Aerating device and water body activating method

Abstract

The invention discloses an aerating and stirring device which can be applied to the field of cultivation and environmental protection and can improve the water quality and a water body activating method. An aerating device activates water body by adopting stirring and aerating modes, wherein a stirring device and the aerating device can operate respectively or simultaneously, an optimal working mode is selected according to actual requirements, and submersible-type vanes in the stirring device can guide pool water into water surface from the water bottom so as to form circulating water flow; and the aerating device improves the oxygen content in water and takes harmful gases away from the water by conveying tiny air bubbles into the water body, promotes the ecological self-purification of water and has the advantages of energy saving and low noise.

Description

technical field [0001] The invention relates to an aeration device with aeration and stirring functions for water bodies and a water body activation method thereof, in particular to an aeration stirring machine and a water body activation method which can be applied to the fields of aquaculture and environmental protection to improve water quality. Background technique [0002] At present, there are two aeration methods used to improve water quality in the fields of aquaculture and environmental protection. One is to aerate the entire water area by arranging an aeration pipe network at the bottom of the water body and blowing air through a fan. The disadvantage of this method is that the air pressure varies with the distance from the air source, and the aeration is uneven, resulting in almost no air supply in some water areas. In addition, the unit area investment of this method is relatively large, and at the same time, the underwater topography is complex and difficult. In...

Problems solved by technology

Aerated aeration and microporous aeration can increase the amount of oxygen at the bottom of the water and increase the amount of dissolved oxygen in the water, but the water body with aerated aeration and microporous aeration is in a static state and cannot achieve high dissolved oxygen. Rapid exchange and convection of water body, especially in high temperature state in summer, the surface temperature of the fish pond is high, and the temperature of the bottom part is low, but between 4°C and 100°C, the density of water decreases with the increase of temperature, and the density of the lower part of the fish pond High, low density in the upper part, unable to produce convection of the water body, resulting in poor activity of the lower water body due to lack of convection and sunlight, and harmful bacteria multiply quickly, which is not conducive to the survival of fish and shrimp

[0003] These two "mechanical point oxygenation" methods have uneven water quality improvement effects in the overall water area

At present, the aquaculture industry is calculated according to the aquaculture area, so most farmers will deepen the aquaculture depth of the water area, and the aerators currently used are generally only plowing water on the water surface, the effective depth of vertical circulating water flow is limited, and the oxygen exchange of the bottom water body , The effect of oxygenation is very poor, and the problem of water body corruption and odor is more serious
