抚顺西露天矿及周边水环境调查与评价

Investigation and evaluation of water environment in Fushun West Open-pit Mine and its surroundings

针对刚刚闭坑的抚顺西露天矿,开展其周边水环境的调查与评价,探清了抚顺西露天矿矿区内地表水、地下水环境质量污染的现状,阐明了矿区地理环境对周围水环境影响的程度。调查结果表明:该矿区地表水主要污染物有高锰酸性指数、COD、BOD5、DO、NH3-N、总磷等6种;地下水主要污染指标有总硬度、溶解性总固体、硫酸盐、NH3-N、Fe、Mn、Na、氯化物、氟化物、耗氧量及石油类等11种,其中铁离子超标率最高,从污染物分布的空间分析,污染源主要分布在汪良舍场、西舍场、东舍场以及西露天矿的北侧和东露天矿的北侧。

We carry out the investigation and evaluation of the surrounding water environment of Fushun West Open-pit Mine,find out the pollution status of surface water and groundwater in the mine area,and reveal the influence degree of geographical environment in the mining area on water environment.The results show that the main pollutants in surface water have six species,permanganate index,COD,BOD5,DO,NH3-N and total phosphorus.In Fushun West Open-pit Mine,groundwater pollution(greater thanⅢclass)indicators mainly have chloride,total hardness,NH3-N,sulfate,total soluble solids,sodium,Fe,manganese,oxygen consumption,fluoride,and oil eleven species,the iron which is highest.From spatial analysis of pollutant distribution,pollution sources are mainly distributed in Wang Liang field,west,east field and north side of Fushun West Open-pit Mine and the north side of Fushun East Open-pit Mine.
