[0001] APPARATUS OF REMOVING GREEN ALGAE AND IMPROVING THE QUALITY OF WATER [0002]

The present invention relates to an apparatus capable of removing algae and improving water quality using a ceramic ball and an aeration apparatus.

More particularly, the present invention relates to a method for removing algae that can remove algae while improving water quality by increasing the contact area by maximizing the contact area by sedimenting a mesh containing the ceramic balls manufactured in a ball shape, And a water quality improving apparatus.

In addition, an aeration device is provided to supply water into the water, thereby increasing the dissolved oxygen amount (DO) and allowing the water to circulate so that the air supplied to the water floats and the surface water floats up to the surface layer. And to an algae elimination and water quality improvement device capable of eliminating algae.

In addition, as the air supplied to the water from the aeration device floats, the contact rate of the ceramic balls, air and algae is increased by increasing the fluidity of the ceramic balls accommodated in the mesh, thereby improving the water quality and algae removal and water quality And an improvement device.

In general, when nutrients such as organic matter, nitrogen (N, Netrogen), phosphorus (Phosphorus), etc.) are supplied to reservoir, lake, river and sea excessively and eutrophication occurs, phytoplankton or algae Algae, algae) are propagated in large quantities at a time, causing red tide or green tide phenomenon that causes the area to turn red or yellow green.

These eutrophication is known to occur when nutrients are accumulated in the sea, rivers and lakes (swamps, lakes, reservoirs, dams) in the breeding of algae such as nitrogen (N) and phosphorus (P). If nutrients are adequately present, they are purified by dilution, sedimentation, and biodegradation. However, when these nutrients are supplied at once, and the self-purification ability is lost, various algae will breed, This is a vicious cycle of becoming.

The red tide or green tide phenomenon caused by eutrophication is not only deteriorated in transparency due to color change but also damages the surrounding landscape. In addition, poisonous substances are generated in the water and aquatic organisms are killed, and debris from the death of the propagated alga And the water quality deteriorates due to the generation of toxic substances and odors. In particular, when a green algae phenomenon appears in a water source, it becomes difficult to treat the water and smells of tap water.

Accordingly, a technique for removing algae through chemical treatment has been developed.

However, the technology through chemical treatment removes algae by injecting chlorine or chemical in the water. In this case, the injected drug is not only effective for algae removal but also adversely affects aquatic organisms. There is a problem in that it can cause the contaminants of the tea.

At this time, the light emitting unit can be configured with an LED having excellent durability by emitting relatively strong light while consuming less power.

The net 200 is installed on the bottom surface of the buoyant body 100 and is configured to have a net-like net structure so that water can flow in or out.

The ceramic ball 300 is accommodated in the mesh 200.

On the other hand, the applicant of the present invention has been granted the patentability of ceramic balls in Registration No. 10-1308070.

The ceramic balls described in the above publication will be described as follows.

The ceramic ball 300 is accommodated in the mesh 200 and is formed into a ball shape and can be manufactured by firing at a temperature of 600 ° C to 800 ° C.

Other components include yttrium (Y), gadolinium (Gd) and lanthanum (La), which are rare earth minerals (rare metals), such as titanium (Ti), selenium (Se), germanium Based mineral elements.

Anhydrous silicic acid (SiO ₂ ) and aluminum oxide (Al ₂ O ₃ ) are the main components of the elvan, and are 300-600 mesh particles that are porous and biocompatible. It also emits minerals, ion exchange, and far infrared rays to prevent and treat various diseases of the organism, and adsorbs and decomposes harmful substances and heavy metals by strong adsorption action, thereby eliminating the cause of spoilage.

Calcium oxide (CaO) is an inexpensive natural minerals and can be mass-produced. It is a particle of 300 ~ 500 mesh and it is an essential element of biochemical balance. It has anti-bacterial coating effect by negative ions and minerals, It is used to remove germs, fungi, bacteria and causative bacteria of food poisoning by alkaline cleaning force generated when it comes into contact with water, and effectively sterilize various corrupt groups, disease bacteria and viruses by the effect of strong sterilization and disinfection.

