摘要
试验研究了雾化介质阻挡放电过程中产生的低温等离子体对靛蓝二磺酸钠(C16H8N2Na2O8S2)染料废水的脱色效果。通过对染料浓度变化的测定表明,高压电极加入高压后,水电极在电场力的作用下雾化,大量的低温等离子体活性物质生成;在相同的处理时间内,染料溶液的浓度随着电压的升高和空气间隙的减小而降低;对染料脱色起重要作用的物质是雾化介质阻挡放电过程中产生的低温等离子体活性物质。
The decoloration of indigo carmine aqueous solution with the non-thermal plasma from the spraying dielectric barrier discharge （DBD） system was investigated. The results showed that： （1） After the high-voltage was applied to the high-voltage electrodes, the water electrode was started to atomize under the process of the electric field. This phenomenon created a mass of non-thermal plasma active species. （2） The concentration of the dye decreased with the increase in applied high voltage and the decrease in air gaps under the same treatment time. （3） The key factor to decolorization is various non-thermal plasma active species which came from the spraying dielectric barrier discharge.
