非均相催化臭氧化水中药物与个人护理品研究进展

药物和个人护理用品（PPCPs）是一类新兴的有机污染物，与常见的污染物相比，在水环境中浓度很低但化学结构复杂，种类多，性质差异大，具有毒性，常规处理技术很难完全去除。非均相催化臭氧化技术的固相催化剂可回收重复利用，二次污染少，目前此处理技术在PPCPs领域的研究已经非常广泛。文章详细描述了非均相催化臭氧化技术降解PPCPs时常遵循的表面反应机理、自由基反应机理、协同反应机理，进一步阐释了自由基反应机理中的4种途径，简要介绍了催化剂等因素对PPCPs降解的影响，归纳总结了非均相催化臭氧化在PPCPs治理领域的应用进展，提出了现今非均相催化臭氧化技术存在的问题，最后展望了非均相催化臭氧化技术的未来研究方向及应用前景。

Research progress in the oxidation of PPCPs in water by heterogeneous catalytic ozonation

PPCPs are a new type of organic pollutants. Compared with common pollutants, PPCPs have a low concentration in the aquatic environment but have a complex chemical structure, various sorts, enormous properties, and are toxic. The conventional processing technology is difficult to remove PPCPs completely. The solid-phase catalyst of heterogeneous catalytic ozonation technology can be recycled and reused and has less secondary pollution. At present, the research of this treatment technology in the field of PPCPs has been extensive. The article describes the surface reaction mechanism, free radical reaction mechanism, and synergistic reaction mechanism that the heterogeneous catalytic ozonation technology often follows to degrade PPCPs. Meanwhile, it further explained the four ways in the free radical reaction mechanism. The article briefly introduces the effects of catalysts and other factors on the degradation of PPCPs, summarizes the application progress of heterogeneous catalytic ozonation in the treatment of PPCPs, and puts forward the problems existing in the current heterogeneous catalytic ozonation technology. Ultimately, the article prospects the future research direction and application prospects of heterogeneous catalytic ozonation technology.
