摘　　要：增强生物除磷(EBPR)是一种高效、经济的除磷工艺,然而在某些条件下聚糖菌的过量繁殖导致除磷效果恶化。文章阐述了影响聚磷菌和聚糖菌生长的关键因素,从而可以选择性的培养聚磷菌并使其处于竞争优势,这对于提高EBPR的除磷效果、增强工艺的稳定性具有重要的意义。Enhanced biological phosphorus removal （EBPR） is accepted as one of the most efficient and economical process to remove phosphorous from wastewater. However, poor performance of EBPR has been reported resulting from proliferation of glycogen-accumulating organisms （GAO）. This paper reviews the key factors that affect the competition between phosphorus accumulating organisms （PAO） and GAO, so that favorite conditions can be adopted for the predominance of PAO in EBPR, which is important for improvement of phosphorus removal and stability of EBPR.
