Description

Lake water purification device

The present invention relates to a water purification device, and more particularly, to an improved lake water purification device which is simple in structure, can maximize the amount of oxygen dissolved in water, and can remove contaminants present in the water. .

In general, nutrients such as phosphorus and nitrogen continuously flow into reservoirs such as ponds and lakes where water is stored. When there is no outflow route of the nutrients introduced in this way, algae and phytoplankton in the reservoir will overproduce while consuming oxygen dissolved in water. Accordingly, oxygen dissolved in the water may be depleted and eutrophication may occur, and as a result, fish waste may be killed.

Underwater ecosystems are preferably balanced at some level. The balance of the ecosystem is possible when the nutrients in the water are kept below a certain level, so that the rate of reproduction of algae and plankton in the water is kept below a certain level.

Therefore, a water purification apparatus is used to prevent the water quality of the reservoir from being contaminated. Water purification devices for improving water quality have been proposed in various forms. In recent years, a device for forcibly generating bubbles in water is used. This water purification device is used to increase dissolved oxygen in water and to vertically circulate the water.

3 is a cross-sectional view of a conventional water purification device.

Referring to FIG. 3, the conventional water purification apparatus 10 includes a cylindrical body 11 and a connection member 12. The connecting member 12 is mounted on the bottom of the main body 11. The hinge 14 is installed below the connection member 12. The connecting member 12 is connected to the weight body 15 by the hinge 14. The weight 15 is adjacent to the bottom of the reservoir. A plurality of floats 16 are installed around the upper portion of the main body 10. The exterior 18 is protruded around the lower outer periphery of the main body 11. An air chamber 20 is formed between the main body 11 and the exterior 18 to enclose the main body 11 in a circular shape. A plurality of bubble tubes 21 are formed in the lower portion of the air chamber 20. Bubble holes (not shown) are formed at both sides of the bubble tube 21. The U-shaped induction pipe 22 is fixed to the upper portion of the connection member 12 in the lower portion of the air chamber 20. The injection port 24 is installed at an upper portion of the air chamber 20. The high pressure hose 26 for introducing outside air is connected to the upper portion of the inlet 24.

The conventional water purification device 10 having the above-described configuration is fixed to the bottom of the lake by the weight of the weight body 15, and is installed vertically by a plurality of floats 16 installed on the upper portion of the body (11). It works.

When bubbles are generated by using the water purification device 10, compressed air is supplied through a high pressure hose 26 for diving using a compressor (not shown) that is separately installed outside the reservoir. Compressed air flows into the inlet 24 of the air chamber 20 connected to the high pressure hose 26. Subsequently, the compressed air is introduced into the air chamber 20 and then discharged into the plurality of bubble tubes 21. The compressed air introduced into the bubble tube 21 is discharged through the bubble hole formed in the bubble tube 21. The compressed air discharged from the bubble holes pushes the water inside the exterior 18 downward, and is formed as one large bubble inside the exterior 18. Air bubbles formed inside the exterior 18 pass through the induction pipe 22 and move upward along the interior of the main body 11. Air bubbles that have completely passed through the main body 11 are moved upward in the water and are discharged to the water surface. Ellipses and arrows shown in the main body 11 show the bubbles and the direction of movement of the bubbles.

By the way, since the above-mentioned water purification apparatus 10 uses a plurality of apparatuses, its structure is complicated and the manufacturing cost increases. In addition, since the air bubbles are formed large, the surface area of the air bubbles is not wide, so the amount of dissolved oxygen is small, and the water quality improvement effect is weak. In addition, since the fine contaminants and other contaminants cannot be sufficiently removed, a separate device for removing the micro contaminants and other contaminants is required.

The present invention is designed to solve the above-mentioned problems, the object of the present invention is to improve the simple structure, can maximize the amount of oxygen dissolved in the water, can remove the contaminants present in the water To provide a lake water purification device.

1 is a perspective view of a lake water purification device according to the present invention, Figure 2 is an exploded perspective view.

1 and 2, the lake water purification apparatus 100 according to the present invention mainly includes an oxygen transfer device 200 and a water purification aid 300.

