重庆市沱口污水处理厂扩建工程设计
|
摘要
重庆市沱口污水处理厂一期工程采用改良型Carrousel氧化沟生化处理工艺,出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级标准的B标准。考虑到污水厂可用建设用地面积极小,二期扩建工程在充分利用原有处理设施的基础上,采用改良式Unitank生化处理工艺。该文通过对扩建工程的处理工艺以及设计参数的介绍,为占地指标要求较小的新建或者扩建工程的设计提供借鉴意义。
Tuokou wastewater treatment plant used Modified Carrousel Oxidation Ditch process formerly,and achieved B level of the first-order of Discharge Standard of Pollutants from Municipal Wastewater Treatment Plants(GB 18918—2002).Considering the extremely small construction area of the available wastewater treatment plant,the second phase expansion project was based on the modified Unitank process.This paper described the technology and design parameters of the treatment process which provided the reference for the expansion project or new project of the limited landing index.
