    Abstract:

    Activated sludge is the main function body of biological treatment process in wastewater treatment plant. The species, quantity and activity of bacteria in activated sludge are the important basis for improving wastewater treatment capacity and effect. Based on the summary and analysis of the relevant literatures, the diversity and ecological characteristics of the main functional bacteria (flocculants, denitrifying bacteria, phosphorus removal bacteria, etc.) in activated sludge treatment process were summarized, and the current mainstream identification methods of bacteria were also summarized. Finally, the regulation and control of micro flora in activated sludge are discussed from three aspects: operation conditions, directional domestication and biological reinforcement, providing a certain theoretical basis for improvement of the functional stability of sewage treatment plants.
