Background

Ozone sterilization and disinfection technology: ozone is a strong oxidant, and the sterilization process belongs to biochemical oxidation reaction. Ozone sterilization has the following 3 forms:

1. ozone can oxidize and decompose enzymes required by bacteria for degrading glucose, so that TCA circulation cannot be performed, ATP required by cell life activities cannot be supplied, and bacteria are inactivated and killed;

2. directly acts with bacteria and viruses to destroy organelles, DNA and RNA of the bacteria and destroy the metabolism of the bacteria, so that the bacteria die;

3. penetrate cell membrane tissue, invade into cell, act on outer membrane lipoprotein and inner lipopolysaccharide, make bacterium produce permeability distortion and dissolve and die.

Ozone reacts very rapidly to inactivate bacterial viruses. Its high redox potential determines its wide application in oxidation, decolorization, and odor removal. It has been shown that ozone dissolved in water can kill almost all substances harmful to human body, such as iron, manganese, chromium, sulfate, benzene, phenol, oxide, etc., and can decompose organic substances and kill algae. Compared with the conventional sterilization method, the ozone sterilization and disinfection method has the following advantages:

1. high efficiency. The ozone sterilization takes air as a medium and does not need any other auxiliary materials and additives. Therefore, the coating has good compatibility and thorough sterilization, and simultaneously has strong functions of removing mould and fishy smell;

2. high cleanness. The characteristic of rapid decomposition of ozone into oxygen is the unique advantage of ozone as a disinfectant. Ozone is generated by utilizing oxygen in the air, and no consumable is required to be added. In the disinfection process, redundant oxygen is combined into oxygen molecules after 30 minutes, no residue exists, the problem of secondary pollution caused by a disinfectant method is solved, and secondary cleaning after disinfection is finished is omitted;

3. convenience is provided. Ozone sterilizers are typically installed in clean rooms or air purification systems or sterilization rooms, such as ozone sterilization cabinets, transfer windows, and the like. The opening and the running time of the sterilizer according to the time are set according to the sterilization concentration and the time of debugging and verification, so that the operation and the use are convenient;

4. and (4) economy. Compared with the use and operation of ozone disinfection and sterilization in various pharmaceutical industries and medical health units, the ozone disinfection method has great economic and social benefits compared with other methods. In the rapid development of the industry today, environmental protection is of particular importance, while ozone disinfection avoids secondary pollution from other disinfection methods.

Ultraviolet sterilization and disinfection technology: ultraviolet (or UV) radiation is electromagnetic radiation having a wavelength shorter than visible light but longer than the X-ray. The ultraviolet light has a wavelength in the range of 10 nanometers (nm) to 400 nanometers (nm) and an energy in the range of 3 electron volts (eV) to 124 electron volts (eV). Its name is that the electromagnetic wave frequency in the spectrum is higher than the purple visible to the naked eye, also known as ultraviolet light.

Ultraviolet rays are classified into ultraviolet rays a, ultraviolet rays B, ultraviolet rays C, and the like according to wavelength. The ultraviolet C, abbreviated as UVC, also called deep ultraviolet, generally refers to ultraviolet light wave with wavelength of 100 nm to 280 nm, and its energy is between 12.4eV and 4.43 eV. Scientific researches show that the deep ultraviolet has extremely strong killing effect on microorganisms such as bacteria, viruses and the like.

Ultraviolet sterilization belongs to physical sterilization and has the advantage of broad spectrum. When the proper dosage is applied, all microorganisms including bacteria, viruses, algae, spores and the like can be killed, and the killing effect is very obvious.

1. the irradiation intensity is high, and the light intensity of unit area is more than 1000 times higher than that of mercury lamp. Microorganisms in the irradiation range can be effectively killed in a short time;

2. it is nontoxic, has no residue and no odor. After power failure, the ultraviolet light disappears, and the environment is completely unaffected; the spectral line is concentrated, no noise wave exists, and no ozone is generated;

3. the UVC LED does not contain toxic elements such as mercury and the like, meets the international water guarantee, and is safe and environment-friendly;

4. the working voltage is low, and the safety is good; the volume is small, the control circuit is simple and reliable, and the use is convenient;

5. long service life, generally 10000-20000 hours, and high reliability.
