Therefore, it is a very worthy subject of study. In this study investigated the methane production by anaerobic co-digestion swine manure with rice straw. Mainly the parameter are temperature(40 ℃、55℃) and inoculum(improved number 1、improved number 2、improved number 3) to investigated the effect of methane production, and find the optimal operating condition to produce methane by anaerobic digestion with above two experiments. Finally,investigated the effect of swine manure(SW) with rice straw(RS) at three different SW to RS volatile solid ratio of 3:1, 1:1, 1:3 by optimal operating condition. The results indicate that, the cumulative methane production was 3328.49 54.51 mL under the condition of temperature at 55℃ and add inoculum of improved number 3, and the cumulative methane production was the best. Cumulative methane production was 3745.11 79.54 mL under volatile solid ratio at 3:1 was the best in the experiment of different volatile solid ratio.
