[0002] At present, the main technical means to improve river water quality include biological restoration, physical and chemical restoration, ecological engineering restoration, etc. Among them, biological restoration technology uses the metabolism of microorganisms, aquatic plants, aquatic animals and other organisms to degrade, absorb and transform organic matter, nitrogen and phosphorus and other pollutants in the water, thereby increasing the dissolved oxygen content of the water, reducing the pollution load of the water, improving the black and smelly condition of the water, and restoring the self-purification capacity of the water. Biological restoration technology has the advantages of low cost, good effect and no secondary pollution, and has been widely used in engineering practices to improve river water quality.

[0003] However, the implementation of bioremediation technology also faces some problems and challenges, such as insufficient dissolved oxygen content in water, which limits the metabolic activity of organisms and reduces the efficiency of restoration; excessive content of organic matter, nitrogen, phosphorus and other pollutants in water, which exceeds the processing capacity of organisms, causing inhibition or death of organisms; poor fluidity of water bodies, resulting in uneven distribution of pollutants in water bodies and unstable water quality, etc. Therefore, how to increase the dissolved oxygen content in water bodies, enhance the fluidity of water bodies, and improve the uniformity of pollutant distribution in water bodies is the key to improving the effect of bioremediation technology.

[0004] In order to solve the above problems, there are some oxygen supply equipment used to improve the water quality of rivers, such as push flow aerator, jet aerator, water jet aerator, impeller aerator, waterwheel aerator, blower aerator, etc. These equipment mainly transport air or pure oxygen into the water body by mechanical or pneumatic means, so as to increase the dissolved oxygen content in the water body, and at the same time generate a certain water flow, increase the fluidity of the water body, and promote the uniform distribution of pollutants in the water body. The advantages of these equipment are high oxygenation efficiency, simple operation and convenient maintenance, but there are also some disadvantages, such as high energy consumption, high noise, excessive turbulence of the water body, which may affect the survival of aquatic organisms, and the equipment has a short life and is easy to damage. Therefore, there is an urgent need for an oxygen supply equipment that can overcome the above disadvantages, can efficiently, safely and stably provide sufficient dissolved oxygen for river water quality, enhance the fluidity of the water body, and improve the uniformity of pollutant distribution in the water body.

One end of each swing rod is fixedly connected to one end of a long rod, and one end of a group of evenly arranged fan blades is fixed on each long rod, and the fan blades correspond to the through grooves one by one.
