摘　　要：强化生物除磷工艺具有运行灵活、可持续、除磷效果好的优点,在城市污水处理厂得到广泛应用,已经成为污水除磷的首要选择。但硝酸盐的存在会影响活性污泥系统中聚磷菌的厌氧释磷过程,导致强化生物除磷工艺很难满足地表Ⅳ类水标准。基于此,文章以某市污水处理厂为例,在简述该处理厂概况的基础上,重点探究硝酸盐对强化生物除磷效果的影响特性,为城市污水处理厂的平稳运行提供参考。The enhanced biological phosphorus removal process has the advantages of flexible operation,sustainability,and good phosphorus removal effect.It has been widely used in urban sewage treatment plants and has become the primary choice for wastewater phosphorus removal.However,the presence of nitrate can affect the anaerobic phosphorus release process of polyphosphate accumulating bacteria in the activated sludge system,making it difficult for the enhanced biological phosphorus removal process to meet the Class Ⅳ surface water standard.Based on this,this article takes a sewage treatment plant in a certain city as an example,briefly describes the overview of the plant,and focuses on exploring the impact characteristics of nitrate on enhancing biological phosphorus removal efficiency,providing reference for the smooth operation of urban sewage treatment plants.
