| Abstract in Brazilian Portuguese: | A operação da célula de combustível microbiana (MFC) em condições semelhantes aos métodos convencionais apoiará o uso deste tecnologia no tratamento de águas residuais em grande escala. A operação do MFC de cátodo de ar ampliado (2 L) alimentado com águas residuais sintéticas (semelhantes às domésticas) em fluxo contínuo foram avaliadas usando três diferentes sistemas hidráulicos tempos de retenção (TRH), 12, 8 e 4 h. Descobrimos que a produção de electricidade e o tratamento de águas residuais poderiam ser melhorado sob uma TRH de 12 horas. Além disso, o TRH mais longo levou a uma maior eficiência coulombiana (5,44%) do que MFC operando em 8h e 4h, 2,23 e 1,12%, respectivamente. No entanto, devido à condição anaeróbica, o O MFC não conseguiu remover os nutrientes. Além disso, um teste de toxicidade aguda com Lactuca sativa revelou que o MFC poderia reduzir a toxicidade das águas residuais. Estes resultados demonstraram que o MFC ampliado poderia ser operado como um tratamento de efluentes primários e transformar uma estação de tratamento de águas residuais (ETAR) numa fonte de energia renovável produtor. |
| Abstract: | Microbial fuel cell (MFC) operation under similar conditions to conventional methods will support the use of this technology in large-scale wastewater treatment. The operation of scaled-up air-cathode MFC (2 L) fed with synthetic wastewater (similar to domestic) in a continuous flow was evaluated using three different hydraulic retention times (HRT), 12, 8, and 4 h. We found that electricity generation and wastewater treatment could be enhanced under an HRT of 12 h. Additionally, the longer HRT led to greater coulombic efficiency (5.44%) than MFC operating under 8 h and 4 h, 2.23 and 1.12%, respectively. However, due to the anaerobic condition, the MFC was unable to remove nutrients. Furthermore, an acute toxicity test with Lactuca sativa revealed that MFC could reduce wastewater toxicity. These outcomes demonstrated that scaled-up MFC could be operated as a primary effluent treatment and transform a wastewater treatment plant (WWTP) into a renewable energy producer. |
