ABSTRACT：
Sustainable wastewater treatment demands maximized resource recovery and minimized resource consumption. Recovery of valuable resources such as energy, nutrient, water, and other value-added products, will help offset resource consumption by wastewater treatment. Bioelectrochemical systems (BES), as an emerging treatment concept, have attracted a great deal of attention in the past decades. BES rely on the interaction between microorganisms and solid electron acceptor/donors to achieve bioelectricity generation (in microbial fuel cells – MFCs), hydrogen production (in microbial electrolysis cells–MECs), desalination (in microbial desalination cells–MDCs), and organic synthesis (in microbial electrosynthesis cells). Nutrients such as ammonia and phosphorous can also be recovered through electricity-driven processes. BES have been greatly advanced in the aspects of microbiology, chemistry, materials, electrochemistry, and reactor design/operation. However, there still lack successful pilot-scale demonstrations of BES. In this presentation, we will provide an overview of historical evolvement of BES, current status of representative BES technologies, and perspectives towards future development. A key missing parameter in BES research, energy performance including both energy recovery and consumption, will be analysed in depth for various BES technologies. The synergy between BES and other existing/new technologies, such as membrane bioreactors, algal bioreactors, and forward osmosis, will be discussed with a focus on resource recovery. The key challenges, for example system scaling up, operation optimization, and material selection, will also be discussed.
