摘　　要： 通过对放电电压、甲基橙浓度、降解时间和溶液电导率等因素的考察,研究了高压放电降解甲基橙废水工艺.研究表明:在输入电压为11.2 kV,高压放电时间为10 min时,甲基橙的降解率能达到99%以上;甲基橙在高压放电下的降解反应属于假一级反应,随着初始浓度的增加,降解速率增加,降解后溶液呈酸性;甲基橙废水的电导率影响甲基橙的降解,随废水电导率增加,甲基橙降解率下降.甲基橙废水经高压放电后,废水的COD降解了87%,降解后水体澄清透明. The process of how high-voltage discharge degraded methyl orange wastewater was studied through researching the discharge voltage, concentration of methyl orange, degraded treating time and origin conductivity of wastewater. The result shows： the degradation rate of methyl orange can be more than 99% at an applied voltage of 11.2 kV and 10 rain;methyl orange degradation reaction in high-voltage discharge was first-order reaction, with the increase of initial concentration; the degradation rate increased and the wastewater was acidity after being degraded;the degradation of methyl orange was influenced bythe conductivity of it, and degradation rate decreased with the increasing of wastewater conductivity. After high voltage discharge treatment, the COD of wastewater degraded by 87%, and the water was clear and transparent .
