Problems solved by technology

However, in the process of artificial breeding, because the density of breeding far exceeds the level of nature, the water body cannot process the excess bait and the excrement of snakeheaded fish, causing the water body to be polluted, the dissolved oxygen to drop, and the ammonia nitrogen index to rise, which is harmful to snakeheaded fish. Adverse effects on growth, which in turn affect farming efficiency

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 use a magnet to separate and remove the green color. Clear liquid, then disperse with 10ml water, collect particles with magnet, remove light green clear liquid, disperse ultrasonically with 5 ml 10wt% trisodium citrate solution, let it stand for 2 hours, re-disperse with 5 ml w...

Embodiment 2

[0034] Basically the same as in Example 1, a microbial water purifying agent for snakehead 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 purifying agent for snakehead 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 snakehead culture water and a preparation method thereof. The preparation method comprises the following steps: adding 20-40 parts by weight of surface-modified C8 and C18 alkyl-chain magnetic silicon balls into 200-400 parts by weight of water; adding 80-100 parts by weight of microbial reagent, including 60-80 parts of Synechococcus, 60-80 parts of Oscillatoria, 10-30 parts of Nitrosococcus, 10-30 parts of Nitrosolobus, 10-20 parts of iron bacteria, 10-20 parts of Leptothrix, 1-5 parts of Thiothrix, 1-5 parts of Vitreoscilla, 30-70 parts of paramecium, 30-70 parts of infusorian, 30-50 parts of Tetraselmis and 30-50 parts of blue algae; and adding 50-90 parts by weight of beef extract peptone agar culture medium, and culturing. The microbial water purifying agent can be added into a snakehead culture tank to achieve the goal of purifying culture tank water.

Description

technical field [0001] The invention relates to a microbial water purifying agent and a preparation method thereof, in particular to a microbial water purifying agent used for snakehead aquaculture 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. Snakefish, also known as snakehead, snakehead, lizard, is ferocious in nature, strong in fecundity, and has a huge appetite. It can often eat all other fish in a certain lake or pond. As early as two thousand years ago, it was listed as the top grade of insects and fish by "Shen Nong's Materia Medica", stone honey, bee cock, beeswax (propolis), oyster, tortoise shell, mulberry octopus, sea clam, Meretrix meretrix, and carp. Black fish is a "dis...
