摘要:
为了解鱼洞河流域废弃煤矿矿井水外排对水环境的影响,测定了河流水体及矿井水的pH值,SO42-及重金属(Fe,Mn,Cu,Cd,Pb,Zn)浓度和底泥中重金属(Fe,Mn,Cu,Cd,Pb,Zn)含量。结果表明:矿井水呈酸性,Fe,Mn,Zn超出当地矿井水排放标准。鱼洞河流域中河流水体pH值,SO42-,Fe,Mn和Cd浓度超出地表水水源地相关标准限值,各河段上游水体及重安江水质较好,综合污染指数法评价结果为无污染,受矿井水排入的影响,各河段下游水体pH值,SO42-,Fe,Mn明显超标,评价结果为重度污染。相关性分析及主成分分析结果表明:河流水体主要受矿井水及自然成因两方面影响。鱼洞河流域底泥中Cu,Mn未超出贵州省土壤背景值,而Fe,Cd,Pb,Zn均存在一定程度的超标,地累积指数法评价结果表明:鱼洞河流域河流底泥受Cd,Pb,Fe的轻微污染,矿井排水口底泥受Fe中度至强污染。
Abstract:
In order to understand the impact of the mine drainage in the abandoned mine of the Yudong River Basin on the water environment, the pH value, the concentrations of SO42- and heavy metals (Fe, Mn, Cu, Cd, Pb, Zn) of the river water and mine water, and the contents of heavy metals (Fe, Mn, Cu, Cd, Pb, Zn) in the sediment were determined. The results show that the mine water is acidic, the concentrations of Fe, Mn and Zn exceed the local mine water discharge standards; the pH value, concentrations of SO42-, Fe, Mn and Cd in river water in the Yudong River Basin exceed the relevant standard limits of surface water sources; the water quality of the upstream river of the Yudong River Basin and the Chongan River are good, the results from the comprehensive pollution index method indicate that the water is not polluted; due to the discharge of mine water, the pH value, concentrations of SO42-, Fe and Mn of the water of downstream river obviously exceed the standard limit of surface water sources, and the evaluation result indicates that water of downstream river is severely polluted. Correlation analysis and principal component analysis show that river water is mainly affected by mine water and natural factors. The contents of Cu and Mn in the sediments do not exceed the soil background values of Guizhou Province, while the contents of Fe, Cd, Pb and Zn exceed the standard. The evaluation results from the cumulative accumulation index method show that the river sediment in the Yudong River Basin is slightly polluted by Cd, Pb and Fe, the sediment of the mine drain is moderately or strongly polluted by Fe.
