摘要: 将有机废气通过高效微孔曝气转移到液相,采用活性碳纤维作为电极,研究不同鼓气速率和不同电压对处理效果的影响.结果表明,本方法适用于低浓度高气量有机废气的处理.在实验范围内,当曝气速率为20L·h-1,外加电压为5V的条件下,处理速率最稳定.Abstract: In this study,simulated organic waste gas was transferred from gaseous medium to aqueous medium through high-efficient micropore aeration.Porous conductive medium——activated carbon fiber(ACF)was selected as electrode.Effects of different aeration rate and different additional voltage on removal efficiency were investigated.Results show that the method is suitable for the treatment of gas with low concentration and large amount.In the experiment range,the removal rate is most constant under the aeration rate of 20L·h-1 and additional voltage of 5V.
