Because of their high persistence, polycyclic aromatic hydrocarbons (PAHs) are found in a wide range settings and pose health risk to both humans other organisms. Degradation PAHs is an essential part environmental management. By combining biological metabolism electrochemical processes, bioelectrochemical systems (BESs) can degrade provide important applications by converting the chemical energy pollutants into electrical for conversion recovery. This review provides comprehensive introduction PAH degradation BESs, including sources, effects performance enhancement methods, pathways, dominant microorganisms. focusing on relevant research recent years, main innovative focuses optimization configuration, electrode preparation, media additions improve removal PAHs. It demonstrates potential BESs field remediation, especially effectiveness treating difficult-to-degrade such as PAHs, concentrating application mechanism degradation. intended inexperienced reader with insight this area point out directions future research, design microbial community analysis.
