摘要: The treatment performance and spatial microbial community structure of three parallel denitrifying biological filters (DNBFs) operated with methanol, ethanol acetate, respectively, were explored. acetate-fed DNBF presented the highest denitrification rate NOx-N (NO2-N NO3-N) removal efficiency, while methanol-fed showed lowest carbon consumption efficiency. Distinct distribution patterns terminal restriction fragment length polymorphism fingerprints observed among DNBFs. enhanced captured biofilms throughout flowpath had diversity evenness. methanol-enhanced attached biofilm along evenness, but richness limited diversity. β-Proteobacteria was dominant in all acetate biofilm; however, different external sources resulted genera species. Thauera bacterial community, both Dechloromonas that fed. However, methylotrophic bacteria (Methyloversatilis Methylotenera) dominated exclusively methanol DNBF.
