摘要

摘要: 纳米二氧化铈（CeO₂）以其独特的理化性质被广泛应用于工业生产和日常生活中，因而会不可避免地被释放进入污水处理厂内并与微生物发生相互作用，进而对其净污活性和污水处理系统的运行稳定性产生影响。从污水处理系统内纳米CeO₂的归趋和迁移转化过程，对功能微生物表面性能、功能活性和群落组成的影响等方面系统综述了纳米CeO₂在污水处理系统内的环境行为与毒性效应；阐明了纳米CeO₂对污水处理系统运行效果的影响并总结了能够缓解纳米CeO₂影响污水处理系统运行稳定性的措施，旨在为控制和预防纳米CeO₂在污水处理系统中引起的环境风险提供理论基础和科学依据。

Abstract: With the rapid development of nanotechnology, nanoceria (nano-CeO₂) with novel physicochemical properties are widely applied in industrial and consumer products. It is inevitable for the increasing quantities of nano-CeO₂ being released into the wastewater treatment plants (WWTPs), which would further impose adverse effect on wastewater purification and stable operation of WWTPs. In this review, the fates and transformations of nano-CeO₂, the effects of nano-CeO₂ on the surface properties, functional activities and community composition of microbes were systemically discussed to illustrate the environmental behaviors and toxicity effects of nano-CeO₂ on WWTPs. Furthermore, the influences of nano-CeO₂ on WWTPs and strategies to attenuate the negative effects of nano-CeO₂ on WWTPs were summarized. This paper was aimed to provide theorical and scientific basis for controlling and preventing the environmental risks of nano-CeO₂ in WWTPs.
