摘要：传统Fenton反应产生大量的铁泥,限制了该技术的推广应用。流化床Fenton是将传统Fenton和载体结晶相融合的一项高级氧化技术,在强化催化氧化废水处理效果的同时可以起到削减铁泥的作用。首先,文章从均相反应、非均相反应、载体结晶和技术机理4个方面,全面阐释了流化床Fenton的基本原理。继而,系统性地从载体特性、反应条件(Fenton试剂、pH、床层膨胀率和水基质)以及反应器结构等方面,全面分析了流化床Fenton工艺在废水处理中的关键影响因素。然后,回顾了近年来流化床Fenton工艺在难生物降解性工业废水等处理领域的工程化应用。最后,拓展性地从高效活性载体与耦合技术(光催化和膜生物处理)两方面详细地阐述了流化床Fenton技术优化,并对未来的研究方向和兴趣提出展望和思考。
The main disadvantage of traditional Fenton process is that it may produce large amounts of sludge and limits the application of water treatment.Fluidized-bed Fenton process is an advanced oxidation technology which combines Fenton process and carrier crystallization.Fluidized-bed Fenton can not only enhance the effect of catalytic oxidation,but also reduce the iron sludge.In this review,the basic principle of fluidized bed Fenton is comprehensively introduced from four aspects:homogeneous reaction,heterogeneous reaction,carrier crystallization and technical mechanism.Secondly,the key influencing factor of fluidized-bed Fenton process in wastewater treatment are systematically introduced from the aspects of carrier characteristics,reaction conditions(Fenton reagent,pH value,bed expansion rate and water matrices)and reactor structure.Then,the engineering application of fluidized-bed Fenton process in recalcitrant industrial wastewater treatment in recent years are critically reviewed.Finally,the optimization of fluidized-bed Fenton process is expandingly expatiated from the perspective of high efficiency active carrier and coupling technology(photocatalysis and membrane biological treatment),and propose feasible survey direction and interest on future research.
