The looking for sustainable sewage sludge management technology in the wastewater treatment plants, has brought to light the biocathode microbial fuel cells (bMFCs) which allow simultaneous biological stabilization and direct energy generation, avoiding the production of biogas. In the present study, the performance of bMFCs for the treatment of secondary sludge as anodic substrate was evaluated by analyzing the removal of organic matter, destruction of volatile solids and the generation of electrical energy under different operating conditions and applying two types of cathode chambers. The results indicated that VSS and tCOD removals up to 92% and 87% respectively can be achieved in the anodic chamber generating simultaneously energy. Current and power densities of 1.80 ± 0.09 A∙m−3 and 0.43 ± 0.02 W∙m−3 respectively were reached, showing that bMFCs are a reliable alternative to generate electricity during the sewage sludge stabilization process. It was revealed that the pH value and the type of cathodic zone are statistically significant factors that influenced the performance of the bMFCs. The obtained results demonstrated that the electrochemical performance of the bMFCs was better at pH value of 6 in the anodic chamber and when aerobic cathode zone was used.

Abstract Searching for efficient and inexpensive catalysts to replace precious metal-based catalyst in air-cathode microbial fuel cells is crucial for the practical application and commercialization in wastewater treatment and energy generation. Here, through a simple pyrolysis process, sewage sludge could be converted into carbon material with hierarchically porous structure, which demonstrates oxygen reduction reaction (ORR) catalytic performance. Subsequently, co-doping Mn and N species on the carbonized sewage sludge matrix could further improve the ORR catalytic performance, which even demonstrates comparable performance to the commercial expensive Pt/C catalyst in air-cathode microbial fuels cells (MFC). The highest maximum power density of MFC with Mn-N/SC air-cathode is as high as 1,120 mW m−2, which is similar to the power density of the air-cathode MFC equipped commercialized Pt/C catalyst (1,240 mW m−2). Considering the simple operation, significant cost-saving and easy scale-up of the proposed ‘trash-to-treasure’ method, it is promising to convert harmful sewage sludge into efficient non-platinum cathode catalysts in microbial fuel cells.
