▎ 摘　　要

NOVELTY - Sulfate reducing bacteria electric filtering sterilizing device comprises a filter layer (4) from top to bottom in turn comprises a cathode (5), an anode (7) and a filter core (8). The filter core is graphene nano fiber non-woven fabric, the preparation method of the graphene nano fiber non-woven fabric comprises (1) ultrasonically dispersing the graphene into N, Ndimethyl formamide and dimethyl sulfoxide to obtain graphene dispersion, (2) under the stirring condition, mixing the graphene dispersion with the polyvinylidene fluoride with the number average molecular weight of 80000-120000, obtaining the blend, relative to 1 g graphene, the dosage of the polyvinylidene fluoride is 0.2-0.5 g, and (3) electrospinning the blend to obtain the graphene nano fiber non-woven fabric. USE - Used as sulfate reducing bacteria electric filtering sterilizing device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the sulfate reducing bacteria electric filtering sterilizing device. Filter layer (4) Cathode (5) Anode (7) Filter core (8)
