摘　　要：强化生物除磷(enhanced biological phosphorus removal,EBPR)工艺在废水除磷处理中应用广泛.主要功能微生物及其代谢机理的研究是有效调控EBPR工艺稳定运行与效能提升的基础.本文选取EBPR系统中最主要的两类微生物(聚磷菌和聚糖菌),从底物吸收机制、糖酵解途径、TCA途径的贡献以及聚磷菌和聚糖菌的代谢相似性等方面对这些微生物的代谢机理进行综述,评价了分子生物学技术在研究EBPR系统微生物学及其代谢机理方面的应用现状,在此基础上对EBPR系统今后的研究方向进行了展望.Enhanced biological phosphorus removal （EBPR） process is applied widely for removing phosphorus from wastewater. Studies on functional microorganisms and their metabolic mechanisms are fundamental to effective regulation for stable operation and performance improvement of EBPR process. Two main types of microorganisms in EBPR systems, polyphosphate accumulating orga- nisms （PAOs） and glycogen accumulating organisms （GAQs） were selected to summarize their metabolic mechanisms such as substrate uptake mechanisms, glycogen degradation pathways, extent of TCA cycle involvement and metabolic similarity between PAOs and GAOs. Application of molecular biology techniques in microbiology and metabolic mechanisms involved in the EBPR system was evaluated. Potential future research areas for the EBPR system and process optimization were also proposed.
