Embodiment 1

[0049] A method for treating fish egg hatching water with ultrasonic waves in cooperation with electrocatalytic equipment, comprising the following method steps:

[0050] A. Collect fertilized eggs, place them in the water body of a plastic container, add chlorine dioxide to make the available chlorine concentration in the water body reach 4ppm, soak and disinfect for 8 minutes;

[0051] B. Place an ultrasonic synergistic electrocatalysis device between the hatching water pipeline and the hatching bucket. The device is equipped with a sealed box integrating the ultrasonic generator (3) and the electrolytic generator (4). The ultrasonic generator (3) and the electrolytic generator The device (4) treats the hatching water at the same time, controls the ultrasonic frequency to 28kHz, the ultrasonic power to 100W, controls the power input voltage of the electrolytic generator to 20V, and the current to 30A; the hatching water enters the hatching bucket after being treated;

Abstract

The invention relates to a method for treating fish roe hatching water through ultrasonic wave synergistic electrocatalysis equipment, and belongs to the technical field of water treatment in aquaculture cultivation industry. The method has the advantages that the fish roe hatching water is treated through the ultrasonic wave synergistic electrocatalysis equipment, the hatching water is purified in a pure physical mode, pathogene and zooplankters, such as bacteria, algae and Cyclops, can be remarkably killed after a single treatment, a part of organic pollutants can be further degraded, so as to ensure that water is healthier, without drug residues and teratogenicity, the traditional chemicals are replaced, and the disadvantages that the chemicals have teratogenicity and drug residues, pollutes water areas, and standing needs to be performed for a certain period after disinfection to enable the chemicals to be volatilized are overcome.

Description

technical field [0001] The invention relates to a method for treating water for aquaculture. More specifically, the invention relates to a method for treating fish egg hatching water with ultrasonic-assisted electrocatalysis equipment, which belongs to the technical field of water treatment for aquatic product aquaculture. Background technique [0002] Bacteria, mold, virus and other pathogens in aquatic nursery production and the invasion of Cyclops often lead to mass death of fry, the most common being neuronecrosis. Once infected, the mortality rate is as high as 90%, which seriously restricts the development of the aquatic industry. Disinfecting fertilized eggs in artificial breeding can block the vertical transmission of pathogens to a large extent. In the early days, malachite green, formaldehyde and other drugs were often used for disinfection at home and abroad, but later they were found to cause fish deformities, high residue, high toxicity and other disadvantages a...
