Abstract:To studytheapplication effectof inverted Anaerobic-Anoxic-Oxic (AAO)process inunderground municipal sewage treatmentplants,takingasewage treatmentplantinJinan,Shandongprovinceasanexample,theactualperforance and optimized design of the inverted AAO process in the removal of Chemical Oxygen Demand (COD),NH -N,Total Nitrogen (TN),and Total Phosphorus (TP)were analyzed indetail.Research hasshown thatthe invertedAAO process hassignificantadvantages inoptimizingdenitrificationandnitrogenremoval,enhancinganaerobicphosphorusrelease, and efcient aerobic phosphorus uptake.The efluent qualityofthe treatment plantis stableand meets the standard, with some indicators better than the Class I V waterstandard in the“Environmental Quality Standards for SurfaceWater” (GB 3838—2O02),whichverifies thereliabilityand promotion value of the inverted AAO processin improving sewage treatment efficiency and stability.
