摘　　要：本文研究了离子型稀土矿山开采对环境水质的影响。认为,如果废矿液得到良好的闭路循环,对水质的影响主要来自废渣。废渣淋滤水将工艺过程引入的化学物质及尾矿中金属离子带入水体,其中氨氮、亚硝酸盐氮、铅、镉应引起重视。稀土含量在水流中高于一般江河水10~4倍,应制定稀土的环境水质标准。After studying the effects of exploiting ion—absorption rare earth deposit on water enviroment, we concluded that the influence on water quality resulted mainly from the slag if waste mineral water recycles in an insulated system, Leaching water from mineral residue brings metal ions in chemicals and tailings introduced by the exploiting process into natural water. Among these metal ions , NH_3—N, NO_2^-—N, Pb^(2+)and Cd^(2+)should arouse our attention. It's estimated the rare earth in the water of mining area is 10~4 times higher than that in rivers and oceans. We suggest the necessity of formulating a water quality standard for rare earth content in our water enviroment.