Oxygen transfer unit 200 has a rectangular base 202. The base 202 has a rectangular box shape with an open top and a closed bottom. An open upper portion of the base 202 is provided with a porous ceramic plate 206 having fine pores. On four sides of the base 202, a connecting member 204 is formed extending upward. One side of the base 202 is provided with an inlet 208 for receiving the compressed air supplied from the outside. The inlet 208 is connected to the high pressure self-weight hose 210. A pedestal 212 is formed on the upper portion of the inlet 208 extending outwardly perpendicular to one side of the base 202. A fixing piece 214 for fixing the chemical injection tube 213 is installed on the upper portion of the pedestal 210. The first receiving hole 215 penetrates through the connection member 204 of the base 202.

The water purification aid 300 is detachably installed on the base 202 of the oxygen transfer device 200. At the four corners of the base 202, the first support member 302 of the water purification aid 300 is located. A fixing member 304 is installed below the first supporting member 302 to connect the respective first supporting members 302 to the side surfaces of the oxygen transfer device 200.

Referring to FIG. 2, the first fixing groove 205 is formed in the middle of the three connection members 204 except for the surface on which the first receiving hole 215 is formed, and the surface on which the second receiving hole 315 is formed. A second fixing groove 305 is formed in the middle of the three fixing members 304 except for the one. The first fixing groove 205 and the second fixing groove 305 are coupled by the bolt 322 and the nut 324. Accordingly, the oxygen transfer device 200 and the water purification auxiliary device 300 are combined.

The second receiving hole 315 is formed in the fixing member 304 of the surface which is in contact with the connecting member 204 where the first receiving hole 215 is formed. The chemical injection tube 213 passes through the first receiving hole 215 and the first receiving hole 215, and its end is placed on the center of the porous ceramic plate 206.

Referring back to FIG. 1, a second support member 303 is installed in a middle portion of the first support member 302 to connect and support the first support members 302. Similarly, a third support member 305 is installed on the upper portion of the first support member 302 to connect and support the first support members 302. The first support member 302, the second support member 303 and the third support member 305 form a filling. Fill 310 is defined by a mesh 312. The mesh 312 is made of steel, plastic or fibrous mesh. In addition, the inside of the filling box 310 is filled with a filler 314. Filler 314 may be changed in kind depending on the desired effect. If it is desired to remove the micro-pollutants, it is filled in the activated carbon (310). In addition, when the phosphorus compound and other contaminants are to be removed, a solid alum and iron salt may be added to induce a natural aggregation and precipitation effect. In addition, by inserting a ciliary material into the filling box 310, it is possible to induce the aerobic adherent algae to decompose nutrients and organic substances.

Hereinafter, the operation of the lake water purification apparatus according to a preferred embodiment of the present invention is as follows.

In order to operate the lake water purification apparatus 100 according to the present invention, the compressed air is supplied to the high-pressure self-weight hose 210 by using a compressor (not shown) that is separately installed outside the reservoir. Compressed air is supplied to the porous ceramic plate 206 via the inlet 208. Since many pores are formed in the porous ceramic plate 206, compressed air is discharged upward through the pores. At this time, since the bubbles released are fine in size, the total surface area of the bubbles increases compared to that of one large bubble. Thus, the amount of oxygen dissolved in the water increases, so that the dissolved oxygen is significantly increased. In addition, due to the rise of air bubbles in the reservoir is a vertical circulation of water. Accordingly, it is possible to suppress the use of solar energy required for algae photosynthesis to suppress the growth of algae.

On the other hand, when it is necessary to supply the chemicals for water treatment to the water of the reservoir, the chemicals for water treatment to the chemical inlet pipe 216 fixed to the fixed piece 214 of the oxygen transfer device 200 by using a metering pump from the outside Supply. Since the distal end of the chemical injection tube 216 is located at the center of the porous ceramic plate 206, the diffusion speed of the chemical is accelerated by the diffusion of minute air bubbles emitted from the porous ceramic plate 206. Accordingly, the mixing of the drug in the water body is made in the shortest time, thereby maximizing the effect of the water treatment. In addition, since the chemical supply for water treatment of the reservoir is performed outside the reservoir, the supply of the chemical becomes easy.

The improved lake water purifying apparatus according to the present invention can maximize the amount of oxygen dissolved in the water, and can vertically purify the water body of the reservoir. In addition, it is possible to treat the fine contaminants and other contaminants, and can easily and effectively treat the water treatment chemicals.

Although one embodiment of the present invention has been described in detail with reference to the accompanying drawings, the present invention is not limited thereto, and improvements or modifications thereof can be made within the ordinary knowledge of a person skilled in the art.
