| 摘 要： | 依据介质阻挡放电(DBD)和溶液吸收处理气态污染物的原理,设计出一种DBD和水吸收联合降解挥发性有机化合物(VOCs)的实验装置.研究其对甲苯的降解效果.考察了放电电压、甲苯初始浓度、模拟废气流量对甲苯降解效果的影响.分析了DBD和水吸收的相互作用.结果表明.DBD和水吸收联合可以提高甲苯的降解率.在放电电压为15.9 kV时甲苯的降解率为81.5%.比单独放电时提高了13.3百分点;甲苯的降解率随着放电电压增大而升高,随着气体流量和甲苯初始浓度增大而降低.该技术可以作为放电等离子体前处理工艺,为高效处理上业废气提供参考. |

| Abstract: | VOCs decomposition experiments were conducted in a reactor, which was built to accommodate both decomposition with dielectric barrier discharge (DBD) and water absorption, to determine effects of discharge voltage, influent flow rate, toluene concentration, and water absorption on the toluene decomposition rate. With water adsorption, the combined DBD and adsorption treatment was more effective; relative to the DBD at 15.9 kV alone, the toluene decomposition rate increased from 68.2% to 81.5%. The toluene d... |
