碳源类型对AOA-SBR系统的除磷特性和菌群组成的影响
Effects of carbon sources on phosphorus removal characteristicsof anaerobic-oxic-anoxic(AOA)-SBR systems
摘要
Abstract
To investigate the influence of different carbon sources (acetate and propionate) on the phosphorus removal properties and the microbial community structure of polyphosphate accumulating organisms, two sequencing batch reactors (SBR) were operated under anaerobic-aerobic-anoxic (AOA) conditions.After 25 days acclimation, both of the two systems showed the stable phosphorus removal performance.During the stable phase, the phosphorus removal rates of the two systems were 88％ and 97％, respectively.The sludge acclimated with acetate had a good settle ability and the slow proliferation.On the other side, the propionate system had the better phosphorus removal performance, faster growth rate, but had the poor sedimentation.Fluorescence in situ hybridization (FISH) confirmed that both of the two reactors created a great quantity of Accumulibacter.Most of Accumulibacters in acetate system were type Ⅱ, and in the propionate system, the Accumulibacters were mainly type Ⅰ.关键词
