摘　　要：采用10kV的高压脉冲放电与臭氧的联用装置,探讨了高压脉冲放电、臭氧和高压脉冲放电与臭氧协同处理200mg/L的活性艳红K-2BP模拟废水的脱色和COD的降解,以及加入自由基捕获剂对处理的影响。研究表明,三者氧化降解能力由大到小为:协同>臭氧>放电,加入自由基捕获剂对COD的去除率较不加自由基捕获剂时明显降低,但未对活性艳红K-2BP脱色产生明显的影响。Simulated wastewater containing reactive red dye K-2BP is treated using a bench-scale experimental device featuring integrated technology of high voltage pulsed discharge and ozone,and factors affecting the degradation rate of K-2BP are investigated.The synergetic action of high voltage pulsed discharge plus ozone in degradation of the red dye is clearly showed according to the experimental result in terms of COD removal and de-color.
