| 摘 要： | 调查了拟建清平水库周围磷矿所排废渣的情况，弄清了废渣堆放量及分布。绵远河４个断面连续５个月水质监测的数据表明了该地废渣降雨淋溶对河流水质带来了严重的危害。河流沉积物分析表明，由于受磷矿渣的影响，沉积物中Ｃｄ、Ｐｂ、Ｐ、Ｆ超标严重，总磷含量平均高达９８９２ｍｇ／ｋｇ。若不控制磷矿废渣，新建的清平水库必将发生富营养化。

| Abstract: | The discharge of phosphorus mine tailling from the mines around the proposed Qingping Reservoir has been investigated, the investigation involes the quantity and distribution of the mine tailling. The successive five months water quality monitoring data of four cross section of Mianyuan River indicated that serious water pollution has been caused by eluvial runoff from phosphorus mine tailling piles. The results of river sediment sample analyses showed that with the influence of the tailling, the Cd, Pb, P and F contents of the sediments were all heavily exceeding the standards. The average phosphorus concentration was 9892 mg/kg. It has been concluded that the mine tailling must be well managed and its pollution must be well controlled, otherwise the new built Qingping Reservoir will have to face the problem of eutrophication. |
