Description
Technical Field

Once the rework and review inevitably leads to a large population of people gathering, the risk of cross-infection will increase greatly. Therefore, the green, safe, dynamic and continuous disinfection is implemented on the places where people gather, such as units, schools, enterprises, super-business and the like, bacteria and viruses in the air are killed, and the problems faced at present can be effectively solved.
At present, a plurality of environmental disinfection (physical and chemical methods) methods are adopted, for example, disinfection modes such as ultraviolet disinfection, 84 disinfection solution, 75% alcohol, peracetic acid and the like can cause harm to human bodies, and most of the methods have the disadvantages of high price, low sterilization efficiency, toxicity to human bodies and unsuitability for dynamic continuous disinfection under the condition that people exist. Therefore, a green, safe, dynamic and continuous disinfection integrated technology system based on a weak-acid hypochlorous acid disinfectant is applied to a novel solution for preventing and controlling the coronavirus pneumonia gathering epidemic situation, the risk of cross infection of crowd gathering places such as schools, factories, writing rooms and business and super-public gathering places can be effectively reduced, green and safe working and learning environments are created, production and learning are orderly recovered, and normal operation of local economy, life and learning is guaranteed.
Weakly acidic hypochlorous acid is an active substance produced by the immune system of the human body. When bacteria, fungi or viruses invade the human body or the epidermis is damaged, the human body autoimmune system can generate hypochlorous acid (an effective bactericidal substance generated by phagemid balls in human blood leukocytes), easily passes through cell walls of prokaryotic bacteria and shells of the viruses, and generates oxidation reaction with proteins, nucleic acids, enzymes and the like in the bacteria (viruses) so as to kill viruses, bacteria, human foreign cells and other germs without damaging normal cells of eukaryotic human and animals.
The weak acidic hypochlorous acid water has the characteristics of strong sterilization efficiency (8 times of sodium hypochlorite), high sterilization speed (80 times of the sodium hypochlorite, can effectively kill various influenza viruses such as avian influenza and the like, norovirus, SARS virus, tubercle bacillus, staphylococcus aureus (including MRSA), multi-drug-resistant pseudomonas aeruginosa, salmonella, Escherichia coli O157: H7 and the like within 0.5 second), wide sterilization spectrum, high safety, no residue, environmental protection, low cost and the like. Weakly acidic hypochlorous acid water is recognized as a food grade antimicrobial agent by the Food and Drug Administration (FDA) in japan. The disinfectant is internationally verified to be the disinfectant which can be used for dynamically and continuously disinfecting air at present.
Based on the high-purity high-stability hypochlorous acid disinfectant (pH is 5.0-6.5), the invention establishes a dynamic continuous disinfection integration technical specification of the weakly acidic hypochlorous acid disinfectant according to green safe dynamic continuous disinfection integration technical solutions formulated for different space sizes and different application scenes of crowd gathering places such as schools, factories, writing rooms, markets, supermarkets, cinemas, bars, restaurants and the like, customizes aerosol generators (wall-mounted, movable, intelligent machine type and corridor type) suitable for different scenes, and can perform good disinfection work in places such as schools, factories, writing rooms, offices, business supermarkets, cinemas, bars, restaurants and the like under the condition of people and nobody.
