【摘要】：药品和个人护理用品(pharmaceuticals and personal care products,PPCPs)作为新兴的环境污染物逐渐引起了广泛关注,不仅因为其在地表水中难以检测,更因为即便是极低的含量,也会对与其接触的生物产生生理毒性效应.尽管其在环境中的质量浓度仅有μg/L到ng/L,但对水生生物表现出一定的内分泌干扰,对人类健康有潜在的威胁.因此,低成本去除废水中的PPCPs吸引了研究人员的关注.关于PPCPs在污水中的迁移转化已有大量研究,从传统的污水处理到新型的处理过程,从实验室到实地监测.本文综述了多种光致氧化工艺去除PPCPs的优缺点,包括光催化、直接光解、臭氧化、光电催化等.阐明PPCPs的迁移转化及其影响并限制其对生态环境的污染,是保护未来生态环境和人类健康的关键.
[Abstract]:Pharmaceutical products and personal care products (PPCPs), as emerging environmental pollutants, have become a growing concern, not only because they are difficult to detect in surface water, but also because of their extremely low levels. They also have physiological toxic effects on the organisms they come into contact with. Although their mass concentrations in the environment are only 渭 g / L to ng / L, they have some endocrine disruptions to aquatic organisms and have a potential threat to human health. The removal of PPCPs from wastewater at low cost has attracted the attention of researchers. A great deal of research has been done on the migration and transformation of PPCPs in wastewater, from the traditional wastewater treatment to the new treatment process. From laboratory to field monitoring, this paper reviews the advantages and disadvantages of various photooxidation processes for removing PPCPs, including photocatalysis, direct photolysis, ozonation, photocatalysis, etc. It is the key to protect the future ecological environment and human health.
