Description

Technical Field

[0001] The invention belongs to the field of water aeration, and in particular relates to a surface water deep aeration device and an aeration method driven by multiple power forms. Background Art

[0002] It is difficult to exchange water between the upper and lower parts of a river or lake, especially when the water depth exceeds 3m. It is difficult for a river without flow to exchange water between the upper and lower parts, which results in poor self-purification ability and water quality of deep water bodies. This is also a problem that plagues water pollution control in rivers or lakes. The lower water has a low temperature and high water density, while the upper water has a high temperature and low water density, making it impossible to achieve natural water exchange. Artificial regulation to achieve water exchange has become the focus of research; the current external power mechanical pumping and aeration method consumes a lot of electricity and is costly. The use of chemical flocculants to treat deep water bodies is not only costly, but also has negative effects on the environment; therefore, reducing costs and improving the water's own purification ability have become the focus of river pollution control research.

[0003] Existing aeration schemes mainly achieve deep aeration in the form of air oxygenation aeration. Since it takes a certain amount of time for the oxygen in the air to dissolve into the water body, the air aeration oxygenation efficiency is low. In addition, under the action of high water pressure, it is difficult to inject air into deep water bodies, and more kinetic energy is required to achieve it. The deep water injection method requires overcoming a certain water pressure to achieve it, which consumes a lot of energy.

[0004] Most of the current wind-powered aeration devices are for shallow water treatment, and their operating efficiency is generally low, so it is difficult to promote and apply them. The existing wind-powered aeration devices cannot be used for aeration of deep water bodies due to the aeration form. Electric power aeration is efficient, but it has the disadvantages of high cost and poor effect. Therefore, it is of great significance to develop a low-cost, high-efficiency, multi-power-driven deep aeration device and aeration method for surface water bodies. Summary of the invention
