Abstract

Microplastics (MPs), as a new category of environmental pollutant, have been the hotspot of eco-friendly issues nowadays. Studies based on the aging process, the migration pattern of MPs in runoff rainwater, and the use of bioretention cells to remove MPs from runoff rainwater are beginning to attract widespread attention. This review analyses the migration patterns of MPs in rainwater runoff through their sources, structure and characteristics. The mechanism of removing MPs from runoff stormwater, the purification efficiency of different fillers and their influencing factors, and the accumulation, fate, and aging of MPs in bioretention cells are described. Furthermore, the hazards of MP accumulation on the performance of bioretention cells are summarised. Future directions for removing MPs in bioretention cells are proposed: (1) research on MPs smaller than 100 µm; (2) influence of MPs aging process on bioretention cells; (3) exploration of more effective fillers to enhance their removal efficiency; (4) research on synergistic removal mechanism of MPs and other pollution.

生物滞留池去除雨水径流中的微塑料：综述

微塑料作为一种新型的环境污染物，已成为当今生态友好问题的热点。基于老化过程、径流雨水中MPs迁移模式以及利用生物滞留细胞去除径流雨水中MPs的研究开始受到广泛关注。本文从雨水径流中MPs的来源、结构和特征等方面分析了它们的迁移模式。介绍了径流雨水中MPs的去除机理、不同填料的净化效果及其影响因素，以及MPs在生物滞留池中的积累、归宿和老化。此外，总结了MP积累对生物滞留细胞性能的危害。提出了生物滞留细胞中MPs去除的未来方向：(1)研究小于100µm的MPs；(2) MPs老化过程对生物滞留细胞的影响；(3)探索更有效的填料，提高其去除效率；(4) MPs与其他污染协同去除机理研究。
