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

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 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 culture water and a preparation method of the microbial water purifying agent. The preparation method comprises the following steps of adding 30-50 parts by weight of magnetic silicon balls with surfaces modified with C8 and C18 alkyl chains to 300-500 parts by weight of water; adding 100-150 parts by weight of microbial reagents which include the following components in parts by weight: 60-80 parts of rhodopseudomonas palustris, 60-80 parts of synechococcus bacteria, 10-30 parts of nitrococcus, 20-40 parts of nitrobacter Winogradsky, 20-30 parts of pseudomonas aeruginosa, 10-20 parts of paracoccus denitrificans, 3-5 parts of beggiatoa, 3-5 parts of thiobacilli, 30-60 parts of infusorian, 30-60 parts of plantlike flagellate, 30-50 parts of dunaliella tertiolecta and 30-50 parts of chlorella vulgaris; then adding to 60-100 parts by weight of beef extract peptone agar mediums for culture. The microbial water purifying agent disclosed by the invention can achieve the purpose of purifying the water inside a culture pond by being added to a loach culture pond.

Description

Technical field [0001] The invention involves a microbial water purification agent and its preparation method, especially a microbial water purification agent and its preparation method for loach breeding water. Background technique [0002] Names Youyou's new aquaculture varieties have reached the level of large -scale production, forming their own characteristics. [0003] Loach is called "ginseng in water", and it is uncommon in all parts of southern China but it is not common but also distributed in various places.It can be harvested throughout the year. The most summer is a kind of fish with high nutritional value. It is different from other fish. Regardless of the appearance, body shape, and living habits, it is a special kind of trap.Loach likes to inhabit the bottom of the water. It is often on the surface of the mud with plant debris at the bottom of lakes, ponds, ditches, ditches, and paddy fields, and has strong adaptability to the environment.The living water temperat...
