Nitrogen and Phosphorus Removal of AmOn Integrative Process:Effect and Design Optimization

Abstract:

An integrated nitrogen and phosphorus removal process(AmOn) was developed based on the traditional theory of wastewater nutrients treatment process.A reactor was operated in a pilot-scale study,by using activated sludge model No.2D(ASM2D)to optimize the process.The results show that the treatment efficiency of CODCr,NH3N,TN and TP of domestic wastewater achieved by AmOn are up to 74.40%,93.15%,73.35% and 33.20% respectively.Mathematics model established based on experimental results simulated the effect of reactor well,and the combination of anaerobic/anoxic/aerobic districts smartly could accomplish design optimization.AmOn process occupies less space,and effluent could reach the second national discharge standard.After optimization the effluent quality can be further improved.
