doi:10.16085/j.issn.1000-6613.2025-0265

Abstract

Abstract:

The traditional gas-solid phase high-temperature catalytic oxidation method for the treatment of industrial organic waste gas (VOCs) is greatly hindered by its poor safety, high energy consumption and easy deactivation of catalysts. As an emerging low-temperature VOCs treatment method in recent years, aqueous phase-coupled advanced oxidation technology (AOPs) has attracted wide attention because of its advantages of high safety, mild conditions, low cost and wide applicability. In this paper, the research results of some common advanced oxidation technologies (AOPs) for the treatment of VOCs (such as wet-photocatalytic oxidation, Fenton reaction, persulfate oxidation, and wet-catalytic ozone oxidation) are summarized, the reaction and absorption mechanisms, as well as the influence of reaction conditions in the purification of advanced oxidation technologies, are systematically analyze, and the advantages and disadvantages of various AOPs technologies are analyzed and compared. In this article, we hope that the development of high-efficiency catalysts will help solve these problems.

Key words: volatile organic compounds (VOCs), wet-photocatalytic oxidation, Fenton reaction, persulfate-based oxidation, wet catalytic ozonation oxidation

摘要：

传统气固相高温催化氧化法治理工业挥发性有机废气（VOCs）由于其安全性差、能耗过高、催化剂易失活而受到较大的应用阻碍。水相耦合高级氧化技术（AOPs）作为一种近些年来新兴的低温VOCs治理手段，因其具有安全性高、条件温和、成本低、适用性广等优点而广受关注。本文综述了一些常见高级氧化技术治理VOCs（如湿式-光催化氧化、Fenton反应、过硫酸盐氧化以及湿式-催化臭氧氧化）等方面的研究成果，系统分析了反应和吸收机理，以及反应条件在高级氧化技术净化中的影响，同时分析对比了各类AOPs技术的优缺点，发现该技术在未来工业化应用中的关键问题主要为氧化剂消耗、反应不连续、高效催化剂的研发等，通过本文期待能够对解决这些问题提供帮助。
