摘要
煤炭中含有多种痕量元素,这些痕量元素随着煤炭的采掘、煤矸石的堆放、洗煤废水的排放等过程进入环境。研究这些元素与环境之间相关关系及迁移速度对污染源调查及污染物防治具有重要的意义。在分别对六盘水市大河边、那罗、大湾、老鹰山、汪家寨等5个矿区煤炭及矿区废水中Li、Be、Cr等37种痕量元素分析的基础上,将这37种痕量元素的关系分为关联性强、较强和弱3种,其中关联性强的痕量元素迁移能力由强到弱依次是Zn、Cr、Be、Cd、Cu、Gd、Sm、Ho、Yb等9种。
Coal contained many trace elements. The elements were released into environment and effected environment in the processing of min ing and using coal. In the trace elements, it was very important to research the concentration law of these elements for research removing process into environment and administer measure of them. Based on the trace elements contents analysis of the coal and waste water, for example Li, Be, Cr, in the Daheban, Naluo, Dawan, Laoyingshan and Wangjazhai Mining Area in Liupanshui City in this paper. And divided the relation between 37 kinds of trace elements in the coal well waste water into three kinds such as strong, related strong and related weak, then arranged in an order the ability of moving according to Ki in every kind. Among them strong trace element moved ability sequentially from strong to being weak was： Zn, Cr, Be, Cd, Cu, Gd, Sm, Ho, Yb.
