摘    要:当污泥浓度维持在19~20g/L时,一体式平板膜-生物反应器运行112d,通量稳定在25.2~25.7L/(m2.h),运行过程除正常曝气以保持对膜进行水力冲刷外没有进行任何物理和化学清洗。试验考察不同DO浓度对同步硝化反硝化效果的影响,结果表明,反应器内有较好的硝化反硝化效应,当温度在18~12℃变动时,膜生物反应器的硝化反硝化效果基本不受温度的影响。

关 键 词:一体式膜-生物反应器  平板膜  同步硝化反硝化  污水处理

Abstract:The integrated flat plate MBR was operated at membrane flux 25.2~25.7 L/(m~2·h) for 112 days with MLSS concentration 19~20 g/L.During the operation,MBR was not cleaned physically or chemically except normal aeration which was used to scour membrane surface.The effect of DO concentration on simultaneous nitrification and denitrification (SND) in the MBR was investigated.Test results indicated that there was a good SND effect in MBR; and SND effect was not affected by temperature variations in range of 18~12 ℃.
Keywords:integrated membrane bioreactor  flat plate membrane  simultaneous nitrification & denitrification and wastewater treatment
