Abstract:Shii-take cultivation waste (SCW) was used as rich carbon material for anaerobic digestion under the mesospheric condition as (35±1)℃. Orthogonal test and regression analysis L9(33) were employed to determine the effects of the three factors including pretreatment period, inoculums concentration and total solids (TS) on biogas production. The optimal combination of the three factors has been achieved. The high-carbon content material was proved to be not an ideal feedstock for biogas production. However, after a certain period of pretreatment, the high carbon feedstock biogas production was improved a lot. The biogas production reached to 0.16L/g(TS), increased by 128.57% compared with the control sample. The sequence of factors effecting SCW anaerobic fermentation is pretreatment period (evident), TS (evident), and inoculums concentration (less evident). A multiple regression equation was established and can be used for biogas production prediction under different conditions. |
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.
