Problems solved by technology

However, since the amount of feed put in is often greater than the food intake of rice field eels, if the excess feed is not effectively treated, it will easily lead to a decline in water quality, and the relative amount of rice field eel excreta is relatively large. Rate reduction, production decline and other issues
The conventional solution is to change the water at intervals, but on the one hand, changing the water increases production and management costs, and on the other hand, it is easy to cause unsuitable symptoms of rice field eels

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 eel culture 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 eel culture 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 microbiological water purifying agent for ricefield eel breeding water and a preparation method of the microbiological water purifying agent. The preparation method comprises the steps of adding 30-50 parts by weight of magnetic silica spheres with C8 and C18 alkyl chains modified on surfaces into 150-250 parts by weight of water; adding 150-250 parts by weight of microbiological reagents including 40-50 parts of rhodospirillum, 40-60 parts of rhodopseudomonas, 30-50 parts of Ni-trosolobus, 30-40 parts of nitrococcus, 20-30 parts of thiobacillus denitrificans, 30-40 parts of sphaerotilus natans, 2-4 parts of vitreoscilla, 2-4 parts of thiobacillus, 30-50 parts of paramecium, 40-60 parts of nematode, 40-50 parts of platymonas subcordiformis and 40-50 parts of cyanobacteria; and adding 60-80 parts by weight of beef extract peptone agar, and culturing in a culture medium. The aim of purifying water in a breeding pond can be achieved after the microbiological water purifying agent disclosed by the invention is added into a ricefield eel breeding pond.

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 in eel 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. [0003] Swamp eel belongs to the class of fish, synbranchial order, synbranchial family, and swamp eel subfamily, also known as squid, Luo eel, snake fish, and long fish (in northern Jiangsu). Field eels are widely distributed and are distributed almost everywhere in China. The nutritional value of rice field eel is extremely high. According to American experimental research data, regular intake of lecithin can improve memory by 20%. Therefore, eating ...
