▎ 摘　　要

NOVELTY - Hollow fiber composite biofilm has a tubular shape, an outer hollow fiber membrane layer, an outer layer of graphene oxide, a biofilm layer, an inner layer of graphene oxide, and a hollow layer from the outside to the inside. The inner layer of the fibrous film is serrated from the cross-section of the biofilm layer. The outer layer of the plasticizer is disposed between the outer layer of the graphene oxide and the biofilm layer, where the biofilm layer and the inner layer of the graphene oxide are disposed between the outer layer and the biofilm layer. USE - Hollow fiber composite biofilm. ADVANTAGE - The hollow fiber composite biofilm improves filtration effect on algae, bacteria, and microorganisms. DETAILED DESCRIPTION - Hollow fiber composite biofilm has a tubular shape, an outer hollow fiber membrane layer, an outer layer of graphene oxide, a biofilm layer, an inner layer of graphene oxide, and a hollow layer from the outside to the inside. The inner layer of the fibrous film is serrated from the cross-section of the biofilm layer. The outer layer of the plasticizer is disposed between the outer layer of the graphene oxide and the biofilm layer, where the biofilm layer and the inner layer of the graphene oxide are disposed between the outer layer and the biofilm layer.
