摘要
矿山废水主要产生于采矿作业以及选矿作业过程中,废水中的污染物包括重金属离子、油类、酸、氰化物和氟化物等。本文介绍了矿山废水的来源、特点以及危害,阐述了含难降解有机物和重金属离子等矿山废水最常用的处理方法,如离子交换法、吸附法、膜技术、酸碱中和法、混凝沉降法、化学沉淀法、化学氧化法和电化学法等典型废水处理技术,并概述各处理方法的基本原理和优缺点,展望未来矿山废水处理技术的研究发展方向。
Mine wastewater is mainly produced in the process of mining operation and mineral processing operation.The pollutants in wastewater include heavy metal ion,oil,acid,cyanide pollution,fluoride and so on.Based on the introduction to the source,characteristics and harm of mine wastewater,the most commonly used treatment methods of mine wastewater containing plant organic matter and heavy metal ions,such as ion exchange,adsorption,membrane technology,acid and alkali neutralization,coagulation sedimentation method,chemical precipitation,chemical oxidation,electrochemical method and many other typical wastewater treatment technology are introduced.The basic principle,advantages and disadvantages of each processing method are summarized.The research and development direction of mine wastewater treatment technology in the future is prospected.
