中文摘要:为开发禽畜废水厌氧处理技术,利用外循环反应装置开展了畜禽废水厌氧反应动力学研究,以温度、基质COD值以及pH值为因素,设计了三因素三水平正交试验;引入温度参数,改进了Monod方程,建立了基质消耗、产物生成动力学模型;经线性、非线性回归,获得了模型参数,建立了相应的动力学方程,揭示了反应温度、基质COD值对反应速率的影响规律。研究表明:对基质消耗速率而言,反应活化能很低,可以忽略温度对反应速率的影响;温度对产物CH4和CO2的生成反应速率有影响,温度越高,越有利于CO2的生成。建立的禽畜废水厌氧反应动力学模型能够较好地拟合试验数据,对厌氧反应器的开发设计具有参考价值。

Abstract:With the rapid development of economy and improvement of people’s living standard, aquaculture was developed rapidly over the past years. And a large amount of livestock wastewater was produced meanwhile. Thus effective treatment of livestock wastewater becomes the much urgent problem to be solved. Anaerobic treatment technology is recognized as one of the most promising wastewater treatment technologies in environmentally sustainable development. The design of anaerobic reactor is the key for developing anaerobic treatment technology of livestock wastewater. In order to describe and simulate the process of anaerobic reaction, guide the optimization of process parameters and design of reactor in the practical production, the kinetic model of livestock wastewater was established. The experiments were carried out in an external loop reactor. The orthogonal experiments with three factors and three levels were designed by taking temperature, matrix COD and pH value as factors. Temperature parameters were introduced to improve the Monod equation, and the dynamic models of matrix consumption and product formation were established. By linear and nonlinear regression, the model parameters and the corresponding dynamic equations were established, and the effects of reaction temperature and substrate concentration on reaction rate were revealed. The results showed that the reaction activation energy was very low, and the effect of temperature on reaction rate could be neglected. Temperature could affect the production rate of CH4 and CO2. The production of CO2 would be increased with the increase of temperature. The new livestock wastewater anaerobic reaction dynamics model could fit the experimental data well, which had positive significance for the development and design of new anaerobic reactor.

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.
