Aeration method based on micro-nano bubbles

Abstract

The invention discloses an aeration method based on micro-nano bubbles. The aeration method comprises the steps of: (1) first collection of oxygen content; (2) first comparison of the oxygen content;(3) introduction of the micro-nano bubbles: when the first signal value of the oxygen content is less than a preset value of the oxygen content, introducing the micro-nano bubbles in a water body, andstopping introduction of the micro-nano bubbles after the introduction time reaches the preset time; (4) second collection of the oxygen content; (5) second comparison of the oxygen content; (6) introduction of oxygen: introducing oxygen into the water body when the second signal value of the oxygen content is less than the preset value of the oxygen content, then collecting the oxygen content once at set intervals, comparing the collected signal value of the oxygen content with the preset value of the oxygen content until the requirement that the collected signal value of the oxygen contentis greater than or equal to the preset value of the oxygen content is met, and stopping introduction of oxygen. Through the aeration method, intelligent monitor and supplement of dissolved oxygen in the water body can be achieved, and the aeration method has the characteristics of high oxygen dissolution efficiency, high work efficiency and low operation cost.

Description

technical field [0001] The invention relates to a water body oxygenation method, in particular to an oxygenation method based on micro-nano bubbles. Background technique [0002] Dissolved oxygen is an important water quality indicator in water bodies, and insufficient dissolved oxygen is the root cause of black and odorous water bodies. At present, some water bodies in my country receive excessive pollutants, far exceeding their thresholds. It is difficult to meet the self-purification needs of water bodies through natural aeration. Both domestic and foreign engineering test research and actual results have proved that artificial aeration of rivers can effectively improve the water body's ability to degrade pollutants, improve the flow of water bodies and energy, improve the self-purification ability of water bodies, and contribute to the development of river ecosystems. Restoration and reconstruction is a river black and odor control technology with low investment, less la...

Problems solved by technology

This type of device will introduce a large amount of gas into the cavity of the centrifugal pump, forming cavitation, thereby reducing the working efficiency of the pump. In severe cases, the pump will run idly, which greatly reduces the service life of the pump. The working condition is unstable, and it is impossible to intelligently monitor and supplement the dissolved oxygen in the water body
