Effective control of the quality of water supply is paramount for public health. This project aims to develop a novel photoelectrocatalysis (PEC) based bactericidal technology capable of instant inactivation and rapid decomposition of waterborne pathogens in recycled water. The PEC processes at the illuminated semiconductor photoanodes with ultraviolet (UV) and visible light activities will be innovatively utilised with the aim of in-situ generation of stable di-halide radical anions, reactive oxygen species and photoholes as effectual bactericides to achieve instant inactivation and rapid decomposition of waterborne pathogens. The success of the project is expected to provide Australian water industry with enabling technology to safeguard recycled water usage.

有效控制供水质量对公众健康至关重要。本项目旨在开发一种基于光电催化（PEC）的新型杀菌技术，能够即时灭活和快速分解再生水中的水生病原体。在具有紫外（UV）和可见光活性的照明半导体光阳极处的PEC过程将被创新地利用，目的是原位产生稳定的二卤自由基阴离子、活性氧和光空穴作为有效的杀菌剂，以实现对水生病原体的即时灭活和快速分解。该项目的成功预计将为澳大利亚水务行业提供保障再生水使用的技术。
