选矿废水处理技术研究进展

The technology research progress on the mineral separation wastewater treatment

选矿废水是我国最主要的废水来源,约占工业废水的十分之一。选矿废水不仅量大,而且悬浮大量的无机离子、重金属离子以及浮选药剂等,任意排放不仅影响环境,而且会造成资源浪费。因此,如何有效去除这些有害物质以及进行选矿废水回用,具有重要意义。综述了国内选矿废水主要的处理技术与研究进展,结合各处理技术的优缺点对选矿废水处理未来发展趋势进行展望。

Being a major source of wastewate, mineral separation wastewater accounts for approximately one-tenth of the total industrail wastewater. Not only is the quantity of mineral separation wastewater large, but also the mineral separation wastewater contains a large amounts of inorganic ion, heavy metal ion and flotation reagents that causes serious environmental pollution when discharged arbitrarily. How to remove these harmful substances and reuse wastewater are of great significance. The research status of treatment technology in mineral separation wastewater is summarized in this paper. Based on the advan- tages and disadvantages of the processing technology of mineral processing, this paper also propects the developmental trend of treatment technology.
