摘　　要：目前工程实践中强化生物除磷(EBPR)仍以活性污泥工艺为主,生物膜工艺的EBPR还处于研究阶段。基于对生物膜实现EBPR基本条件的分析,提出了要实现生物膜EBPR至少要解决的三个问题:反应器构型的优化选择,运行模式的变换与运行周期的优化设定,以及要解决富磷污泥的排放与持留之间的矛盾问题。介绍了若干利用生物膜工艺实现EBPR的典型工艺路线及处理效果,以期为今后高效生物膜反应器EBPR的开发与研究提供借鉴。At present, activated sludge process plays a main role in enhanced biological phosphorous removal （EBPR） and the biofilm process is still under researching. Based on the systematical analysis of biofilm aiming at EBPR, it is proposed that three problems must be solved firstly. They are. adjusting the bioreactor configuration, transforming the operation mode and optimizing the operation period, and balancing the discharging and holding of the phosphorous-rich biomass. In this paper, some typical biofilm EBPR process routes and effectiveness are introduced aiming at giving some possible help for the developing and researching of high performance EBPR in biofilm reactor.
