Abstract

The present invention belongs to the field of aquaculture technology, and discloses a method for preparing a composite oxygen producer for adsorbing residual antibiotics in aquaculture water. The composite oxygen producer is prepared from the following components by weight: 70-90 parts of an oxygen supply component, 15-25 parts of a traditional Chinese medicine compound, 42-68 parts of an adsorption component, 2 -5 parts of a coating agent, 1-3 parts of a stabilizer and 1.3-1.8 parts of a sustained co-solvent. The oxygen supply component comprises 50-60 parts of sodium peroxide and 20-30 parts of calcium peroxide; the traditional Chinese medicine compound includes celandine, Chinese angelica, Radix Astragali, nephelium lappaceum, receptaculum nelumbinis, fruticose breynia juvenile branchlet and leaf, Hydrangea aspera Don and yucca; the adsorption component comprises 20-30 parts of Chinese medical stone, 6 -10 parts of a polymer material, 9-15 parts of diatomaceous earth and 7-13 parts of silica powder. Through compounding of a plurality of effective components, the obtained product has good oxygenation function and residual antibiotic adsorption function.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a composite oxygenator for absorbing residual antibiotics in aquaculture water and a preparation method thereof. Background technique [0002] With the development of social economy and transportation, a large number of aquatic products are transported from the south to the north, driving the continuous development of the aquaculture industry. A major problem affecting aquaculture is the quality of the water environment. In recent years, antibiotics have been widely used in aquaculture for the prevention and treatment of diseases and the growth promotion of organisms. However, antibiotics are poorly absorbed by the body and have strong water solubility. They often enter the environment in the active form (parent or metabolites) with human and livestock excretion, aquaculture and pharmaceutical wastewater discharge, and eventually remain in water bodies. The resid...
