Embodiment 1

[0016] Using nano photocatalyst 301 special sol produced by Changchun Lilong Nano New Technology Promotion Center, soak the ultrafine multi-strand chemical fiber cloth for 20 minutes, then dry it at room temperature, and the photocatalyst material is fixed on the cloth. A certain amount of chemical fiber cloth impregnated with nano-photocatalyst 301 special sol is evenly immersed in a certain amount of water in the pool, and the photocatalyst on the cloth is activated under direct sunlight or ultraviolet light for a certain period of time, causing the water to produce (H + ) and (OH - ) and other active species. When the active species reaches a certain amount, nano active water will be produced.

Embodiment 2

[0018] In actual production, the (H + ) and (OH - ) and other active species are relatively difficult, and the following method can be used: use 1.2kg of tap water to immerse the cloth coated with photocatalyst material 301 special sol in water, and its light receiving area is 12057cm 2 , with 8w ultraviolet quartz lamp tube, the ultraviolet irradiation intensity is 0.66mw / cm 2 , The water produced by the photocatalysis time is more than 10 minutes is nano-active water. This is a production unit. For industrial batch production of nano-active water, it is enough to increase the unit according to the above ratio.

Abstract

The present invention discloses one kind of nanometer active water and its production process. The nanometer active water is produced through soaking solid medium in sol of photcatalyst material, soaking the solid medium in water, and irradiating water with sun light or ultraviolet ray for some time to make water generate hydrogen ion, hydroxyl ion and other active seeds and become the nanometer active water under the action of the holes in the photcatalyst material. The present invention also describes the definition and standard of the nanometer active water. The nanometer active water may be used widely in various fields to replace partial pesticide, food preservative, etc. for producing green food, beverage, medicine, etc.

Description

technical field [0001] The invention belongs to the technical field of water treatment. Background technique [0002] Nano active water is produced with ordinary tap water. Under the irradiation of sunlight or ultraviolet light through nano-photocatalytic materials, valence electrons will be excited to the conduction band, thereby generating photogenerated electrons (e - ) and photogenerated holes (h + ), under the action of the electric field force, the two are separated and migrate to the surface of the nano-photocatalyst material particle respectively, and the water is formed by the effect of the hole on the surface of the photocatalyst material (H + ) and (OH - ) and other active species. Under the action of a certain photocatalysis time, the water will contain a certain amount of active species, such water is nano-active water. It stores light energy in water. The active water has the functions of sterilizing, killing viruses, antisepsis, and curing diseases, and ...
