In order to explore the bacterial diversity and bacterial community structure of garlic wastewater activated sludge in SBR reactor, illumina-Miseq high-throughput sequencing technology was used to analyze the bacterial community structure and diversity of garlic wastewater. The results showed that the abundance of bacteria was higher on the whole, but the diversity of bacteria was different among different samples. Bacteroidetes, Proteobacteria, Firmicutes, Actinobacteria are the dominant bacteria phyla, all of which have the function of denitrification and dephosphorization to degrade organic matter, with abundance between 6.3% and 43.72%. The five dominant genera of Macellibacteroides, Petrimonas, Rhodobacter, Fluviicola and Saccharibacteria_generaincertae_sedis in activated sludge have the functions of degrading organic matter and denitrifying, with abundances ranging from 1.81% to 21.48%. The research results can provide reference for the treatment effect of strengthening SBR reactor.
