Research and Application Progress of Vacuum Ultraviolet(185 nm) in Water Treatment

真空紫外线(VUV,185 nm)和基于VUV的高级氧化技术(VUV-AOPs)作为新型水处理技术,近年来在水处理领域得到了越来越多的研究和应用。首先介绍了VUV光源、VUV剂量测定以及纯水体系中涉及的主要反应;其次,介绍了应用VUV和VUV-AOPs降解水中污染物、对水消毒及其处理成本评估;最后,对其未来发展方向进行了展望。

Vacuum ultraviolet （VUV, 185 nm） and VUV-based advanced oxidation processes（VUV-AOPs） , as emerging water treatment technologies, have attracted increasing attention of research-ers in water treatment field. The present paper first summarizes the VUV light sources, VUV fluenee de-termination, and main reactions involved in pure water system. Then, the applications of VUV and VUV-AOPs to pollutant removal and water disinfection are introduced together with their treatment cost estima-tions. Finally, future development directions of the VUV and VUV-AOPs in water treatment are pro-posed.
