▎ 摘　　要

NOVELTY - Graphene nano purification system for treating medicinal sewage containing coronavirus comprises medicinal sewage collection and transportation devices. At least two-stage sedimentation tanks, and sodium hypochlorite generator is provided in the first-stage sedimentation tank. A filtering device, and at least a three-stage graphene filter screen is provided at least three-stage graphene sterilization device. The graphene sterilization device is filled with superparamagnetic nanoparticles-graphene oxide composite nanomaterials, graphene sterilant or graphene composite and sterilant. The first ultraviolet generating device, graphene chemical oxygen demand degradation agent, and graphene sterilizing agent, multiple purification tank are provided with a connected spray liquid storage tank and an ultrasonic micro-nano bubble generator. The nozzle of the ultrasonic micro-nano bubble generator is placed in multiple purification tank. USE - Used as graphene nano purification system for treating medicinal sewage containing coronavirus. ADVANTAGE - The system: ensures that medicinal sewage from infectious disease hospitals meets the discharge standards, safety of people's lives, environmental safety, life and health. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of graphene nano purification system for treating medicinal sewage containing coronavirus. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene nano purification system for treating medicinal sewage containing coronavirus.
