Open channel ultraviolet sewage disinfection treatment equipment

Open channel ultraviolet sewage disinfection treatment equipment

The open channel ultraviolet sterilizer isBased on the real-time detection of UVC dose, the output intensity of the UV lamp is automatically adjusted according to the changes in flow rate and sewage UVC transmittance to save operating costs. The design of the UV disinfection system and the configuration and design of the UV module comply with the Chinese standard "Urban Water Supply and Drainage UV Disinfection Equipment" (GB/T19837-20), ensuring that the effluent disinfection requirements specified in this contract are met.

During the automatic cleaning process, the system can operate normally and the disinfection effect is not affected in any way. When replacing the lamp tube, quartz sleeve, ballast, and cleaning the quartz sleeve, the system can still continue to be disinfected. The unified UVC sensor is placed in the sewage of the open channel, so that the measured data reflects in real time the changes in the transmittance of the disinfected sewage, the changes in the transmittance of the quartz sleeve, and the intensity changes caused by comprehensive factors such as lamp aging.

Therefore, it is called ultraviolet radiation. Ultraviolet radiation comes from electromagnetic waves emitted by the sun. Ultraviolet radiation is usually classified into four categories based on wavelength. It is a special form of material movement, consisting of unconnected particle streams. Each ultraviolet photon with a wavelength of 253.7nm has an energy of 4.9eV. When ultraviolet radiation is irradiated on microorganisms, energy transfer and accumulation occur, resulting in the inactivation of microorganisms and achieving the purpose of disinfection. When absorbing doses exceeding 3600-65000 uw/c ㎡, it is appropriate. The principle of the external overcurrent ultraviolet sterilizer that exists at the ultraviolet end of the spectrum is that ultraviolet light is a type of light wave that is invisible to the naked eye. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) have strong destructive power, which can cause the loss of survival and reproductive ability, thereby achieving disinfection and sterilization effects. On the one hand, ultraviolet radiation can cause mutations in nucleic acids, hindering their replication, transcription, and protein synthesis. On the other hand, the generation of free radicals can cause photoionization, leading to cell death.
