Abstract: The transformation and degradation of hydrophobic emerging contaminants (HECs) now became research hot spots due to the characteristics of widespread distribution, persistence, and refractory of HECs. Bioelectrochemical system (BES) is a flourishing technology for the remediation of various contaminants and has been proven to efficiently transform and degradation of HECs. In this work, the effect of BES operational factors on HECs' removal performance was analyzed, the effectiveness of BES technology in treating various HECs was evaluated, and the feasibility and superiority of integrating BES into traditional treating technologies, such as anaerobic digestion, wetlands, photocatalysis, etc., were discussed as well. Besides, the prospective development of functional electrode materials, the mechanism of HECs' transformation and degradation, and the engineering applications of BES technology were proposed. This review is excepted to provide theoretical and technical supports for future research and promote the BES technology closer to the practical application.
