摘　　要：采用折流式厌氧反应器(ABR)处理难降解印染废水,对其启动过程进行了试验研究。接种污泥由某工业园区污水处理厂厌氧水解池内的厌氧絮状污泥和某造纸废水处理内循环厌氧反应器的厌氧颗粒污泥按质量比4:5混合接种,采用实际印染废水与葡萄糖按一定比例混合配水作为启动进水,控制COD的平均容积负荷为0.97 kg.m-.3d-1,逐步减少葡萄糖并直至完全不加。反应器经过约60 d的连续运行,稳定运行期COD平均去除率39.5%,色度平均去除率63.4%,印染废水BOD5/COD由0.20提高到0.39,可生化性明显改善。A start-up study on the treatment of persistent printing and dyeing wastewater was carried out using an anaerobic baffled reactor（ABR）.The seed sludge was composed of anaerobic activated sludge from the hydrolytic tank of a wastewater treatment plant in a town and anaerobic granular sludge from the IC reactor of a papermaking wastewater treatment project with the ratio of 5：4.The start-up influent included complex printing and dyeing wastewater and glucose,which were mixed according to a certain proportion.Keep the average volume rate loading（VRL） constant as 0.97 kg·m-3·d-1,and the amount of glucose was gradually reduced until zero.After continuous operation about 60 d,average COD removal rate and color removal rate were 39.5%,and 63.4%,respectively.BOD5 /COD of printing and dyeing wastewater was raised from 0.2 to 0.39,indicating the improvement of its biodegradability.
