Problems solved by technology

The control of aquaculture diseases in my country is mainly based on drug prevention and control. In addition, the technology is relatively single, and the culture and professional quality of the farmers are not high, and the blind use of drugs in production leads to repeated pollution of water bodies. On the other hand, a large number of frequent use of drugs It is easy for pathogenic microorganisms to develop drug resistance, thus losing the therapeutic effect

preparation example Construction

[0054] The preparation method of the extract of the scallop leaf is as follows: take the scallop and place it at 50° C. to dry for 4 hours, crush it to 100 meshes to obtain the scallop powder, add 50 wt % ethanol aqueous solution which is 4 times the mass of the scallop powder, perform supercritical extraction for 3 hours, extract The pressure is 20MPa, the extraction temperature is 40°C, the separation pressure is 5MPa, and the separation temperature is 35°C to obtain a supercritical extract and a supercritical raffinate; add 50 wt% of 20 times the mass of the supercritical raffinate to the above supercritical raffinate The methanol aqueous solution was placed at 55°C for ultrasonic treatment for 20 minutes, the ultrasonic power of the ultrasonic treatment was 350W, and the ultrasonic frequency was 30kHz to obtain an ultrasonic extract; the above-mentioned supercritical extract and ultrasonic extract were combined, filtered through a 250-mesh filter cloth, The obtained filtrat...

Embodiment 1

[0063] The purification agent for aquaculture is prepared from the following raw materials in parts by mass: 35 parts of activated carbon, 15 parts of compound enzyme agent, 52 parts of curing agent, 1.6 parts of scallop leaf extract, 1.6 parts of watercress leaf extract, phoenix lotus 1.6 parts of root extract, 15 parts of polyaluminum chloride, 5 parts of sodium alginate, 3 parts of sodium dodecylbenzenesulfonate.

[0064] The compound enzyme agent is formed by mixing protease, lipase and laccase in a mass ratio of 2:1:1.

[0065] The curing agent is prepared by mixing montmorillonite, modified bentonite and chitosan modified diatomite in a mass ratio of 1:1:1.

[0066] The preparation method of described gac is:

[0067] Ⅰ. Dry the coconut shell at 50°C for 7 hours, crush it to 400 mesh, and obtain the pretreated raw material powder;

[0068] Ⅱ. The above-mentioned pretreated raw material powder is activated by heating up to 700°C at a rate of 15°C / min under the protectio...

Embodiment 2

[0087] It is basically the same as Example 1, the only difference is that the purifying agent for aquaculture is prepared from the following parts by mass of raw materials: 35 parts of activated carbon, 15 parts of composite enzyme agent, 52 parts of curing agent, and 2.4 parts of scallop leaf extract , 2.4 parts of watercress leaf extract, 15 parts of polyaluminium chloride, 5 parts of sodium alginate, 3 parts of sodium dodecylbenzenesulfonate.

[0088] The preparation method of the clarifier for aquaculture comprises the following steps:

[0089] Ⅰ. Weigh each raw material component by mass parts;

[0090] Ⅱ. Add water with 12 times the mass of the compound enzyme to the compound enzyme, stir at 30°C and 200r / min for 20min to obtain a mixed enzyme liquid, then add activated carbon to the mixed enzyme liquid, and stir at 30°C and 200r / min / min under the condition of constant temperature adsorption for 65min, that is, a mixed solution containing enzyme-loaded activated carbon...

Abstract

The invention discloses a purifying agent for aquaculture and a preparation method of the purifying agent. The purifying agent for aquaculture includes the following raw materials: in parts by mass, 30-42 parts of activated carbon, 12-18 parts of composite enzyme, 50-64 parts of a curing agent, 3-6 parts of plant extract, 12-22 parts of a flocculant, 3-6 parts of sodium alginate and 2-5 parts of sodium dodecylbenzenesulfonate. Through the purifying agent for aquaculture, the content of organic pollutants, heavy metal ions and other pollutants in a water body can be reduced, suspended solids and harmful algae in the water can be removed, micro-ecological balance is promoted, stabilization of the aquaculture water body is achieved, and the quality and safety of aquaculture products are improved; and the preparation method is simple, and is suitable for large-scale production and application.

Description

technical field [0001] The invention relates to the technical field of aquaculture water purification, in particular to a purifying agent for aquaculture and a preparation method thereof. Background technique [0002] In recent years, the scale of aquaculture has expanded rapidly, and the aquaculture technology has gradually improved and matured. With the large-scale development of the aquaculture industry, the aquaculture area and aquaculture intensity are increasing, the ecological environment of aquaculture is deteriorating, and the diseases are becoming more and more prominent, especially the organic matter in the water body. These organic substances mainly come from the excrement and feed of animals in the water body. After slowly diffusing in the water body, a large number of small organic particles are formed. After soaking for a long time, the pollution of the water quality is increased, and it also provides rich nutrients for the reproduction of bacteria. The aquac...
