The application of ultraviolet disinfection technology in wastewater treatment is mainly reflected in the following aspects:

Sterilization effect

Ultraviolet disinfection technology can effectively kill bacteria, viruses, and other pathogens in wastewater. The energy of ultraviolet photons can destroy theDNAstructure, causing them to lose the ability to replicate and reproduce, thus achieving sterilization. The sterilization principle of ultraviolet disinfection is to use the energy of ultraviolet photons to destroy the structures of various viruses, bacteria, and other pathogens in the water body, causing them to lose their ability to replicate and reproduce, thereby achieving sterilization.DNA结构，使各种病毒、细菌以及其它致病体丧失复制繁殖能力，达到灭菌的效果。

Application advantages

Compared with traditional chemical disinfection methods such as chlorine disinfection and ozone disinfection, ultraviolet disinfection technology has multiple advantages. First, ultraviolet disinfection does not require the addition of chemical agents, so it does not produce toxic disinfection by-products. Second, the disinfection process of ultraviolet disinfection is short, usually completed within a few seconds. In addition, ultraviolet disinfection equipment occupies a small area, is easy to operate, has a high degree of automation, and operates safely without bringing toxic, flammable, explosive, and corrosive safety hazards.

Technical characteristics

Ultraviolet disinfection technology is an instantaneous disinfection technology with no sustained sterilization capability. This means that after a period of time through the ultraviolet reactor, there may be a phenomenon of microbial content rebound in the water. This is because theDNArepair mechanism of microorganisms may lead to their revival. Research shows that when the ultraviolet dose exceeds100mJ/cm², photorepair does not occur, and after exposure to ultraviolet light for2hours, some microorganisms will completely lose their photorepair ability.

Environmental protection characteristics

Ultraviolet disinfection technology also has significant advantages in environmental protection. It does not cause secondary pollution to water bodies and is safe and environmentally friendly. Guangmingyuan's ultraviolet wastewater purification and disinfection technology can not only effectively kill bacteria and viruses in wastewater but also effectively eliminate ozone. This technology can be applied in integrated projects for wastewater treatment, water purification for aquaculture fish ponds and ornamental fish ponds, as well as clean sterilization treatment for production water and drinking water.

Development trend

With the continuous promotion of ultraviolet disinfection technology, more and more wastewater treatment plants are beginning to adopt this technology. According to statistics, more than7000wastewater treatment plants at home and abroad have adopted ultraviolet disinfection processes. In the future, ultraviolet disinfection technology is expected to explore more functional effects, making wastewater treatment more convenient and efficient.

Conclusion

In summary, the application of ultraviolet disinfection technology in wastewater treatment has multiple advantages such as efficiency, environmental protection, and safety, making it one of the important technologies in the field of wastewater treatment. With continuous development and improvement of the technology, ultraviolet disinfection will play an even more important role in future wastewater treatment.
