摘　　要：水溶液中的有机污染物引起了一系列生态环境问题.现阶段,高级氧化工艺(AOPs)广泛应用于水环境中有机污染物的高效处理,其处理过程的初始溶解氧浓度是影响高级氧化反应的重要参数条件.通过调节溶解氧浓度,以及协同控制pH和其他技术条件可以有效降低AOPs的能耗,提高处理效率和经济效益.本文针对6种代表性AOPs,开展初始溶解氧浓度对氧化体系的影响机制分析,并分别对溶解氧参与的活性物种生成、污染物分解、催化体系影响过程进行了梳理.最后总结了溶解氧在AOPs中的重要性及工程应用中的调控思路,为今后利用参数调控对AOPs降低能耗提升效率的优化研究提供参考.Organic pollutants in aqueous solutions cause a series of ecological and environmental issues.At present,advanced oxidation processes(AOPs)are widely used for efficient wastewater treatment of organic pollutants.Initial dissolved oxygen concentration of the treatment is an important parameter that affects advanced oxidation reactions.By regulating the concentration of dissolved oxygen as well as synergistically controlling pH and other reaction conditions,the energy consumption of AOPs can be reduced,the treatment efficiency and economic feasibility can be further improved.This paper analyzes the impact of initial dissolved oxygen concentration on oxidation systems for six representative AOPs,and summarizes the involvement of dissolved oxygen in the generation of active species,pollutant decomposition,and catalytic processes.The importance of dissolved oxygen in AOPs and its regulatory ideas in engineering applications are discussed,providing references for future optimization research on parameter regulation to reduce AOPs energy consumption and improve efficiency.
