air-cathode microbial fuel cell for domestic wastewater treatment

主讲人 : taeho lee 教授

the study introduces a novel microbial electrochemical technology to enhance nitrogen removal instead of high power production from domestic wastewater. a flat-panel air-cathode microbial fuel cell (fa-mfc) successfully treated domestic wastewater to satisfy effluent quality standards of chemical oxygen demand (cod) and total nitrogen (tn) within a very short hydraulic retention time (hrt) of 2.5 h. the fa-mnc system allowed simultaneous removals of cod and tn from domestic wastewater, although it led to minimal power output. illumina miseq revealed that various bacterial communities involved in nitrification, denitrification, fermentation, sulfate reduction, and iron reduction were discovered in the fa-mnc system. four possible mechanisms for simultaneous nitrification and denitrification have been identified: (1) ammonia and nitrite oxidation using oxygen penetrated through the cathode, (2) heterotrophic denitrification at both the anode and cathode, (3) anaerobic ammonium oxidation in the anaerobic zone, and (4) autotrophic denitrification at the anode. the fa-mnc system can be an innovative and sustainable domestic wastewater treatment process.
