Description

Technical Field

[0001] The utility model relates to the field of aquaculture water disinfection, in particular to a photocatalyst seawater aquaculture pipeline type ultraviolet disinfection device. Background Art

[0002] my country is a country with developed marine aquaculture. In recent years, with environmental pollution and eutrophication of sea areas, bacterial, fungal and other diseases have broken out in large numbers, causing huge economic losses to the marine aquaculture industry. In order to kill bacteria and remove pathogens in aquaculture water, the industry widely uses drug disinfection methods, but this method may reduce the efficacy of the drug on rainy days, and may also have adverse effects on aquatic organisms; while ultraviolet disinfection has been increasingly widely used. In the process of aquaculture, the reproduction of algae in the water and the bacteria, viruses, and parasites that cause fish diseases can all die and disintegrate within seconds under strong ultraviolet rays, achieving the purpose of disinfection, thereby reducing the disease rate of fish and increasing aquaculture density and yield. Among them, it is UV-C ultraviolet rays that really have a bactericidal effect, and ultraviolet rays around 254nm are the best. For example, the microwave-specific electrodeless UVC ray lamp can simultaneously emit two wavelengths of ultraviolet rays, namely 253.7nm and 185.0nm. Among them, 253.7nm is mainly used for sterilization and disinfection, and can also photolyze volatile organic compounds (VOCs) with molecular bond energy less than 472. The bond breaking energy of 185.0nm is 647, which is mainly used for photolyzing VOCs. Research has found that the bond breaking energy of UVC+photocatalyst composite technology is stronger and the photocatalytic effect is better.

The disadvantage of this patent is that the sterilization and disinfection effect and the effect of treating volatile organic compounds are weak when using ultraviolet lamps alone, the longitudinal space is large, it is inconvenient for staff to operate, and it is inconvenient to adjust parameters such as water flow when using it.
