摘要: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具有
固相催化剂可回收重复利用、二次污染少的优点,已在 PPCPs 领域得到广泛关注。总结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;简要介绍了不同因素对 PPCPs 降解的影响,总结了非均相催化臭氧化在 PPCPs 治理领域的应用进展;
提出了非均相催化臭氧化技术存在的问题,展望了其未来研究方向及应用前景。

Abstract: Pharmaceuticals and personal care products (PPCPs) are a new type of organic pollutants.
Compared with common pollutants, PPCPs have a low concentration in the aquatic environment but a
complex chemical structure, various types, large difference in properties, and toxicity. Conventional
treatment techniques are difficult to completely remove them. Heterogeneous catalytic ozonation
technology has been widely concerned in the PPCPs field because of its advantages of recycling and reuse
of solid phase catalyst and less secondary pollution. The surface reaction mechanism, free radical reaction
mechanism and synergistic reaction mechanism of heterogeneous catalytic ozonation technology for
degradation of PPCPs are summarized. The four ways in the free radical reaction mechanism are further
explained. The effects of different factors on the degradation of PPCPs are briefly introduced, and the
application progress of heterogeneous catalytic ozonation in the treatment of PPCPs is reviewed. The
problems existing in heterogeneous catalytic ozonation technology pointed out and its future research
direction and application prospect are forecasted.
