摘要
利用拉拉铜矿矿区水环境调查和水质监测资料,依据国家《地表水环境质量标准》(GB3838-2002),采用模糊数学方法对矿区水环境质量进行了综合评价,认为除尾矿水、生活污水极严重污染(Ⅴ类)外,其他水属清洁(Ⅰ类);同时筛选出主要污染因子为来自尾矿水中的Cu,Pb,Zn,Cd和生活污水中的总氮、总磷,进一步探讨了污染物可能造成的环境危害。提出对泄漏的尾矿水可通过吸附、沉淀,除去金属毒物;对生活污水可通过离子交换法和吸附法除氮、除磷,同时还应对矿山水环境加强监管的措施。
The Lala copper mine in Huili county is the biggest one in Sichuan at present. According to ＂ Environmental Quality Standards for Surface Water ＂ （GB 3838-2002）. data concerned with the mine are collected and used to make synthetic evaluation of its water environment quality with the fuzzy mathematic method. In conclusion, the tailing water and sanitary sewage are the seriously polluted water （V kind）, and the others are clean （Ⅰ kind）. Cu, Pb, Zn, Cd from tailing water and total nitrogen and phosphorus from sanitary sewage are regarded as the main pollutants. The possible harm was discussed further. The metal poison in tailing water can be eliminated by adsorbing and precipitating, the total nitrogen and phosphorus in sanitary sewage can be eliminated by ionic exchange technique and adsorption, and the water environment should be strictly supervised and managed.
