A kind of multifunctional base modifier and preparation method thereof

Abstract

The invention discloses a multifunctional base modifier and a preparation method thereof. The multifunctional bottom modifier includes: peanut shell powder, peanut antimicrobial peptide, peanut water-soluble dietary fiber, tea polysaccharide, diatomaceous earth, xanthan gum, cerium ammonium nitrate, zeolite powder, Bacillus pumilus, Bacillus subtilis, swamp red Pseudomonas, Lactobacillus plantarum, Saccharomyces cerevisiae. Preparation method: cerium ammonium nitrate and xanthan gum are catalyzed by microwaves to make xanthan gum polysaccharide-cerium complex; mix it with diatomite, Bacillus pumilus, Bacillus subtilis, Rhodopseudomonas palustris, Lactobacillus plantarum , beer yeast to make microcapsule preparation; peanut shell powder, peanut antibacterial peptide, peanut water-soluble dietary fiber, tea polysaccharide, microcapsule preparation and zeolite powder are mixed and granulated. The multi-functional bottom modifier has the functions of adsorbing heavy metals, degrading pesticide residues and drug residues, resisting harmful bacteria and viruses, degrading organic matter, reducing the concentration of ammonia nitrogen, nitrite, and hydrogen sulfide in water and bottom, improving bottom quality, and improving water transparency. Function.

Description

technical field [0001] The invention relates to a multifunctional bottom improvement agent and a preparation method thereof, belonging to the technical field of bottom improvement of aquaculture water bodies. Background technique [0002] With the continuous increase of pond culture area in our country, the ecological structure of aquaculture itself and the defects of traditional farming methods have caused many outstanding problems in the aquaculture industry, such as the serious disease of the main cultured species and the outbreak of epidemics; the abuse of fish medicines leads to ecological fragility , the edible safety of aquatic products has declined; with the continuous expansion of the aquaculture area in the inner pond, the discharge of aquaculture wastewater and the accumulation of organic sludge formed by residual bait, feces, and biological debris have continued to increase the organic pollution of the aquaculture water body, and the quality of the aquaculture eco...

AI Technical Summary

Problems solved by technology

Whether it is used alone or in combination, the existing substrate modifiers generally only have a few functions such as degrading organic matter, adsorbing heavy metals, reducing the concentration of ammonia nitrogen, nitrite, and hydrogen sulfide in water, and cannot meet the needs of practical applications.

In particular, the current excessive use of pesticides in agricultural production has resulted in serious pesticide residues, and the water circulation system will also affect the excessive pesticide residues in the aquaculture water; the frequent use of fishery chemicals in fishery production has caused the residues of traditional Chinese medicine in the water to exceed the standard.

In addition, the serious pollution of the external environment and the imbalance of the micro-ecological system in the water body will also lead to the increase of harmful bacteria and viruses, seriously affecting the health of aquatic animals
