| 英文摘要 | The electrode plays a significant role in an integrated anaerobic digestion reactor with microbial electrolysis that can increase energy production. Optimizing electrode positions by means of hydrodynamic analysis was proven feasible. In this work, different spatial distributions of bioelectrodes in upflow integrated anaerobic digestion reactors were researched to obtain a highly effective configuration. The hydrodynamic characters of each reactor were evaluated by a residence time distribution (RTD) test and computational fluid dynamics (CFD) simulation. The optimal structural design in this work was in that electrodes were placed at the bottom of the reactor with the cathode placed above the anode, It had an obvious hydrodynamics advantage and generated maximum methane production of 304.5 mL CH4/L reactor/day and a maximum chemical oxygen demand (COD) removal of 92.1% at a hydraulic retention time (HRT) of 36 h. The better flow pattern was in favor of mass transfer and further improved the reactor performance. The hydrodynamics character also affected the distribution of functional communities attached to the electrode surface. Results implied that Enterobacteriaceae and Desulfovibrio were sensitive to hydrodynamic shear. Methanogens on electrodes had the highest diversity under higher hydrodynamic shear when electrodes were placed on the bottom of the reactors with the best flow regime among that of other positions. |
