Problems solved by technology

However, since the amount of feed input is often greater than the intake of grass shrimp, the excess feed can easily cause water quality to decline. If the aquaculture water is not treated in a timely manner, it is easy to cause an increase in the incidence of grass shrimp, a decrease in survival rate, and a decrease in production. And other issues
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 inadaptive symptoms of grass shrimp

Embodiment 1

[0024] (1) Preparation of magnetic silica 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, a microbial water purifier for grass shrimp 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

[0035] Basically the same as in Example 1, a microbial water purifier for grass shrimp 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 used for grass shrimp culture wastewater 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 150-200 parts by weight of microbial reagents: 40-70 parts of Rhodomicrobacteria, 40-50 parts of Rhodobacter sphaericus, 20-40 parts of Nitrosomonas, 20-30 parts of Nitrobacter victoria, 10-30 parts of Pseudomonas stutzeri, 20-40 parts of Phytophthora, Thiobacillus 4- 5 parts, 2-5 parts of Thiobacillus beinerii, 50-80 parts of nematodes, 30-40 parts of vibrating worms, 20-40 parts of Dunaliella, 20-40 parts of chlorella; then add 70-90 parts by weight of beef extract Cultured on peptone agar medium. Putting the microbial water purifying agent of the present invention into the grass shrimp 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 grass shrimp culture 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. Grass shrimp is also known as black-shell shrimp, and its scientific name is Penaeus monodon. It has the characteristics of miscellaneous food, wide-salinity, short breeding cycle, large individual, delicious meat, rich nutrition, and high yield of adult shrimp. It has quite high economic value and has become the key object of breeding. [0003] The main food sources of grass shrimp are miscellaneous fish, shrimp meat, snails, shellfish, bean cake, peanut, ri...
