In order to improve the degradation efficiency of microbial electrolysis cells (MECs) treating butyric acid fermentation broth from excess sludge, this study investigated the influence of butyrate acclimation on degradation and microbial communities, with a focus on the changes of electrochemical characteristics, gas production, organics removal, and microbial community structure. Results showed that sodium butyrate acclimation enhanced current density and gas production rate during stable operation period. Moreover, when treating butyric acid fermentation broth, the acclimated system achieved higher peak current density (19A/m3), higher oxidation peak (78.1mA), and higher organics degradation rate (SCOD removal of 58.67%; VFAs removal of 41.76%), with energy recovery attaining 118.8%. Mechanism analysis revealed that sodium butyrate acclimation effectively enriched butyrate-oxidizing bacteria (Syntrophomonas), establishing more efficient metabolic pathway in comparison with sodium acetate acclimation, thereby ameliorating the degradation of butyric acid fermentation broth.
