Tubular upflow microbial fuel cell (MFC) utilizing sea food processing wastewater was evaluated for wastewater treatment efficiency and power generation. At an organic loading rate (OLR) of 0.6 g d(-1), the MFC accomplished total and soluble chemical oxygen demand (COD) removal of 83 and 95%, respectively. A maximum power density of 105 mW m(-2) (2.21 W m(-3)) was achieved at an OLR of 2.57 g d(-1). The predominant bacterial communities of anode biofilm were identified as RB1A (LC035455), RB1B (LC035456), RB1C (LC035457) and RB1E (LC035458). All the four strains belonged to genera Stenotrophomonas. The results of the study reaffirms that the seafood processing wastewater can be treated in an upflow MFC for simultaneous power generation and wastewater treatment.
对利用海产品加工废水的管式上流微生物燃料电池（MFC）进行了废水处理效率和发电方面的评估。在有机负荷率（OLR）为0.6 g d⁻¹时，该MFC实现了总化学需氧量（COD）和可溶性COD去除率分别为83%和95%。在OLR为2.57 g d⁻¹时，最大功率密度达到105 mW m⁻²（2.21 W m⁻³）。阳极生物膜的主要细菌群落被鉴定为RB1A（LC035455）、RB1B（LC035456）、RB1C（LC035457）和RB1E（LC035458）。这四种菌株均属于嗜麦芽窄食单胞菌属。该研究结果再次证实，海产品加工废水可在上流MFC中进行处理，以实现同步发电和废水处理。
