Problems solved by technology

However, since the amount of feed input is often greater than the amount of food consumed by sea bass, the excess feed and excrement of sea bass cannot be effectively treated, which will easily lead to a decline in water quality. decline and other problems seriously affect the breeding
The conventional solution is to change the water at intervals, but on the one hand, changing the water increases the production and management costs, and on the other hand, it is easy to cause discomfort symptoms of perch

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 purifier for perch 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 perch 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 weever farming wastewater and a preparation method of the microbial water purifying agent. The preparation method comprises the following steps: adding 40-60 parts by weight of magnetic silica beads with surface modification of C8 and C18 alkyl chains into 200-300 parts by weight of water; adding 200-300 parts by weight of a microbial reagent comprising 50-80 parts of oscillatoria, 40-80 parts of rhodomicrobium, 40-60 parts of nitrosococcus, 30-50 parts of nitrospina, 30-40 parts of crenothrix, 30-40 parts of pseudomonas aeruginosa, 3-6 parts of leucothrix, 3-6 parts of beggiatoa, 40-60 parts of zooflagellates, 40-60 parts of suctorians, 40-50 parts of dunaliella and 40-50 parts of blue-green algae; and further adding 80-100 parts by weight of a beef extract peptone agar culture medium for culture. By putting the microbial water purifying agent disclosed by the invention into a weever farming pond, the purpose of purifying the water in the farming pond can be achieved.

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 for perch 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] Perch belongs to Perciformes, perch subfamily, euryhaline fish. It is distributed along the coast of our country and is rich in resources. Perch has the characteristics of fast growth, wide adaptability, strong disease resistance, and delicious meat. Sea bass is rich in protein, vitamin A, B vitamins, calcium, magnesium, zinc, selenium and other nutrients; it has the effects of nourishing the liver and kidney, benefiting the spleen and stomach, ...
