摘　　要：研究了新型浸没式双轴旋转厌氧膜生物反应器(SDRAnMBR)处理模拟啤酒废水的启动特性。讨论了水力停留时间、容积负荷与COD去除率的关系;pH、挥发酸(VFA)和碱度对启动的影响。仅用26d就完成了反应器的启动和污泥的驯化。结果表明,SDRAnMBR系统的耐冲击负荷能力强;COD去除率高于常规厌氧生物反应器,稳定在92%以上;反应器运行稳定,未发生酸化现象;且出水VFA和出水碱度可以在较大的范围变动而不会发生酸化现象。The start-up characteristic of a new type submerged double-shaft rotary anaerobic membrane bioreactor treating synthetic brewery wastewater was studied. The influence of HRT, COD loading rate, pH, volatile fatty acid, alkalinity and COD removal efficiencies on start-up process was investi-gated. The reactor was started up during 26 days. Experiment results showed that the SDRAnMBR had strong ability of endurance impact loading, high COD removal which stabilizes at above 92%, higher than conventional anaerobic bioreactor. The reactor can run steadily and the acidification phenomenon has not happened. Furthermore, effluent VFA and alkalinity can change in the larger scope and acidification phenomenon will not happen.
