Description

{Manufacturing apparatus of eco-friendly green algae and red algae remover}

The present invention relates to an eco-friendly green algae and red algae remover manufacturing apparatus and method for manufacturing the same, and to a green algae and red algae remover manufactured thereby. More specifically, it relates to a method of removing green algae and red algae using natural minerals obtained from nature and further improving water quality. It relates to an eco-friendly green algae and red tide remover manufacturing apparatus and method for manufacturing the same, and a green algae and red tide remover manufactured thereby.

In general, green algae refers to a phenomenon in which the color of water turns green due to the large growth of phytoplankton such as cyanobacteria. It is mainly caused by the large growth of cyanobacteria, which can form colonies and become thick like paint. A similar phenomenon in the ocean is a red tide caused by dinoflagellate algae.

The causes of these green algae include increased emissions of nutrients (nitrogen and phosphorus) due to global population growth and industrialization, increased carbon dioxide concentration in the atmosphere, increased water temperature due to global warming, and stagnant water circulation. It is caused by eutrophication of water bodies, especially excessive inflow of phosphorus, and when phosphorus is introduced in the presence of nitrogen from fertilizers sprayed on surrounding agricultural lands, etc., specific cyanobacteria or algae grow.

If an environment suitable for the growth of a specific species continues, the number of algae or cyanobacteria cells increases explosively as a result of cell division, changing the color of the water. In the case of cyanobacteria, a representative green algae-causing organism, a specific cyanobacterial species must already exist in the water body. It is known that mass outbreaks occur only when all conditions are met: buoyancy has a positive value and turbulent mixing of water is too weak to prevent the movement of cells trying to float upward.

Blue-green algae, which have the ability to float, easily form highly concentrated toxic scum when they multiply in large quantities, and when they accumulate on riversides or lakeshores, they can maintain thick mat-like scum for hours to weeks. Scum, which looks like loose paint or jelly, is not aesthetically pleasing, but because it has concentrated toxicity, it is very dangerous because it can cause symptoms such as gastrointestinal disorders, liver cirrhosis, kidney failure, and dehydration when exposed to humans.

Most algae that cause green algae produce a foul odor (such as a moldy odor), which causes discomfort to citizens who use tap water for domestic purposes. Moreover, since these organic compounds that cause unpleasant tastes are soluble, they cannot be treated with simple filtration technology and require an advanced treatment process, which is very expensive.

In addition, green algae has negative effects on the water purification process, such as filtration and coagulation difficulties and the creation of disinfection by-products, and as a result, the quality of tap water can also deteriorate. Therefore, green algae is a major threat to public health not only domestically but also around the world. .

In particular, cyanobacteria produce hepatotoxins such as microcystin and neurotoxins such as anatoxin-a, and cases of mass death of livestock and wild animals have been reported in foreign countries.

Methods for treating such green algae include chemical technology that separates coagulation and sedimentation by chemicals such as coagulants or kills algae by adding ozone or oxidizing agents, biological technology that kills algae by living organisms, and microbubbles in water. There are physical techniques such as injecting algae to float them and then removing them, or using ultrasonic vibration to suppress the growth of algae.

The red tide phenomenon occurs when plankton proliferates in large quantities when putrefactive organic pollutants, trace metals, and growth-promoting substances are abundantly dissolved, and when environmental conditions such as solar radiation, water temperature, and salinity are appropriate. In particular, when accumulated by wind or currents, the red tide phenomenon occurs at high densities. Red tide occurs. In particular, it occurs habitually in closed bays or coastal areas where a large amount of domestic sewage flows in and nutrients deposited in the bottom are leached out.

The biggest factor causing red tide is, like green algae, eutrophication of the water, that is, when there are too many organic nutrients in the water, when the water temperature rises due to changes in air temperature, causing microorganisms to reproduce more actively, and when there is less wind, making the sea water more turbulent. It is known that red tide occurs even when they are not mixed.

In particular, it is known that red tides appear more frequently due to rising water temperatures due to global environmental changes such as the recent El Niño phenomenon. When green or red tides occur, the concentration of dissolved oxygen in the water decreases, so fish and shellfish that breathe using oxygen in the water What they have in common is that many deaths due to suffocation occur.

In addition, there are cases where plankton gets caught in the gills of fish and causes physical suffocation, and some of the plankton that cause green or red tides contain toxic algae, which can cause death due to ototoxicity.

Recently, a common method of controlling red tide and green tide is to use the property of red clay colloidal particles to coagulate and adhere suspended substances (nutrients, microplankton, etc.) in seawater to coagulate and precipitate red tide organisms in red clay when red tide occurs. However, when red clay is sprayed into seawater, suspended solids temporarily increase, which has the disadvantage of affecting living organisms such as respiratory problems due to closure of fish gills in fish farms and fishing grounds where sessile organisms live in the bottom.

In addition, there is a problem in that red clay spray causes physiological disorders or death of marine organisms as red clay particles and red tide combine and settle to the bottom of the sea, forming mucilage composed of red clay particles and acidifying the low-quality soil.

Figure 2 is a combined perspective view showing a preferred embodiment of the present invention.
3 to 5 are inspection reports

Hereinafter, the eco-friendly green algae and red tide remover manufacturing apparatus and manufacturing method thereof proposed by the present invention and the green algae and red tide remover manufactured thereby will be described according to the attached drawings and preferred embodiments.

First, the production device S for an eco-friendly green algae and red algae remover is equipped with a raw water tank 10 filled with raw water, as shown in FIGS. 1 and 2.