Tourmaline is a 300-500 mesh particle that is superconducting to attract dust when heated and also called tourmaline.

When tourmaline is contacted with water, the water component is changed into weak alkaline water, so that foreign matter and odor are reduced, and the adsorption action and decomposition action are excellent, so that the water quality is purified and algae and red tide are removed.

Other components are mineral sources for bio-active purposes, such as titanium (Ti), selenium (Se), germanium (Ge) and manganese (Mn), rare earth minerals (rare metals) , Gadolinium (Gd) and lanthanum (La) can be used.

Yttrium (Y), gadolinium (Gd), and lanthanum (La), which are rare earth minerals, are 300 to 500 mesh particles in active promoting type.

The ceramic balls 300 are made of a ball type by mixing materials composed of the above composition and firing at 600 ° C to 800 ° C. The ceramic ball 300 thus manufactured is accommodated in the mesh 200 in the form of a particle and is formed in a ball shape so that a sufficient air gap is formed between the ceramic balls 300. As a result, 300, the water quality is improved by the characteristics of the composition of each particle, and alien substances such as algae are removed.

In addition, the ceramic ball 300 accommodated in the mesh 200 can be used semi-permanently since the external shape does not change even if it is submerged in water, thereby minimizing the need to replace the ceramic ball 300.

When the ceramic ball 300 comes into contact with the contaminated water, it removes eutrophication materials including nitrogen and phosphorus which induce generation of heavy metals, volatile organic compounds, and algae contained in the polluted water, Photocatalytic action photocracking improves the quality of the water by eliminating algae as well as improving water quality.

The air supply unit 420, the branch pipe 430, and the nozzle pipe 440. The air supply unit 410 includes the air supply unit 410, the air supply pipe 420, the branch pipe 430, and the nozzle pipe 440, .

The air supply module 410 is provided in the buoyant body 100 to suck air and supply the air at a predetermined pressure. The air supply module 410 may be a blower or the like.

The air supply module 410 may be installed outside or inside the buoyancy body 100. However, when installed outside, there is a possibility of an error or damage due to external influences (wind, wave).

Accordingly, the air supply module 410 may be installed inside the buoyant body 100 in a case shape.

The air supply pipe 420 is connected to the air supply module 410 and is provided below the buoyant body 100.

The air supply pipe 420 functions to transfer the air generated in the air supply module 410 to the branch pipe 430.

Depending on the design conditions, the air supply pipe 420 may be configured to have an appropriate length depending on the water depth, and the length of the air supply pipe 420 may be variable.

The mesh 200 provided on the bottom surface of the buoyant body 100 has a structure in which the ceramic ball 300 does not flow out of the mesh 200 so that the ceramic ball 300 accommodated in the mesh 200 can be positioned within a certain range. ≪ / RTI >

2 to 3, the mesh 200 is provided to surround the outer surface of the air supply pipe 420, and the upper and lower portions of the mesh 200 are connected to the upper portion of the air supply pipe 420 Respectively, and may have a cross section formed in an elliptical shape.

The branch pipe 430 is connected to the tip of the air supply pipe 420 to disperse the air transferred through the air supply pipe 420, and the nozzle pipe 440 is coupled to each branch.

The nozzle tube 440 is connected to the branch pipe 430 so that air is supplied to the water through the air nozzle 441.

The air generated in the air supply module 410 is transferred to the branch pipe 430 through the air supply pipe 420 and the air transferred to the branch pipe 430 is divided into a plurality of nozzle pipes 440 to be transferred And is supplied to the water through an air nozzle 441 provided in the nozzle tube 440.

Accordingly, the dissolved oxygen amount DO is increased by the air discharged from the air nozzle 441, so that the water quality is purified and algae are removed.

