摘　　要：研究多针-板电极形式的高压脉冲放电等离子体体系对酸性橙Ⅱ染料废水的脱色效果,并研究脱色机 理．结果表明,实验中所采用的多针-板电极形式的高压脉冲放电等离子体体系对酸性橙Ⅱ染料废水的脱色效果 明显．在相同的脉冲电压下,系统的脉冲频率、电极间距以及溶液初始pH值和初始浓度等因素对溶液的脱色效 果影响显著．在脉冲电压为30 kV,脉冲频率为75 Hz,电极间距为2．5 cm的实验条件下,反应体系放电60 min 对酸性橙Ⅱ的脱色率可达92．7％．此项研究结论为进一步研究多针-板电极形式的高压脉冲放电等离子体体系的 放电作用提供了依据．Decoloration efficiency of azo dye (acid orange 7, AO7) wastewater using a multi-needle-to-plate high voltage pulsed discharge plasma system was investigated. The obtained results showed that the multi-needle-to-plate high voltage pulsed discharge plasma system could decolor AO7 efficiently. In the case of the uniform pulsed voltage, effect of varied parameters, including pulsed frequency, electrode distance of the pulsed discharge system, initial pH and concentration of the dye aqueous solution, on the decoloration rate was reviewed. Under the condition of 30 kV pulsed voltage, 75 Hz pulsed frequency, and 2.5 cm electrode distance; decoloration efficiency of AO7 could reach 92.7% after 60 min discharge treatment. These conclusions provided an experimental foundation for the further study on the discharge effect of a multi-needle-to-plate pulsed discharge plasma system.
