摘　　要：以去除蛋白后的滞头废水为基质对厌氧折流板(ABR)反应器处理效果进行研究,分析了ABR反应器的工艺特征和运行稳定性,同时对反应器各格室颗粒污泥特性进行分析。结果表明:ABR反应器在(35±1)℃,HRT为32 h,进水COD浓度由500 mg/L逐步提高到5 000 mg/L,运行稳定后,COD去除率保持在90%以上;保持进水COD浓度不变,HRT分别为32、24、18和12 h下运行,随着HRT的减少和容积负荷的增加,COD的去除率逐渐降低,但均保持在80%以上,ABR对水力冲击负荷具有良好的适应性;电镜下各格室污泥均凹凸不平,有孔隙和孔洞,越往后,孔洞与孔隙越密实,反应器具有良好的相分离特点,保证了反应器的处理效果。A bench-scaled anaerobic baffled reactor（ABR） was set up to conduct experimental treatment of wastewater from a frigon factory.Wastewater samples after being pretreated to remove a part of protein was pumped to the ABR,undergoing anaerobic digestion,and reaching the stable operation for certain hours.The study focused on granular sludge in the compartments of the ABR regarding its characteristics by means of scanning electro-microscopy.Results showed that a removal of more than 90% could be maintained under the normal condition with the influent concentration of COD 5000 mg/L,and ABR was able to tolerate hydraulic shock loading.Besides,the reactor showed the characteristics of good phase separation that ensure its efficiency of treatment.