At this time, the air supply module 410, the air supply pipe 420, the branch pipe 430, and the nozzle pipe 430 may be made of stainless steel or the like so as not to rust in water.

Dissolved oxygen (DO) means the molecular oxygen dissolved in water. At this time, if the dissolved oxygen (DO) in the water is insufficient, it will not only cause the death of the fish and shellfish, but also cause the organic matter to remain, .

That is, when DO is insufficient in water, aquatic organisms die, and more oxygen is needed to decompose the bodies of aquatic organisms, thereby worsening water pollution. Therefore, contaminated water presents a problem such as a green algae phenomenon and a bad odor.

Conversely, an increase in dissolved oxygen (DO) provides a living environment for aquatic organisms, and also improves the environment where microorganisms can degrade pollutants, thereby purifying the water.

Therefore, in the present invention, the aeration device 400 is provided to supply air into the water, thereby increasing the dissolved oxygen amount DO in the water to purify the water quality.

In addition, the air supplied to the water from the aeration device 400 floats to float the surface water layer to the surface layer, thereby circulating the water, and the temperature of the surface layer is reduced, thereby suppressing the generation of algae.

In addition, as the air supplied to the water from the aeration device floats, the flowability of the ceramic balls accommodated in the mesh increases, thereby increasing the contact ratio between the ceramic balls, air and algae, thereby improving water quality and algae removal efficiency.

4 is a perspective view of an algae elimination and water quality improvement apparatus according to another embodiment of the present invention.

It should be noted that the overlapping portions of the contents already described in Figs. 2 to 3 are not described.

4, the apparatus for removing algae and improving water quality according to another embodiment of the present invention includes a buoyant body 100, a mesh 200, a ceramic ball 300, an aerator 400, and a solar module 500 ).

The air supply unit 420, the branch pipe 430, and the nozzle pipe 440. The air supply unit 410 includes the air supply unit 410, the air supply pipe 420, the branch pipe 430, and the nozzle pipe 440, .

The aeration device 400 may be driven by electric energy to transfer the air, and a power cable may be connected to supply the electric energy or a battery may be provided.

However, since the buoyant body 100 floated in water is installed far away from the land, it is difficult to connect the power cable and it is very expensive to maintain.

Therefore, it can be installed by adding a solar power generating device using solar energy which can supply electric energy itself, a wind power generating device using wind power, or a wave power generating device using a wave power.

The apparatus according to the present invention may be provided with a solar module 500 capable of supplying electric energy by itself using solar energy.

The solar module 500 generates electric energy using solar energy, and may be installed on the upper portion of the buoyancy body 100. That is, to convert the solar energy into electric energy, and to supply the generated electric energy to the air supply module 410, which is configured to be interlocked with the aeration device 400.

Therefore, the air supply module 410 can be driven by the electric energy produced by the solar module 500, so that the air supply module 410 can be driven by itself without supplying any additional electric energy.

At this time, the solar module 500 generates electric energy mainly by using solar energy in the daytime. In the night when the function of the solar module 500 may deteriorate, the water temperature is lowered and the occurrence of algae is naturally suppressed.

Therefore, in the algae elimination and water quality improvement apparatus according to the present invention, algae elimination and water quality purification are performed by the aeration device 400 driven by the ceramic ball 300 and the solar module 500 housed in the mesh 200 during the day when the water temperature rises. In the nighttime, the ceramic ball 300 is used to remove algae and purify water. Thus, efficient operation is possible.

According to the design conditions, a wind power generation device and a wave power generation device may be added. By this configuration, electric energy can be supplied to the air supply module 410 at night as well as during the day.

The apparatus according to the present invention may further include a movement preventing device (not shown in the drawing).

The movement preventing device prevents the buoyant body (100) from deviating from a certain area and is constituted by a wire-connected precipitator.

The sedimented body can be moved to the underwater floor to prevent the buoyant body 100 from deviating from a certain area by flow velocity, algae or waves.

2 to 4 are merely the main points of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 2 to 4 It is self-evident.
