摘要
首次采用新型两级介质阻挡放电(DBD)等离子体反应器对铬黑T、甲基橙等多种模拟印染废水进行降解处理。本反应器具有放电空间大、可连续处理废水等优点,对印染废水具有良好的降解效果。铬黑T、亚甲基蓝、甲基橙的降解率均可达到96%以上,亚甲基蓝的COD降解率达到77%。考察了在该反应器中甲基橙的初始p H、初始质量浓度以及放电电压对甲基橙降解率的影响。结果表明,新型两级DBD等离子体反应器处理甲基橙的适宜放电电压为110 V,较低的初始质量浓度和酸性利于甲基橙的降解。
A novel two-stage dielectric barrier discharge plasma reactor has been proposed and applied for degradation of chrome black T,methyl orange and other model wastewaters. The reactor can be applied for continuous wastewater treatment with large discharge space. The degradation rate of chrome black T,methylene blue and methyl orange can reach more than 96% and the COD degradation rate of methylene blue can achieve 77%. The effect of the initial p H,initial concentration and discharge voltage on the degradation of methyl orange is investigated. The results show that the optimum voltage of the two-stage dielectric barrier discharge plasma reactor is 110 V. Low initial concentration and acidic p H value are beneficial to the degradation of methyl orange.
