摘要:

近年来，活化过碳酸盐高级氧化技术由于低成本、安全、稳定等特点，越来越多的学者将其应用于处理水中的各类有机污染物，有望成为一种新兴的环境友好型水处理技术。通过查阅近十年大量国内外文献，在总结了活化过碳酸盐降解有机污染物的机理的基础上，系统综述了均相活化、非均相活化、物理活化、联合活化等不同过碳酸盐的活化方法与活化反应机制，并针对活化过碳酸盐高级氧化技术应用于降解废水中的各类有机污染物、膜污染控制、污泥脱水及污泥厌氧消化等方面的研究现状展开阐述。最后指出目前水处理研究领域活化过碳酸盐高级氧化技术存在的问题，并对未来的重点研究方向进行了展望，以期为该技术在水污染治理中的进一步推广和应用提供参考。

Abstract:

In recent years, the advanced oxidation process of activated percarbonate has been applied to treat various organic pollutants in water by many scholars due to its low cost, safety and stability, which is expected to become a new environment-friendly water treatment technology. By reviewing a large number of domestic and foreign literatures in the past decade, the mechanism of activating percarbonate for oxidative degradation of organic pollutants was summarized, and the different activation methods and reaction mechanisms of percarbonate such as homogeneous activation, heterogeneous activation, physical activation, combined activation were systematically reviewed. The research status of activated percarbonate advanced oxidation process applied to the degradation of various organic pollutants in wastewater, membrane pollution control, sludge dewatering and sludge anaerobic digestion were also described. Finally, the problems of activated percarbonate advanced oxidation process in the field of water treatment research were pointed out, and the key research directions in the future were prospected, with a view to providing a reference for the further popularization and application of this technology in water pollution control.
