摘　　要：针对某铀尾矿库废水中锰质量浓度、镭活度浓度超标的问题,提出采用碱法曝气-锰砂过滤的工艺除锰除镭.介绍该工艺流程及其在该尾矿库废水处理中的应用.运行结果表明：经该工艺处理后,废水中的锰质量浓度为0.7～1.3 mg/L,镭活度浓度为0.36～0.70 Bq/L,达到排放标准;该废水处理工艺运行稳定,管理方便,但处理费用高,有待进一步研究.Aimed at high manganese and radium concentrations in the effluent of a uranium tailing pond,a process of removing manganese and radium by using aeration and manganese sand filtering method was presented.The process flow and the application of the process in the waster water treatment of the tailing pond were introduced.The run results showed that the manganese and radium concentrations in the treated waster water were in the range of 0.7-1.3 mg/L and 0.36-0.70 Bq/L respectively,and the treated waster water has reached the discharge standard.The process was stable and easy to manage,but its running cost was high.
