosion, lack of proper maintenance or earthquake often pollutes soil and groundwater. Engineering techniques for remedying polluted environment around the underground storage tank （UST） sites, were discussed, including soil gas extraction, bio-venting, bio-composting, soil tilling, sparging of groundwater, bio-sparging, in-situ bio-remediation of groundwater and dual-phase extraction. Besides, a simple flow chart, application range, advantages and disadvantages of each technology were presented in this paper.
