摘要
随着工业发展,印染废水处理已成为环境保护的重要课题。活性艳蓝KN-R作为一种典型的印染废水染料,其降解效率直接影响废水处理的质量和环境安全。本研究针对活性艳蓝KN-R印染废水处理问题,设计了降膜式介质阻挡放电(DBD)等离子体反应器。实验结果显示,该装置在25 min内可有效去除84.30%的活性艳蓝KN-R。进一步将DBD等离子体与芬顿反应相结合,显著提升了染料的降解效率和矿化率。研究还分析了降解过程中的关键活性物质和降解途径,阐明了DBD等离子体与芬顿反应的协同作用机制,并且此体系在处理过程中二次污染少,对环境友好,这些发现为低温等离子体技术在工业废水处理中的应用提供了理论支持和实践指导。
With the development of industry,the treatment of printing and dyeing wastewater has become an important issue in environmental protection.As a typical dye in printing and dyeing wastewater,the degradation efficiency of reactive brilliant blue KN-R(RBB KN-R)directly affects the quality of wastewater treatment and environmental safety.Aiming at the problem of treating RBB KN-R printing and dyeing wastewater,this study designed a falling film dielectric barrier discharge(DBD)plasma reactor.The experimental results show that this device can effectively remove 84.30%of RBB KN-R within 25 min.Further combination of DBD plasma with the Fenton reaction significantly improves the degradation efficiency and mineralization rate of the dye.The study also analyzes the key reactive substances and degradation pathways during the degradation process,clarifies the synergistic mechanism between DBD plasma and the Fenton reaction.Moreover,this system causes less secondary pollution during the treatment process and is environmentally friendly.These findings provide theoretical support and practical guidance for the application of low-temperature plasma technology in the treatment of industrial wastewater.
