Mismanaged antibiotics ending up in aquatic environment due to inadequate conventional treatment urges the need to develop powerful advanced oxidation techniques. In this study, hybrid bifunctional rotating drum reactor (BRDR) has been developed and its potency in enhancing the degradation of ciprofloxacin has been demonstrated. BRDR is a hybrid reactor that integrates – photoelectrocatalysis (PEC) and photo-electro-Fenton (PEF) processes with UVA irradiation. It consists of MoS₂-TiO₂-coated carbon cloth as anode and Ferrocene-functionalized graphene-coated graphite felt as cathode. BRDR system significantly improved the removal efficiency (99.9 %) as compared to individual efficiencies of PEC (71 %) and PEF (78.8 %) processes. An increase in electrode rotation speed significantly enhanced the removal without external aeration (0.059 min⁻¹ for 60 rpm). Maximum removal rate was achieved at pH 3 (0.061 min⁻¹) followed by 7 (0.040 min⁻¹) and 9 (0.020 min⁻¹). The increase in applied potential from open circuit voltage to 1.5 V improved the removal rate from 0.005 min⁻¹ to 0.040 min⁻¹. The mechanism of reactive oxygen species production in BRDR system is elaborated. BRDR is demonstrated to be cleaner treatment system which excludes the external chemical addition, aeration, and sludge formation.

由于常规处理不足，管理不善的抗生素最终进入水生环境，这促使需要开发强大的高级氧化技术。在本研究中，开发了混合双功能转鼓反应器 (BRDR)，并证明了其增强环丙沙星降解的效力。BRDR 是一种混合反应器，将光电催化 (PEC) 和光电芬顿 (PEF) 工艺与 UVA 辐照相结合。它由 MoS ₂ -TiO _2组成涂层碳布作为阳极，二茂铁功能化石墨烯涂层石墨毡作为阴极。与 PEC (71 %) 和 PEF (78.8 %) 工艺的单独效率相比，BRDR 系统显着提高了去除效率 (99.9 %)。电极旋转速度的增加显着增强了无需外部曝气（0.059 min ^-1 for 60 rpm）的去除。^{在 pH 3 (0.061 min -1} )下达到最大去除率，然后是 7 (0.040 min ^-1 ) 和 9 (0.020 min ^-1 )。外加电位从开路电压增加到 1.5 V，去除率从 0.005 min ^-1提高到 0.040 min ^-1. 阐述了BRDR系统产生活性氧的机理。BRDR 被证明是一种更清洁的处理系统，它排除了外部化学添加、曝气和污泥形成。
