摘　　要：考察了在不同运行阶段,间歇式生物脱氮除磷处理系统内活性污泥混合蔽中细菌总数及主要细菌组成的变化特性。试验结果表明:①在稳定运行期,试验装置内活性污泥混合液中细菌总数大大多于启动期(约大26倍);②在启动运行期,活性污泥混合液中的优势菌为气单胞菌属;其次是假单胞菌属;没有发现不动杆菌属。在稳定运行期间,优势菌是假单胞菌属,其次是气单胞菌属和棒杆菌属。In this paper, the mecrobial 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 activated- sludge during steady operation stage was much larger than that during the startup stage (about 26 times larger). (2) The predominant genus during the start-up stage was aeromonas and pseudo-monas came second (with no acinetobacter iound), while the predominant genera during the steady operation stage were pseudomonas and aeromonas (with a limited number of acinetobacter present).
