摘要
以毕节市五个具有代表性的煤矿废水为样本,分析了矿井废水中铁、锰、铜、锌、铅、镉几种重金属成分及其含量,为毕节市在环境保护中对煤矿废水监测和煤矿周边土壤污染调查、治理提供数据支持。结果表明,该地区煤矿废水主要含有铁、锰、铅三种重金属。其中铁最高浓度为45.5352 mg·L-1,锰最高浓度为2.6736 mg·L-1,铅最高浓度为0.0526 mg·L-1。矿井废水中铁含量较高时,伴有锰元素且含量也较高。在煤矿废水监控和周边土壤污染调查、治理时应以铁、锰、铅三种重金属为主要对象。
The composition and content of heavy metals in mine waste water, such as Fe, Mn,Cu, Zn, Pb, Cd, were analyzed, which used five representative samples of coal mine waste water in Bijie city. The research will provide data support for monitoring mine waste water and investigating and governing surrounding soil pollution of coal mine during the environmental protection process in Bijie.The result indicated that the coal mine waste water in this area mainly contained Fe, Mn and Pb, and their maximum concentration were 45.5352mg·L-1, 2.6736 mg·L-1, 0.0526 mg·L-1, respectively. In addition, when the content of Fe in mine waste water was high, the content of Mn would also be at a high level. In conclusion,the monitoring of mine waste water and the researching and the governing of surrounding soil pollution of coal mine should focus on three heavy metals, Fe, Mn and Pb.
