摘　　要：选矿废水处理对减少环境污染、节约水资源、促进矿业可持续发展具有重要意义。对选矿废水处理技术现状进行了综述,在分析选矿废水来源、特点及其危害的基础上,总结了选矿废水的物理、化学和生物等处理技术的研究进展。结果表明,混凝-絮凝和吸附等物理方法处理速度较慢,且对有机药剂等复杂污染物的去除效果有限;芬顿法和臭氧法等高级氧化技术因其操作简单、效率高,有望成为未来选矿废水处理的重要发展方向;微生物法具有无二次污染的显著优势,但亟需解决处理时间长及微生物对选矿废水环境难适应等问题。未来可将不同的工艺进行组合,形成针对不同回用需求的选矿废水处理技术体系。Flotation wastewater treatment is of great significance to reduce environmental pollution, save water resources and promote the sustainable development of the mining industry. The present situation of treatment technology of flotation wastewater was reviewed, based on the analysis of the source, characteristics and harm of flotation wastewater, the research progress of physical, chemical and biological treatment technology of flotation wastewater was summarized. The results show that the physical methods such as coagulation-flocculation and adsorption have slow processing speed, and the removal effect of complex pollutants such as organic agents is limited. Advanced oxidation technologies such as Fenton method and ozone method are expected to become an important development direction of flotation wastewater treatment in the future because of their simple operation and high efficiency. The microbial method has a significant advantage of no secondary pollution, but it is urgent to solve the problems of long treatment time and difficult adaptation of microorganisms to the environment of flotation wastewater. In the future, different processes can be combined to form a treatment technology system of flotation wastewater for different reuse needs.
