上向流式反硝化滤池在高含氮城镇污水处理厂提标改造工程中的设计与运行实践

Design and Operation Practice of Upflow-denitrification-filter in Reconstruction Project of Wastewater Treatment Plant with High Nitrogen Content

反硝化滤池(DNF)是近些年国内污水厂一级A提标改造中经常采用的深度处理工艺,目前反硝化滤池大部分采用下向流,以专有技术提供为主,既有国内的技术提供商,也有国外的几个专利技术池型,实践层面国内还缺乏设计规范。因此,提出了上向流式反硝化滤池在湖北省某高含氮污水处理厂的设计与运行实践,供同类型项目的设计及运营提供借鉴。

Denitrification filter(DNF) is an advanced treatment process often used in ‘Level I.a Standard’ improvement of domestic sewage treatment plants in recent years. At present, most of the denitrification filters adopt downward flow, which is mainly provided by proprietary technology, and there are domestic technology providers. There are also several patented technology pool types in foreign countries, and there is still a lack of design specifications at the practical level. Therefore, the design and operation practice of upflow denitrification filter in a high nitrogen wastewater treatment plant in HubeiProvince is put forward, which can be used as a reference for the design and operation of the same type of WWTP.
