Embodiment example 1

[0018] River Oxygenation

[0019] The eutrophication of the river will cause the excessive consumption of dissolved oxygen in the water. The whole water body is severely hypoxic, anaerobic process occurs, and a large amount of odor and black sludge are produced, which seriously affects the ecosystem of the river. In order to improve the river system, black sludge should be eliminated. And the generation of odor, it is necessary to oxygenate the river water. Adopting the device of the invention can carry out effective oxygenation, is fast and efficient, and greatly reduces operating costs.

[0020] Use this graded oxygen dissolving device to dissolve oxygen into the water, and then release it into the river. Oxygen adopts industrial filling oxygen. 8kg / cm 2 The high-pressure capacity water flow rate is 2000kg / h, and the dissolved oxygen content is 402mg / L. After 48 hours of oxygenation in the river, the amount of oxygen used is 39.6kg. After comprehensive calculation, the ...

[0022] Oxygenation for fish pond culture

[0023] It is necessary to maintain the dissolved oxygen content of the fish pond in the fish pond, and it is necessary to carry out oxygenation operation on the fish pond from time to time to maintain the dissolved oxygen content of the fish pond. Maintain the system balance of the whole fish pond. By adopting the device of the invention, the dissolved oxygen can be supplemented quickly according to the needs, and the cost of oxygenation can be greatly reduced.

[0024] Use this graded oxygen dissolving device to dissolve oxygen into the water, and then release it into the fish pond. Oxygen adopts industrial filling oxygen. 8kg / cm 2 The high-pressure capacity water flow rate is 1000kg / h, and the dissolved oxygen content is 398mg / L. After 2 hours of oxygenation, the amount of oxygen used is 0.82kg. After comprehensive calculation, the oxygen dissolution efficiency is 97.1%.

[0026] Oxygenation in aerobic biological treatment in sewage treatment

[0027] In the process of aerobic biochemistry in sewage treatment, continuous oxygenation of sewage is required to ensure the normal growth and metabolism of microorganisms in sewage. In the metabolic process, dissolved oxygen, organic matter, trace elements, etc. are used as raw materials for microbial metabolism. Use this graded oxygen dissolving device to dissolve oxygen into water, and then release it into the aerobic biochemical pool. Oxygen adopts industrial filling oxygen. 8kg / cm 2 The high-pressure capacity water flow rate is 100kg / h, and the dissolved oxygen content is 392mg / L. After 48 hours of oxygenation, the amount of oxygen used is 1.95kg. After comprehensive calculation, the oxygen dissolution efficiency is 96.5%.

Description

technical field [0001] The invention relates to a device for dissolving oxygen in water under pressure, in particular to a device and a method for dissolving oxygen in graded pressure water. Background technique [0002] Industrial sewage and biological sewage treatment, and aquaculture water need to fill the water with a large amount of oxygen. The traditional way to increase the oxygen content in the water is to use a blower or a machine to dissolve the oxygen in the air into the water. Due to the influence of nitrogen in the air, the efficiency of the dissolution equipment adopted at the same time is low. Therefore, the utilization rate of oxygen is low. cause severe energy consumption. Therefore, it is necessary to reduce energy consumption through efficient dissolved oxygen devices. Contents of the invention [0003] In view of the existing needs of the prior art, the present invention provides a device for dissolving oxygen in graded pressure water and a method fo...
