technical field

The invention relates to the technical field of water treatment, in particular to a real-time control system and method for ultraviolet disinfection dose of regenerated water.

Background technique

In order to avoid secondary pollution of reclaimed water caused by pathogenic microorganisms and by-products of chlorine disinfection, most sewage treatment plants currently use ultraviolet rays (produced by ultraviolet lamps) with a wavelength of 253.7nm for disinfection. Ultraviolet radiation to microorganisms causes energy accumulation and transfer. On the one hand, it will cause mutations in microbial nucleic acids, thereby hindering its transcription and replication, and hindering its protein synthesis; on the other hand, the generated free radicals trigger photoionization, resulting in cell death. The effectiveness of UV disinfection depends on the UV dose that the system can irradiate to microorganisms. Factors that affect the generation and transmission of ultraviolet rays, such as the aging coefficient of the ultraviolet lamp, the fouling coefficient of the quartz sleeve, the type and concentration of impurities in the water, directly affect the ultraviolet dose irradiated to the microorganisms, and ultimately affect the ultraviolet disinfection effect of the ultraviolet lamp.
