| 英文摘要 | To harvest electricity and mitigate methane emissions from wetlands, a novel microbial fuel cell coupled constructed wetland (MFC-CW) was assembled with an anode placing in the rhizosphere and a cathode on the water surface. Plant-mediated methane accounted for 71-82% of the total methane fluxes. The bioanode served as an inexhaustible source of electron acceptors and resulted in reduced substantial methane emissions owing to electricigens outcompeting methanogens for carbon and electrons when substrate was deficient. However, when supplying sufficient organic carbon, both electricity and methane increased, indicating that electrogenesis and methanogenesis could co-exist in harmony. Direct methane emission (diffusion/ebullition) and plant-mediated methane emission were affected by operating conditions. Methanogenesis was significantly suppressed (similar to 98%) at HRT of 96 h and with external resistance of 200 X, accompanied with improved coulombic efficiency of 14.9% and current density of 187 mA/m(2). Contrarily, change of electrode polarity in the rhizosphere led to more methane efflux. (C) 2017 Elsevier Ltd. All rights reserved. |
