Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water body disinfection, specifically a disinfection device for natural water body and factory water product culture, which can be used for degrading organic pollutants in tail water of factory circulating water aquaculture and disinfecting and sterilizing natural water body and factory water product culture water. BACKGROUND

[0002] With the increase of world population year by year, the demand of human for animal food source increases, and factory circulating water culture has become a new industry. The efficient removal of residual bait and water product metabolites in the process of intensive culture has been plagued, so aiming at the disease prevention and control of factory circulating water culture water product and the removal of organic pollutants in culture water, the photocatalytic advanced oxidation technology is applied to solve the problems in the field of factory water product culture, and under the guidance of ecological civilization construction and sustainable development concept, the development of ecological friendly industry technology is good.

[0003] Traditional pipeline type ultraviolet disinfection mostly adopts three ultraviolet lamp tubes, disinfects after sewage enters the pipeline in the way of self-flow, kills escherichia coli in sewage, and achieves the purpose of disinfection. The removal of bacteria, viruses and some persistent organic pollutants in polluted water body is a difficult problem of water product culture water recycling. At present, aiming at this situation, ultraviolet disinfection device is mostly used to purify and disinfect water body, and there is still no good solution for persistent organic pollutants in water body. At the same time, only relying on ultraviolet disinfection, the sterilization efficiency of culture water is not high.

[0004] The ultraviolet sterilizer is an effective method for sterilizing bacterial, eukaryotic and viral contaminants in water, and is a substitute for chemical sterilization technology. As an emerging technology, the ultraviolet-titanium dioxide nanotube sterilization device for industrial aquaculture has many advantages compared to the ultraviolet sterilizers used in the past, such as: the photocatalytic sterilization device composed of ultraviolet lamp tubes and titanium dioxide nanotubes, which will not cause secondary pollution; in addition, the titanium dioxide nanotube has good stability and can be recycled and reused, and has good degradation effect on difficult-to-degrade pollutants in water. Due to the wide band gap of titanium dioxide nanotubes, it mainly absorbs ultraviolet light below 420 nm, which is combined with the ultraviolet lamp tube, so that the pollutants can be degraded and disinfected when the light is turned on. After the titanium dioxide nanotube absorbs photon energy, a series of strong oxidants, such as hydroxyl radicals, oxygen radicals and superoxide radicals, are generated, which can not only degrade pollutants but also have sterilization effect on microorganisms. Combined with ultraviolet irradiation disinfection, it has greatly improved compared to traditional disinfection methods, and provides a new technology for the treatment of tail water in industrial recirculating aquaculture. In recent years, a large amount of exploratory research work has been carried out on ultraviolet disinfection and sterilization, but the research on the improvement of sterilization efficiency using the ultraviolet-titanium dioxide nanotube structure design is still very weak. The design of the new ultraviolet-titanium dioxide nanotube sterilization device for industrial aquaculture will be the most effective technical route for developing high-efficiency and rapid sterilization and pollution degradation modules, and is expected to form a module product that can be applied to the innovation and entrepreneurship industry.
