中文摘要:在前期单因素试验的基础上,采用二次回归正交旋转组合设计,以总产气量为响应值,研究餐厨垃圾与牛粪质量比、温度、pH值、接种物与原料质量比4个因素对餐厨垃圾和牛粪混合厌氧发酵的影响,建立了产气数学模型,并对模型进行了优化及降维分析。通过上述试验研究,得到最佳工艺条件为:餐厨垃圾与牛粪质量比为2.5,温度37.5℃,pH值7.0,接种物与原料质量比为4;4因素影响主次顺序依次为接种物与原料质量比、温度、餐厨垃圾与牛粪质量比、pH值;通过验证分析,模型预测值与试验值之间误差较小,方差分析不显著,模型拟合较好。

Abstract:Based on the early single factor test, quadratic regression orthogonal rotating combination design was applied. The whole gas production was taken as response value. Effects of four factors on anaerobic fermentation were studied. These four factors are the ratio of food garbage and cow dung, temperature, pH value and the ratio of inoculum and quality of fermentation. The mathematical mode about mixed fermentation of food garbage and cow dung was established, regression equation was optimized and analyzed, in addition, the optimal condition and interactive effects were exposed. The optimum technological conditions for the mixed-fermentation was as the followings: the ratio of food garbage and cow dung was 2.5, temperature was 37.5℃, the pH value was 7.0 and the ratio of inoculum volume and quality of fermentation was 4. The order of the influence of four factors on mixed-fermentation of food garbage and cow dung was as follows: the ratio of inoculum and quality of fermentation, temperature, the ratio of food garbage and cow dung, and pH value. The gas production of the optimum technological condition and the random experiment also showed no significant difference with the predictive value. The model fitted well.

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.
