某铀矿尾矿库废水处理工艺研究

Waste water treatment technique for a uranium tailings pond

分析某铀矿尾矿库废水组成和主要污染因子,通过试验研究,确定了处理该尾矿库废水的工艺流程,即石灰乳中和-锰砂吸附废水处理工艺。经处理,废水中铀、镭、锰、氟、pH值均达到排放标准。

Compositions of waste water from a uranium tailings pond and main pollution factors were analyzed. A method of treating the waste water was determined through experiments, that is, neutra-lization with milk of lime-adsorption with manganese sand method, and the waste water was treated hy the method. Contents of U,Ra and Mn, and pH value in the treated waste water meet the national discharge standard.
