摘　　要：以某城镇污水处理厂为例,介绍了该污水处理厂的项目概况及提标改造的设计内容。该污水厂提标改造主体工艺为AO工艺+悬浮填料,本次改造在不增加生物反应池容积的前提下,通过重新划分缺氧好氧段、改造曝气系统、回流系统、更换填料及新增碳源投加系统、次氯酸钠消毒设施使出水水质基本达到设计要求。该改造工程可以为污水处理厂的提标改造设计提供借鉴参考。An urban sewage treatment plant as an example,the project overview and design content of upgrading and renovating the sewage treatment plant were introduced.The main process of upgrading and renovating the sewage treatment plant was the A/O process and suspended filler.And this renovation does not increase the volume of the biological reactor on the premise of redividing the anoxic aerobic section,renovating the aeration and reflux systems,replacing the filler and adding a carbon source feeding system and sodium hypochlorite disinfection facilities to make the effluent quality basically meet the design requirements.The renovation project can provide a reference for the design of upgrading wastewater treatment plants.
