Abstract:

In recent years, the application of activated sodium percarbonate (SPC) and peroxymonocarbonate (PMC) in water treatment has received extensive attention from scholars. By investigating a large number of domestic and foreign documents, this article systematically summarizes the current application of activated SPC system and activated PMC system in water treatment, and sorts out the common activators in SPC system, such as iron-based materials, biochar and metal composite systems, etc. , and the common transition metal ions and metal complex activators of PMC system. The main influencing factors and reaction mechanism of activating SPC and activating PMC system to degrade pollutants are explained. The influencing factors include the initial pH of the solution, the oxidant, the activator, the concentration of pollutants, and the coexisting ions. The addition of activators in the SPC and PMC systems will promote the generation of HO· and play a role in the degradation of pollutants. Finally, suggestions are made for the development trend of related research in the future. It is possible to further explore the repair performance of activated SPC and PMC systems on water, as well as their stability and safety in actual water treatment, and clarify the mechanism for free radicals generated in the system to remove pollutants in water.

Key words: percarbonate, peroxymonocarbonate(PMC), activator, wastewater treatment, advanced oxidation, hydrogen peroxide (H2O2)

摘要:

近年来,活化过碳酸盐(SPC)和过氧碳酸氢盐(PMC)高级氧化体系在水处理中的应用受到了学者们的广泛关注。本文通过调研大量国内外文献,系统总结了目前活化SPC体系及活化PMC体系在水处理中的应用,梳理了在SPC体系中常见的活化剂,如铁基材料、生物炭及金属复合体系等,在PMC体系常见的过渡金属离子以及金属复合物活化剂等,对比分析了活化SPC及活化PMC体系降解污染物的影响因素及其反应机理,影响因素包括溶液初始pH、氧化剂、活化剂、污染物浓度以及共存离子等,在SPC和PMC体系中添加活化剂均会促进HO·的生成,并对污染物的降解发挥作用,最后对未来相关研究的发展趋势提出了建议,可进一步探究活化SPC和PMC体系对水体的修复性能以及利用其进行实际水处理时的稳定性和安全性,厘清体系中产生的自由基对水体中污染物的去除机制。
