Abstract

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.
- productivity expansion,
- upgrading and reconstruction,
- AAO-MBR process,
- non-stop construction
