Abstract
The heating value of sludge is an important index for the combustion characteristic and energy utilization value of sludge. However, current detection methods for heating value generally require complicated apparatus, complicated measurement steps and long detection time, making them difficult to be practically applied in wastewater treatment plants. In the present study, a novel detection system based on microbial fuel cells was established to determine the heating value of sludge. Four sludges from different wastewater treatment plants were employed to investigate the feasibility of the detection system for heating value measurement. Results showed that the MFC functioned well when using sludge as the substrate. High power outputs were obtained under the optimal external resistance (300 Ω). The MFC can start-up quickly (within 2~14 h) and run steadily for over 56 h with a maximum currentoutput. The heating value of sludge showed a significant linear correlation with thecurrentoutput of MFC. According to this relationship, an estimation formula for the heating value of sludge was established, so the heating value of sludge can be predicated accurately. The detection system developed in this work has the advantages of easy operation, low cost and short detection time, thus is promising to be applied in wastewater treatment plants for the detection of sludge heating value.
