摘要
为满足《城镇污水处理厂污染物排放标准》(GB18918—2002)一级A标准的要求,无锡惠山污水处理厂三期工程在强化生物处理后采用占地面积小、动力消耗低、脱氮效果稳定的深床反硝化滤池作为把关工艺对其进行深度处理,通过在线碳源投加装置适应水质的变化。详述了该工程的设计参数、工艺流程及其设计特点。
To meet the class I -A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）, the third-stage project of Wuxi Huishan WWTP adopted deep-bed denitrification filter after the enhanced biological treatment because the deep-bed denitrification filter has advantages of small occupied area, low energy consumption and stable nitrogen removal efficiency. Moreover, the online carbon source addition device was used to fit the change in wastewater quality. The design parameters of the project, the treatment process flow and its design characteristics are expounded.
