中文摘要:以猪粪、麦秆为原料,研究了35℃下二者按不同比例混合对厌氧消化产沼气的影响,分析了消化过程中日产气量、累积产气量、甲烷含量、原料去除率、pH值以及氨态氮质量浓度的变化。结果表明,猪粪与麦秆配比(干物质量比)1∶1时产气量最大,为383.0mL/g,是麦秆单独发酵产气量(231.8mL/g)的1.6倍;混合原料(猪粪和麦秆配比分别为1∶1、2∶1、3∶1)的VS去除率均在37%以上,比麦秆提高12.0%~26.9%;添加猪粪可提高发酵液中氨态氮含量,较麦秆提高35.6%~64.8%。因此,合理调控粪秆混合厌氧发酵的比例,能提高秸秆的产气率和利用率。

Abstract:Pig dung and wheat straw (the ratio of pig dung to wheat straw was 1∶1, 2∶1, 3∶1)were used as fermentation materials. The experiments were carried out at 35℃. The biogas production rate, cumulative biogas yield, methane content, material reduction, pH value and NH3-N content were tested. The results showed that the co-digestion of pig dung to wheat straw could increase the biogas yield and material reduction of wheat straw. The biogas production yield of 1∶1 was highest (383.0mL/g), which was 1.6 times of biogas production yield of wheat straw (231.8mL/g). VS reductions of combination materials were 12.0%~26.9% higher than wheat straw. Compared with wheat straw, the NH3-N contents of combination materials increased by 35.6%~64.8%. Reasonable co-digestion ratio of livestock dung and crop straw could increase the biogas production rate and utilization of crop straw.

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.
