何崭飞. Building and verifying of methane mass transfer model in DAMO process[J]. CIESC Journal, 2012, (6): 1836-1841.DOI: 10.3969/j.issn.0438-1157.2012.06.026.
Denitrification anaerobic methane oxidation (DAMO) is a recently discovered process 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 of methane’s behavior in gas-liquid-bacteria phases was set up to study the effect of methane on DAMO bacteria enrichment. According to the model analysis
we obtained the relational expression between DAMO specific activity
methane partial pressure in gas phase and resistance of mass transfer that was confirmed by DAMO specific activity test.
