Paper Title:
Anti-Pollution Behavior Analysis of PVDF UF Membrane Added Different Addition to Filter the Secondary Treated Water of Urban Sewage
  Abstract

In this study, the poly(vinylidene fluoride) (PVDF) Flat ultrafiltration membrane was prepared the gel phase inversion method using different polymer(PEG,PMMA,PVA,PVP) as addition. The flux attenuation and resistance of membrane used for treating the secondary treated water of Urban sewage were studied by ultrafiltration (UF) experiments. The influence of addition to the morphology structure and anti-fouling performance of PVDF UF membrane was analyzed.Result show that using PVA and PVP as addition, the PVDF membranes had through macropore structure in cross-section and the appearance of larger macrovoids in the porous substructure,with the lower contact angle, high efficiency producing water percentage, good washing recovery rate. Meanwhile, adding PEG and PMMA in membrane,which was easy to form irreversible plugging hole pollution owing to distribute some teardrop deadend hole.
