摘　　要：针对制革综合废水有机污染浓度高的特点,采用厌氧折流板反应器(ABR)-曝气生物滤池(BAF)新工艺处理,试验研究了ABR和BAF的启动以及水力停留时间(HRT)、有机负荷及其他因素对处理效果的影响。试验结果表明:ABR在HRT为12 h、水温25～37℃,BAF在HRT为2.5 h、DO≥2.0 mg/L的条件下,组合工艺对制革综合废水的COD平均去除率达88%,出水COD、SS、色度、总铬等指标达DB 44/26—2001《广东省地方标准水污染物排放限值》一级标准。Aiming at high strength organics content in tannery wastewater,the ABR-BAF process was used to treat the wastewater.It was experimentally studied the influences of the biological device startup,hydraulic retention time（HRT）,organic load and other factors on treatment effect.The wastewater was treated by the combined process under optimal conditions： HRT of 12 h to ABR and temperatures range from 25 ℃ to 37 ℃,HRT of 2.5 h to BAF and DO≥2.0 mg /L.The results showed that the average removal percentage of COD was more than 88%,and effluent quality could reach the first-order of＂Water Pollutants Emission Limit in Guangdong＂（DB 44 /26—2001）.
