چکیده

In this study, the single chamber microbial fuel cel (MFC) with annular configuration and spiral anode geometry is suggested for future large-scaleapplications. Dairy wastewater containing complex organic matter was used as substrate. Factors affecting power generation and internal resistance of this MFC such as substrate injection, electrode surface area, and substrate concentration were investigated to elucidate the effects of the MFC configuration and operating conditions on its performance. The results show that with decreasing anode surface area output current is reduced. With decreasing anode surface area from 2×63 cm to 2×38 cm, output current is reduced about 34%. In measurement of open circuit voltage, replacement of old wastewater by fresh ones increases open circuit voltage significantly. Also, enhancement of wastewater concentration shows an increase in the MFC power density. The MFC which was fed with wastewater with lower COD had a shorter batch time than that of the higher wastewater COD.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
