Abstract
A comprehensive literature review was conducted on psychrophilic anaerobic digestion and design of anaerobic digesters for treating animal manures. Anaerobic digestion of caged layer manure was studied in the laboratory at low temperatures (14–23°C). The digesters were operated to determine combinations of temperature and loading rate that gave acceptable methane yield. Acceptable methane yield was obtained for loading rates ranging between 0·15 kg VS/m day and 0·57 kg VS/m3 day for temperatures of 14°C and 23°C, respectively. The resulting data along with that taken from similar tests documented in the literature was found to approximate the van't Hoff-Arrhenius equation. This equation is then suggested as a technique for determining suitable loading rates for psychrophilic digesters based on data for digesters operated at higher temperatures.
对动物粪便的厌氧消化及厌氧消化池的设计进行了综述。在实验室低温(14-23℃)条件下，研究了笼养蛋鸡粪便的厌氧消化。操作消化器以确定温度和加载速率的组合，从而产生可接受的甲烷产量。在温度为14°C和23°C的条件下，加载速率分别为0.15 kg VS/m天和0.57 kg VS/m3天，甲烷产量可接受。结果数据以及从文献中记录的类似测试中获得的数据被发现近似于范霍夫-阿伦尼乌斯方程。然后，根据在较高温度下操作的蒸煮器的数据，建议将该方程作为确定适宜的装载率的技术。
