Description

Technical Field

[0002] Sewage refers to water that contains pollutants after use, mainly from domestic sewage, industrial wastewater and agricultural drainage. Sewage contains various organic matter, inorganic matter, suspended matter, bacteria and viruses. If it is discharged directly into the environment without treatment, it will cause serious pollution to the water body and ecological environment. Disinfection is one of the essential steps in the sewage treatment process. Ultraviolet disinfection and chlorine disinfection are the most commonly used disinfection methods in the disinfection process. In order to solve the problem that ultraviolet disinfection cannot provide residual disinfection capacity, after the treated water leaves the reactor, some microorganisms killed by ultraviolet rays will repair damaged DNA molecules under the photoresurrection mechanism to regenerate bacteria. Ultraviolet disinfection alone does not have continuous disinfection ability, and chlorine disinfection has poor disinfection effect on spores, etc. At the same time, high dosage of chlorine will increase the generation of disinfection by-products. Therefore, improvements are needed. Utility Model Content
