摘 要: 利用接触辉光放电电解(CGDE)技术降解亚甲基蓝和甲基紫染料废水,探讨了工作电压、反应液pH值、辉光放电时间和电解质Na2SO4浓度对降解效果的影响。试验表明,利用该方法可以使水中阳离子染料完全降解。亚甲基蓝和甲基紫的优化降解条件均为:工作电压700V、pH值9、辉光放电时间45min、Na2SO4用量2g/L。 Contact glow-discharge electrolysis (CGDE) is a novel technology for wastewater treatment. Degradation of methylene blue and methylene violet individually was carried out by CGDE method. Factors of operating voltage, pH value of the solution, and the concentration of Na2SO4 on degradation are discussed. Results show that cationic dyestuffs can be degraded thoroughly under the following conditions, which are, operating voltage 700 V, Na2SO4 2g/L and pH value 9.0, electric glow discharging for 45 minutes.
