水中微塑料污染及去除技术的研究进展

Research Progress of Microplastics Pollution in Water and Removal Technology

微塑料以各种途径进入水中,微塑料具有停留时间长、稳定性高、破碎可能性高的特点,对生态和人类的健康存在的潜在风险引起了人们的关注。文章介绍了水中微塑料的污染现状及危害,阐述了水中微塑料去除技术。目前,已经开发了多种用于微塑料去除的技术,包括混凝、吸附、过滤、磁分离和生物降解等。根据去除效率、环境影响和经济可行性对这些技术进行探讨。综述了近年来国内外对水中微塑料主要去除技术的研究概况,阐述了微塑料去除技术相关研究进展,对比分析了其优势和劣势,并对水环境中微塑料去除技术未来的研究方向进行了展望,为今后高效去除水中微塑料提供了研究基础。

Microplastics(MPs)enter the water body in various ways with the characteristics of long retention time,high stability and high possibility of breakage.It poses potential risks to the ecology and human health,and has attracted people′s attention.This paper introduces the pollution status and harm of MPs in water,and states the removal technology of MPs in water.At present,variety of removal technologies have been developed for MPs removal,including coagulation,adsorption,filtration,magnetic separation and biodegradation,etc.These technologies are discussed according to removal efficiency,environmental impact and economic feasibility.This paper reviews the research on the main removal technologies of MPs in water at home and abroad in recent years,states the progress of related research on MPs removal technology,in order to understand its advantages and disadvantages.Additionally,this paper looks forward to the future research direction of MPs removal technology in water environment,which provides a research basis for how to effectively remove MPs in water in future.
