Abstract

The comparative study on the microbial community structure of activated sludge from micro-pressure swirl reactor (MPSR) and SBR under stable operation was conducted by the 16S rRNA third-generation high-throughput sequencing, which was sampled from simulated domestic sewage. The experimental results indicated that the two reactors had great differences in the microbial community structure of activated sludge due to the different circulating flow patterns under the same water quality and intermittent operation mode. Compared with SBR, MPSR had more dominant bacteria phyla and some functional bacteria of higher relative abundance such as Flavobacterium and Thiotrix, and simultaneously strictly anaerobic, strictly aerobic and facultative anaerobic microbial species existed so as to produce higher species diversity and population richness, which is accord with the polyphase theory of the reactor.
