摘要: 成都市某污水处理厂在不新增土地、不停产情况下，采用AAO-MBR主体工艺，通过改造生化处理单元和深度处理单元等，将污水处理规模从10万m³/d提升至15万m³/d，同时将出水水质中的主要指标COD、BOD₅、NH₃-N和TP由GB 18918-2002《城镇污水处理厂污染物排放标准》一级标准A标准提升至GB 3838-2002《地表水环境质量标准》Ⅳ类标准。

Abstract: AAO-MBR process was adopted in a wastewater treatment plant of Chengdu for the capacity expansion and ungrading. The treatment capacity was upgraded from 100000 m³/d to 150000 m³/d by transforming the biochemical treatment unit and advanced treatment unit without adding new land occupation or production stop. Meanwhile, the main indexes of COD, BOD₅, ammonia nitrogen and total phosphorus in the effluent quality was upgraded to meet the requirement of class IV standard in Environmental Quality Standards for Surface Water (GB 3838-2002), from the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002) Class I.
