低温下固定床反应器碳纤维载体对产甲烷特性的影响研究
Methane of Characteristics by Carbon Fiber Carrier in Fixed bed Anaerobic Reactor at Low Temperature
摘要
Abstract
In order to explore how to achieve efficient anaerobic methanogenesis at low temperatures,this study utilized a fixed-bed reactor.By externally adding the methanogenic strain BDP-8 and adjusting the density of the carbon fiber carrier,the gas production efficiency of the fixed-bed reactor at low temperatures was evaluated based on indicators such as gas pro-duction volume,methane content,pH value,volatile fatty acid content,and COD removal rate.The results showed that when the bacterial suspension concentration was 30％and a carbon fiber membrane with a mass fraction of 5.25％was add-ed,the optimal gas production efficiency was achieved.The cumulative gas production volume reached 559 mL,the pH value fluctuated within a narrow range,the volatile fatty acids were effectively degraded,and the COD removal rate reached 93.48％.These findings demonstrate that the appropriate addition of the selected methanogenic strain and carbon fiber membrane in a fixed-bed anaerobic reactor at low temperatures can significantly enhance the methanogenesis process.关键词
