摘要(Abstract)：

为有效解决印染废水造成的环境难题,采用新型降膜介质阻挡反应器研究了在不同的输入功率、溶液初始浓度、初始电导率、溶液处理量和初始pH等条件下对甲基橙溶液的连续降解,并对降解效果进行了比对。结果表明:最佳的工艺参数分别是输入功率为72.5 W,初始浓度为150 mg?L-1,处理量为150 mL,放电气体流量为300 mL?min-1;较低的初始电导率和初始pH值对甲基橙溶液的降解有促进作用;150 mL浓度为150 mg?L-1的甲基橙溶液在介质阻挡放电等离子体作用下处理30 min,甲基橙降解率达到93.7%。利用液相色谱-质谱联用仪及紫外分光光度计对甲基橙降解过程的中间体及产物进行了分析,提出了甲基橙在降膜介质阻挡放电作用下的降解机理。
