邻苯二甲酸酯在水环境中的分布及去除技术研究进展

Research Advances in Distribution and Removal Technology of Phthalic Acid Esters in Water Environment

邻苯二甲酸酯(PAEs)是我国地表水和污水处理厂中高频检出的一类微量难降解有机污染物,在水环境中的浓度一般是μg/L级别,但对人体具有内分泌干扰毒性和生殖毒性,是关系到二级生化出水深度处理和再生水安全利用的重要污染物。文中系统综述了PAEs的理化性质、环境风险和在水环境中的分布特征,总结了国内外污水处理厂中PAEs的处理技术,并分析了各种处理技术的效果、存在的不足及发展方向。在此基础上,对PAEs去除技术的未来发展方向进行了展望,旨在为再生水安全利用和水环境生态风险控制技术的发展提供指导。

Phthalic acid esters(PAEs)are a type of refractory organic pollutants detected at high frequency in surface water and wastewater treatment plants(WWTPs)at home.Their concentrations in water environment are generally at ug/L level,while they have endocrine-disrupting toxicity and reproductive toxicity to human body,thus act as an important type of pollutants related to the advanced treatment of secondary biochemical effluent and the safe reuse of reclaimed water.This paper systematically reviews physical and chemical properties,environmental risks and distribution characteristics of PAEs in water environment,summarizes the treatment technologies of PAEs in WWTPs at home,and analyzes the effects,shortcomings and development directions of various processing technologies.On this basis,the future trends of PAEs removal technologies are prospected.This paper aims to provide guidance for the development of safe utilization of reclaimed water and ecological risk control of water environment.
