摘要
染料废水产生量大、成分复杂、污染严重,使生态环境治理面临巨大压力,为使染料废水能够达标排放和综合利用,需要对其进行高效处理与利用。高级氧化技术利用强氧化性的羟基自由基(·OH)等活性物质,具有反应高效、降解彻底等特点。本文重点阐述了光催化、芬顿、臭氧氧化、湿式氧化、超声氧化、等离子体氧化、电化学氧化及超临界水氧化等高级氧化技术的基本原理;介绍了利用高级氧技术处理染料废水的相关研究;讨论了高级氧化技术的优势及不足;展望了高级氧化技术的发展方向和应用前景,为系统研究高级氧化技术处理染料废水提供参考。
Dye wastewater has put great pressure on the ecological environment due to the large amount,complicated composition and serious pollution thereof.To meet the discharge standards and achieve comprehensive utilization of dye wastewater,it is necessary to carry out efficient treatment and utilization.Advanced oxidation processes mainly use powerful oxidizing substances such as hydroxyl radicals(•OH).Advanced oxidation processes are characterized by high reaction efficiency and complete degradation,which have attracted widespread attention.The basic principles of advanced oxidation processes were described,such as photocatalysis,Fenton,ozone oxidation,wet oxidation,ultrasonic oxidation,plasma oxidation,electrochemical oxidation and supercritical water oxidation.The relevant research works on using advanced oxidation processes to treat dye wastewater were introduced.The advantages and disadvantages of advanced oxidation processes were also discussed.Their applications were prospected,which might provide a useful reference for the systematic study of advanced oxidation technologies.
