This study introduced a novel dual-anode assembled microbial desalination cell to enhance the performance of domestic wastewater treatment. Two parallel units were fabricated with two anodes and one cathode, which is separated by two ion exchange membrane stacks. A hollow fiber membrane module was inserted in the cathode to intercept suspended solids and microbes. Based on preliminary experiments where synthetic wastewater was utilized, anode hydraulic retention time of 10 h and cathode aeration rate of 0.16 m³/h were chosen as the operating conditions. By innovatively connecting four membrane stacks in cascades, which multiplied flow rate without adding extra circulation pumps, the desalination rate of the system was improved 214.8% compared with single membrane stack mode. When modified domestic wastewater was applied, the average removal efficiencies of chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorous reached 96.9%, 99.0%, 98.0% and 98.3%, respectively.

这项研究介绍了一种新型的双阳极组装式微生物脱盐池，以提高生活污水的处理性能。制造了两个具有两个阳极和一个阴极的平行单元，该两个阳极单元被两个离子交换膜堆隔开。将中空纤维膜组件插入阴极以拦截悬浮的固体和微生物。根据利用合成废水的初步实验，阳极水力停留时间为10 h，阴极曝气速率为0.16 m ³/ h被选择为操作条件。通过创新地级联连接四个膜堆，从而在不增加额外循环泵的情况下增加了流速，与单膜堆模式相比，系统的脱盐率提高了214.8％。使用改性生活污水后，化学需氧量，氨氮，总氮和总磷的平均去除率分别达到96.9％，99.0％，98.0％和98.3％。
