In order to investigate the composition and function of the microbial community under stable operation, metagenomic analysis was used to further analyze the samples from anoxic tank, aerobic tank filler and aerobic tank in this wastewater treatment system. Taxonomic analysis showed that the dominant bacterial phyla were Proteobacteria, Actinobacteria and Chloroflexi. The dominant polyphosphate accumulating organism (PAO) found were Accumulibacter (0.81%-0.99%), Tetrasphaera (0.35%-0.75%) and Mycobacterium (1.00%-1.54%). The relative abundance of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) bacteria were enriched in aerobic biofilm, and the typical AOB and NOB were Nitrosomonas (2.8%) and Nitrospira (2.8%), respectively. The denitrification functional bacteria detected mainly included Dechloromonas, Flavobacterium and so on. Otherwise, various key enzymes related to nitrification, denitrification and Anammox during nitrogen removal were annotated and quantified.类似文献/References:[1]张玲玲,曹洋,顾淼,等.高排放尺度下城市污水深度脱氮手艺研究[J].中国给水排水,2021,37(13):27.
