摘　　要：以工业印染废水为降解目标,采用介质阻挡放电等离子体技术,研究了不同电极结构、放电电压、放电功率以及放电气氛对降解印染废水的影响。结果表明,不同电极结构会影响印染废水的降解效果,铜网越密集,放电效果越好,降解效果越好;且铜片电极降解效果最佳。放电电压越高、放电功率越大,降解效果越好,综合考虑等离子体功率转化效率,当放电100V时,等离子体反应器效率最高,降解效果也较好。当放电间距为3 mm时,降解效果为佳。空气放电好于氮气和氩气气氛放电,因为空气放电不仅可以产生大量活性粒子,还可以产生臭氧,形成协同效应,从而提高降解效果。Taking industrial printing and dyeing wastewater as the degradation target,the effects of different electrode structures,discharge voltage,discharge power and discharge atmosphere on the degradation of printing and dyeing wastewater were studied by dielectric barrier discharge plasma technology.The results show that different electrode structures will affect the degradation effect of printing and dyeing wastewater.The denser the copper mesh,the better the discharge effect and the better the degradation effect.The copper sheet electrode has the best degradation effect.The higher the discharge voltage and the greater the discharge power,the better the degradation effect.Considering the plasma power conversion efficiency,when the discharge is 100 V,the plasma reactor efficiency is the highest and the degradation effect is also better.When the discharge spacing is 3 mm,the degradation effect is better.Air discharge is better than nitrogen and argon atmosphere discharge,because air discharge can not only produce a large number of active particles,but also produce ozone,forming a synergistic effect,thereby improving the degradation effect.
