负载型TiO2在双脉冲放电水处理中的应用
Application of Loaded TiO2 to Water Treatment by Bipolar Pulsed Discharge
摘要
Abstract
Aqueous phase electrical discharge has been used to remove organics in water. Photo radiation is one of the main physical effects accompanying the discharge that can be used by photocatalyst. Therefore, the effect of the photocatalyst to the degradation of the organic pollutant is investigated using a packed bed reactor by bipolar pulsed discharge in the air-water-solid mixture. The loaded nanoparticle TiO2 photocataiyst is obtained using the sol-gel method and dye solution is chosen as the target to test the catalytic effect of the nanoparticle TiO2 photocatalyst. Experiment results prove that the degradation efficiency of the indigo solution increases as the photocatalyst presenting in the plasma reactor. And the catalytic enhancement effect increases with the increase of the thickness of TiO2 coating. In addition, the synergistic effect decreased a little when applied voltage increased while increased with the increase of the gas flow rate. The indigo solution is totally decolorized Within 3 min by bipolar pulsed discharge under the condition of a 30 kV peak voltage and 1.0 ma/h air flow.关键词
