地下水污染原位曝气修复强化技术研究进展

Research Progress of In-Situ Groundwater Remediation by Enhanced Aeration

结合近些年来国内外地下水原位曝气修复强化技术的试验研究和理论分析成果,对目前存在的地下水原位曝气修复强化技术进行了归纳总结,分析了8种不同地下水曝气强化技术的作用机理,介绍了相应技术的研究成果。另外通过总结其不同适用场景和对象,进行了性能和适用性比较。今后可通过加强强化技术的工程应用、多元化均衡发展各项技术以及联用不同强化技术,提高地下水曝气修复效果。

Based on the in-situ strengthening air sparging practices and theoretical analysis of groundwater at home and abroad in recent years,a comprehensive review is made on the existing in-situ strengthening air sparging.Mechanism of action and research achievement of different in-situ strengthening air sparging are shown in this review.In addition,the characteristic of these technologies are compared and evaluated,the development trends of relevant research is elucidated at last.In the future,the effect of groundwater aeration restoration can be improved by strengthening the engineering application of reinforcement technology,developing various technologies in a diversified and balanced way,and combining different reinforcement technologies.
