摘　　要：针对甘薯淀粉废水COD高,可生化性好的特点,采用ABR法处理该废水。在试验过程中,对ABR启动过程和颗粒污泥特征作了相应的研究;找出了ABR系统中酸解过程的特征及调控恢复措施;对不同水力停留时间下ABR的处理效能进行了研究分析,提出了ABR处理甘薯淀粉废水的最佳工况。结果表明:采用颗粒化较好的厌氧污泥作为反应器的接种污泥,仅用20 d就完成了反应器的启动;反应器最佳HRT为60 h,此时COD的去除率为94.3%;为保证ABR具有较高的去除率,ABR最大容积负荷为12.0 kg/(m3.d);采用同时调节碱度和降低负荷的酸化恢复方式,连续调控20 d后,污泥的产甲烷活性在逐渐恢复。According to the characteristic of the sweet potato wastewater which has high COD and better biodegradability, ABR is used to treat it in this paper. In the experiment process, the start-up of ABR and the feature of granular sludge were studied; the characteristics of hydrolysis-acidification process and controlling approaches in an anaerobic baffled reactor were found out; the treatment effect of ABR in different HRT was analysized and the best operation condition in treating sweet potato starch wastewater was presented. It is shown： the reactor was started up during 20 days by using granular anaerobic sludge as seed sludge; the best HRT of reactor is 60h, and the removal ratio of COD is 94.3 %; in order to ensure ABR having higher removal ratio, the biggest organic loading of ABR is 12.0 kg/（m^3·d）; by taking the measure of adjusting alkaline and decreasing organic load together, methanogenic of sludge is gradually recovering after continuous 20 days.
