摘要
通过对北京协和医院污水站改造进行实例分析,对比研究改造前后一级处理工艺和膜生物反应器(MBR)处理工艺的出水水质,从方案选择、工艺流程和设备选型等方面研究MBR处理工艺在综合医院污水处理的应用。结果表明,改造后的MBR处理工艺在化学需氧量、生物需氧量、悬浮物及氨氮的去除率均有显著提高,出水可满足稳定达标排放要求。由此得出,MBR处理工艺具有出水水质好、设备紧凑、占地小等优点,在医院污水站改造条件有限且对出水水质要求严格的情况下,建议采用该工艺。
Based on the space conditions and sewage treatment requirements of Peking Union Medical College Hospital,four sewage stations with first-grade treatment system were re-constructed using membrane bioreactor(MBR)treatment process.This paper reported the scheme selection,process flow and equipment selection.It shows that MBR treatment process is characterized by good effluent quality,compact equipment,small footprint and other advantages.It is worthy to recommend in other hospitals to support sewage station transformation.
