Abstract

The performance and the characteristics of a laboratory scale anaerobic baffled reactor (ABR) were investigated using synthetic wastewater. The experimental results showed that among different volatile fatty acids (VFAs), acetate was the main intermediate of acidogenic degradation of glucose. The VFA concentration decreased longitudinally down the reactor. The analysis of the biogas composition revealed that methane concentration increased steadily from compartment 1 to 5, while hydrogen content decreased in the first compartments. There was no detectable hydrogen in the last two compartments. The methane-producing activity of anaerobic sludge in different compartments depended on the substrate, which suggests that the proper anaerobic consortium in each separate compartment was developed according to the substrate(s) availability and the specific environmental conditions. The ABR has the potential to provide a higher efficiency at higher loading rates and be applicable for extreme environmental conditions and inhibitory compounds.

摘要

采用合成废水对实验室规模的厌氧折流板反应器（ABR）的性能和特性进行了研究。实验结果表明，在不同的挥发性脂肪酸（VFA）中，乙酸是葡萄糖产酸降解的主要中间产物。VFA浓度沿反应器纵向降低。沼气成分分析表明，甲烷浓度从第1格到第5格稳步增加，而氢气含量在前面几个格中降低。最后两格中未检测到氢气。不同格中厌氧污泥的产甲烷活性取决于底物，这表明每个单独格中都根据底物的可用性和特定环境条件形成了合适的厌氧菌群。ABR有潜力在更高的负荷率下提供更高的效率，适用于极端环境条件和抑制性化合物。
