深床反硝化滤池在某城镇污水处理厂提标改造中的应用及运行分析

Application and Operation Analysis of Deep-bed Denitrification Filter in the Upgrading and Reconstruction of a Municipal Wastewater Treatment Plant

某城市污水处理厂采用改良型卡鲁塞尔氧化沟工艺,因厂区所处地区特殊地形限制、进水水质特点,选用深床反硝化滤池工艺进行提标改造。本文从设计处理工艺,运行情况方面对该污水处理厂提标改造工程进行相关分析。该污水处理厂经提标改造后,工艺稳定运行,出水水质稳定,能达到《城镇污水处理厂污染物排放标准》(GB18918-2002)中的一级A标准。

An urban sewage treatment plant adopts the improved Carrousel oxidation ditch process. Due to the special terrain restrictions and the characteristics of the influent water quality in the area where the plant is located, the deep bed denitrification filter process is selected for upgrading and transformation. In this paper, the relevant analysis of the upgrading and upgrading project of the sewage treatment plant is carried out in terms of the design of the treatment process and the operation situation. After the sewage treatment plant was upgraded and reformed, the process was stable and the effluent quality was stable, and it could meet the Class A standard in the Pollutant Discharge Standards for Urban Sewage Treatment Plants(GB18918-2002).
