Abstract

Abstract:

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 in-crease of discharge time,and increases with the decrease of phenol initial concentration. When the aeration rate is 150 mL/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.

Key words: dielectric barrier discharge plasma, micro-aeration, phenol wastewater

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 mL/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%。
