The removal of elemental mercury (Hg(0)) with the reactive species produced from dielectric barrier discharge (DBD) was studied. The effects of the operating parameters, such as the applied voltage, residence time, initial concentration and co-existence of other pollutants, were investigated. The removal of Hg(0) was significantly promoted by an increase in the applied voltage of the DBD reactor system. The presence of NO gas decreased the Hg(0) removal efficiency within the range of input powers tested compared to the case of Hg(0)-only due to the competition for ozone between Hg(0) and NO gas in the DBD reactor.
研究了利用介质阻挡放电(DBD)产生的活性物种去除元素汞(Hg(0))的情况。考察了操作参数如施加电压、停留时间、初始浓度以及其他污染物共存等的影响。DBD反应器系统施加电压的增加显著促进了Hg(0)的去除。与仅存在Hg(0)的情况相比,在测试的输入功率范围内,NO气体的存在降低了Hg(0)的去除效率,这是由于DBD反应器中Hg(0)和NO气体对臭氧存在竞争。
