过硫酸盐降解有机物活化技术研究进展

摘要：

过硫酸盐高级氧化作为新兴的废水处理技术,具有氧化能力强、pH适用范围广、本身化学性质稳定、降解效率高和无二次污染等特点,能够降解废水中多种难降解有机物.对国内外过硫酸盐降解有机物活化技术进行了比较,根据自由基产生的条件将活化方法分为赋能活化和化学活化两种类型.赋能活化方法包括热活化、光活化、超声活化、微波活化、电活化,化学活化方法包括过渡金属活化、碱活化、碳材料活化、有机质活化等,这些方法都可以有效激发SO4-·、HO·、O2-·、1O2等活性物质的产生,提高反应的效率和速率.不同方法联合使用,可以进一步提高降解效率.在以上研究基础上,总结了不同活化方法的基本原理、影响因素和优缺点.提出寻找更好的活化方式、更实用的活化剂以及研究更有效的联合高级氧化技术、以废治废等观点推动应用技术研究.

As an emerging wastewater treatment technology,persulfate advanced oxidation technology has the characteristics of strong oxidation capacity,wide application range of pH applications,stable chemical properties,high degradation efficiency and no secondary pollution,and it can degrade a variety of refractory organics in wastewater.In this paper,the activation techniques for persulfate degradation of organic pollutants at home and abroad are compared,and the activation methods are divided into two types:energizing activation and chemical activation.Energizing activation methods include thermal activation,photoactivation,ultrasonic activation,microwave activation,and electrical activation.Chemical activation methods include transition metal activation,alkali activation,carbon material activation,organic matter activation,etc.All these methods can effectively stimulate the generation of active species such as SO4-·,HO·,O2-·,1O2,and improve the efficiency and speed of the reaction.The combined use of different methods can further improve the degradation efficiency.On the basis of the above research,the basic principles,influencing factors,advantages and disadvantages of different activation methods are summarized.The authors put forward points of view to promote the research of applied technology,such as looking for better activation mode,looking for more practical activator,researching more effective combined advanced oxidation technology and treating waste with waste.
