摘　　要：序批式活性污泥法是一种间歇式活性污泥法。该方法将污水处理的曝气及沉淀等单元操作工序在一个反应池中按时间顺序反复进行。在总结SBR工艺特征和运行控制基础上,为了探讨低温条件(10—15℃)下SBR工艺设计和运行参数的影响因素,实现低温条件下SBR法处理生活污水工艺条件的优选,在一个有效容积为5.5m3的反应器内进行了试验研究。实验结果表明,当工况时间设置为厌氧3h、曝气8h、缺氧1.5h、闲置1.5h时,达到最佳运行工况。Sequencing Batch Reactor was a kind of intermittent batch reactor, which the unit operation processes such as aeration and sedimentation were ran in the same pool in chronological repeatedly. Based on summarizing the technology characteristics and operagonal control of SBR, this subject was to research the process design and operating parametens of SBR under the low- temperature conditions, and achieved the optimization of sewage treatment technology.Based on researching the reactor whose effective volume was 5.5m^3 ,it indicated that it could achieve the best operating condiitons under the conditions of anaerobic 3h, aeration 8h, hypoxia 1. 5h, respectly.
