摘　　要：阐述了微塑料常规污水处理系统中微塑料的去除效果与机理研究进展,包括分析了多个国内污水处理厂不同污水处理工艺对微塑料去除效果的影响。在一级处理中“格栅+沉砂池+初沉池”的组合去除效果最佳,二级为MBR工艺,三级为过滤工艺。同时对未来污水处理系统的发展趋势进行了展望,如去除工艺的组合研究,对微塑料去除新技术的研发,生物去除、高级氧化等。This paper describes the research progress of microplastics removal effect and mechanism in conventional microplastics wastewater treatment system,including the analysis of the effects of different wastewater treatment processes on the removal effect of microplastics in several domestic wastewater treatment plants.In the first stage treatment,the combination of“grille+sedimentation tank+initial sedimentation tank”has the best removal effect.The second stage is MBR process,and the third stage is filtration process.At the same time,the future development trend of sewage treatment system is prospected,such as the combination of removal process research,research and development of new micro-plastic removal technology,biological removal,advanced oxidation and so on.
