摘要
滑动弧放电是一种可在常压下产生非平衡等离子体的新型低温等离子体技术。通常在2或3个及更多的电极间形成电弧,在电弧区形成热或冷的等离子体。为比较完整地了解滑动弧放电在水处理方面的进展,综述了滑动弧放电在水处理方面的文献。阐述了滑动弧放电等离子产生的基本原理及处理废水的机理;介绍了滑动弧放电等离子体处理废水的两种装置及其优缺点;分析了水处理过程中产生的活性离子种类、检测方法及研究现状;介绍了目前滑动弧放电等离子处理废水的现状;最后展望了滑动弧等离子处理废水的前景。
In order to acquire a more full acquaintance about application of gliding arc discharge plasma to wastewater treatment, the literatures about application of gliding arc discharge to treating water were summarized systemically. The paper reviewed its concept and the basic principle of coming into being gliding arc discharge and the mechanism of disposing wastewater. Then the paper introduced the development and virtues and disadvantages of two kinds of experimental set-ups, namely, liquid and gas-liquid gliding arc discharge, and analyzed current research situation and measurement methods of active species such as HO ·, NO · , H2O2 and so on , these active species were engendered by gliding arc discharge plasma in wastewater treatment, they played an important role in degrading wastewater, especially HO·. The research progress of gliding arc discharge plasma dealing with wastewater abroad and in domestic is reviewed, including different variety of wastewater, influencing factors, abatement efficiency, intermediate products, degradation mechanism etc. Finally, the paper presented existing problems, such as how to reduce energy consumption, how to perfect electrode shape, how to identify the intermediates and final products, how to associate with other degrading techniques etc, and developing tendency of gliding arc discharge plasma technology in the future.
