中文摘要:研究了牛粪原料高温(55℃)干式厌氧发酵过程中产气效果和物料参数的变化规律。结果表明:接种比例3∶10、8r/min连续搅拌条件下,物料TS(总固体)产气率为311mL/g,甲烷平均体积分数为57.1%,平均容积产气率为2.73L/(L·d);容积产气率在第3天达到最高,为5.23L/(L·d);反应初期挥发性脂肪酸迅速积累,1d后即达到峰值,随后迅速减少;在反应初期pH值略有下降,随后逐渐升高;氨氮质量浓度和总碱度则一直呈上升趋势。

Abstract:Dry anaerobic digestion of dairy manure under thermophilic temperature (55℃) for biogas producing was investigated, including the effect of different inoculation ratios on biogas producing, and the changes of biogas and methane producing, pH value, concentrations of ammonia, volatile fatty acid and total alkalinity during digestion. Inoculated dairy manure (the ratio of inoculums and dairy manure was 3∶10) was anaerobic digested 15 days under continuous mechanized mixing (8r/min), and total solid biogas production, average daily biogas production, the maximum daily production and the average content of methane reached to 311mL/g, 2.73L/(L·d), 5.23L/(L·d) (3rd day) and 57.1%, respectively.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
