Problems solved by technology

The current common treatment methods, such as general physical and chemical treatment or single microbial strain treatment, compound microbial preparations such as yeast (EM), etc., have certain limitations. These water quality improvers have a single effect and poor antibacterial effect. It does not have the insecticidal function, or the water transfer effect is unstable, and there is no multifunctional aquaculture water improver that can detoxify, dissolve oxygen, stabilize water, and nourish.
[0004] The prior art, such as the Chinese invention patent application publication number CN 105995224 A, discloses a preparation method of a multifunctional aquaculture water body improver. The shredded tobacco, tea seed cake, vinegar grains, and EM active calcium liquid are co-fermented. The water quality improver is made by mixing and granulating the technology. The water quality improver is combined with the theory of microecology, and the effects of antibacterial and disease prevention, and nutritional calcium supplementation of the water quality improver are outstanding. Plankton does not have significant benefits, and the effect of water regulation is unstable

Embodiment 1

[0018] The preparation method of the multifunctional aquaculture water body improver comprises the following specific steps:

[0019] 1) Mix 14 parts of weathered coal, 7 parts of alkali metal silicate and 2 parts of deionized water, and react at a temperature of 70°C for 50 minutes to obtain a humic acid solution. The prepared humic acid solution is weakly alkaline, which can make The silicic acid and humic acid in the solution are not easy to settle, which can effectively reduce the accumulation of the modifier in the water body. At the same time, it contains silicon ions, which have the nutritional value of silicon fertilizer. It not only provides nutrients such as planktonic organic matter and silicon, but also It has the function of cultivating algae and cultivating algae;

[0020] 2) Dissolve humic acid in 5% NaOH solution, add to the reaction device and heat for 10 minutes, then add polyethylene glycol with 5% humic acid weight, under nitrogen protection, temperature 12...

[0024] The preparation method of the multifunctional aquaculture water body improver comprises the following specific steps:

[0025] 1) Mix 14 parts of weathered coal, 7 parts of alkali metal silicate and 2 parts of deionized water, and react at a temperature of 90°C for 70 minutes to obtain a humic acid solution;

[0026] 2) Dissolve humic acid in 8% NaOH solution, add to the reaction device and heat for 15 minutes, then add polyethylene glycol with 7% humic acid weight, under nitrogen protection, temperature 135°C, heat reaction for 1.5 hours to obtain grafted Humic acid modified by copolymerization reaction;

[0027] 3) Add 0.12 parts of Al 2 (SO 4 ) 3 , 0.1 parts of ClO 2 Add 0.08 parts of 1-hydroxydodecyltrimethylammonium bromide to bentonite, and react for 40 minutes at a pH value of 9.0, adjust the pH to 4.5, place it in a microwave oven with a power of 1500W, and heat it by irradiation 20min, synthetic inorganic-organic bentonite, above-mentioned ClO 2 ionized H...

[0030] The preparation method of the multifunctional aquaculture water body improver comprises the following specific steps:

[0031] 1) Mix 14 parts of weathered coal, 7 parts of alkali metal silicate and 2 parts of deionized water, and react at a temperature of 80°C for 60 minutes to obtain a humic acid solution;

[0032] 2) Dissolve humic acid in 10% NaOH solution, add to the reaction device and heat for 20 minutes, then add polyethylene glycol with 9% humic acid weight, under nitrogen protection, temperature 150°C, heat reaction for 2 hours, and obtain graft copolymerized Reaction-modified humic acid, the above-mentioned polyethylene glycol contains 0.08% ethyl propionate by weight, and the added ethyl propionate can assist heating to destroy the structure of polyethylene glycol, making the polyethylene glycol part weak The bond is broken faster, the internal hydrophilic polar group is exposed to the surface of the molecule, and quickly dissolves in water, thereby accelera...

Abstract

The invention discloses a method for preparing a multifunctional aquatic water modifier. The method concretely comprises the following steps: reacting weathered coal, alkali metal silicate and deionized water to obtain a humic acid solution; dissolving the prepared humic acid in a NaOH solution, heating and reacting the obtained solution and polyethylene glycol to obtain modified humic acid; adding Al2(SO4)3 and 1-hydroxydodecyltrimethylammonium bromide to bentonite, and carrying out irradiation heating to synthesize inorganic-organic bentonite; and carrying out multiphase mixing to form the water modifier. The preparation method has the advantages of simplicity, feasibility, and easiness in industrial production; and the prepared product has detoxifying, oxygen dissolving, water stabilizing and nourishing effects, and can effectively improve the quality of water, reduce nutrient elements in the water, reduce aquatic product diseases, increase nutrient elements in the water and increase the content of algae and planktonic aquatic creatures as natural baits in order to promote the growth and reproduction of aquatic products and increase the aquaculture production and the economic benefit.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a preparation method of an aquaculture water improver with the functions of nutrition, detoxification, water stabilization and oxygen dissolution. Background technique [0002] my country has a long history of pond aquaculture. In recent decades, with the continuous increase of pond aquaculture area in our country, the ecological structure of aquaculture itself and the defects of traditional aquaculture methods have caused many outstanding problems in the aquaculture industry, such as the disease of the main aquaculture species. Severe and explosive epidemic; 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, the concentration of nutrients and organic matter in the water body increased, and the transparency decreased. The or...
