The use of advanced oxidation processes (AOPs) to remove pollutants in various water treatment applications has been the subject of study for around 30 years. Most of the available processes (Fenton reagent, O3 under basic conditions, O3/H2O2, O3/UV, O3/solid catalyst, H2O2/M(n+), H2O2/UV, photo-assisted Fenton, H2O2/solid catalyst, H2O2/NaClO, TiO2/UV etc.) have been investigated in depth and a considerable body of knowledge has been built up about the reactivity of many pollutants. Various industrial applications have been developed, including ones for ground remediation (TCE, PCE), the removal of pesticides from drinking water, the removal of formaldehyde and phenol from industrial waste water and a reduction in COD from industrial waste water. The development of such AOP applications has been stimulated by increasingly stringent regulations, the pollution of water resources through agricultural and industrial activities and the requirement that industry meet effluent discharge standards. Nevertheless, it is difficult to obtain an accurate picture of the use of AOPs and its exact position in the range of water treatment processes has not been determined to date. The purpose of this overview is to discuss those processes and provide an indication of future trends.
在各种水处理应用中，采用高级氧化工艺（AOPs）去除污染物已成为约30年的研究课题。大多数现有工艺（芬顿试剂、碱性条件下的臭氧、臭氧/过氧化氢、臭氧/紫外线、臭氧/固体催化剂、过氧化氢/M(n+)、过氧化氢/紫外线、光助芬顿、过氧化氢/固体催化剂、过氧化氢/次氯酸钠、二氧化钛/紫外线等）都已得到深入研究，并且已经积累了大量关于许多污染物反应活性的知识。已开发出各种工业应用，包括土壤修复（三氯乙烯、全氯乙烯）、去除饮用水中的农药、去除工业废水中的甲醛和苯酚以及降低工业废水中的化学需氧量。日益严格的法规、农业和工业活动对水资源的污染以及工业满足废水排放标准的要求，推动了此类AOP应用的发展。然而，目前难以准确了解AOPs的使用情况，其在水处理工艺范围内的确切地位至今尚未确定。本综述的目的是讨论这些工艺，并指出未来的发展趋势。
