摘　　要：以四川省岷江流域某污水处理厂一期工程为例,介绍了项目的工艺流程及设备参数。在一期处理水量8000 m^3/d的情况下,采用倒置A^2/O的生化处理工艺+反硝化深床滤池的深度处理工艺使出水水质达到四川省岷江、沱江流域水污染排放标准(DB 51/2311-2016),其中COD、BOD5、SS、TN、TP去除率分别达到91.25%、97.2%、93.75%、80%、92%。Taking the first-stage project of a sewage treatment plant in Minjiang river basin of Sichuan province as an example,technological process and equipment parameters of this project were introduced.In the case of the first-stage treatment size was 8000 m^3/d,the biochemical treatment process of reversed AAO and deep processing technology of denitrification biofilter made the effluent quality met the standards for discharge of water pollution in mingjiang tuojiang river basin(DB 51/2311-2016).The removal rate of COD,BOD5,SS,TN and TP reached 91.25%,97.2%,93.75%,80%and 92%respectively.
