Problems solved by technology

[0002] At present, the water quality regulation of pond aquaculture mainly depends on the self-purification of water body, water exchange and mechanical oxygenation. When the content of nitrite and ammonia nitrogen exceeds the standard, it will cause a large number of deaths of aquatic animals, directly affect the economic benefits of aquaculture and human health, and become the biggest headache for aquaculture owners, and it is difficult to maintain good aquatic products only by self-regulation. Breeding ecological environment
With the development of water treatment technology, the application of water treatment technology in the removal of nitrite and ammonia nitrogen in aquaculture has been gradually promoted. At present, the methods of using water treatment technology to remove nitrite and ammonia nitrogen in aquaculture mainly include physical adsorption. These methods have certain effects on the removal of nitrite and ammonia nitrogen in aquaculture, but there are certain defects in these methods in the process of application.
The treatment capacity of the physical adsorption method is limited, and it is easy to rebound; some chemical substances are highly toxic when treated by chemical methods, which have a strong killing effect on aquaculture animals and planktonic algae, and the residual amount is large; Nitrate removal is too slow

Embodiment

[0024] Put the hydrogen peroxide into the wide-mouthed barrel at a rate of 3 kg / mu, cover the opening of the wide-mouthed barrel with a sponge, and then tie the wide-mouthed barrel to the floating leg of the aerator with a 1-meter-long string, so that Submerge the wide-mouth bucket in water, start the aerator, the hydrogen peroxide slowly spreads around through the sponge and the water flow, during the diffusion process, the hydrogen peroxide decomposes into water and oxygen, and the oxygen oxidizes nitrite and ammonia nitrogen into nitrate. After 3 days, press The amount of 1.5 kg / mu will evenly sprinkle the cultured photosynthetic bacteria liquid into the culture pond, and the nitrate will be absorbed and utilized by the photosynthetic bacteria, which is beneficial to the growth of planktonic algae and provides nutrients for aquatic animals.

Abstract

A process for removing nitrite and ammoniacal nitrogen in aquatic products cultivation includes loading H2O2 into an open container, enclosing the container by an osmotic film, attaching the container to an oxygen-enriching machine in water of pond, turning on the machine for slowly diffusing the H2O2 to decompose it into H2O and O2, oxidizing the nitrite and ammoniacal nitrogen to become nitrate by said O2, and adding photosynthesizing bacteria to absorb the nitrate.

Description

technical field [0001] The invention relates to a method for removing nitrite and ammonia nitrogen in water, in particular to a method for removing nitrite and ammonia nitrogen in aquaculture. Background technique [0002] At present, the water quality regulation of pond aquaculture mainly depends on the self-purification of water body, water exchange and mechanical oxygenation. When the content of nitrite and ammonia nitrogen exceeds the standard, it will cause a large number of deaths of aquatic animals, directly affect the economic benefits of aquaculture and human health, and become the biggest headache for aquaculture owners, and it is difficult to maintain good aquatic products only by self-regulation. Breeding ecological environment. With the development of water treatment technology, the application of water treatment technology in the removal of nitrite and ammonia nitrogen in aquaculture has been gradually promoted. At present, the methods of using water treatment...
