英文摘要	Four 30 L anaerobic fermentation reactors were used for dry fermentation of food waste under medium temperature of 37 degrees C. A comparative experiment was performed between anaerobic and micro-aerobic reactors. Differences in concentrations of volatile fatty acids (VFAs), COD, ammonia nitrogen, and methane yield were compared under a micro-aerobic environment. The influence mechanism of micro-oxygenation treatment on anaerobic fermentation was discussed. The results indicated significant changes in the concentrations of VFAs, COD and ammonia nitrogen under different environments. As the fermentation system stabilized, VFAs concentration increased from 27.5 g/L in an anaerobic system to 28.3 g/L in a micro-aerobic system; COD concentration increased from 58400 mg/L in an anaerobic system to 59450 mg/L in a micro-aerobic system; ammonia nitrogen concentration increased from 1632 mg/L in an anaerobic system to 1699 mg/L in a micro-aerobic system; cumulative methane yield increased from 138.02 L in an anaerobic system to 139.91 L in a micro-aerobic system. These data indicated that micro-oxygenation treatment activated aerobic and facultative anaerobic microorganisms in the system, thereby facilitating their participation in the hydrolysis acidification of macromolecules. In the process of microbial fermentation, VFAs and other organic matters is the main raw material for microbial fermentation As the concentrations of VFAs and other organic matters increased, the micro-oxygenation system has more energy sources available for methanogens to produce methane, that's the main difference between anaerobic and micro-aerobic system.
