Abstract

The invention provides a nanometer graphene purification system for treating medical sewage containing novel coronaviruses. The nanometer graphene purification system comprises a medical sewage collecting and conveying device, at least two stages of sedimentation tanks, a filtering device, at least three stages of graphene sterilization devices, a multiple purification tank, a photocatalytic degradation device, an advanced novel coronavirus purification device and at least three stages of graphene water purification devices. The invention further provides a process for applying the nanometer graphene purification system for treating the medical sewage containing the novel coronaviruses. According to the nanometer graphene purification system and process for treating medical sewage containing the novel coronaviruses in the invention, the novel coronaviruses are deeply killed by utilizing instantaneous high temperature, high pressure and high energy release of micro-nano bubbles; the multi-stage graphene water purification devices and the graphene sterilization devices are cooperatively utilized to deeply kill, block or purify various pathogenic bacteria, parasites and hundreds of pollutants in the medical sewage, so up-to-standard discharge of the medical sewage in infectious disease hospitals can be ensured, and the life safety, the environmental safety and the life health of the masses are further ensured.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a graphene nano-purification system and process for treating medical sewage containing novel coronavirus. Background technique [0002] Medical sewage comes from various sources and its composition is very complex. Generally speaking, medical sewage contains a large number of pathogenic bacteria, viruses and chemical agents, such as various drugs, disinfectants, diagnostic agents, detergents, as well as a large number of pathogenic microorganisms, parasite eggs and various viruses, including roundworms Eggs, hepatitis virus, tuberculosis and Shigella, etc. It has the characteristics of space pollution, acute infection and latent infection. Compared with industrial wastewater and domestic wastewater, medical sewage has the characteristics of small water volume and strong pollution. If it is allowed to discharge, it will seriously pollute water sources and spread dise...
