Embodiment 1

[0025] Disinfectants used in aquaculture are mainly composed of microbial flocculants and bromochlorohydantoin;

[0026] The disinfectant comprises the following components in terms of weight percentage: 45% of microbial flocculant, 0.05% of bromochlorohydantoin, 30% of surfactant and 24.95% of distilled water.

[0027] The preparation method of this disinfectant is:

[0028] (1) Preparation of microbial flocculant:

[0029] Inoculate Bacillus subtilis in 2 rings of sweet potato processing wastewater medium, and ferment and cultivate at 25°C and 100rpm. After 6 hours of fermentation, supplement 0.2g / LK 2 HPO 4 and 0.1g / LKH 2 PO 4, continue to ferment for 6 hours, supplement 2g / L ammonium bisulfate, continue to ferment for 12 hours, supplement 100mL / L sweet potato processing wastewater, continue to ferment for 12 hours, and obtain fermentation liquid; crop processing wastewater contains rich nutrients, which can be used as flocculation microorganisms for growth and metaboli...

Embodiment 2

[0039] Disinfectants used in aquaculture are mainly composed of microbial flocculants and bromochlorohydantoin;

[0040] The disinfectant comprises the following components in terms of weight percentage: 75% of microbial flocculant, 0.06% of bromochlorohydantoin, 15% of surfactant and 9.94% of distilled water.

[0041] The preparation method of this disinfectant is:

[0042] (1) Preparation of microbial flocculant:

[0043] Inoculate the strains in 2 rings of the sweet potato processing wastewater medium, and ferment and cultivate them at 27°C and 100rpm. After 8 hours of fermentation, supplement 0.3g / LK 2 HPO 4 and 0.15g / LKH 2 PO 4 , continue to ferment for 8 hours, supplement 4g / L ammonium bisulfate, continue to ferment for 16 hours, supplement 150mL / L sweet potato processing wastewater, continue to ferment for 16 hours, and obtain a fermented liquid;

[0044] The fermented liquid is mixed with the respective fermented liquids of Bacillus subtilis and Saccharomyces cere...

Embodiment 3

[0052] Disinfectants used in aquaculture are mainly composed of microbial flocculants and bromochlorohydantoin;

[0053] The disinfectant comprises the following components in terms of weight percentage: 90% of microbial flocculant, 0.01% of bromochlorohydantoin, 5% of surfactant and 4.99% of distilled water.

[0054] The preparation method of this disinfectant is:

[0055] (1) Preparation of microbial flocculant:

[0056] Lactobacillus isolated from yogurt was inoculated into 2 rings of wheat straw processing wastewater medium, and fermented at 28°C and 120rpm. After 12 hours of fermentation, supplemented with 0.5g / LK 2 HPO 4 and 0.2g / LKH 2 PO 4 , continue fermentation for 12 hours, supplement 5g / L ammonium bisulfate, continue fermentation for 18 hours, supplement 200mL / L wheat straw processing wastewater, continue fermentation for 18 hours, and obtain fermentation liquid;

[0057] Add 4 times the volume of distilled water to the strain fermentation broth to dilute, cent...

Abstract

The invention provides disinfectant for aquaculture and a preparation method thereof, and belongs to the field of aquaculture disinfectants. The disinfectant is mainly prepared from microbial flocculant and bromo-3-chloro-5,5-dimethylhydantoin. The preparation method comprises the following steps: diluting a strain fermentation broth with distilled water, centrifuging at 2000-3000rpm to collect supernate, and concentrating the supernate at 40-50 DEG C; adding precooled alcohol into the concentrated solution, standing, centrifuging at 4000-5000rpm to collect precipitate, and suspending in alcohol containing dihydroxyethylglycinate and sugar alcohol; sanding at negative 10-negative 15 DEG C, and centrifuging at 4000-5000rpm to collect precipitate; and drying in vacuum to obtain the microbialflocculant. The disinfect has the advantages of safety, no toxicity, environmental friendliness, complete water purification / disinfection and the like; the preparation method of the disinfect has simple process and low cost, and can be widely applied to aquaculture or water environment improvement of other fields.

Description

technical field [0001] The invention belongs to the field of aquaculture disinfectant, in particular to a disinfectant for aquaculture and a preparation method thereof. Background technique [0002] Disinfectant is the most commonly used water quality improver in the aquaculture industry. Its main function is to agglomerate the suspended particles formed by feed debris, plankton corpses, bottom sludge, etc. To achieve the purpose of purifying aquaculture water. The quality of the disinfectant is mainly measured by indicators such as turbidity removal rate, COD removal rate, suspended solids removal rate, and color removal effect. Excellent water purification products can quickly improve deteriorating water quality, prevent disease occurrence, and improve breeding efficiency. [0003] Therefore, fishery medicine enterprises and fishery scientific research units have attached great importance to the research and development of such products in recent years. There are many v...
