地下水污染及修复技术的研究浅析

Analysis on Groundwater Pollution and Remediation Technologies

地下水污染主要指人类活动引起的地下水化学成分、物理性质和生物学特性发生改变而使质量下降的现象。目前我国地下水遭受不同程度的污染,受污染面积大,污染源复杂,使得地下水污染修复工作开展困难。综述了地下水污染的类型和国内外常见的地下水污染修复技术,并对在地下水污染修复过程中存在的问题和地下水污染防治未来的发展方向进行展望。

Groundwater pollution mainly refers to the phenomenon of degradation of groundwater quality due to changes in its chemical composition,physical properties and biological characteristics caused by human activities.At present,China’s groundwater suffers from different degrees of pollution,the contaminated area is large and the pollution sources are complex,making it difficult to carry out groundwater pollution remediation work.This paper reviews the types of groundwater pollution and common groundwater pollution remediation technologies at home and abroad,and provides an outlook on the problems existing in the process of groundwater pollution remediation and the future development direction of groundwater pollution prevention and control.
