Abstract:SBR process was used in studying the phenomenon of aerobic denitrification during the denlmfication of wastewater.The test procedure was:anoxic mixing for 3 h,aerating for 8 h,anoxic mixing for l.5 h,settling for 1 h and draining.When the ρ(NH4+-N)and ρ(CODCr)of the influent water were 107 mg/L and 700 mg/L respectively,the removal rate of NH4+-N in the aerobic section reached 53.3% and the TN removal in the said section accounted for 71.23% of that of the whole cycle,which indicated that the aerobic denitrification played the main role in the denitrification in the whole cycle.

不一定是最佳条件。推荐西南交大博士论文《屠宰加工废水生物脱氮工艺过程及动力学研究》(付永胜)
