摘　　要：天津市宁河区城市污水处理厂现状工程规模为6×10~4m^3/d。其中一期工程规模为3×10~4m^3/d,采用厌氧+百乐克工艺,二期工程规模同为3×10~4m^3/d,采用多模式AAO工艺。本次改造工程出水标准由一级A排放标准提升至天津市地标A标准,工程中拆除一组百乐克生物池,新建多级AO生物池,同时新建反硝化滤池和臭氧催化氧化池作为深度处理工艺,实现整体提标。由于新建的多级AO生物池与二期多模式AAO池设置在一个厂内,两者设计规模、进水水质完全相同,具有很好的对比条件,由此,对项目设计参数和运行数据进行了详细总结。从运行效果看,多模式AAO工艺除磷效果占优,多级AO工艺脱氮效果占优,工程所积累的宝贵经验对两种工艺的发展和推广具有十分重要的促进作用。The treatment capacity of Tianjin Ninghe Municipal Wastewater Treatment Plant was 6 ×104m3/d. The scale of the first phase project was 3 ×104m3/d and anaerobic ＋ BIOLAK process was applied. The scale of the second phase project was also 3 ×104m3/d and the muhi-mode AAO process was applied. The standard of effluent in the wastewater treatment was required from class A of national discharge standard to class A of Tianjin local limit. In the renovation project, one BIOLAK treatment stage was replaced by multistage AO, and the denitrificafion deep-bed filter and ozone catalytic oxidation process were constructed as advanced treatment process. The new multistage AO biological process has the same design scale and the standard of influent as multi-mode AAO process. So these two process have good contrast conditions. In this project, the design parameters and running data were summarized in detail. The effect of phosphorus removal in the multi-mode AAO process was better and nitrogen removal in the multistage AO process was better. The valuable experience accumulated in the project will be of great importance to the development and promotion of the multistage AO and multi-mode AAO process.
