双向窄脉冲DBD放电印染废水脱色影响因素研究

Researches on Affecting Factors of Dying Waste Water Treatment by Bipolar Pulsed Discharge

研究了各因素对于双脉冲DBD放电反应器处理靛蓝废水的影响。结果发现:空气的曝入利于提高脱色效果;溶液的脱色效果随着外加电压的增加而提高,随电极间距、溶液的电导率的增加而降低。

Decoloration performance of the bipolar pulsed dielectric barrier discharge water treatment reactor is studied and factors that affect the decoloration rate are systemly discussed. Experimental results show that: Bubbling of water into the reactor facilitates the discharge and increases the removal rate of colorness. There is a economical value for the air flow rate, and under the condition of this reactor, it i 0.625 m^3/h; Decoloration rate of the reactor increases with the increase of the applied voltage, and decreases with the increase of the water conductivity and the distance between the two electrodes.
