摘　　要：着重开展了序批式活性污泥法对大蒜加工废水的净化工艺研究。对SBR系统的运行参数(进水时间、反应时间、沉淀时间、排水时间、闲置时间)进行控制,确定在25℃环境下,SBR法处理大蒜加工废水的最佳方案为:进料方式,直接进料;曝气时间,7 h;沉淀时间,1 h;排水时间,1 h,在此条件下经过一段时间培养,SBR系统运行一周期,COD去除率达到94.45%,且系统运行稳定,出水清澈,达到了国家一级排放标准。This article is focus on the research of purification technology for garlic-processed wastewaters by SBR. Operation of SBR system parameters （flow time, reaction time, sedimentation time, drainage time, idle time） of the con- trol to determine the processing of garlic SBR wastewater treatment the best option for the ambient temperature, 25 ~C; feed directly into the materials; aeration time, 7 h; sedimentation time, 1 h; drainage time, 1 h, under the conditions in this training over a period of time, SBR system is running a cycle, COD removal rate reached 94.45 percent, and the system is running stable, clear water to emission standards at the national level.