The raw water tank may have a circular or polygonal shape, and an inlet pipe 20 for incoming raw water is installed at the top, and at the same time, an electromagnetic valve 21 for regulating or controlling the amount of incoming water is installed on one side of the inlet pipe 20. It is installed.

At the bottom of the raw water tank 10, a water discharge pipe 30 for removing water is installed, through which the manufactured remover is discharged. The inside of the raw water tank 10 is filled with natural minerals and a raw water conversion device provided in a network structure. (40) is installed to facilitate deposit and withdrawal.

On one side of the water outlet pipe 30, a silver-added activated carbon filter 31 is installed to filter out heavy metals that may be contained in the discharged water remover, thereby preventing water pollution due to heavy metals in advance.

The natural minerals 44 are used in the amount of 30 to 40 parts by weight of elvan, 15 to 25 zeolites, and 5 to 10 parts by weight of feldspar, each of which has a diameter of 1 to 5 mm. Inside the raw water tank 10, there is a raw water diverter 40. ) A fixing groove 11 of a symmetrical structure is formed so that it can be fixed upright inside the raw water tank.

Among the natural minerals, zeolite (Si, Al) is a microporous aluminum silicate component and is reported to be effective in removing green algae, red algae, and turbidity.

In particular, zeolite has an excellent ability to adsorb nitrogen oxides (NOx), and during the adsorption process, oxidation and reduction reactions occur simultaneously and hydrogen peroxide (H₂O₂) is generated during the reaction process, but the hydrogen peroxide generated at this time is reduced to an unstable state and generates oxygen. The amount of dissolved oxygen in the water increases and the growth of suspended substances such as green algae is suppressed.

also, Elvan stone is a rock component belonging to porphyry and is reported to be effective in removing green algae and turbidity. It has ion exchange action, removal of harmful substances and decomposition of heavy metals, and adjusts pH and water purification to make water slightly alkaline, improving the softness and hardness of water. It is adjusted, maintains abundant oxygen content, reduces BOD and COD, and increases dissolved oxygen.

In addition, feldspar is an aluminum layered silicate mineral containing potassium, sodium, and calcium and is effective in removing arsenic and cenium. As a result of the adsorption test, 99, 98, and 97% of Pb, Cu, and Fe were respectively adsorbed within 1 hour of reaction. It is used as a heavy metal adsorbent for water purification.

In addition, the raw water diverter 40 is provided with a square frame 41, and the front and rear sides of the frame 41 are composed of a mesh 43-shaped structure to facilitate the passage of raw water, and a moving handle is provided at the top. (42) is installed.

In addition, a circulation pump 50 is installed inside or outside the raw water tank 10 to circulate the raw water filled inside the raw water tank 10 while operating according to the operation control of the controller 60, and the circulation pump 50 is installed inside or outside the raw water tank 10. The pump 50 not only circulates the raw water inside the raw water tank, but also performs the function of cleaning various foreign substances that may be inside the raw water diverter 40 when it rotates at high pressure.

A numerical input unit 61 that controls the operation of the solenoid valve 21 and the circulation pump 50 and inputs the raw water acquisition date, and a warning sound to the manager when a malfunction of the solenoid valve 21 and the circulation pump 50 occurs. A warning alarm unit 62 that generates the product or displays it with an LED and a completion display unit 63 that indicates the completion of manufacturing 24 to 30 hours after confirming the date of acquisition are installed, and all operations are controlled to stop as soon as the manufacturing completion is indicated. A controller 60 is configured.

And the method of manufacturing an eco-friendly green algae and red tide remover is to prepare a raw water converter (40) filled with 30 to 40 parts by weight of elvan, 15 to 25 zeolites, and 5 to 10 parts by weight of feldspar, each having a diameter of 1 to 5 mm, and then with 0.5 to 1 L of hydrogen peroxide. It is placed inside the raw water tank (10) filled with 100L of raw water and then immersed for 24 to 30 hours. During the immersion process, the inside of the raw water tank is circulated 5 to 10 times for 10 to 20 minutes per circulation. However, the production of green algae and red algae remover is completed by circulating the raw water through the raw water converter.

The raw water conversion body 40 filled with the natural minerals can be used semi-permanently, significantly reducing the cost of manufacturing the remover, and converts the raw water into a remover that removes green or red algae.

The green algae and red algae remover manufactured as described above can prevent water pollution caused by heavy metals in advance because heavy metals are filtered during the water extraction process. When dozens of raw water tanks (10) are placed and managed, continuous production of the remover is possible. This is possible, and this can also be installed to facilitate integrated control through the controller 60.

When used, it can be seen in Figures 3 to 5 that if the spray is applied to a site where green or red tide has occurred, not only the green or red tide is removed, but the water quality is also improved.

Meanwhile, the following examples are only for illustrating the present invention, and are not limited by the following examples, and substitutions and other equivalent examples may be made without departing from the technical spirit of the present invention. It will be clear to those skilled in the art to which the invention pertains.

Hereinafter, the present invention will be described in more detail based on the following examples.

After filling the inside of the raw water tank 10 with 100 L of raw water, 35 kg of elvan with a diameter of 1 to 5 mm, 20 kg of zeolite with a diameter of 1 to 5 mm, and 5 kg of feldspar with a diameter of 1 to 5 mm are filled into the raw water converter 40. 0.8L of hydrogen peroxide was added together.

After injection, the circulation pump was operated to circulate the raw water for 10 minutes every 3 hours, and then a remover was prepared that was filtered through an activated carbon filter.

When the remover prepared as described above was treated with contaminated water containing green algae, as can be seen in FIGS. 3 to 5, green algae were removed and the water quality was improved to a level that could be consumed by humans.
