Description

Technical Field

[0001] The invention relates to the technical field of phosphorus removal devices, in particular to a phosphorus removal device utilizing cyanobacteria. Background Art

[0002] Phosphorus is one of the main nutrients contributing to eutrophication. Blue-green algae blooms in inland rivers and lakes are becoming increasingly frequent and prolonged, and phosphorus concentrations directly contribute to these blooms. Phosphorus removal methods include physical methods such as artificial stratification, low aeration, and enhanced lake flushing and evacuation, as well as geochemical methods such as the use of alum and iron as flocculants and other products (e.g., sand, gravel, and clay) as "capping" materials. These methods require the addition of significant amounts of material or flocculants to the lake, which is time-consuming and labor-intensive. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing phosphorus removal methods require adding a lot of materials or flocculants to lakes, which is time-consuming and labor-intensive, a phosphorus removal device using cyanobacteria is now provided.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a phosphorus removal device using cyanobacteria, including a main body, a hollow body provided in the main body, a float provided on the main body for floating the main body on the water surface, the hollow body having a first cavity and a groove for storing cyanobacteria that are interconnected, a scraping mechanism provided in the first cavity for scraping the cyanobacteria floating on the water surface into the groove, an inlet provided on the main body for the cyanobacteria floating on the water surface to enter the hollow cavity, a slit provided on the main body below the liquid surface, the slit being connected to the first cavity, and an ultraviolet lamp provided in the first cavity.

[0005] In some preferred embodiments, a cylinder is provided on the main body, the cylinder is communicated with the first cavity, the cylinder is located below the liquid surface, and the slit is provided in the cylinder.

[0006] In some preferred embodiments, the ultraviolet lamp is disposed inside the barrel.

[0007] In some preferred embodiments, a photocatalyst is provided on the inner peripheral wall of the cylinder.

[0008] In some preferred embodiments, the scraping mechanism comprises a conveyor belt rotatably mounted on the body, and a plurality of scrapers are arranged at intervals on the outer surface of the conveyor belt.

[0009] In some preferred embodiments, a screen is provided in the groove, and the screen separates the groove into an upper cavity and a lower cavity.

[0010] In some preferred embodiments, the main body is provided with a solar panel and a battery on the liquid surface, the solar panel and the battery are connected, and the ultraviolet lamp and the scraping mechanism are respectively connected to the battery.

[0011] In some preferred embodiments, a fan is provided on the main body above the liquid level, and the fan is connected to the battery.

[0012] The beneficial effects of the present invention are as follows: when the phosphorus removal device utilizing cyanobacteria is in use, the growth of cyanobacteria is directly promoted by the cyclic irradiation of ultraviolet light, and the purpose of removing phosphorus is achieved by collecting cyanobacteria. No substance or material needs to be added to the lake to complete the removal of phosphorus, and cyanobacterial juveniles can also be removed at the same time. The operation is simple and efficient, and there is no energy consumption or material consumption. Phosphorus and algae can be continuously removed, and cyanobacteria in the lake can be removed in advance to avoid large-scale water algae toxin pollution. The early removal of cyanobacteria can reduce the amount of cyanobacteria. The cyanobacteria can be removed by a scraper when the cyanobacteria just float up, avoiding concentrated removal when the cyanobacteria grow to a very large volume, thereby reducing the amount of treatment.

[0021] like Figure 1-2 As shown, a phosphorus removal device using blue algae includes a rectangular body 1, with several cylinders 9 arranged in the middle below the body 1, the top of the cylinder 9 is connected to the bottom of the body 1, the hollow body 2 of the body 1 is connected to the cylinder 9, the inner wall of the cylinder 9 is provided with multiple ultraviolet lamps 8, and the outer circumference of the cylinder 9 is provided with multiple vertical slits 7 with a width of 2mm to 4mm. A float 3 is provided on the outside of the body 1 to ensure that the body 1 can float, and the water surface in the body 1 is located above the middle of the float 3, and the cylinder 9 is located below the liquid surface. The inner hollow cavity 2 of the body 1 consists of a connected groove 5 and a first cavity 4, and the grooves 5 are provided on both opposite sides of the first cavity 4. A screen 12 is provided in the groove 5 for filtering water. The scraping mechanism includes a conveyor belt 10 arranged on the body 1, and a scraper 11 is provided on the outer surface of the conveyor belt 10 to continuously scrape the blue algae floating on the water surface in the float 3 and scrape the blue algae into the groove 5;

[0022] A photocatalyst such as titanium dioxide is loaded on the inner wall of the cylinder 9, which can photocatalytically degrade organic matter in the water under the irradiation of ultraviolet light.

[0023] A solar panel 13 and a battery 14 are connected to each other on the top of the main body 1 . The battery 14 is connected to the ultraviolet lamp 8 and the conveyor belt 10 . The battery 14 provides power for the ultraviolet lamp 8 and the conveyor belt 10 .

[0024] A fan 15 is provided on both sides of the solar panel 13. Both fans 15 are connected to the battery 14. The two fans 15 face in opposite directions and work in turns to drive the entire device to continue to float slowly on the water.

[0025] When the above-mentioned phosphorus removal device using blue algae is in use, the main body 1 is placed in the lake water body and the buoyancy of the float 3 is used to make the main body 1 float on the water surface. The blue algae on the water surface can enter the cavity body 2 through the inlet 6. Then the conveyor belt 10 is started and it is made to scrape the surface of the water continuously. The ultraviolet lamp 8 is set to start for six hours, then shut down for six hours, and then start for six hours again. This cycle repeats. After forty-eight to seventy-two hours, the blue algae in the irradiated water body will absorb a large amount of phosphorus in the water and grow rapidly. During the growth process, the air sacs of the blue algae become larger, causing them to float into the main body 1. Under the action of the scraper 11 on the conveyor belt 10, the blue algae are collected in the groove 5 and can be removed regularly.

[0026] The electric fan 15 is set to start working after the ultraviolet lamp 8 has completed one cycle of work. As the fan 15 rotates, the body 1 slowly floats on the water surface and removes blue algae in the water by changing its position.

[0027] The ultraviolet light from UV lamp 8 is the key triggering factor for the accumulation of total phosphorus, soluble inorganic phosphorus and polyphosphates in the cells of cyanobacteria in water blooms. As the ultraviolet dose increases, the accumulation of polyphosphates in the cyanobacteria cells can lead to excessive absorption of phosphorus by the cyanobacteria in water blooms, providing sufficient phosphorus for the growth of cyanobacteria in a suitable environment. Ultraviolet light can also promote the increase in the content of phycocyanin, allophycocyanin and phycoerythrin, and produce enough ATP through photosynthesis for cyanobacterial cells in the lake environment to synthesize polyphosphates.

[0028] In order to avoid damage from high-intensity ultraviolet radiation, cyanobacteria accumulate excessive polyphosphates. This accumulation of intracellular phosphorus is beneficial to their growth, causing them to grow and float to obtain more sunlight. Frequent changes in ultraviolet radiation intensity can prompt cyanobacteria to absorb excess phosphorus from suspended solids or sediments.

[0029] The above description of the preferred embodiments of the present invention is intended to serve as a guide. Based on the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
