ABSTRACT
A laboratory scale combination process of anaerobic baffled reactor(ABR) with sequencing batch reactor(SBR) for treatment of real dyeing wastewater was studied.The effects of operational conditions were investigated.The results demonstrated that removal rates of COD,colour and aniline were 32%~95%,89%~99% and 50%~98%,respectively,the effluents of COD were 30.0 ~97.1mg/L,colour were 8 ~40 times dilution ratio,concentration of aniline were 0.20 ~0.95 mg/L,which could meet the National Discharge Criteria(GradeⅠ) under the operational conditions of HRTs of 24~36 h,organic loading rates of 0.43 ~2.46 kg COD/(m~(3)?d),the influent pH values of 6.5~8.0,ambient temperatures of 20℃~35℃ at the ABR stage and DOs of 2 mg/L,reaction times of 3~10h,settle times of 2 h at the SBR stage.
