The oxygen increasing effect in the prior art is better by adopting oxygen enrichment to carry out water body oxygen increasing treatment, the current oxygen enrichment dissolved oxygen equipment generally adopts an aeration pipe or an aeration head with smaller micropore diameter, and the oxygen partial pressure in the oxygen enrichment equipment is greater than the oxygen partial pressure in the atmosphere, so the dissolved oxygen amount can be increased by 3-5 times. However, the influence range of the aeration head or the aeration pipe on the water body in the static water is limited, the water body circulating device is optimally matched with the oxygen-enriched aeration head to be used simultaneously, the dissolved oxygen amount of the circulating water body can reach about 20mg/L of an upper limit value, but when the large water body is treated, the influence on the large water body when the circulating water body after oxygenation converges into the large water body is still limited, and the regional distribution of the oxygen concentration is uneven.

The problem can be effectively solved by a high-pressure oxygen-enriched oxygen dissolving mode, and the maximum amount of oxygen dissolved in water is called as oxygen saturation concentration under certain temperature and pressure conditions. According to the expression henry's law, P (oxygen) is the partial pressure of oxygen over water, K is the henry coefficient related to temperature, and X (oxygen) is the mole fraction of oxygen in water. Therefore, when the system is in a positive pressure (0-3barg) oxygen-enriched environment, compared with the atmospheric environment, the P (oxygen) is improved by 4-15 times, and the oxygen saturation concentration of the water body can be greatly improved by matching with an effective oxygen dissolving device, the oxygen solubility can reach 20-80 mg/L, and the stable reliability of the oxygenation water treatment is very effective by matching with the internal circulation design.

The positive pressure oxygen-enriched oxygen dissolving water treatment tower can realize the positive pressure oxygen-enriched dissolving process, the reasonable structural design can realize that the oxygen dissolving rate is close to 100 percent, and the low-cost high-efficiency oxygenation circulation is realized.
