Abstract

Solar energy is infinite and environmental-friendly energy that is widely used in many fields such as solar cells, solar roofs, solar dryers and so on. However, solar energy has never been used in anaerobic digestion processes for biogas production. The use of solar energy may accelerate the biogas reaction to achieve higher gas production rates. Hence, the purpose of this research was to study a two-stage anaerobic digestion system in combination with a greenhouse solar dryer to increase the rate of biogas production. The study consisted of two parts: the first was to study the temperature variations in greenhouse solar dryers using computational fluid dynamic techniques, and the second was to conduct two-stage anaerobic digestion integrated with the greenhouse solar dryer system for biogas production. The results showed that the average temperature and biogas production rate in the integrated two-stage anaerobic digestion system compared to a conventional system increased by 16.2% and 19.69 %, respectively

两段厌氧消化与温室太阳能干燥器相结合提高沼气产量的新方法

太阳能是一种无限的环保能源，广泛应用于太阳能电池、太阳能屋顶、太阳能烘干机等领域。然而，太阳能从未用于沼气生产的厌氧消化过程。太阳能的使用可以加速沼气反应以实现更高的气体生产速率。因此，本研究的目的是研究一种两阶段厌氧消化系统与温室太阳能干燥器相结合，以提高沼气产量。该研究由两部分组成：第一部分是使用计算流体动力学技术研究温室太阳能干燥器的温度变化，第二部分是与温室太阳能干燥器系统集成进行两阶段厌氧消化以生产沼气。结果表明，与传统系统相比，一体化两级厌氧消化系统的平均温度和沼气产量分别提高了16.2%和19.69%
