地下水污染修复技术研究进展

Progress in groundwater remediation technologies

结合近几年来世界上地下水污染修复技术的研究现状以及各技术在实践中的应用情况,主要介绍了实践应用中地下水污染修复技术的三种较为典型的处理技术,即异位修复技术、监测自然衰减技术、原位修复技术。然后重点总结了抽出处理、可渗透反应墙、地下水曝气、原位生物修复等技术的最新研究进展、技术修复机理、修复对象和适用特点,为地下水修复技术的现场实践提供了理论依据。最后还对地下水污染修复技术的发展方法进行了初步的展望,提出了地下水修复技术便于野外实践的有利的发展方向。

According to the present research status of groundwater remediation technology in the world and the application of the technology in practice,three typical groundwater remediation treatment technologies were discussed,i.e.ex-situ remediation technology,monitoring natural attenuation technology,and in-situ remediation technology.And it introduces the new progress,remedy mechanisms,application conditions and technology characteristics of the pump and treat,permeable reactive barrier,air sparging and in-itu bioremediation technology respectively,which provide the theoretical basis for on-site groundwater remediation.Finally,the developing direction of groundwater remediation technologies were prospected,and the favorable development direction of the field practice are proposed.
