• 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运行性能.研究结果表明,SDRAnMBR对啤酒废水有较好的处理效果,处理过程负荷提高快,有机物去除率高,系统耐冲击负荷的能力强,而且运行非常稳定.正常运行期间,进水COD在2900～5200mg·L^-1,容积负荷为4.97～12.48kg·m^-3·d^-1(以COD计)时,COD的平均去除率为95.15%.膜截留和三相旋转流的共同作用,加强了在高污泥浓度(MLSS)和高负荷条件下运行时的混合和传质,从而强化了SDRAnMBR在高MLSS和高容积负荷下运行的稳定性和出水水质.

• Abstract：The operation performance of a submerged double-shaft rotary anaerobic membrane bioreactor(SDRAnMBR) for treatment of synthetic brewery wastewater was investigated. The results showed that the SDRAnMBR could effectively treat synthetic brewery wastewater,and the system not only ran steadily but rapidly enhanced organic loading,had strong impact resistance and a high rate of organic substrate removal. During normal operation,when influent COD was in the range 2900～5200 mg·L^-1 and the volume loading rate was in the range 4.97～12.48 kg·m^-3·d^-1(calculated based on COD),an average of 95.15% COD was removed. Because of the combination of membrane interception and the three-state rotating fluid,the effluent quality and operation stability were strengthened significantly at high mixed liquor suspended solids(MLSS) and high volume loading rate.
