Bioelectricity production from blue-green algae was examined in a single chamber tubular microbial fuel cell (MFC). The blue-green algae powered MFC produced a maximum power density of 11 4 mW/m(2) at a current density of 0.55 mA/m(2). Coupled with the bioenergy generation, high removal efficiencies of chemical oxygen demand (COD) and nitrogen were also achieved in MFCs. Over 78.9% of total chemical oxygen demand (TCOD), 80.0% of soluble chemical oxygen demand (SCOD), 91.0% of total nitrogen (total-N) and 96.8% ammonium-nitrogen (NH(3)-N) were removed under closed circuit conditions in 12 days, which were much more effective than those under open circuit and anaerobic reactor conditions. Most importantly, the MFC showed great ability to remove microcystins released from blue-green algae. Over 90.7% of MC-RR and 91.1% of MC-LR were removed under closed circuit conditions (500Ω). This study showed that the MFC could provide a potential means for electricity production from blue-green algae coupling algae toxins removal.
在单室管状微生物燃料电池 (MFC) 中研究了从蓝绿藻中产生的生物电能。蓝绿藻为动力的 MFC 在电流密度为 0.55 mA/m²时产生了 114 mW/m²的最大功率密度。与生物能源的产生相结合，MFC 还实现了高去除化学需氧量 (COD) 和氮的效率。在 12 天内，闭路条件下总化学需氧量 (TCOD) 的去除率超过 78.9%，可溶化学需氧量 (SCOD) 的去除率超过 80.0%，总氮 (总-N) 的去除率超过 91.0%，氨氮 (NH₃-N) 的去除率超过 96.8%，这比开路和厌氧反应器条件下的去除率高得多。最重要的是，MFC 表现出了从蓝绿藻中去除微囊藻毒素的巨大能力。在闭路条件下（500Ω），超过 90.7%的 MC-RR 和 91.1%的 MC-LR 被去除。本研究表明，MFC 可以为从蓝绿藻中产生电能并去除藻类毒素提供一种潜在的手段。
