Abstract

As a novel and efficient technology of water treatment

membrane bioreactor has been successfully used in waste water treatment. In the field of membrane separation engineering

polyvinylidene fluoride (PVDF) becomes the hot point of study. This paper presents the methods of preparation of PVDF membrane used in MBR briefly. The modification of PVDF membrane with PEBAX

PVDF-g-POEM

PVDF-g-PEGMA

TPU

SiO

is introduced. The development prospect of PVDF membrane is as well forecasted. In a certain extent

the PVDF membranes could enhance hydrophilia and anti-pollution capacity effectively

prolong the using life and cut down running cost after modification. Besides

the effluent water quality is better. PVDF membrane may have broader applications in case of increaseing mechanical strength.
