| 摘 要： | 采用高接触面积微孔曝气的方式,以吸附性多孔导电材料活性炭纤维（ACF）为电极，吸附电催化氧化两步联动降解气态氯苯，实现了在电解质水溶液中对高浓度非水溶性气态挥发性有机废气的有效处理。正交实验和单因素分析实验结合，确立最佳实验条件并着重考虑pH值、鼓气速率、电解电压、电解质浓度等因素对去除率的影响。在最佳实验条件下，气相中氯苯去除率达到74.3%（20℃）和72.9%（10℃）

| Abstract: | High concentration gaseous chlorobenzene was successfully removed by adsorption-eletrochemical oxidation in aqueous environment in which activated carbon fiber electrodes and micro-aeration were employed to realize the treatment.Optimal experimental parameters were determined by orthogonal and single factor effect test,and effects of pH,aeration rate,voltage and electrolyte concentration on the experimental results were considered.Under the optimal conditions,gaseous chlorobenzene removal was 74.3%(20℃)and 72.9%(10℃). |
