To solve the problems of pollutants removal and membrane fouling in membrane bioreactor (MBR) and plate passivation in the process of electrocoagulation (EC), anaerobic baffled membrane bioreactor (ABMBR, 4 cells for anaerobic process and 1 cell for membrane separation) was proposed for anaerobic offsite release of Fe²⁺ in the process of EC. The iron plates were placed in the anaerobic unit and the membrane module was placed outside the electric field. The results showed that the operation time could be extended from 5 to 8 days to 63 days when 3 V intermittent voltage (5 min on and 5 min off) was adapted. As the result of EC, protein and polysaccharide contents of soluble microbial products (SMP) and extracellular polymeric substances (EPS) from sludge and filter cake layer were decreased obviously. The sludge particle size was increased from 400 nm to 80 μm and zeta potential was decreased from −11 mV to −20 mV. The water quality results showed that almost 100 % of ammonia nitrogen (NH₄⁺-N) and 87 % of total phosphorus (TP) were removed under the action of EC without excess sludge discharge. By placing the iron plate in the anaerobic unit, plate passivation was very slow during 195 days of operation, which solved the problem of plate passivation in EC.

为解决电凝（EC）过程中膜生物反应器（MBR）和平板钝化膜的污染物去除和膜污染问题，提出了厌氧折流板式膜生物反应器（ABMBR，厌氧工艺4个池，膜分离1个池）。 Fe ^2+的厌氧异位释放在欧共体的过程中。将铁板放置在厌氧单元中，并将膜组件放置在电场之外。结果表明，采用3 V间歇电压（接通5分钟和断开5分钟）可以将操作时间从5到8天延长到63天。EC的结果是，污泥和滤饼层中的可溶性微生物产物（SMP）和细胞外聚合物（EPS）的蛋白质和多糖含量明显降低。污泥粒径从400 nm增加到80μm，ζ电位从-11 mV降低到-20 mV。水质结果显示，几乎100％的氨氮（NH ₄ ⁺-N）和EC的作用下去除了总磷（TP）的87％，没有过多的污泥排放。通过将铁板放置在厌氧单元中，在195天的运行中，钢板钝化非常缓慢，从而解决了EC中钢板钝化的问题。
