The biochemical methane potential（BMP） of food waste was determined in batch assays under mesophilic temperature（37 ℃） and room temperature（25 ℃） using the Automatic Gas Potential Test System（AMPTS）. The methanogenesis dynamical model of food waste under mesophilic temperature was further established. The results showed that the maximum daily methane yield and cumulative production were increased by 116.8% and 143.9% respectively under mesophilic temperature

compared to those under room temperature. The increase of temperature also helped to shorten methane production cycle and improve material degradation rate. The Cheynoweth equation was applied to simulate the process of methane production. The results showed that methane production process was highly correlated to the Cheynoweth equation with a correlation coefficient greater than 0.95

indicating that the equation could be used to describe the BMP of food waste. The results could provide theoretical applying foundation for biogas producing by anaerobic digestion with food waste.
