Problems solved by technology

However, most of the purification agents used for seawater aquaculture purification are mixed and fermented with fresh water, biological bacteria, and nutrients in a ratio of 7:1:2. Preparation, no residue, but the disadvantage is that it consumes a lot of fresh water, and the effect of seawater pollution control is not as good as that of fresh water pollution. At the same time, fresh water has less nutrients, especially calcium and magnesium ions, which cannot supply the normal reproduction of biological bacteria. For nutrition, a certain amount of carbon and nitrogen must be added in proportion; and there is a limit to the reserves of fresh water on the earth. Converting seawater to fresh water not only requires complicated processes but also requires high costs

Embodiment Construction

[0012] The composition and mass percentage of the marine aquaculture biological purifier are: 5ppm-18ppm chitosan oligosaccharide, 50%-70% seawater, 6%-12% biological bacteria liquid, 6%-12% Sucrose and 15%-26% kelp residue, wherein the biological bacteria liquid is a microbial preparation of photosynthetic bacteria, bacillus and lactic acid bacteria, and the chitosan oligosaccharide is made of Alaska snow crab as a raw material, from which chitin is extracted. Chitin is prepared into chitosan by deacetylation, and then the chitosan is reduced to low molecular weight chitosan by enzymatic hydrolysis. Alaskan snow crabs living in the deep sea of ​​the Arctic Ocean are natural marine organisms, non-toxic, and no toxic substances are added during the extraction process, so the produced chitosan oligosaccharides are natural green marine bioactive substances, non-toxic and harmless , No side effects, is a pure natural marine biological products. The molecular weight of chitosan ol...

Abstract

The invention discloses a marine culture biological cleanser and a preparation method thereof. The marine culture biological cleanser comprises the following components in percentage by mass: 5-18 ppm of chitosan oligosaccharide, 50-70% of sea water, 6-12% of biological bacterium solution, 6-12% of sucrose and 15-26% kelp dreg. The biological bacterium solution is a microbial preparation which is compounded and cultured from photosynthetic bacteria, bacillus and lactic acid bacteria. The chitosan oligosaccharide is prepared by the following steps: extracting chitin from Alaska queen crab, deacetylating the chitin to prepare chitosan, and carrying out enzyme digestion on the chitosan to obtain low-molecular weight chitosan. The invention saves the fresh water resources, lowers the cost and enhances the purifying effect for marine culture.

Description

technical field [0001] The invention relates to the field of purifiers, in particular to a marine aquaculture biological purifier and a preparation method thereof. Background technique [0002] At present, with the development of the economy and the improvement of people's living standards, more and more aquatic products have entered thousands of households. In order to meet people's needs, the corresponding scale of aquaculture is also increasing, resulting in increasingly serious water pollution. However, most of the purification agents used for seawater aquaculture purification are mixed and fermented with fresh water, biological bacteria, and nutrients in a ratio of 7:1:2. Preparation, no residue, but the disadvantage is that it consumes a lot of fresh water, and the effect of seawater pollution control is not as good as that of fresh water pollution. At the same time, fresh water has less nutrients, especially calcium and magnesium ions, which cannot supply the normal r...
