BAF工艺在污水厂提标改造中的应用
- Title:
- Application of BAF Process in Upgrading and Reconstruction of a WWTP
- 摘要:
- 北京某污水处理厂提标改造工程设计规模为5×104 m3/d,主要目标为去除氮、磷及有机物,结合提标出水水质要求,在现有循环式活性污泥法(C-Tech)处理工艺不变的基础上采用曝气生物滤池(BAF)作为深度处理工艺,新建水质调节池、生物滤池、滤布滤池、紫外消毒渠、加药间、污泥脱水机房。提标改造后出水水质均达到北京市《城镇污水处理厂水污染物排放标准》(DB 11/890—2012)的B级标准。
- Abstract:
- The design capacity of the upgrading and reconstruction project of a WWTP in Beijing is 5×104 m3/d. The main goal is to remove nitrogen, phosphorus and organic matter. According to the effluent quality requirements, biological aerated filter is used as the advanced treatment process based on the existing C-Tech treatment process. Water quality regulating tank, biological filter, cloth media filter, UV disinfection channel, dosing room, sludge dewatering room were newly constructed. After upgrading, the effluent quality all meet the level B criteria of Discharge Standard of Water Pollutants for Municipal Wastewater Treatment Plants (DB 11/890-2012).
