Problems solved by technology

But both of them use microporous aeration technology, because the violent agitation of the oxygen-increasing bubbles or the violent water flow when falling into the water is not conducive to the construction of the ecosystem, so currently only low-power aeration can be used
In addition, due to the limitation of power equipment, these technologies are theoretically difficult to be extended to the purification of large water bodies.

Embodiment 1

[0037] The physical lung-type aerobic reef of this embodiment adopts dense glass fiber satin cloth, sprays a small amount of beeswax emulsion on the back to plug the holes and dries to make an airbag of about 0.1 cubic meters, so that the outer layer of the airbag is hydrophilic The layer is relatively hydrophobic and the large voids are basically blocked, so the airbag made in this way has no visible air leakage in water and can be wetted by water. Adhering and anchoring a large number of loose non-woven fabrics and short ropes on the surface of the airbag, first impregnating the potassium phosphate / bentonite mixture, then continuing to impregnate the mixed solution of magnesium chloride and ferric chloride to form a thin layer of medium, and then impregnating the kneaded filamentous Algae slurry inoculation.

[0038] The airbag is connected to a connecting pipe with a one-way valve, which is a hose with a bicycle tire air valve leading directly to the water surface. The lowe...

Embodiment 2

[0044] In this embodiment, in a 200-liter open-air plastic water tank, 150 liters of inferior Class 5 water (black and odorous water quality, recorded dissolved oxygen is 0 mg / l) is loaded into 150 liters of water, and an anaerobic water tank with a thickness of about 5 centimeters is laid at the bottom of the bucket simultaneously. Bottom mud (black, with strong odor), the water surface of the water tank is closed with a transparent plastic film to maintain the anoxic state of the water body.

[0045] Use 2 dense glass fiber satin cloth (of course, you can also use a bottom-cut mineral water bucket when the performance is not very good), spray a small amount of silane coupling agent on the back of the airbag, and dry each airbag The volume is 10 liters, the airbag is connected to a connecting pipe with a one-way valve, that is, the hose with the bicycle tire valve goes straight to the water surface and passes through the plastic film. The airbag is directly fixed in the plasti...

Abstract

The invention discloses a physical lung-type oxygenation organic reef and its application method, wherein the physical lung-type oxygenation organic reef is fixed in water body. The invention is characterized in that the physical lung-type oxygenation organic reef is made from a high-strength thin film material; a large opening air bag is fixed underwater with the opening of the air bag downward and the bottom of the air bag keeps a certain distance from the water-bed; the top of the air bag is equipped with a connecting pipe, which leads directly to the water surface and is provided with a one-way check valve, and simultaneously the outer wall of the air bag is connected with a lot of hydrophilic fibers or ropes; a gas which is filled into the connecting pipe is reserved inside the upper portion of the air bag and directly contacts with the water surface under the lower portion of the air bag to form the physical lung-type oxygenation organic reef.

Description

technical field [0001] The invention relates to a physical lung type oxygen-increasing biological reef and its application method. Background technique [0002] Usually the saturated dissolved oxygen in the water body is around 10mg / l. When the dissolved oxygen in the water body is lower than 4mg / l, it will affect the survival of most fish and shrimps, aquatic plants and aerobic colonies. It is generally believed that 20% of natural dissolved oxygen comes from water surface air contact, and 80% comes from photosynthetic oxygen production of water algae and large plants. [0003] Generally, the water surface and the upper water body with good light transmittance will not lack oxygen due to the oxygenation of wind waves and the photosynthetic oxygen production of aquatic plants. In the deep water area of ​​the water body (usually there is basically no light penetration, and the biomass is large), due to insufficient oxygen production by plants and lack of supplementation of d...
