An electrochemical reactor employing activated carbon fibers (ACF) was constructed for the disinfection of bacteria in drinking water. The application of an alternating potential of 1.0 V and -0.8 V versus a saturated calomel electrode, for disinfecting and desorbing bacteria, enabled reactor operation for 840 h. Drinking water was passed through the reactor in stop/flow mode: 300 ml/min flow for 12 h and no flow for 12 h, alternately. The bacterial cell density in treated water was always been less than 20 cells/ml. It was also found that the formation of biofilm on the ACF reactor caused an increase in current, enabling the self-detection of microbial fouling.
构建了一种采用活性炭纤维（ACF）的电化学反应器用于饮用水中细菌的消毒。相对于饱和甘汞电极施加1.0 V和 -0.8 V的交变电位来消毒和解吸细菌，使得反应器能够运行840小时。饮用水以停止/流动模式通过反应器：交替以300 ml/分钟的流量流动12小时，然后停止流动12小时。处理后水中的细菌细胞密度始终低于20个/毫升。还发现ACF反应器上生物膜的形成导致电流增加，从而能够对微生物污染进行自我检测。
