摘　　要：概述了生物除磷在厌氧、缺氧和好氧条件下的反应机理,并基于对反硝化聚磷菌的认识将现有除磷数学模型发展划分为两个阶段。基于除磷数学模拟所包含的涉磷组分、计量学参数、动力学参数以及生物衰减理论等对两阶段模型进行了较为详细的介绍和比较,认为Delft模型是现有模型中比较完善的,并提出今后发展除磷数学模型应重点解决的问题。The mechanism of biological phosphorus removal under anaerobic,anoxic and aerobic conditions is introduced.Based on understandings of denitrifying phosphorus removing bacteria,biological phosphorus removal models are divided into two stages.Based on the components,stoichiometric parameters,kinetic parameters and decay/death processes,this paper describes and compares these models in detail,considering Delft model to be validated.However,there are still some important problems needed to be solved for further development of models.
