银定庄污水处理厂提标改造工程设计及运行效果

Design and Operation Effect of Yindingzhuang WWTP Upgrading and Reconstruction Project

随着国家对污水处理厂的出水排放标准要求越来越高,国内大部分污水处理厂均面临提标改造的问题。银定庄污水处理厂总设计规模为24×10^4m^3/d,一期为8×10^4m^3/d,二期为16×10^4m^3/d,现状出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918-2002)的二级标准。此次提标改造工程将原有A/O生化池改造为~A2/O+A/O工艺。同时新增了乙酸钠加药间、除磷加药间、纤维转盘滤池及活性砂滤池、鼓风机房等建(构)筑物,以保证出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)的一级A标准。

With the increasing national requirements on discharge standards of wastewater treatment plants (WWTP),most WWTPs are faced with the issue of upgrading and reconstruction. The total design scale of Yindingzhuang WWTP is 24 × 10~4 m^3/d,including the first phase of 8 × 10~4 m^3/d and the second phase of 16 × 10~4 m^3/d. The original effluent quality was subject to the secondary level but has been improved to the first level A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Thus the original A/O process was upgraded and reconstructed into A^2/O + A/O process. At the same time,new structures such as sodium acetate dosing room,phosphorus removal dosing room,fiber rotary filter tank,active sand filter tank and blower room have been added.
