Aeration refers to the method of removing harmful gases such as chlorine and ammonia in the water body by increasing the oxygen content of the water body. Aeration is mainly divided into two types, one is static, and the other is the mechanical stirring of the water. If you use tap water to raise fish, you can use the static method to let the water body stand still for 48 hours, so that harmful gases in the water body can escape. Through the aerator, the upper and lower water layers of the water body in the pond can be convected, which not only helps the harmful gases in the water body escape quickly but also increases the dissolved oxygen in the water body, which has a very significant effect on improving water quality. Usually, impeller-type aerators are mainly used for fish farming in ponds, while water wheel aerators are required for eel ponds.
In the process of aquaculture, certain suspended solids, solid wastes, and large aquatic organisms will be formed in the water body. If you want to remove them, you can use filtration. Usually, sand filters, mechanical filters, and pressure filters can be used, all of which can play a very significant effect.
Suspended solids in the water body will have extremely adverse effects on aquaculture. These suspended solids will be adsorbed on the gills of fish, thereby affecting the normal breathing of fish. At the same time, the suspended matter will also increase the viscosity and turbidity of the water body, which will seriously affect the hatching of the fry. And through sedimentation treatment, the suspended solids in the water body can be reduced, and the harm of suspended solids to fish can be reduced.
The application of solid-phase substances such as silica gel and activated carbon can adsorb toxic substances in water bodies, such as ammonia and nitrogen. For heavy metal ions in water, heavy metal adsorbents can be used for adsorption. The use of adsorbents with a particle size of 0.3-1.2 mm can have a good adsorption effect on various heavy metals in the water body, which will not cause secondary pollution to the water body, and can also effectively improve the water quality.
This technology mainly targets the active substances on the surface of water bodies. By ventilating the water, corresponding bubbles are generated in the water body, and then the bubbles absorb the active substances on the surface of the water body and then form foam, which is suspended on the surface of the water body. This method has a very significant effect on suspended solids and dissolved solids in water. However, foam analysis technology is not suitable for freshwater, usually only in seawater, and the salinity must be greater than 5/1000.
Flocculation refers to the application of organic or inorganic chemical reagents to agglomerate colloids and tiny particles in water into large flakes, thereby improving their own quality and accelerating precipitation. At present, in the process of aquaculture, the widely used flocculants include polymer flocculants, aluminum salts, etc., all of which can achieve ideal results.
The function of neutralization is to improve the pH value of the water body and ensure that the water is neutral or weakly alkaline. In the process of neutralization, more lime water and quicklime are used, which can not only improve the pH value, but also increase the calcium content of the water body, and have the effect of killing pathogens. If the pH of the water is too high, neutralize it with acetic acid or oxalic acid.
Through oxidation and reduction, it can not only reduce the content of toxic substances in the water body, but also play a role in killing pathogenic bacteria, such as bleaching powder, ozone, etc., and undergo redox reactions with sulfur ions and cyanide ions in the water. Ozone can remove color, organic matter, odor, and iron in the water. At the same time, ozone also has a strong bactericidal effect. However, since ozone can not only kill harmful bacteria but also kill beneficial bacteria, it should be used with caution.
Photosynthetic bacteria are a type of autotrophic microorganisms that use small molecular organic matter or carbon dioxide as a carbon source, light as an energy source, and hydrogen sulfide as a hydrogen body. Reproductive photosynthetic bacteria do not require high oxygen, as long as there is light and water, they can survive and reproduce. During the survival and reproduction of photosynthetic bacteria, they can absorb harmful substances such as hydrogen sulfide and ammonia nitrogen, and then play a role in purifying water. At the same time, the increase in the number of photosynthetic bacteria can also inhibit the reproduction of pathogens, thereby reducing the probability of disease occurrence in aquaculture products, which is of great significance for ensuring the quality of aquaculture products and improving the income of aquaculture.
When aquatic plants perform photosynthesis, they can absorb nitrogen and carbon dioxide in the water body and can purify the water body. For example, in the breeding process of juvenile soft-shelled soft-shelled turtles, if some water hyacinths are cultivated in the water, it can not only increase the dissolved oxygen in the water, but also reduce the content of ammonia, nitrogen, and organic matter in the water, which not only purifies the water, improves The effect of water quality can also promote the growth of juvenile soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shell turtle to a certain extent, increasing the income of breeding.
In the process of aquaculture, waste will inevitably be produced, which will contain a large number of nutrients and organic matter, which is very unfavorable to aquaculture. However, these nutrients and organic matter are necessary for the growth of vegetables and flowers. Therefore, combining aquaculture with vegetable and flower planting can not only purify water bodies and improve water quality, but also improve the quality of vegetables and flowers and increase economic benefits.
What is the function of an aquaculture dissolved oxygen meter? The main functions of the dissolved oxygen meter in aquaculture include: measuring oxygen content, such as detecting and adjusting the oxygen content in water to maintain suitable ecological and growth conditions for aquaculture.
