摘　　要：利用聚磷菌在缺氧条件下的吸磷和反硝化作用,实现氮、磷的同时去除,是具有实用前景的城市污水处理方法,而建立活性污泥法脱氮、除磷的数学模型则有利于该项技术的推广应用。文中对ASM2d模型、BarkerandDold模型、Delft模型作了较为详细的介绍,提出了由聚磷菌引起的缺氧吸磷和反硝化作用中需要解决的2个问题:反硝化聚磷菌浓度的确定和由反硝化聚磷菌吸磷所引起的磷的减少量。The use of the phosphorus uptake and denitrification of PAOs under anoxic conditions for the realization of the simultaneous removal of nitrogen and phosphorus is a method with practical prospect for municipal sewage treatment, and the establishment of the mathematical models of denitrification and dephosphorization by activated-sludge process benefits the popularization and application of this technology. Models ASM2d, Barker and Dold and Delft are presented in a detailed way in this paper, with two issues raised which need to be resolved in the anoxic phosphorus uptake and denitrification caused by PAOs, i.e. the determination of the concentration of denitrification PAOs and the decrease of phosphorus caused by the phosphorus uptake of denitrification PAOs.
