国外地浸铀矿山地下水修复技术

Groundwater Restoration Technologies for ISL Uranium Mine Abroad

对ISL采铀的环境影响认识不足,研究投入不够;再加上地下水修复技术成熟度低、治理周期长、修复效果具有不确定性等因素,为开展地浸铀矿山地下水修复工作带来一定影响。为了消除或缓解ISL采铀对饮用水源或邻近地下水的潜在影响,一些国家制定相关政策,并针对不同的地浸工艺和地质环境条件,分别采取自然衰减、抽水处理回注、生物修复等地下水修复技术,取得了较好的治理效果。笔者对部分国外地浸铀矿山地下水修复技术进行了对比分析,旨在为中国地浸铀矿山地下水修复技术研究与工程实施提供参考。

Due to the potential impact of ISL mining on groundwater environment is poorly understood,relevant research is not enough,at the same time,also because of the factors as the low maturity of groundwater remediation technologies and the uncertainty of remediation effects,this work has been affected.As a result,some countries require groundwater to be recovered after extraction to eliminate or attenuate the potential impacts on drinking water sources or adjacent groundwater,making some relevant policies on it,and implementing technologies such as natural attenuation,pump and treat,biology remediation respectively according to different leaching process and geology conditions of each site,some fundamental restoration results have been acquired.In this paper,the groundwater remediation techniques and methods of some foreign in-situ leaching uranium mines are introduced,in order to provide reference for the research and engineering implementation of restoration technologies for in-situ leaching mine in China.
