Research progress of microplastics removal technology in water environment
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 bio-degradation were discussed,focusing on the research progress and effectiveness of new technologies.Final-ly,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 refer-ence for further reducing energy consumption,improving the removal rate of microplastics in water envi-ronment and forming a stable process in the future.
