某铀矿矿坑水呈酸性(pH3～6),含有一定量的铀、镭及镉、锰、锌等放射性核素和化学有害元素。若不经处理直接排入露天水源及农田,将污染周围环境,给农业和渔业带来损害。为此,该铀矿在铀矿冶设计院、湖南省劳卫所等单位协作下,1971年开始对矿坑水进行了分期处理。首先进行了除铀,继而除镭、镉、锰、锌等有害离子。先后经过数年的努力,终于解决了矿坑水对环境的污染问题。经地方环境保护部门监测确认,该矿排出的矿坑 A mine uranium pit acidic (pH3 ~ 6), contains a certain amount of uranium, radium and cadmium, manganese, zinc and other radionuclides and chemical harmful elements. If untreated directly into the open water and farmland, will pollute the surrounding environment, causing damage to agriculture and fisheries. To this end, the uranium mine in uranium mining and Design Institute, Hunan Province, Labor and other units in collaboration with the mine began in 1971, phased treatment. First, in addition to uranium, followed by addition of radium, cadmium, manganese, zinc and other harmful ions. After several years of hard work, it finally solved the problem of mine water pollution on the environment. The local environmental protection department monitoring confirmed that mine discharge pit
