摘　　要：针对浮选废水中捕收剂难降解矿化问题,综述了高级氧化技术(AOPs)在浮选废水深度处理中的研究进展.国家层面工业废水循环利用和绿色矿山建设政策为浮选废水深度处理与回用指明了方向,浮选废水中捕收剂在选矿废水回用中降低浮选指标,且其排放会污染矿区环境,是棘手的矿冶环境污染控制难题.AOPs主要通过电、光辐照、催化剂等产生具有强氧化能力的活性氧化物种对捕收剂快速降解矿化,在浮选废水深度处理领域备受关注.通过浮选废水来源与特性分析,针对黄药类、黑药类、肟酸类捕收剂,综述了芬顿与类芬顿氧化、臭氧氧化、电化学氧化、光化学氧化、过硫酸盐氧化等AOPs处理浮选废水中捕收剂的过程机理与研究进展.进一步综述了影响AOPs处理浮选废水的主要因素与过程机制,包括氧化剂剂量,废水pH,共存无机阴离子、金属离子、溶解性有机质等,优化调控这些因素可提高AOPs降解矿化捕收剂效率.综合AOPs降解矿化浮选废水中捕收剂研究进展,指出其中存在的问题和发展方向,为AOPs在浮选废水深度处理中研究与应用提供重要参考.Addressing the challenge of refractory mineralization in flotation wastewater,this paper reviews advanced oxidation processes(AOPs)for advanced treatment.National policies on industrial wastewater recycling and green mine construction have highlighted the need for advanced treatment and reuse of flotation wastewater.The residual collectors can diminish the efficacy of flotation in wastewater reuse,leading to environmental pollution.AOPs,which generate reactive oxygen species with potent oxidation capabilities,are increasingly recognized for their ability to rapidly degrade and mineralize collectors using electricity,light irradiation,and catalysts.This review examines the sources and characteristics of flotation wastewater,delves into the process mechanisms and research advancements of AOPs for collector degradation,including Fenton-like and ozone oxidation,electrochemical,photochemical,and persulfate oxidation.It also discusses factors influencing AOPs'effectiveness,such as oxidant dosage,wastewater pH,coexisting inorganic anions,metal ions,and dissolved organic matter.Optimizing these factors can enhance the efficiency of collector degradation and mineralization by AOPs.The research progresses of collectors degradation and mineralization in flotation wastewater by AOPs were summarized,and the existing problems and development directions were pointed out,which provides an important reference for the research and application of AOPs in the advanced treatment of flotation wastewater.
