Abstract:Current detection methods for the heating value of sludge generally require advanced apparatus, complicated measurement steps and long detection time. In order to avoid these problems a novel detection system based on microbial fuel cells was proposed to determine the heating value of sludge in this study. The feasibility of the detection system for the heating value measurement was evaluated. Results showed that the MFCs functioned well when sludge was used as the substrate. High power outputs were obtained under the optimal external resistance (300Ω). The MFCs could start-up quickly (within 2~14h) and run steadily for over 56h with a maximum current output. The heating value of sludge showed a significant linear correlation with the current output of MFC. According to this corresponding relationship, an estimation formula for the heating value of sludge was established, so the heating value of sludge can be predicted accurately.
