水环境中微塑料去除技术研究进展

Research progress of microplastics removal technology in water environment

首先概述了水环境中微塑料的来源、分布及对人体的危害,原生微塑料和次生微塑料可通过地表径流和污水厂出水进入引用水,从而被人类摄入体内,引发多种毒性作用。随后讨论了膜技术、磁分离、电絮凝、光催化降解与生物降解等新技术的处理原理、去除效果与优缺点,重点关注各项新技术研究进展及其有效性。最后据此提出了实验研究及后续处置方面的展望。归纳了水环境中微塑料去除技术研究进展,以期为未来进一步降低能耗、提高水环境中微塑料的去除率,形成稳定工艺提供参考。

This paper first summarizes the source,distribution and harm to human body of microplastics in the water environment.Primary and secondary micro plastics can enter the drinking water through surface runoff and sewage plant effluent,which can be absorbed by human body and cause a variety of toxic effects.Then,the treatment principle,removal effect,advantages and disadvantages of new technologies such as membrane technology,magnetic separation,electrocoagulation,photocatalytic degradation and biodegradation were discussed,focusing on the research progress and effectiveness of new technologies.Finally,the prospect of experimental research and subsequent disposal is put forward.This paper summarizes the research progress of microplastics removal technology in water environment,in order to provide reference for further reducing energy consumption,improving the removal rate of microplastics in water environment and forming a stable process in the future.
