Photoelectric sterilization and algae remover is an excellent product for controlling algae base in landscape water bodies.

In fact, the lake water body is also an organic water ecosystem. It must control nutrients, primary productivity, plant allelopathy, food chain and other aspects to accelerate the material flow rate of the ecosystem, improve the system's biodiversity and self-purification ability, and follow the trend. It is the ultimate solution for landscape water bodies. In waterscape management, it is a very important technical measure to control the algae base so that it cannot eventually evolve into algae blooms. The photoelectric sterilization algae remover is an excellent product for killing bacteria and algae and controlling the algae base in landscape water bodies.
The photocatalytic sterilization and algae remover uses solid-supported photocatalytic materials, which has excellent sterilization, algae removal, and odor removal effects. Its sterilization capacity is more than twice that of simple ultraviolet disinfection (same power), especially this equipment It also has strong algae removal ability and certain micro-flocculation effect, and cooperates with the ecological filter bed to reduce the filter bed area to one-seventh of the original area. The equipment can also remove refractory organic matter in the water body that cannot be removed by biochemical treatment. Make fish grow healthier This product is small in size, light in weight, easy to install, simple to operate and has low energy consumption.
Scope of application:
Large lakes
Ornamental fish breeding pools
Disinfection and sterilization mechanism:
In the ornamental fish breeding system, due to the high breeding density, it is easy to cause the spread of diseases. The effective operation of the disinfection device is crucial to the cultivation of ornamental fish in landscape water bodies. Ultraviolet rays are invisible light with a wavelength range of . It has a bactericidal effect at wavelengths of .
Ultraviolet disinfection mainly kills microorganisms by irradiating them (bacteria, viruses, spores and other pathogens) and destroying the function of nucleic acids or). It can also cause damage to other structures of microorganisms, thereby achieving the purpose of disinfection.
The main problem with ultraviolet disinfection is that it does not have residual disinfection capacity. After the treated water leaves the reactor, some microorganisms killed by ultraviolet light will be resurrected and regenerated under the photoresurrection mechanism. However, large doses of ultraviolet radiation can prevent bacterial light The effect of resurrected UV disinfection is greatly affected by the ultraviolet transmittance (UV) of the quartz tube. In the management of the UV disinfection system, special attention should be paid to the cleaning of the outer wall of the quartz sleeve to ensure a high ultraviolet transmittance.
The main component of photocatalysis () is nano-titanium dioxide (). It is non-toxic and harmless, and has been widely used in various fields such as food, medicine, cosmetics and so on. The photocatalyst will produce a photocatalytic reaction (redox reaction) similar to photosynthesis under the irradiation of light, producing free hydroxyl radicals and reactive oxygen species with extremely strong oxidizing ability. These products can kill pathogenic microorganisms and decompose organic pollutants. After absorbing light energy, the electrons in the valence band (b) will be excited to the conduction band (b), forming negatively charged highly active electrons, and at the same time generating positively charged holes + in the valence band. Under the action of the electric field, electrons and holes are separated and migrate to different positions on the particle surface. Thermodynamic theory shows that + distributed on the surface can oxidize molecules adsorbed on the surface into free radicals, and the oxidizing ability of free radicals is the strongest among the oxidants present in water, so it can efficiently and quickly kill various bacteria, Viruses and pathogenic microorganisms that are resistant to general disinfectants can also be completely decomposed and will eventually be degraded into harmless substances such as chlorine and chlorine. In addition, the oxidation potential of many organic compounds is more negative than the valence band potential and can be directly oxidized by +. Those with high surface activity have strong reducing ability and can reduce and remove metal ions in water.
The mechanism of photocatalytic killing of microorganisms mainly includes direct reaction and indirect reaction. The direct reaction is that photogenerated electrons and holes directly react with the cell wall, cell membrane or the components of the cell, so the indirect reaction for killing bacteria is the photogenerated electrons or photogenerated holes. The holes react with water or dissolved oxygen in the water to form reactive oxygen species with strong oxidizing ability such as, Its respiratory system and electronic transmission system thereby effectively kill germs.
