▎ 摘　　要

NOVELTY - A graphene bio-enzyme comprises an active carbon filter layer and a rough filter screen, where the filter core preparation material further comprises a high efficiency particulate filter net, graphene bio-enzyme solution and adhesive, and the graphene bio-enzyme solution comprises graphene powder biological enzyme and diluted buffer solution. USE - Graphene bio-enzyme for removing virus filter core. ADVANTAGE - The graphene bio-enzyme can be prepared with better antibacterial effect and better effect of killing virus purifying filter core. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene bio-enzyme.
