摘要
水中新污染物的去除是环境工程领域的热点与难点。 研究表明,基于过氧乙酸(PAA)活化的高级氧化技术可诱生具有强氧化性的活性物种来降解水中的新污染物。 目前,常用的 PAA活化策略包括直接活化(紫外光、超声、热、电活化)、均相活化(金属离子与无机阴离子活化)与非均相活化(金属催化剂与碳催化剂活化)三类。 本文系统综述了各类 PAA 活化策略的反应原理与典型新污染物的降解性能,阐述了不同 PAA 活化策略中活性物种的类型与来源;分析了不同 PAA 活化策略的主要影响因素,比较了不同活化策略的优势与适用性。 最后,基于 PAA 活化高级氧化技术发展与应用面临的挑战,展望了 PAA 活化技术未来的发展方向。

Abstract
The removal of emerging contaminants (ECs) from water has been a hotspot and a challengein the field of environmental engineering. Advanced oxidation processes ( AOPs) based on peraceticacid (PAA) activation can generate active species with strong oxidative capability to attack ECs in wa⁃ter. Currently, reported strategies for PAA activation include direct activation, homogeneous activation,and heterogeneous activation. This paper provides a systematic review of the reaction mechanisms of va⁃rious PAA activation strategies, the degradation performance of typical ECs, and the types and sourcesof active species in different PAA activation strategies. The main influencing factors of different PAAactivation strategies have been analyzed, and a comparison has been made regarding the advantages andapplicability of different activation strategies. Finally, considering the challenges faced in the develop⁃ment and application of PAA activation AOPs, future research directions are proposed.
