Problems solved by technology

[0004] In the current breeding technology, there are mainly natural feeds (duckweed, water peanuts, bitter grass, wild fish, snails, mussels, etc.), artificial feeds (tofu, bean dregs, bean cakes, wheat, etc.) and compound feeds for hairy crabs. etc., but because the amount of feed is often greater than the food intake of hairy crabs, it is easy to cause water quality to decline.

Example Embodiment

[0024] Example 1:

[0025] (1) Preparation of magnetic silicon balls with surface modified C8 and C18 alkyl chains:

[0026] (1-1) Synthesis of Fe by hydrothermal method 3 O 4 Magnetic nanoparticles: add 1 gram of FeCl 3 ·6H 2 O, dissolved in 30ml ethylene glycol, add 4g of anhydrous sodium acetate, reaction temperature is 200℃, reaction time is 12 hours, and Fe is produced 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 10g of water to obtain Dispersion A. Take a centrifuge tube, add 3 g of the above Dispersion A, add 5ml of 2M HCl solution and sonicate for 8min, then separate the green with a magnet Disperse the clear liquid with 10ml water, then collect the particles with a magnet, remove the light green clear liquid, disperse with 5ml 10wt% trisodium citrate solution ultrasonically, let stand for 2h, and re-disperse with 5ml water to obtain dispersion B ;

Example Embodiment

[0033] Example 2:

[0034] Basically the same as Example 1, the microbial water purifier for hairy crab breeding water was prepared, except that the surface modifiers in step (1-4) are different. In Example 2, 0.3 g of dimethyloctylsilane was used as the surface modifier.

Example Embodiment

[0035] Example 3:

[0036] Basically the same as Example 1, the microbial water purifier for hairy crab breeding water was prepared, except that the surface modifiers in step (1-4) are 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 hairy crab culture water and a preparation method of the agent. The preparation method comprises the following steps: adding 20-40 parts by weight of magnetic silicon spheres of which the surface is modified with C8 and C18 alkyl chains to 200-400 parts by weight of water; adding 130-180 parts by weight of microbial reagents which include 30-60 parts of synechococcus, 30-50 parts of rhodospirillum, 10-30 parts of nitrococcus, 10-30 parts of nitrospina, 10-20 parts of thiobacillus denitrificans, 10-20 parts of raw iron bacteria, 3-5 parts of beggiatoa, 1-3 parts of vitreoscilla, 30-70 parts of phytoflagellate, 30-50 parts of zooflagellate, 20-50 parts of tetraselmis and 20-50 parts of chlorella; next, adding 60-80 parts by weight of beef extract peptone agar culture medium for culturing. The microbial water purifying agent is put into a hairy crab culture pond to purify 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 for hairy crab 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. Hairy crabs, also known as Chinese mitten crabs, river crabs, hairy crabs, clear water crabs or crabs, are delicious and nutritious. They are economical crabs and one of the traditional valuable aquatic products in China. It is widely distributed along the long coastline from Liaohe River in the north to the Pearl River in the north of China. Among them, the Yangtze River system has the largest output and the most delicious taste, and the Yangcheng Lake hairy crab i...
