摘　　要：近年,药品及个人护理品(PPCPs)的产量和用量不断提升,导致废水中PPCPs的检出浓度和检出频率递增.在环境中多数PPCPs不易分解,可持续存在并保持毒性,对水生态造成慢性影响.大量研究证明,污水二级处理很难实现PPCPs的稳定去除,需要依托臭氧等深度处理工艺.臭氧分子仅对某些特定结构的PPCPs活性高,且氧化速率易受pH值、PPCPs基团电子特性等影响.催化臭氧化技术因可以大量产生具有强氧化性且对PPCPs结构无选择性的·OH而受到关注.笔者综述了PPCPs水污染现状,对比分析了臭氧工艺、催化臭氧化工艺对水中PPCPs的控制效果,总结了非均相催化臭氧化工艺在提高PPCPs矿化效果与工艺适用性等方面的优势,并对非均相催化臭氧化技术的研究方向进行了展望.In recent years,the production and usage of pharmaceutical and personal care products(PPCPs)have been increasing,leading to the increase of detection concentration and frequency of PPCPs in wastewater.In the environment,most PPCPs decompose difficultly,exist sustainably and remain toxic,causing chronic impact on water ecology.A large number of studies have proved that it is difficult to achieve stable removal of PPCPs through secondary sewage treatment,and advanced treatment processes such as ozonation need to be relied on.Ozone molecule only has high activity on PPCPs with specific structures,and the oxidation rate is easily affected by pH value,electron characteristic of PPCPs groups,etc.Catalytic ozonation technology has attracted much attention,because it can produce lots of oOH with strong oxidation and non-selectivity to the structure of PPCPs.In this paper,the current situation of PPCPs water pollution was summarized.The control effects of ozone process and catalytic ozonation process on PPCPs in water were compared and analyzed.The advantages of heterogeneous catalytic ozonation process in improving the mineralization effect and process applicability of PPCPs were summarized.The research prospect of heterogeneous catalytic ozonation technology was also discussed.
