Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics. It uses specially planned high-power, high-intensity and long-life UVC band ultraviolet light to illuminate flowing water, directly killing various bacteria, viruses, parasites, algae and other pathogens in the water. Ultraviolet sterilization and disinfection is achieved by using ultraviolet rays of appropriate wavelengths to damage the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing the death of growth cells and/or regenerative cells, and thus achieving the effect of sterilization and disinfection.

Ultraviolet sterilizerWorking principle

The sterilization principle of ultraviolet rays is to utilize the energy of ultraviolet light to destroy various viruses, bacteria and other pathogenic organisms in waterDNAUltraviolet rays penetrate the cell membranes and nuclei of microorganisms, breaking the molecular bonds of nucleic acids, causing them to lose their replication ability or activity and die. The ultraviolet sterilization band is between200～300nmBetween them, among which253.7nmIt has the strongest band capability. The ultraviolet sterilizer utilizes the irradiation intensity of ultraviolet lamps, that is, the irradiation intensity emitted by ultraviolet sterilization lamps, which is inversely proportional to the distance of the object being irradiated and disinfected. When the irradiation intensity is constant, the longer the irradiated disinfection object stays and the closer it is to the sterilization lamp tube, the better the sterilization effect; conversely, the shorter it is, the worse it is.

Ultraviolet sterilizerThe advanced nature of disinfection technology

The disinfection effect of ultraviolet disinfection technology on bacteria, viruses and other pathogenic organisms has been recognized worldwide.Ultraviolet disinfectionThis process has advantages that other disinfection techniques cannot match and overcomes the shortcomings of existing traditional disinfection technologies. Many European countries as well as Canada and the United States in North America have respectively revised their environmental legislation in the 1990sWastewater treatmentPost-disinfection, as well asDrinking waterFor disinfection, it is recommended to adoptUltraviolet disinfection technology. Its advanced nature is as follows:

High-efficiency sterilization

Ultraviolet disinfection technology has an unparalleled sterilization efficiency compared to other technologies. Sterilization efficiency Accessible99％－99.9％. table1The sterilization time of ultraviolet disinfection technology for several common bacteria and viruses is generally only required１Within seconds. However, traditional chemical disinfection methods such as chlorine and ozone generally need to achieve the sterilization effect of ultraviolet disinfection20Minutes to１An hour's time.

Highly efficient sterilization with broad-spectrum properties

Among all the current disinfection technologies, ultraviolet disinfection technology has the highest broad-spectrum bactericidal effect. It can kill almost all bacteria and viruses with high efficiency. And it can effectively kill some parasites that are extremely harmful to humans and cannot be effectively killed by chlorine or even ozone. table1Ultraviolet rays can also be seenCThe broad-spectrum sterilization property of water disinfection equipment.

No secondary pollution

Since ultraviolet disinfection technology can be controlled to merely kill bacteria without adding any chemical agents, it will not cause secondary pollution to water bodies and the surrounding environment. It does not change any components in the water. For chlorine disinfection, the organochlorine it generates with organic matter in water has been widely recognized as carcinogenic to the human body. Moreover, the chlorine compounds contained in water can have a counterproductive effect in some cases, causing harm to aquatic organisms and the water environment. The ozone method also has similar problems. A large amount of unpleasant ozone that has not dissolved in water volatilizes into the air, which is harmful to the physical and mental health of nearby workers.

Tips

Ultraviolet disinfection technology, compared with traditional disinfection technology, overcomes the shortcomings of the existing traditional disinfection technology. During the disinfection process, no chemical substances are added, and no harmful substances are produced or left in the water body. The operation is safe and reliable, and the equipment and maintenance are simple. Especially, the investment and maintenance costs are low, and the disinfection effect is excellent.

Ultraviolet sterilizerUltraviolet disinfection lamp tube

The ultraviolet light used for disinfection applications isCThe wavelength range of ultraviolet rays is200-275nrnThe band with the strongest sterilization effect is250-270nrnThe ultraviolet light source used for disinfection must be a sterilizing ultraviolet lamp capable of generating irradiation values that meet national standards.

When preparing ultraviolet disinfection lamps, high-grade quartz glass tubes should be selected to achieve satisfactory ultraviolet irradiation intensity.

Ultraviolet disinfection lamps can be used with materials that have a high coefficient of ultraviolet reflection(Such as polished aluminum plates)The fabricated reflector.

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
