Description

  The present invention relates to a ginger environment improving apparatus using a photocatalyst that can be suitably implemented to suppress the attachment of aquatic organisms to a ginger for aquaculture and the like, and to improve the aquatic environment.

  Aquatic organisms such as algae and barnacles adhere to the aquaculture nets that divide the aquaculture area for fish, crustaceans, shellfish, algae and the like from the surrounding water area over a long period of time. Aquatic organisms adhering to the aquaculture net may impede the flow of water through the aquaculture net, worsen the water quality in the aquaculture area, and lead to the growth of parasites and bacteria, which may damage the good aquaculture environment. is there.

  Therefore, conventionally, a technique has been proposed in which an aquatic organism is prevented from adhering to the aquaculture net by applying a coating containing an adhesion inhibitor such as an organotin compound or a biological repellent component to the aquaculture net. There is a problem that the aquatic environment is polluted by elution or peeling of the paint-containing substance and the aquatic organism adhesion preventing effect lasts only for a short period.

  Further, in this conventional technique, since the paint containing an adhesion inhibitor is expensive and has a low bactericidal effect against the generated bacteria, a technique capable of maintaining the adhesion preventing effect and bactericidal effect over a long period of time is desired. ing.

H ₂ O + h ⁺ → OH + H ⁺

In addition, the following reaction occurs when electrons come into contact with air.
O ₂ + e ⁻ → O ₂ ⁻

The generated OH (hydroxyl radical) and O ₂ ⁻ (active oxygen: superoxide ion) have a stronger oxidizing action than ozone. This active oxygen has a strong bactericidal power and expresses the action of destroying the cell membrane of microorganisms. This function occurs only on the surface of the photocatalyst because the lifetime of the active oxygen is very short, and does not affect the site away from the surface.

These may be used alone, or may be used as a mixture of two or more as long as the photocatalytic function is not impaired, and may be used as an alloy containing these as a main material. In particular, titanium dioxide, which is insoluble in water and used as a cosmetic or toothpaste material, has been confirmed to be safe, has a band gap of 3 eV, and is excited by light having a wavelength of 400 nm or less, that is, sunlight. Thus, the photocatalytic function can be expressed.
