摘　　要：以生活杂用水为回用目标,研究了AO-MBR一体化污水处理系统对生活污水的处理情况。试验表明,HRT为8 h、SRT为50 d、回流比为120%时,冬季阶段,系统出水的COD浓度低于30 mg/L,BOD5浓度低于10 mg/L,氨氮浓度低于5.0 mg/L,色度低于30度,浊度低于0.3 NTU;夏季阶段,系统出水的COD在2.1～20.5 mg/L之间,BOD5在1.5～7.4 mg/L之间,氨氮在0.04～2.57 mg/L之间,色度在10～30度之间,浊度在0.12～0.27 NTU之间,出水水质达到生活杂用水水质标准。A wastewater treatment system combined with AO and MBR was studied in dealing with the domestic sewage.The results showed that,when the HRT was 8 h,SRT was 50 d,reflux ratio was 120%,in winter,the outlets concentration of COD,BOD5,NH3-N,chromaticity and turbidity were lower than 30 mg/L,10 mg/L,5.0 mg/L,30 degree,0.3 NTU,while in summer,the effluent concentration of COD,BOD5,NH3-N,chromaticity and turbidity were 2.1~20.5 mg/L,1.5~7.4 mg/L,0.04~2.57 mg/L,10~30 degree,0.12~0.27 NTU.The effluent water quality reached the miscellaneous domestic water quality standard.
