Embodiment 1

[0043] like Figure 1-5 As shown, an algal bloom suppressing device includes a shading part 1 that reduces the transmittance of light of a specific wavelength, a gas barrier part 2 that reduces the gas exchange rate, a semi-permeable part 3 that allows inorganic or organic molecules of a certain size to penetrate, The turbulence part 4 that promotes the mixing of gas and liquid, the open space 5 and the exchange interface 6 that allows gas and liquid to enter and exit, the open space 5 is surrounded by the above-mentioned light shielding part 1 , gas barrier part 2 and semi-permeable part 3 .

[0044] In this embodiment, the light-shielding part 1 , the air barrier part 2 , the semi-permeable part 3 and the spoiler part 4 are components with independent functions, and are mainly made of polymer materials such as polypropylene and polycarbonate.

[0045] The open space 5 initially accommodates a certain volume of water of the target water body, and this part of the water has be...

Embodiment 2

[0056] like Figure 9-12 As shown, an algal bloom suppressing device includes a shading part 1 that reduces the transmittance of light of a specific wavelength, a gas barrier part 2 that reduces the gas exchange rate, a semi-permeable part 3 that allows inorganic or organic molecules of a certain size to penetrate, and promotes The turbulence part 4 for gas and liquid mixing, the open space 5 and the exchange interface 6 for allowing gas and liquid to enter and exit, the open space is surrounded by the above-mentioned light shielding part 1 , gas barrier part 2 and semi-permeable part 3 . The device is manufactured by laminating two upper and lower units with exactly the same size. Except for the different optical properties of the light-shielding part, the materials of other parts of the upper and lower units are correspondingly the same.

[0057] In this embodiment, the light-shielding part 1 , the air barrier part 2 , the semi-permeable part 3 and the spoiler part 4 have in...

Abstract

The invention relates to an algal bloom inhibiting device, belonging to the technical field of ecological restoration of water bodies. The algal bloom inhibiting device comprises a shading part for interfering the transmittance of light with specific wavelength, a gas isolation part for reducing a gas exchange rate, a semi-permeable part for allowing inorganic or organic molecules with a certain size to pass through, a turbulence part for promoting gas-liquid mixing, an open space and an exchange interface for allowing gas and liquid to enter and exit, wherein the open space is defined by theshading part, the gas isolation part and the semi-permeable part. The algal bloom inhibiting device can intervene in the transmissivity of light with a specific wavelength range on the surface of a water body, reduce the gas exchange rate of the surface layer of the water body, and guide light energy originally flowing to harmful algal blooms and carbon dioxide to beneficial algae in the device, thereby inhibit the growth of the algal bloom. According to the invention, ecological niche replacement of the algal bloom can be realized, the starting time of algal bloom control is greatly advanced,and meanwhile, the treatment cost and ecological risks of the algal bloom are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of water body ecological restoration and relates to an algal bloom suppression device. Background technique [0002] The rapid development of human society is accelerating the eutrophication of water bodies adjacent to human society. Driven by the aggravation of water eutrophication and climate warming, algal blooms have occurred frequently around the world in recent years, and the economic losses caused by algal blooms have continued to increase. Algal blooms refer to the phenomenon of ecological imbalance caused by the excessive reproduction of photosynthetic autotrophic microorganisms such as cyanobacteria. Its hazards are manifested in many aspects: first, some types of algal blooms release algal toxins, which threaten the safety of drinking water sources; second, once algal toxins are produced, they will accumulate in the food chain, causing food safety hazards; Strong fishy smell, when the algae bloo...
