Objective] To study the effect of different temperature hot water immersion degreasing on biogas production amount of food waste by anaerobic digestion.[Methods]Under the condition of 40℃,through anaerobic fermentation experiments,after different temperature hot water immersion to degrease,gas production potential of kitchen waste by anaerobic digestion was analyzed. [Results] The hot water eliminating the oil treatment can reduce fat content of kitchen trash,enhance pH value and promote hydrolisis rate;Under the normal temperature(25℃),60℃,80℃and 100℃,after hot water immersions,the unit volatile solid(VS)potential produced by kitchen trash were 745 mL/g,557 mL/g,603 mL/g and 646 mL/g respectively;along with the increasing of temperature of hot water for degrease,degrades rate of the total solid and the volatile state system of kitchen trash increased. [Conclusion] The hot water immersion eliminates the oil is possible to enhance the hydrolisis rate of kitchen trash,and improve the potential of biogas production.
