摘要

This study investigates the influence of low temperature thermo-chemical pretreatment of diary wasteactivated sludge on the performance of microbial fuel cell. First, effect of sludge pretreatment wasevaluated by Chemical Oxygen Demand (COD) solubilization and suspended solids (SS) reduction. Atoptimized condition (70C for 24 hr), COD solubilization and SS reduction was 29% and 24% higherthan control. Second, with 20 days operation at batch mode, H- type microbial fuel cell (MFC) was runwith raw and pretreated sludge (external resistance - 300. Low temperature thermo-chemicalpretreatment improved the Total Chemical Oxygen Demand (TCOD) removal and SS reductionefficiency in the microbial fuel cell up to 54% and 43%, gaining an overall efficiency of 54% TCOD3 removal and 50% reduction in SS. The power density of the MFC had increased from 0.5W/m (raw3 sludge) to 0.715W/m (pretreated sludge). Thus, by combining this pretreatment with MFC, renewableenergy could be generated from sludge in addition to treatment.
