高级氧化技术降解水中药物及个人护理品的研究进展

Research advances in the degradation of pharmaceuticals and personal care products in aquatic environment by advanced oxidation processes

目前,药物和个人护理品(PPCPs)在城市污水厂出水和水环境中频繁检出,已经引起了越来越多的关注。常规的污水处理工艺、饮用水处理工艺对PPCPs的降解都极其有限。高级氧化技术能高效降解PPCPs,且降解后其生化性大幅提高。全面阐述了O3/H2O2、TiO2光催化氧化、UV/H2O2、Fenton法及光助Fenton法这些高级氧化技术降解PPCPs的研究进展,并根据现有高级氧化技术降解PPCPs研究中的一些不足之处,提出了PPCPs高级氧化处理领域今后研究的主要方向和需解决的问题。

Recently,more and more attention has been paid to pharmaceuticals and personal care products（PPCPs）,since they have been frequently found in the detection of effluent from municipal sewage treatment plants and aquatic environment.The conventional treatment processes of wastewater or drinking water cannot do much about the degradation of PPCPs.Advanced oxidation processes（AOPs） are highly effective on PPCPs degradation,and the biodegradability of the effluent is significantly improved after the degradation.The related research of advanced oxidation processes on the degradation of PPCPs are expounded entirely,including O3/H2O2,titanium dioxide（TiO2） photocatalytic oxidation,UV/H2O2,Fenton and photo-Fenton oxidation.In view of the disadvantages of these AOPs researches in PPCPs degradation,the research direction and problems that need to be solved for the PPCPs degradation by AOPs in the future are proposed.
