Abstract

Abstract

To understand the microbial community structure of activated sludge wastewater treatment plants (WWTPs) in arid and cold regions of Xinjiang, illumina high throughput sequencing technology was used to analyze the microbial community structure of activated sludge from five WWTPs in northern Xinjiang. The results showed that all of the WWTPs could basically reach their respective effluent standards, and three of them occurred filamentous sludge bulking. Proteobacteria, Bacteroidetes and Chloroflexi were the dominant bacterial phyla of activated sludge, comprising 30.65%~43.12%, 21.15%~33.64% and 5.02%~14.36% of the total abundance, respectively. The relative abundance of Actinobacteria was 2.97%~6.17% in non~bulking sludge and was 11.69%~15.64% in bulking sludge. The relative abundance of Microthrix and Flavobacterium in seasonally bulking sludge showed seasonal changes. Saprospiraceae_norank was the dominant genus in the perennial bulking sludge, with the relative abundance reaching 17.48%~18.30%. Ascomycota was the dominant fungal phylum in filamentous sludge bulking, with a relative abundance of 56.60%~72.68%. The research results could provide theoretical support for the operation regulation of WWTPs in arid and cold regions.
