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 survi

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 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

[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 for grass shrimp farming wastewater and a preparation method of the microbial water purifying agent. The preparation method comprises the following steps: adding 30-50 parts by weight of magnetic silica beads with surface modification of C8 and C18 alkyl chains into 300-500 parts by weight of water; adding 150-200 parts by weight of a microbial reagent comprising 40-70 parts of rhodomicrobium, 40-50 parts of rhodobactersphacroides, 20-40 parts of nitrosomonas, 20-30 parts of nitrobacterwinogradskyi, 10-30 parts of pseudomonasstutzeri, 20-40 parts of leptothrix, 4-5 parts of thiobacillus, 2-5 parts of beggiatoa, 50-80 parts of nematodes, 30-40 parts of aeolosomatidaes, 20-40 parts of dunaliella and 20-40 parts of chlorella; and further adding 70-90 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 grass shrimp 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 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...
