Aeration system based on micro-nano bubbles

Abstract

The invention discloses an aeration system based on micro-nano bubbles. The system comprises a micro-nano bubble generating device, a water quality monitoring system, an intelligent control system anda gas source conveying system, wherein the water quality monitoring system comprises a dissolved oxygen sensor, the intelligent control system comprises a central processor, and the gas source conveying system comprises an oxygen generator; the signal output end of the dissolved oxygen sensor is connected to the signal input end of the central processor, the first signal output end of the centralprocessor is connected with the signal input end of the micro-nano bubble generating device, and the second signal output end of the central processor is connected to the signal input end of the oxygen generator; and a water gate dispatching system is further included, and the third signal output end of the central processor is connected to the signal input end of a water gate control motor. Through the aeration system, intelligent monitor and supplement of dissolved oxygen in the water body can be achieved, and the aeration system 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 device, in particular to an oxygenation system 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
