Abstract

Hazardous organic contaminants tend to accumulate in the industrial effluents due to their recalcitrant properties. Approaches used for the hazardous contaminants removal always encounter conflicts between treatment efficiency and economic efficiency. Bioelectrochemical system (BES) is an attractive new type of wastewater treatment technology, which is versatile with the advantages of low energy demand, less sludge production, and synchronous resource recovery. Electrons microbially generated from the anode of BES enable bioremediation processes for removing persistent pollutants in wastewater. Highly oxidized hazardous organic contaminants could be efficiently reduced at abiotic/biocathode driven by bioanodes. This review summarized a series of typical hazardous organic pollutants transformation or degradation in BESs from the views of process operation, functional bacteria, and mechanisms. In addition, as an extent of anaerobic technology, BES coupling with traditional anaerobic process is considered as a promising way to achieve energy-efficient wastewater treatment and deliver scaled-up applications of BESs. Moreover, the main hurdles and future perspectives as well as potential future research are discussed.
