摘　　要：我国中部某污水处理厂现状规模为3.5×10^(4) m^(3)/d,采用改良氧化沟工艺,出水执行一级B排放标准,提标扩建工程要求将现状工程出水标准提升至一级A排放标准,同时扩建3.5×10^(4)m^(3)/d,总规模达7×10^(4) m^(3)/d。为解决传统氧化沟、AAO等工艺脱氮除磷效果不佳、能耗较高、占地大等问题,本次提标扩建核心工艺采用以芽孢杆菌为优势菌的BBR工艺,该工艺为生物膜法和活性污泥法的组合技术。项目建成后系统运行稳定、效果良好、能耗低,出水各项水质指标均优于设计标准。The current scale of a wastewater treatment plant in central China is 3.5×10^(4) m^(3)/d,and the main treatment process is modified oxidation ditch.The original effluent quality was required to meet the first level B discharge standard,while the effluent quality of the upgrading and expansion project needs to meet the first level A discharge standard.Meanwhile,the scale of the expansion project is 3.5×10^(4) m^(3)/d,meaning that the total scale will reach 7×10^(4) m^(3)/d.To solve the problems such as poor nitrogen and phosphorus removal performance,high energy consumption and large footprint area of traditional oxidation ditch and AAO process,the core process of this upgrading and expansion project adopts BBR process with Bacillus as the dominant bacteria,which is a hybrid of biofilm method and activated sludge process.After the completion of the project,the system is stable and has good performance in pollutants removal and energy conservation,and all the water quality indicators of the effluent are better than the designed standard.
