摘要:

控制水系统(包括废水、再生加工用水和饮用水)中的微生物繁殖对社会健康的生活环境至关重要. 电催化反应产生的反应活性物种(RS)可以使微生物失活, 从而为控制微生物生长提供了有效途径. 本文概述了电催化反应产生RS及其应用于水消毒的最新进展, 重点介绍了RS的选择性生产、微生物与RS的相互作用(包括RS作用机制和微生物对RS的天然反应), 以及催化反应产生的RS用于微生物灭活的实际应用. 本文还展望了基于RS的水电化学消毒的挑战和机遇以及未来可能的研究方向.

Abstract:

Controlling microbial proliferation in water systems, including wastewater, recreational water, and drinking water, is essential to societal health. Microbial inactivation through electrochemically generated reactive species (RS) mediated pathways provides an effective route toward this microbial control. Herein we provide an overview of recent progress toward electrocatalytic generation of RS and their application in water disinfection, with a focus on the selective production of RS, the microorganism interactions with RS (including both RS mechanisms of action and innate microorganism responses to RS), and practical implementation of electrochemically generated RS for microbial inactivation. The article is concluded with a perspective where the challenges and opportunities of RS-based electrochemical disinfection of water are highlighted, along with possible future research directions.
