有机滤光剂在污水处理厂的分布和去除

Distribution and Removal of Organic UV Filters in Wastewater Treatment Plant

有机滤光剂(Organic UV Filters OUVFs)作为一种新型污染物,由于其在环境水体中微量浓度即可对生物产生雌激素效应,因此引起人们的广泛关注。根据目前国内外已有的研究结果,综述了有机滤光剂在世界各国污水处理厂中浓度水平和分布特征,对比了不同污水处理工艺对有机滤光剂的去除效率。在此基础上,提出了本领域未来研究亟待解决的问题。

Organic UV Filters （ OUVFs）, as a kind of emerging contaminant, has raised worldwide concern due to their potential estrogenic effect on animals even at trace level in the aquatic environment. Based on the current studies, this paper reviewed the concentrations and distribution of main OUVFs in wastewater treatment plants （WWTPs） of different countries in the world. Their removal efficiencies by different treatment processes in WWTPs are also compared. Finally, major issues concerning in this field were proposed in future research.
