人工湿地去除水环境微塑料研究进展

Research progress on removal of microplastics in freshwater environment by constructed wetlands

微塑料在水体中的大量存在已威胁到环境和人体的健康,如何去除水环境中的微塑料是目前的研究热点,现有的研究多集中于海水中微塑料的去除,针对淡水中微塑料的相关研究较少。文章综述了微塑料在淡水环境中的污染现状以及污水处理厂不同阶段工艺对微塑料的去除效果,并提出了使用人工湿地去除分散污水中微塑料的想法。从湿地植物、湿地基质、湿地微生物和动物等多个方面对人工湿地去除微塑料进行了分析和展望,为人工湿地去除微塑料提供了理论依据。

The large amount of microplastics in water has threatened the environment and human health.How to remove microplastics in the water environment is a current research hotspot.Existing research mostly focused on the removal of microplastics in seawater,there are few related studies at microplastics in freshwater.This article summarized the pollution status of microplastics in freshwater environments and the removal effects of microplastics in different stages of wastewater treatment plants,proposes the use of constructed wetlands to remove microplastics in dispersed sewage.Wetland plants,wetland substrates,and wetland microorganisms have analyzed and prospected the removal of microplastics in constructed wetlands,providing a theoretical basis for the removal of microplastics in constructed wetlands.
