摘要: Abstract Food waste anaerobic fermentation was carried out under acidic conditions using inocula based on aerobic activated sludge (Inoculum AE) or AN) for volatile fatty acids (VFAs) production. The results showed that food hydrolysis increased obviously when Inoculum AN used relative to AE at any pH investigated. Hydrolysis 4.0 and uncontrolled higher than other pHs either inoculum used. Additionally, VFAs production 6.0 the highest, regardless of optimum VFA yields were 0.482 g/g VSS removal with 0.918 g/g VSS AN, which observed after 4 d 20 d fermentation, respectively. composition analysis butyrate acid prevalent 6.0, followed by acetate propionic acid.
