C-MBR运行条件对膜污染影响的研究

Research on the Effects of C-MBR Operating Conditions on Membrane Fouling

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CMBR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。

The effects of the C- MBR in the aerobic environment and alternating anaerobic / aerobic environment on membrane 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.
