摘要
芜湖市某污水厂现状规模10×10^(4)m^(3)/d,出水执行国家一级A排放标准。进行升级改造,出水水质达地表准Ⅳ类水标准。通过方案对比研究,对现有生物反应池好氧段进行重新划分,部分划分为缺/好可调区,部分投加好氧悬浮填料,强化硝化反硝化过程,确保出水水质稳定达标,可为污水处理厂地表准Ⅳ类水提标改造提供借鉴。
The current scale of a wastewater treatment plant(WWTP)in Wuhu City is 10×10^(4)m^(3)/d.Its effluent is in compliance with the first level A discharge standard of China.WWTP is upgraded and reconstructed.Its effluent quality meets the surface quasi-class Ⅳ water standard.By comparing and studying the schemes,the aerobic zone of the biological reaction tank is re-divided.The part of the tank is divided into the adjustable area of anaerobic/aerobic zone,and the part of the tank is used for adding the aerobic suspended filler in order to enhance the nitrification and denitrification process,which ensures the effluent quality up to standard stably,and can provide a reference for the upgrading and reconstruction of WWTP surface quasi-class Ⅳ water.
