Design of a novel DBD reactor for simultaneous decomposition of exhaust gas and wastewater
新型介质阻挡放电反应器同时处理废气和废液研究

In order to make full use of the ability of dielectric barrier discharge (DBD) to decompose pollutants, a reactor was designed to remove toluene and dye wastewater simultaneously according to the principles of treating wastewater and exhaust gas with DBD plasma. The effects of treating toluene and dye wastewater alone and together in the reactor are compared. The results show that the toluene can be effectively decomposed no matter whether it is treated alone or together with dye wastewater. The degradation efficiency of toluene was 88.6% when toluene and dye wastewater were treated together. Furthermore, dye wastewater can be decomposed at the same time while the decomposition rate of toluene remains essentially invariant. In this process, the decomposition of 50 mg·L-1 reactive brilliant blue can reach 95.4% after 60 min, representing a removal rate of 35.8 mg per hour. Accordingly, the energy efficiency of this reactor is increased through simultaneously decomposing toluene and dye wastewater and thus overall energy consumption is reduced.
