摘　　要：以成都市某净水厂提标升级改造工程为例,在投资及用地受限情况下,采用多级A/O+高密度沉淀池+反硝化滤池的主体工艺,改造完成后出水水质由《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准提升为《四川省岷江、沱江流域水污染物排放标准》DB 51/2311-2016。本项目中采用的多级A/O改造模式及设计参数对未来类似工程具有指导意义,为推广多级A/O工艺提供现实价值。Taking the upgrading and reconstruction project of a wastewater treatment plant in Chengdu as an example, under the condition of limited investment and area, the main process of multistage A/O+high-density sedimentation tank+denitrifying biofilter was adopted. After the reconstruction,the effluent quality was upgraded from the first level A standard of "Discharge standard of pollutants for municipal wastewater treatment plant"(GB 18918-2002) to(DB 51/2311-2016). The multistage A/O technology and design parameters adopted in this project have guiding significance for similar projects in the future, and provided practical value for the promotion of multistage A/O technology.
