Description

Technical Field

[0001] The present invention relates to an aquaculture water oxygenation composite solution and its preparation and application, in particular to an aquaculture water oxygenation composite solution containing hydrogen peroxide and its preparation and application, belonging to an innovative technology for aquaculture water oxygenation composite solution containing hydrogen peroxide and its preparation and application. Background Art

[0002] Hydrogen peroxide is a colorless, transparent, highly oxidizing liquid, commonly known as hydrogen peroxide. Due to its special molecular structure, it has very active chemical properties, is extremely easy to decompose into oxygen and water, and has no residual toxicity. It has the functions of bleaching, sterilization, disinfection, and oxygenation, and has mild oxidizing properties. It has been widely used in textiles, cosmetics, detergents, medicine and health, feed industry, aquaculture and other fields.

[0003] In the aquaculture industry, hydrogen peroxide is primarily used for sterilization, disinfection, and oxygenation. It has been included as an oxygenator in the "Chinese Veterinary Pharmacopoeia (2020 Edition)" and a quality standard for "Hydrogen Peroxide Solution (Aquaculture)" has been established in the "Quality Standards for Veterinary Drugs (Chemical Drugs Volume)." This standard defines and requires content determination, usage, dosage, and precautions. In practical applications, hydrogen peroxide is primarily used to address the "floating heads" of farmed animals caused by hypoxia in water, as well as for emergency water oxygenation. It is a non-toxic, harmless, and non-polluting oxygenator. Its bactericidal properties have also been used clinically by the medical community, with benefits such as reducing viruses, killing algae, reducing eutrophication of aquaculture waters, and avoiding or reducing the production of the toxic gas hydrogen sulfide.

[0004] In addition to the advantages mentioned above, hydrogen peroxide solution also has the following problems in actual applications: 1) The veterinary drug quality standard for "hydrogen peroxide solution (for aquaculture)" requires its labeled amount to be 26% to 28%. According to relevant regulations in my country, it is a readily explosive product (hydrogen peroxide solution concentration ≥8.0%), and there are very strict requirements for its production, transportation, storage, sales, and other links; 2) Poor stability: It is extremely easy to decompose under light, heat, redox agents and alkaline conditions, releasing active oxygen, resulting in the loss of its oxygen-enhancing effect during application. Summary of the Invention

[0005] The purpose of the present invention is to consider the above problems and provide a composite solution for oxygenating aquaculture water containing hydrogen peroxide. The present invention can effectively solve the above problems and increase the solubility of oxygen in water by adding surfactants and other means, thereby improving the product's use effect.
