摘要
有色金属工业在经济和社会发展以及国防科技工业等方面发挥着重要作用,而有色金属矿山选矿废水有效处理对有色金属行业稳定持续发展有着不可或缺的作用。介绍了有色金属矿山选矿废水产生的来源、水质特征及回用对选矿的影响,对自然净化法、酸碱中和法、混凝沉淀法、吸附法、化学氧化法、硫化沉淀法、生物法、膜分离法等应用于有色金属矿山选矿废水处理的研究成果进行了总结,分析指出了各自存在的优点和不足,其中对处理水体不产生二次污染的化学氧化法、吸附法、膜分离法将成为今后有色金属矿山选矿废水处理发展的重点方向;并进一步阐述了选矿废水源头分质回用、尾矿库溢流水回用及选矿废水末端处理回用在生产中的应用情况,指出了将多种选矿废水处理方法进行优化耦合应用,可进一步增强处理效果并达到回用的标准。
Nonferrous metals industry plays an important role in economic and social development,national defense science and technology industry,and the effective treatment of nonferrous metal mine dressing wastewater plays a crucial role in the stable and sustainable development of nonferrous metal industry.This paper introduces the sources,water quality characteristics and the main influence of the nonferrous metals processing of wastewater reuse,summarizes the advantages and disadvantages for teeating method,such as natural purification method,acid-base neutralization method,coagulation sedimentation method,adsorption method,chemical oxidation method,sulfide precipitation method,biological method and membrane separating method,etc.Among them,chemical oxidation method,adsorption method and membrane separating method,which can not produce secondary pollution,will become the key direction of the development of non-ferrous mineral processing wastewater treatment in the future.The practical application of the separation and reuse of the source,the reuse of the overflow water from the tailings pond and the reuse of the end treatment of the beneficiation wastewater in the production are further described.It is pointed out that the optimized coupling of various treatment technologies can further enhance the treatment effect and satisfies the reuse standard.
