DAMO过程中甲烷传质模型的建立与验证
Establishing and verifying of model for methane mass transfer in DAMO process
摘要
Abstract
Denitrification anaerobic methane oxidation (DAMO) is a discovery in environmental science and engineering field. DAMO process releases a large of free energy, but DAMO microbial growth is extremely slow. The doubling time is as long as one month or more, which makes it difficult to attain DAMO enrichment culture. Methane is thought to be the key element on DAMO bacteria enrichment, because it is insoluble in water. A mathematical model describing methane behavior in gas-liquid-bacteria phases was set up to study the effect of methane on DAMO bacteria enrichment. Based on the model analysis, a relational expression between DAMO specific activity, methane partial pressure in gas phase and resistance of mass transfer was obtained, which was confirmed by DAMO specific activity test.关键词
