Abstract: The influence of restaurant and kitchen waste through the pasteurization treatment on the anaerobic digestion is summarized in this paper on the basis of the experiment. Pasteurization parameters: temperature is 70℃，duration time is 10 min. Inoculum is high temperature fermentation sludge，which is cultivated by DQY’s laboratory. Feedstock is restaurant and kitchen waste. OL: 5 gVS/L ，F/M: 0.5. The experiment lasted 32 days，accumulative biogas yield of sterilized samples is 895 mL/gVS and non sterilized sample is 795 mL/gVS. The gas production rate of sterilization sample was significantly higher than that of non sterilized samples. And the VS removal rate of non sterilized sample was little higher than that of sterilization samples.

Key words: High temperature anaerobic fermentation, Restaurant and kitchen waste, Pasteurization, Efficient gas production
