▎ 摘　　要

NOVELTY - Producing graphene filter composite membrane involves filtering carboxylated graphene oxide into membrane support layer by suction filtration or cross-flow filtration to form composite membrane support layer. The ferritic chloride solution is filtered by composite membrane support layer formed to reduce formation of Fenton catalyzing layer catalytic layer containing divalent ferric compound to obtain final composite membrane. USE - Method for producing graphene filter composite membrane (claimed). ADVANTAGE - The method enables to produce graphene filter composite membrane, which enriches refractory pollutant in process of filtering secondary effluent, and improves degradation rate of electrocution layer pollutant.
