A^2/O-MBR组合工艺运行优化与氮磷深度控制的分析

Operation optimization of A^2/O-MBR combined process and depth control of nitrogen and phosphorus removal

为了遏制水环境不断恶化的趋势,应加强对氮、磷超标的治理工作,促进水生态环境平衡发展。本文采用A^2/O-MBR作为主体工艺,后续辅以化学除磷和以深床滤池为反硝化单元的组合工艺,确保最终出水满足天津市《城镇污水处理厂污染物排放标准》(DB12/599-2015)A标准排放要求。

In order to curb the continuous deterioration of the water environment,we must strengthen the control of excessive nitrogen and phosphorus and promote the balanced development of the aquatic environment.This article uses A^2/O-MBR as the main process,followed by a combined process of chemical phosphorus removal and a deep bed filter as a denitrification unit to ensure that the final effluent meets the Tianjin Municipal Wastewater Treatment Plant Pollutant Discharge Standard(DB12/599-2015) A standard emission requirements.
