地下水污染修复技术研究进展

Research Progress on Remediation Technologies of Groundwater Pollution

由于工农业的快速发展,中国地下水污染现状不断加剧。根据生态文明建设要求,了解和掌握地下水污染修复技术方法及原理,对于建设美丽中国具有重要意义。纵观国内外近几十年地下水污染修复技术成效及发展历程,结合中国区域特征及水文地质等概况,分析了地下水污染来源,总结概括出抽出处理、多相抽提、原位曝气、循环井、渗透性反应墙、原位化学等地下水污染修复技术原理及优缺点,并针对目前修复技术的局限性,提出些许建议,以期为今后地下水污染防治及修复提供科学参考。

Groundwater pollution in China is increasing due to the rapid development of industry and agriculture.According to the requirements of ecological civilization construction,understanding the principles and methods of groundwater pollution restoration is of great significance for building a beautiful China.Throughout the achievements and development process of groundwater pollution remediation technology at home and abroad in recent decades,this paper analyzed the sources of groundwater pollution based on the present situation of groundwater and combined with Chinese regional characteristics and hydrogeology.It summarized the principles,advantages and disadvantages of extraction treatment,multi-phase extraction,in-situ air sparging,circulation well,permeable reactive barrier and in-situ chemical remediation technologies.Some suggestions in view of the limitations of the current remediation technology were put forward in order to provide scientific reference for the prevention and remediation of groundwater pollution in the future.
