摘要：
Recently, refractory organic pollutants have been widely detected in natural water bodies, posing a serious threat to aquatic ecosystems and human health. The biofilm electrode technology is increasingly recognized as a promising approach in the field of recalcitrant pollutant treatment owing to its environmental friendliness, high removal efficiency, and wide applicability. In this study, a three-dimensional biofilm electrode reactors (3D-BERs) is constructed; the degradation mechanism of organic pollutants by 3D-BERs is elucidated; the synergistic degradation effect of electrochemical catalytic oxidation and electroactive microorganisms is analyzed; the enhanced degradation mechanism of pollutants is explicated from the perspective of electron migration; and the impact of construction methods and operational parameters of 3D-BERs on reactor efficiency is outlined. Furthermore, this study systematically reviews the application and advantages of 3D-BERs in treating refractory organic chemical wastewater, proposes the development prospects of 3D-BERs technology, and highlights the focus of future research efforts. Finally, this study aims to provide novel insights into the efficient treatment of recalcitrant organic chemical industrial wastewater to further promote the application and dissemination of biofilm electrode technology in the field of recalcitrant organic pollutant treatment. © 2024 Chemical Industry Press Co., Ltd..
