| Abstract: | Authors introduced the process to produce a novel sandwich structure nanofiber super-cleaning material.Purification of water containing microzyme with this novel material was studied,and parameters such as filtration efficiency,the variety of turbidity value of filtrate by means of infiltration and filtration were also determined.The results show that this novel material has high filtration efficiency,e.g.the highest filtration efficiency can reach 99.976%,and the lowest turbidity value is 0.4 NTU.Filtration efficiency is affected by nanofiber density and operation pressure.In the end,the mechanism of filtration was discussed,and the primary mechanisms were mechanical sieving,direct interception and inertial impaction. |
