| 摘 要： | 为了考察长期低聚磷(Poly-P)条件下Accumulibacter的菌群结构及其代谢特性的变化,采用两个SBR反应器,分别采用乙酸钠和丙酸钠为有机碳源,接种富含Accumulibacter的活性污泥,在进水PO34--P浓度为2. 5 mg·L~(-1)的低磷进水条件下运行60 d,对系统除磷性能、污泥浓度、主要菌群结构的变化进行研究.结果表明,长期低Poly-P条件下两个SBR系统均表现出良好的除磷和去除有机物的性能,但两个系统内的菌群代谢均表现出聚糖菌代谢特征;运行60 d后,丙酸盐系统中AccumulibacterⅠ型仍保持了较高的丰度(40%±7%),表明丙酸盐SBR系统中AccumulibacterⅠ型不仅具有较高的代谢活性,还能够在长期低聚磷条件下以一种不依赖Poly-P的代谢方式进行生存;对比发现,丙酸盐碳源更有利于Accumulibacter适应低磷负荷的运行环境,且在低磷负荷的运行环境下AccumulibacterⅠ型比Ⅱ型更具竞争优势.
