七格污水处理厂提标改造工程设计

Design of Upgrading and Reconstruction Project of Qige Wastewater Treatment Plant

介绍了七格污水处理厂一、二、三期提标改造工程改造前后的处理工艺、设计参数和运行状况,提标改造工程均采用深床滤池工艺,并对原生物反应池、污泥回流系统、除臭系统等进行了技术改造。改造后出水水质可稳定达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准,可为同类污水处理厂升级改造提供参考。

The treatment processes, design parameters and operating status in Qige WWTP first-,second- and third-phase projects before and after the upgrading and reconstruction were introduced. Deepbed filter technology was used for upgrading and reconstruction, and the original biological reaction tank,sludge return system and deodorization system were technically reconstructed. After the reconstruction,the effluent quality could meet the first level A criteria specified in the Discharge Standard of Pollutantsfor Municipal Wastewater Treatment Plant （GB 18918 -2002）. The project can provide reference for theupgradingand reconstruction of similar sewage treatment plants.
