A study on the mechanism of biological removal of phosphorus: Microbial composition of the activated sludge in a sequencing batch reactor



A study on the mechanism of biological removal of phosphorus: Microbial composition of the activated sludge in a sequencing batch reactor



Chinese Journal of Environmental Science (Beijing) 13(4): 2-4



In this paper, the microbial composition of the activated sludge in a sequencing batch reactor, which can effectively remove phosphates from waste water, was investigated. Experimental results demonstrate: (1) The population of bacteria in the mixed liquor of activaged sludge during steady operation stage was much larger than that during the start-up stage (about 26 times larger). (2) The predominant genus during the start-up stage was Aeromonas and Pseudomonas came second (with no Acinetobacter found), while the predominant genera during the steady operation stage were Pseudomonas and Aeromonas (with a limited number of Acinetobacter present).
