Chlorine disinfection inevitably generates carcinogenic by-products. Alternative non-chlorine-based techniques in centralized treatment plants cannot produce residual antimicrobial power in water disinfection systems. Here, we propose locally enhanced electric field treatment (LEEFT) for chemical-free water disinfection in pipes. A tubular LEEFT device with coaxial electrodes is rationally developed for easy adaption to current water distribution systems as a segment of the pipelines. The center electrode is modified with perpendicularly grown nanowires, so that the electric field strength near the tips of the nanowires is significantly enhanced for pathogen inactivation. We have demonstrated >6-log inactivation of bacteria with 1 V, a small voltage that can be generated in situ by flowing water.

新兴的研究者系列：采用纳米线修饰电极的局部增强电场处理（LEEFT），用于管道中的水消毒

氯消毒不可避免地会产生致癌性副产物。集中处理厂中的其他非基于氯的技术无法在水消毒系统中产生残留的抗菌力。在这里，我们建议对管道中的无化学物质水进行局部增强电场处理（LEEFT）。合理开发了带有同轴电极的管状LEEFT设备，以易于适应作为管道的一部分的当前水分配系统。中心电极用垂直生长的纳米线修饰，因此纳米线尖端附近的电场强度显着增强，可用于病原体灭活。我们已经证明了1V细菌的> 6-log失活，这是一个很小的电压，可以通过流水原位产生。
