Abstract：
The evolution of emerging contaminants (ECs) has caused greater requirements and challenges to the current biological wastewater treatment technology. As one of the most promising biological treatment technologies, the aerobic granular sludge (AGS) process also faces the challenge of ECs. This study summarizes the recent progress and characteristics of several representative ECs (persistent organic pollutants, endocrine disrupting chemicals, antibiotics, and microplastics) in AGS systems that have garnered widespread attention. Additionally, the biodegradation and adsorption mechanisms of ECs were discussed, and the interactions between various ECs and AGS was elucidated. The importance of extracellular polymeric substances for the stabilization of AGS and the removal of ECs is also discussed. Knowledge gaps and future research directions that may enable the practical application of AGS are highlighted. Overall, AGS processes show great application potential and this review provides guidance for the future implementation of AGS technology as well as elucidating the mechanism of its interaction with ECs.
摘要：
新兴污染物（EC）的演变对当前的生物废水处理技术提出了更高的要求和挑战。作为最有前途的生物处理技术之一,好氧颗粒污泥(AGS)工艺也面临着ECs的挑战。本研究总结了几种具有代表性的ECs(持久性有机污染物，内分泌干扰物,抗生素,和微塑料）在AGS系统中引起了广泛关注。此外,讨论了ECs的生物降解和吸附机理，阐明了各种EC和AGS之间的相互作用。还讨论了细胞外聚合物对稳定AGS和去除EC的重要性。强调了可能实现AGS实际应用的知识差距和未来研究方向。总的来说,AGS流程显示出巨大的应用潜力，本综述为AGS技术的未来实施以及阐明其与EC相互作用的机制提供了指导。
