宿州市城南污水处理厂一期提标改造工程设计

Design of First-phase Upgrading and Reconstruction Project of Chengnan Municipal Wastewater Treatment Plant in Suzhou City

介绍了宿州市城南污水处理厂一期提标改造工程技术路线及方案。结合污水厂运行现状,依据充分利用现状处理设施、施工期间不影响生产的原则,采用增加分点进水厌氧—好氧—缺氧活性污泥法(简称改良AOA工艺)的生物反应池,并增设过滤及消毒设施,确保出水水质稳定达标排放。该提标改造工程自建成投运以来,处理效果稳定,出水水质稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A排放标准。

The technical route and scheme of the first-phase upgrading and reconstruction project of Chengnan WWTP in Suzhou City were introduced. Combined with the actuality of the WWTP, accord- ing to the principals of making full use of the current treatment facilities and not influencing the produc- tion during the construction, some measures, including adding step-feed anaerobie/aerobic/anoxic acti- vated sludge biological reaction tank, filtration and disinfection facilities, were taken to ensure the efflu- ent quality to meet the discharge standard. Since being put into operation, the upgrading and reconstruc- tion project has achieved the stable treatment effect, and the effluent indexes meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 - 2002）.
