摘　　要：采用介质阻挡放电等离子体/微曝气技术协同处理苯酚废水,考察放电电压、放电时间、溶液初始浓度及曝气量对苯酚处理效果的影响。研究结果表明：苯酚降解率随放电时间增加、苯酚初始浓度减小而提高;曝气量为150 m L/min时,苯酚降解率为51.8%。采用介质阻挡放电等离子体/微曝气协同工艺处理苯酚废水,与单独使用介质阻挡放电等离子体工艺相比,苯酚降解率提高了15%~20.4%。Phenol-bearing wastewater has been treated by dielectric barrier discharge plasma/micro-aeration process.The influences of discharge voltage,discharge time,solution initial concentration,aeration rate,on the phenol treatment effect are investigated. The research results show that the phenol degradation rate increases with the increase of discharge time,and increases with the decrease of phenol initial concentration. When the aeration rate i s150 m L/min,the phenol degradation rate is 58.1%. The degradation rate of phenol by using the combined dielectric barrier discharge plasma/micro-aeration process is 15% to 20.4% higher than the degradation rate of phenol by using single dielectric barrier discharge plasma process without micro-aeration.
