A^2/O+MBR工艺用于集约化高排放标准半地下式污水厂

坂雪岗水质净化厂二期工程位于深圳市龙岗区华为科技城,设计规模为12×10^4 m^3/d。工程用地紧张,出水水质标准高,常规的生物处理工艺很难稳定达标,故生化处理采用A^2/O+MBR膜工艺。全厂污水处理构筑物区域采用半地下式组合式布置,顶部加盖覆土建设市政公园,综合了传统地面式污水厂及全地下式污水厂的优点,环境优美,运行管理方便。生产运行以来,出水水质稳定优于《地表水环境质量标准》(GB 3838-2002)的Ⅳ类标准(总氮≤10 mg/L)。

Application of A^2/O+MBR Process in Intensive High Discharge Standard Semi-underground Wastewater Treatment Plant

The second-phase project of Banxuegang wastewater treatment plant is located in Huawei Science and Technology City,Longgang District,Shenzhen.The treatment capacity is 12×10^4 m^3/d.Because of the land shortage and the high level of effluent quality,conventional biological treatment process was difficult to meet the requirements.So the combination A^2/O+MBR process was adopted.The area of the wastewater treatment structure of the whole plant adopted a semi-underground combined arrangement,and the top of the wastewater treatment structure was covered with soil to build the municipal park,and the advantages of the traditional ground type wastewater treatment plant and the whole underground wastewater treatment plant were integrated,the environment was beautiful,and the operation management was convenient.Since the production and operation,the effluent quality had been stable and superior to the Ⅳ level standard(TN≤10 mg/L)specified in Environmental Quality Standards for Surface Water(GB 3838-2002).
