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.
