为解决膜污染问题，开发了一种新型浸没式膜电生物反应器（SMEBR）。为了验证新的设计，在几个阶段完成了实验工作。本文介绍了新开发的SMEBR系统的设计约束条件和标准，并显示了SMEBR系统的性能，以减少膜污染的结果时，间歇直流（DC）（15分钟ON/45分钟OFF），采用圆柱形铁网的两个电极。SMEBR系统的应用提高了膜的过滤性能，通过减少污染率高达16.3%，没有任何反冲洗的膜组件。膜过滤性能的改善与混合液絮凝体的电位从-30.5 mV降低到-15.3 mV和比过滤阻力（SRF）降低到40%相关。
A novel Submerged Membrane Electro-Bioreactor (SMEBR) was developed to treat wastewater and control the problem of membrane fouling. To validate the new design, experimental work was achieved in a few phases. This paper describes the design constraints and criteria of the new developed SMEBR system, and shows the results of the performance of the SMEBR system to reduce membrane fouling when intermittent direct current (DC) (15 min ON/45 min OFF) was applied using cylindrical iron mesh for both electrodes. Application of the SMEBR system enhanced the membrane filterability by reducing the fouling rate up to 16.3% without any backwashing of the membrane module. The improvement in membrane filterability associated with a decrease in potential of the mixed liquor flocs from -30.5 up to -15.3 mV and a decrease in specific resistance to filtration (SRF) up to 40% was observed.
