| چکیده مقاله: |
| Environmental pollution as well as limitations of fossil fuel sources have attracted a lot of attentions towards renewable energy[1]. Microbial fuel cells are environmentally friendly technologies because they produce energy directly waste materials and operate under normal operating conditions, especially at ambient temperature[2]. Microbial fuel cells are similar to conventional fuel cells, except that instead of expensive metal catalysts, biocatalysts or microorganisms are used that are able to use organic fuel sources to convert convert the energy stored in their chemical bonds into bioelectricity simultaneously[1]. Dairy wastes are usually treated by physical-chemical and biological methods or a hybrid system of them, which are expensive due to the use of energy and oxygen [3] . Microbial fuel cells as a promising option are able to oxidize a wide range of substrates while simultaneously produces bioelectricity and wastewater treatment[4]. In this research, a single-chamber membrane-less microbial fuel cell with an air cathode has been used due to its simple structure, no need for aeration, and overcoming the limitations of a two-chamber configuration. Whey as the waste of chess production plant was collected from Kalleh dairy company, Amol, Iran and was used as the substrate. The activated carbon powder as the adsorbent prepared from corn waste a specific surface area of 1343m^2/gr and was used with a dosage of 4 g / L in the microbial fuel cell – adsorption hybrid system. The performance of microbial fuel cell with and without adsorbent was investigated in terms of bioelectricity production as well as treatment of dairy waste. The maximum power density in the microbial fuel cell with adsorbent was 2437 mW / m^3 compared to microbial fuel cell without adsorbent, 1478 mW /m^3 , which shows a 64% increase in electrical output when, Figure 1, while COD removal increase of 62% to 85%. |
