A STUDY ON DEVELOPMENT OF A WASTEWATER TREATMENT SYSTEM FOR ELECTRICITY RECOVERY USING MICROBIAL FUELS CELLS

研究了微生物燃料电池（MFCs）将有机化合物中的化学能直接转化为电能，用于污水处理和生物发电的同时进行。采用双室MFCs和空气阴极单室MFCs对人工废水发电进行了研究。厌氧污泥和活性污泥作为生物催化剂。空气阴极单室mfc具有较高的功率密度。结果表明，活性污泥中的电化学活性细菌与厌氧污泥中的电化学活性细菌不同。为了实现MFC系统，还需要进一步改进反应器和MFC细菌的信息。

Microbial fuel cells (MFCs) were studied for simultaneous wastewater treatment and biological electricity generation by direct conversion of chemical energy in organic compounds into electricity. Electricity generation from artificial wastewater was examined using two-chamber MFCs and air-cathode single-chamber MFCs. Anaerobic sludge and activated sludge were used as biocatalysts. The air-cathode single-chamber MFCs showed higher power densities. It was suggested that electrochemically active bacteria in activated sludge differed from those in anaerobic sludge. For realization of the MFC systems, improvement of the reactors and information on the MFC bacteria will be further needed.
