Problems solved by technology

Because the density of breeding far exceeds the natural level, the water body cannot process the excess bait and loach excrement, resulting in water pollution, a decrease in dissolved oxygen, and an increase in ammonia nitrogen index, which has an adverse effect on the growth of loach
In the current aquaculture technology, because the aquaculture water cannot be treated, it is easy to cause problems such as an increase in the incidence of loach, a decrease in the survival rate, and a decrease in production.
The conventional solution is to change the water at intervals, but on the one hand, changing the water will increase the production cost, and on the other hand, it will easily cause the inadaptive symptoms of the loach

Embodiment 1

[0025] (1) Preparation of magnetic silica spheres with surface-modified C8 and C18 alkyl chains:

[0026] (1-1) Synthesis of Fe by hydrothermal method 3 o 4 Magnetic nanoparticles: 1 g of FeCl 3 ·6H 2 O, dissolved in 30ml of ethylene glycol, adding 4 grams of anhydrous sodium acetate, the reaction temperature is 200 ° C, the reaction time is 12 hours, and Fe is generated 3 o 4 magnetic nanoparticles;

[0027] (1-2) The above Fe 3 o 4 Wash the magnetic nanoparticles with water to remove water-soluble impurities, and then disperse them in 10 g of water to obtain dispersion A. Take a centrifuge tube, add 3 g of the above dispersion A, add 5 ml of 2M HCl solution and sonicate for 8 minutes, and then separate and remove the green clear liquid with a magnet. Then disperse with 10ml of water, collect the particles with a magnet, remove the light green clear liquid, disperse with 5ml of 10wt% trisodium citrate solution ultrasonically, let stand for 2h, and disperse with 5ml of ...

Embodiment 2

[0034] Basically the same as in Example 1, a microbial water purifier for loach aquaculture water was prepared, the only difference being that the surface modification agent in step (1-4) was different. In Example 2, 0.3 g of dimethyloctylsilane was used as the surface modifier.

Embodiment 3

[0036] Basically the same as in Example 1, a microbial water purifier for loach aquaculture water was prepared, the only difference being that the surface modification agent in step (1-4) was different. In Example 3, 0.3 g of octadecyltriethoxysilane was used as the surface modifier.

Abstract

The invention discloses a microbial water purifying agent for loach breeding water and a preparation method thereof. The preparation method: add 30-50 parts by weight of magnetic silicon spheres with surface-modified C8 and C18 alkyl chains to 300-500 parts by weight of water; add 100-150 parts by weight of microbial reagent: Rhodopseudomonas palustris 60- 80 parts, 60-80 parts of Synechococcus, 10-30 parts of Nitrococcus, 20-40 parts of Nitrobacter Vickers, 20-30 parts of Pseudomonas aeruginosa, 10-20 parts of Paracoccus denitrification, Beria 3-5 parts of Totoia, 3-5 parts of Thiobacillus, 30-60 parts of ciliates, 30-60 parts of Phytoflagellates, 30-50 parts of Dunaliella, 30-50 parts of Chlorella; add 60-100 parts parts by weight beef extract peptone agar culture medium. Putting the microbial water purifying agent of the present invention into the loach culture pond can achieve the purpose of purifying the water in the culture pond.

Description

technical field [0001] The invention relates to a microbial water purifier and a preparation method thereof, in particular to a microbial water purifier used for loach breeding water and a preparation method thereof. Background technique [0002] In recent years, the rapid advancement of high-efficiency agriculture has led to the rapid development of special aquaculture. Famous, special and high-quality new aquaculture species have reached the level of large-scale production and formed their own characteristics. [0003] Loach is called "the ginseng in the water", and it is distributed in various places in southern China, but it is not common in the north, but it is also distributed in various places. It can be harvested throughout the year, most in summer, and is a fish with high nutritional value. It is different from other fish in terms of appearance, body shape, and living habits. It is a special kind of loach. Loach likes to inhabit the bottom of still water, often ap...
