Abstract

Activated carbon (AC) is a cornerstone in water treatment technologies and is renowned for its robust ability to eliminate a wide range of contaminants. However, the adsorption capability of AC diminishes over time and eventually reaches saturation. Given environmental and economic considerations, the regeneration of spent AC emerges as a preferable option. Advanced oxidation processes (AOPs) have been considered a promising approach for spent AC regeneration due to their high efficiency in degrading organic pollutants. This review provides an overview of established AOPs technologies for AC regeneration, elucidating their regeneration mechanisms and key influencing factors. A critical comparison of physicochemical transformations in postregeneration AC and the regeneration efficiency through various AOPs technologies is presented. Moreover, the review addresses some common overlooks in AC regeneration experimental designs and explores the scalability of AOPs regeneration technologies. Finally, future research directions were suggested to improve the AOPs-based regeneration technologies.

活性炭再生的高级氧化工艺：从基础到应用

活性炭（AC）是水处理技术的基石，以其消除各种污染物的强大能力而闻名。然而，随着时间的推移，活性炭的吸附能力会逐渐减弱，最终达到饱和状态。考虑到环境和经济因素，废 AC 的再生成为一种可取的选择。高级氧化工艺（AOPs）在降解有机污染物方面具有很高的效率，因此被认为是一种很有前景的废 AC 再生方法。本综述概述了用于 AC 再生的成熟 AOPs 技术，阐明了其再生机制和关键影响因素。本综述对再生后 AC 的物理化学转化以及各种 AOPs 技术的再生效率进行了重要比较。此外，综述还讨论了交流电再生实验设计中的一些常见缺陷，并探讨了 AOPs 再生技术的可扩展性。最后，提出了改进基于 AOPs 的再生技术的未来研究方向。
