Abstract

The advanced oxidation process (AOP) has been extensively studied for treatment of aqueous organic pollutants, and various oxidants have been utilized in AOP. In some cases, the combinations of two oxidants can help to boost the performance of AOP. In this review, the recent works concerning the applications of dual oxidant AOP for the degradation of organic pollutants have been summarized comprehensively. Various dual oxidant systems have been discussed, including O₃/peroxides, O₃/persulfates, peroxides/persulfates, periodate/peroxides, permanganate-based, ferrate-based and others. For each dual oxidant system, the reaction mechanisms and synergy effects as well as the effects of oxidant dosage and pH have been discussed in detail. Catalysts and/or external energy sources helped to enhance the performance of dual oxidant systems, which have also been summarized and discussed systematically. This review further highlights the current achievements and hurdles for dual oxidant AOPs, and also proposes recommendations for future works, such as more attentions on pollutant-specific performances of these systems and applications for real wastewater treatment, further investigations on the performances of new catalysts and cost analysis as well as more focus on the specific properties of dual oxidant systems.

双氧化剂高级氧化工艺降解水体有机污染物：综述

人们对高级氧化工艺（AOP）处理水体有机污染物进行了广泛研究，并在 AOP 中使用了各种氧化剂。在某些情况下，两种氧化剂的组合有助于提高 AOP 的性能。本综述全面总结了近期有关应用双氧化剂 AOP 降解有机污染物的研究成果。文中讨论了各种双氧化剂系统，包括 O3/过氧化物、O3/过硫酸盐、过氧化物/过硫酸盐、高锰酸盐/过氧化物、高锰酸盐基、铁酸盐基等。对于每种双氧化剂系统，都详细讨论了其反应机制和协同效应，以及氧化剂用量和 pH 值的影响。催化剂和/或外部能源有助于提高双氧化剂系统的性能，本综述也对此进行了系统的总结和讨论。本综述进一步强调了双氧化剂 AOPs 目前取得的成就和面临的障碍，并对今后的工作提出了建议，如更加关注这些系统的污染物特定性能和在实际废水处理中的应用，进一步研究新催化剂的性能和成本分析，以及更加关注双氧化剂系统的特定性能。
