Application of electrospinning nanofiber membranes in the field of wastewater treatment
Nanofiber membranes prepared by electrospinning technology have attracted extensive attention in wastewater treatment due to their characteristics such as small pore size,large specific surface area and interconnected pore structure.In order to broaden the application range of electrospinning nanofiber membranes in waste water treatment,adapting to the increasingly complex water environment,the types of electrospinning nanofiber membranes and the mechanism of wastewater treatment were described based on the research of electrospinning nanofiber membranes in recent years,and the development status of different types of nanofiber membranes in wastewater treatment was reviewed,and the problems of poor mechanical properties and low membrane flux in wastewater treatment were emphasized.It is believed that the mechanical properties of ceramic nanofiber membranes can be enhanced by composite methods,and the membrane flux can be increased by grafting modification and water washing.The research direction will be provided for the preparation of nanofiber membrane with high mechanical strength,excellent anti-fouling performance,recyclable,and resistant to high temperature,strong acid and alkali environment.
