设计了一种面向应用的可堆叠式水平MFC (SHMFC)，并证明了它具有污水处理和能量回收的双重功能。该系统由多个可堆叠的250 L模块组成，是目前最大的单个MFC模块。生活污水以水平平流方式进入SHMFC。在稳定工作期间，在外部电阻为1 X的情况下，每个模块的最大电流为0.435 +/- 0.010 a，最大功率密度为116 mW。出水COD为70 +/- 17 mg L-1，去除率为79 +/- 7%；出水TN为13 +/- 3 mg L-1，去除率为71 +/- 8%。从250 L的SHMFC模块与28 mL的4cm立方MFC模块的对比来看，内阻分布发生了变化，接触电阻在放大过程中成为可分配的甚至是限制因素。(C) 2014 Elsevier Ltd.版权所有。
An application-oriented stackable horizontal MFC (SHMFC) was designed and proved to be capable for sewage treatment and simultaneously energy recovery. The system consisted of multiple stackable 250 L modules, which is the largest single MFC module by far. Domestic wastewater was fed into SHMFC in horizontal advection. During the stable operation period, a maximum current 0.435 +/- 0.010 A in each module was observed under the external resistance of 1 X and the maximum power density was 116 mW. The effluent COD was 70 +/- 17 mg L-1 with a removal rate of 79 +/- 7% and the effluent TN was 13 +/- 3 mg L-1 with a removal rate of 71 +/- 8%. From the comparison between SHMFC module (250 L) and 4-cm cubic MFC (28 mL), the internal resistance distribution changes and the contact resistance becomes assignable and even limiting factor in the enlargement.
