C－MBR 运行条件对膜污染影响的研究

摘要

The effects of the C-MBR in the aerobic environment and alternating anaerobic/aerobic environment on mem-brane fouling are studied in the experiment .Results show that ,the EPS ,SMP and MLVSS of the C -MBR in the alternating anaerobic/aerobic environment are all lower than that in the aerobic environment .The C -MBR that runs in alternating anaerobic/aerobic environment can not only alleviate the membrane fouling obviously ,but also reduce energy consumption per unit volume of sewage treatment by reducing the aeration .%实验对C－MBR在好氧环境和厌氧／好氧交替环境下的膜污染进行了研究。实验结果表明C－MBR在厌氧／好氧交替环境下运行时，反应器内EPS、SMP和MLVSS均比好氧环境运行下低。C－MBR在厌氧／好氧交替环境下运行不仅可以明显缓解膜污染，而且曝气量减少可以降低处理单位污水的能耗。
