【 摘 要 】

The use of volatile fatty acids (VFAs) as process indicators in anaerobic digestion of FW was studied. In this paper, the anaerobic digestion of food waste (FW) at 37? under quasi-continuous conditions was described. The aim of this work is to determine a reliable parameter which could be used as an indicator of process imbalance during anaerobic digestion of FW. The results showed that VFAs change constitutes the most important indicator of early warning of process imbalances during anaerobic digestion of FW. During the recovery of the process, propionate could best describe the normalizing of the process.
