摘要
用基于产生强氧化剂—羟基自由基的高级氧化技术处理难降解废水已成为近年来的研究热点。而高级氧化技术中的电Fenton法又以其独特的优点倍受人们的青睐。根据电生成Fenton试剂方法的不同,概括了电Fenton法的主要类型及其机理,介绍了各类型的优缺点及其在国内外的研究状况。同时,还介绍了电Fenton法与其它废水处理技术的联合工艺,对难降解废水具有很好的处理效果。最后,指出电Fenton法今后研究发展方向。
Advanced oxidation technology, Based on strong oxidants-hydroxyl radical degrades refractory wastewater, has become a hotspot in recent years. One of the advanced oxidation technologies, Electro-Fenton, has attracted more and more interest because of it own unique advantages. According to different methods of electrogenerating Fenton＇s reagent, the main types of Electro-Fenton method and their mechanism were summarized, and the advantage and disadvantage of the various types were presented, and also the status of its study around the world was pointed out. At the same time, the paper also introduced the joint process between Electro-Fenton method and conventional wastewater treatment technologies, and it has a good treatment effect to refractory wastewater. Finally, the future development of the Electro-Fenton method has been presented.
