▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide modified film capable of accelerating water treatment comprises (i) dissolving the oxidized graphene into de-ionized water to obtain the graphene oxide solution, (ii) obtaining a reduced graphene oxide product form the graphene oxide solution in step (i), and centrifuging, washing, and vacuum drying to obtain a reduced graphene oxide, (iii) dissolving reduced graphene oxide in dimethylacetamide solution to obtain graphene oxide-dimethylacetamide dispersion, and (iv) obtaining the polyvinylidene fluoride/reduced graphene oxide composite membrane by phase inversion preparation method. USE - The method is useful for preparing reduced graphene oxide modified film capable of accelerating water treatment process. ADVANTAGE - The method: can improves biological film anti-pollution performance of part of the nitrogen, phosphorus and other organic pollution substance absorbed to the membrane surface, and accelerates contaminant removal process of membrane bioreactor system.
