    摘要
  • 摘要: 将微生物燃料电池（MFC）与膜生物反应器（MBR）进行耦合，构建了MFC-MBR一体化系统。基于MFC-MBR一体化系统，研究分析了MFC微电场对MBR膜组件周围溶解性微生物代谢产物（SMP）和胞外聚合物（EPS）的分布和迁移的影响。研究结果表明：MFC-MBR一体化系统可提供的最大输出电压为0.78 V。在此电场作用下，MBR的跨膜压差（TMP）达到30 kPa所需时间为14 d，比无外加电场所用时间长6 d。与此同时，扫描电镜显示：在长期运行后，有电场情况下，膜表面覆盖物较无电场少。通过对MBR膜组件周围SMP与EPS进行检测分析，发现在外加电场作用下，SMP与松散胞外聚合物（LB-EPS）会远离膜组件，其浓度会随着与膜组件距离的增加而增大；而紧密胞外聚合物（TB-EPS）不受电场影响，呈均匀分布状态。此外，SMP与LB-EPS在微电场作用下能够进行远离MBR膜表面的定向移动，从而可以有效减缓MBR膜污染，为MBR降低运行成本提供参考。
    Abstract: In this study, the MFC-MBR integrated system was constructed by coupling the microbial fuel cell (MFC) with the membrane bioreactor(MBR). Based on the MFC-MBR integrated system, the effects of MFC micro-electric field on the distribution and migration of soluble microbial products (SMP) and extracellular polymer (EPS) around MBR membrane modules were studied. The results showed that the MFC-MBR integrated system could provide a maximum output voltage of 0.78 V. Under the action of this electric field, the time required for MBR’s transmembrane pressure difference (TMP) to reach 30 kPa was 14 d, which was 6 days longer than that without external power. At the same time, the scanning electron micrograph showed that the film surface covering was less than the electric field in the presence of an electric field after long-term operation. By detecting and analyzing SMP and EPS around the MBR membrane module, it was found that under the action of external electric field, SMP and loose extracellular polymer (LB-EPS) would be far away from the membrane module, and its concentration would increase with the distance from the membrane module. However, TB-EPS was distributed evenly, which relfected that TB-EPS could not be affected by the electric field. The results of this study demonstrated that SMP and LB-EPS could move away from the surface of MBR membrane under the action of micro electric field, which could effectively reduce the pollution of MBR membrane, so as to reduce operating cost for MBR.
