Abstract

Abstract

Food waste (FW) and waste-activated sludge (WAS) were utilized to study the effects of different FW proportions (0%, 25%, 50%, 75%, and 100%) on the performance of anaerobic co-fermentation (Co-AF) for volatile fatty acids (VFAs) synthesis during 16 days. The results demonstrated that injecting FW increased Co-AF performance by promoting organic matter decomposition, balancing the system’s C/N ratio, and delivering critical nutrients. When the FW ratio was 50%, the maximum VFA yield was (282.8±2.9) mg COD/g VSS. The abundance of acidogenic bacteria (Prevotella_7, Lactobacillus, Veillonella) increased steadily during the co-fermentation period, the activities of hydrolytic and acidogenic enzymes were inhibited early but recovered later, and methanogenic enzymes were inhibited throughout the period, which promoted VFA accumulation. This research could promote the utilization of WAS and FW through the Co-AF process.
