Weak electricity stimulates biological nitrate removal of wastewater: Hypothesis and first evidences
Original language description
Nitrate pollution in water is a worldwide health and environmental concern. Biological nitrate removal of wastewater is widely used countering eutrophication of water bodies: however it could be troublesome and expensive when influent carbon source is insufficient. Here we present a novel process, the microbial fuel cell (MFC)-resisLance-type electrical stimulation denitrification process (RtESD) using microbial weak electricity originated from the wastewater, to enhance nitrate removal. Results show that the optimal nitrate dependent denitrification rate (0,027 mg N/L. h) and nitrate removal efficiency (98,1%) can be achieved: partial autotrophic denitrification was enhanced in RtESD under stimulation of 0,2 V of microbial weak electricity (MWE). Aromatic proteins also increased in the presence of 0,2 V MWE stimulation according to three-dimensional excitation-emission matrix (3D-EEM) fluorescence spectroscopy profiles, indicating that electron transfer could be improved in the case of MWE stimulati
