- 摘要:
- 为了提高电芬顿法对印染废水的处理效能,制备了石墨烯气体扩散电极(GDE),并设计了非浸没式防水曝气器,考察了防水曝气模式下石墨烯GDE电芬顿系统对染料废水的处理效能及反应机制。结果表明,石墨烯GDE具有良好的电芬顿催化活性,其性能显著优于常规不锈钢和碳毡电极;防水曝气模式能够克服水中O2浓度限制,提升H2O2产量和染料脱色率,并在电极表面形成剪切扫洗效应,强化电极稳定性和抗污染性;在防水曝气模式下石墨烯GDE具有良好的稳定性、重复利用性以及对不同类型染料的普适性;当反应体系中有Fe2+时,对有机染料降解起主要贡献的自由基是·OH和1O2,而无Fe2+时,起主要贡献的自由基是1O2和·O2-。
- Abstract:
- To improve the treatment efficiency of printing and dyeing wastewater by the electro-Fenton method, a graphene gas diffusion electrode (GDE) was prepared and a non-immersive waterproof aerator was designed. The treatment efficiency and reaction mechanism of the graphene GDE electro-Fenton system for dye wastewater under waterproof aeration mode were investigated. The results showed that the graphene GDE exhibited good electro-Fenton catalytic activity, and its performance was significantly superior to that of conventional stainless steel and carbon felt electrodes. The waterproof aeration mode could overcome the limitation of dissolved oxygen concentration in water, increase H2O2 production and dye decolorization rate, and generate a shear-scouring effect on the electrode surface, thereby enhancing electrode stability and anti-fouling property. Under the waterproof aeration mode, the graphene GDE demonstrated good stability, reusability, and universal applicability to different types of dyes. When Fe2+ was present in the system, ·OH and 1O2 were the primary radical contributing to the degradation of organic dyes; in the absence of Fe2+, the main contributing radicals were 1O2 and ·O2-.
