Comparison of the A²/O and Reversed A²/O Process at Low Organic Loading in Wuhan Shahu WWTP and the Optimized Program

Abstract:

Based on the actual operation of Wuhan Shanhu WWTP, and combined with the actual feature of A2/O process and reversed A2/O process, this text analyzed the practical effect of which the CODcr is only 48% of the design value and the sludge load is 15.2% of the design value, and the reason for the aged-sludge and the high effluent value of NH³-N, proposed corresponding adjustment and optimized operation program. The result of optimal operation mode shows that the biodegradable organic matter content in activated sludge increases from 49% to 78%. The effluent quality is superior to the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The electric consumption saves 0.09kWh/m.
