Problems solved by technology

However, since the amount of feed input is often greater than the feed intake of Penaeus vannamei, the surplus feed can easily cause water quality to decline if it is not treated effectively. production decline, etc.
The conventional solution is to change the water at intervals, but on the one hand, changing the water will increase the production and management costs, and on the other hand, it will easily cause the incompatibility symptoms of Penaeus vannamei

Embodiment 1

[0024] (1) Preparation of magnetic silicon spheres with surface-modified C8 and C18 alkyl chains:

[0025] (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;

[0026] (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

[0033] Basically the same as in Example 1, the microbial water purifying agent used for the culture water of Penaeus vannamei was prepared, the only difference being that the surface modifier was different in step (1-4). In Example 2, 0.3 g of dimethyloctylsilane was used as the surface modifier.

Embodiment 3

[0035] Basically the same as in Example 1, the microbial water purifying agent used for the culture water of Penaeus vannamei was prepared, the only difference being that the surface modifier was different in step (1-4). In Example 3, 0.3 g of octadecyltriethoxysilane was used as the surface modifier.

Abstract

The invention discloses a microorganism water-purifying agent used for culture water of penaeus vannamei boone, and a preparation method thereof. The preparation method comprises the steps of adding 30-50 parts by weight of a magnetic silicon spheres with surface modified by C8 and C18 alkyl chains into 300-500 parts by weight of water; adding 150-200 parts by weight of a microorganism reagent, the microorganism reagent comprising, by weight, 50-80 parts of rhodomicrobium, 50-80 parts of rhodobacter spheroids, 20-40 parts of nitrosomonas, 20-40 parts of nitrosospira, 10-30 parts of pseudomonas stutzeri, 20-40 parts of sphaerotilus natans, 4-8 parts of thiobacillus, 4-8 parts of thioploca, 50-80 parts of nematode, 50-80 parts of tubifex, 20-40 parts of dunaliella and 20-40 parts of chlorella; and then adding 70-90 parts by weight of a beef extract peptone agar medium for culturing. By adding the microorganism water-purifying agent provided by the invention in a culture pool of the penaeus vannamei boone, an object of purifying the culture water can be achieved.

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 culture water of Penaeus vannamei 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. Penaeus vannamei Boone, whose scientific name is Penaeus vannamei, belongs to Arthropoda, Crustacea, Decapod, Swimming suborder, Penaeidae, and Penaeus. It is a wide-temperature and wide-halt tropical shrimp. Commonly known as white-legged shrimp and white-legged shrimp, the longest adult can reach 24cm, the carapace is relatively thin, the normal body color is light blue-gray, and there are no markings on the whole body. Penaeus vannamei is one of the...
