摘要
原地浸出逐步成为我国铀矿开采的主流工艺,但地浸过程会不可避免的对地下水造成污染。本文对原地浸出地下水修复方法的研究现状做了评述,针对U的迁移机理、微生物还原法、化学还原法、抽出处理法及自然衰减法的应用研究情况做了介绍,最后指出室内实验研究可以掌握修复机理并为数值模拟提供必要的参数,但实验结果的工程应用受尺度问题限制,必须加强室内实验、数值模拟及野外数据的相互验证为地下水修复工程提供科学依据。
Leaching process will inevitably pollute the groundwater with In-situ leaching which has gradually become the mainstream technology of uranium mining in China..This paper reviewed the research status of contaminated groundwater remediation methods of in-situ uranium leaching by introducing the research and application status of the migration mechanism of U,the microbial reduction method,the chemical reduction method,extraction treatment and natural attenuation method.Finally,it indicated that laboratory experiments can inspect the repair mechanism and provide the necessary parameters for numerical simulation.But for the reason of engineering application of the experiment conclusions were limited by scale problem,it needs us to strengthen the mutual verification of laboratory experiments,numerical simulation and field data to provide scientific basis for groundwater remediation engineering.
