[0002] The core of fish farming is to achieve fish breeding, feeding and stocking through scientific management, the key lies in species selection, bait management and water quality control.

[0003] In the process of fish farming, cleaning fish feces has always been a relatively important task, which is beneficial to the regulation of water quality, reducing the amount of water input in the process of fish farming, so that water can be reused for fish farming. If the fish feces are not cleaned properly, a large amount of algae will proliferate in the water, causing the number of harmful microorganisms to increase sharply, which may affect the health of the fish in the water. Harmful microorganisms can cause some fish to become sick, such as water mold disease, pepper disease, bulging eyes, congestion and descaling, head hole disease, gill rot disease, enteritis, etc. Summary of the Invention

[0009] As a further optimization scheme of the present invention, the preparation process of the micro-carrier is as follows: (1) adding hydrogenated rosin and polyurethane to a heating container, heating at 60°C for 10 minutes to obtain a polymer mixed material, and keeping it warm at 80°C for standby use; (2) mixing calcium cyclopentaneate powder, azodicarbonamide powder and volcanic rock powder, pouring them into the polymer mixed material, stirring at 15-30r / min for 10-20 minutes to obtain an electrospinning stock solution; (3) injecting the electrospinning stock solution into a spinning machine for spinning, and stopping spinning when the cumulative spinning thickness reaches 0.01mm to obtain a silk sheet; (4) applying vaseline between two silk sheets to form a 1mm×1mm diamond isolation module, the four corners of each diamond isolation module are connected, and the diamond isolation modules are flatly distributed in a dotted manner to obtain a micro-carrier.

[0010] As a further optimized solution of the present invention, the preparation process of the bentonite base is as follows: montmorillonite, albite and kaolin are crushed and ground into powder, and the powder is passed through a 60-mesh sieve to obtain the bentonite base.

[0011] As a further optimized solution of the present invention, the preparation process of the saprophytic agent is as follows: Bacillus natto, Bacillus cereus, Nitrosomonas and cassava starch are mixed to obtain the saprophytic agent.

[0012] As a further optimization solution of the present invention, the mass ratio of montmorillonite, albite and kaolin is 3:1:1.

[0013] As a further optimized solution of the present invention, the preparation process of the volcanic rock powder is: crushing the volcanic rock, grinding it into powder, and passing it through a 60-mesh sieve to obtain the volcanic rock powder.

[0014] The present invention also provides a method for preparing a natural sodium bentonite-based fish manure purification material, comprising the following steps:

[0015] Method for carrying bentonite base on a micro-carrier: injecting the bentonite base into the micro-carrier and cutting it into 1.5mm×2mm rectangular pieces by hot melt cutting, so that the micro-carrier carries the bentonite base; a 1mm×1mm diamond-shaped isolation module between the two pieces of silk is used to carry the bentonite base;

[0016] Method for attaching saprophytic agent to micro-support frame: spray saprophytic agent on the outer surface of micro-support frame after supporting bentonite base by using sprayer.

[0017] As a further optimized solution of the present invention, 0.1 mg of saprophytic agent is sprayed on the outer surface of the micro-carrier per square centimeter.
