摘　　要：随着污水排放标准的日趋严格,反硝化滤池的应用越来越广泛,工程应用中可实现出水TN≤5 mg/L。文章综述了反硝化滤池的标准规范、研究和工程应用,综合分析了滤料、碳源、过滤流向等主要设计参数,对不同应用场景下滤料、碳源、流向的选择提出建议。建议在二级处理时采用上向流陶粒滤池,在深度处理时采用下向流石英砂滤池,为城镇污水处理厂反硝化滤池的设计运行提供参考。With the improvement of national wastewater discharge standards,denitrification filters are widely used in urban wastewater treatment plants(WWTPs),which can achieve effluent TN concentration of less than 5 mg/L.This paper reviews design specification,research and engineering application of denitrification filter,where main process parameters,such as filter media,carbon sources,flow directions,are discussed.As for the selections of filter media,carbon sources and flow directions in different application of denitrification filters,it is recommended to use an up-flow filter with ceramsite for secondary treatment,and a down-flow filter with quartz sand for advanced treatment,which can provide reference for the design and operation of denitrification filter in WWTPs.
