Hydrodynamic force circulation oxygen enrichment device

Technical Field

The utility model relates to a water body circulation oxygenation device, and belongs to the technical field of water treatment.

With the acceleration of urbanization pace and the improvement of industrialization degree, the direct discharge of excessive living pollution causes water eutrophication, even causes the water in a river to blacken and stink, leads the water to lose the use function completely, and forms black and stink water. The black and odorous water body not only causes serious damage to aquatic organisms and an ecological system, but also brings great influence on the living environment and health of human beings.

When the water body is polluted by organic matters and reducing substances, the dissolved oxygen in the water body is reduced. The dissolved oxygen in the water body has a vital influence on the biological existence in the water, when the dissolved oxygen is lower than 2mg/L, the fish can be suffocated and die, when the consumption rate of the Dissolved Oxygen (DO) is greater than the rate of dissolving oxygen into the water body, the content of the dissolved oxygen can approach to 0, anaerobic bacteria can be propagated at the moment, and the water body is deteriorated, so the dissolved oxygen can reflect the pollution of the water body, particularly the degree of organic matter pollution, which is an important index of the water body pollution degree and also is a comprehensive index for measuring the water quality. In the process of pond aquaculture, due to the relatively closed characteristic of a pond, the water body flows unsmoothly, and in addition, the environment is continuously deteriorated in the industrialization process, the water body is polluted, the water quality problem is frequent, and a plurality of troubles and challenges are brought to the pond aquaculture. The problem of the water quality of the pond aquaculture is solved with great strength, and the economic benefit and the ecological benefit of the pond aquaculture are improved continuously.

The most effective method is that enough dissolved oxygen is added into water, when the value of the dissolved oxygen in the water body is more than or equal to 2mg/L, various aerobic microorganisms in the water can be promoted to eat organic pollutants, the index of COD of the water body is reduced, and the water quality of the water body is improved.

Dissolved oxygen in water exists as oxygen in the atmosphere diffuses into water, which is usually only a part of a ten-thousandth of the air, and mg/L is generally used as the quantification unit. The amount of oxygen molecules dissolved in water is related to the kinetic activity of water molecules. When the water temperature is high, the water molecules have high activity and move violently, the oxygen extruded out of the water surface is relatively more, so when the temperature is increased, the water molecules move and are enhanced along with the increase of the extruded oxygen molecules, and the dissolved oxygen in the water is reduced along with the increase of the temperature, and the water is a dynamic parameter. The relationship between dissolved oxygen values and water temperature can be seen in the following table and figures.
