Abstract:

In this study, we show that the acetic acid was mainly product, accounting for 59.83% of total VFA, propionic acid only accounting for 3.94%, composition of end products is most reasonable. Moreover, when the pH was 4∼5 in anaerobic digestion, it was beneficial to following methanogenic process. In addition, we show that the method that thermokalite pretreatment cooperated with pH controlling could promoted efficiency of acidification and optimize composition of acidification production at same time, cumulative concentration of total VFA increased by 68%, composition of end products was reasonable. Results of analysis from SEM showed that microstructure of kitchen wastes had changed obviously after thermokalite treatment. Results of kinetics analysis showed that acidogenic rate of the kitchen wastes was faster after thermokalite treatment.
