The present invention relates to a pond purifier for improving the water quality of the pond, more specifically, it is easy to inject a gas (O₂, O₃) useful for water quality management, and to increase the dissolved oxygen in the pond to contaminate water The present invention relates to a pond purifier that enables the control of water quality of a pond more effectively by suppressing the occurrence of algae and anaerobic bacteria.
Ponds are rich in algae nutrients, and if oxygen is not supplied enough to oxidize the nutrients, algae will thrive excessively, causing red tide, which leads to severe eutrophication. .

Accordingly, when the amount of dissolved oxygen decreases, turbidity increases, resulting in a vicious cycle of breeding, growth, and extinction of algae.

In addition, when there is no oxygen or a low anaerobic environment, anaerobic microorganisms generate hydrogen sulfide or methane gas, causing odors. In particular, when there is no fluidity such as a pond or reservoir, oxygen supply is insufficient. As such, it is necessary to forcibly supply the pond with a gas (O ₂ , O _3, etc.) or a liquid (pH regulator, algae, photosynthetic blocker, flocculant, etc.) useful for water quality control.

7 is a plan view for explaining a pond purification apparatus according to the prior art, a plurality of fluid supply means useful for water quality management is disposed inside the pond (1 '), they are each used for water quality management by the pump pressure It is configured to supply useful fluid to the inside of the pond and to supply the fluid to a relatively distant place by causing a fluid flow in a constant direction (counterclockwise in the embodiment of FIG. 7) to occur.

However, in the prior art, since each fluid supply means requires a separate pump, and in most cases, only the fluid flow in a predetermined direction is formed by a plurality of fluid supply means, the shape of the pond edge as shown in FIG. If the bending is severe and complicated, there is a problem that a blind spot such as a hatched portion occurs.

Meanwhile, in the prior art, when a liquid is injected as a fluid useful for water quality management, a chemical storage tank, a metering pump, an injection tool (KIT), a controller, and the like are required, and when a gas is injected, the gas is generally dissolved in water. Accessories such as treatment tanks, diffusers, etc. are required, and if a treatment tank is not provided, a separate pressurized melting tank is required. In addition, since a single device cannot treat liquids and gases together, each of the gases useful for water quality management such as O ₂ , O ₃ , and liquids such as pH regulators, agicides, photosynthetic blockers, and flocculants can be treated together. There is a problem that must be installed separately.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a pond purification apparatus which can prevent a pond from being easily polluted and decayed, and can greatly reduce their maintenance cost.

In addition, the present invention is to minimize the gas loss when injecting gas into the chemical liquid, and to provide both the gas and the liquid by a single device to significantly reduce the installation cost and maintenance costs of another device Is there.

In order to achieve the above object, in the present invention, the water drawn from the intake port located at the deepest of the pond can be uniformly refluxed without stagnation by the chemical supply pipe installed along the edge of the pond. By supplying a plurality of venturi nozzles each time, which automatically sucks and supplies the air, it is possible to supply chemicals evenly to the curved part of the pond and to maintain a large amount of dissolved oxygen. By allowing gas such as O ₂ and O ₃ to be supplied with the liquid, it is possible to drastically reduce the facilities cost and maintenance cost.

As such, the present invention increases the dissolved oxygen in the fresh water in the pond by greatly lowering the biological oxygen demand (BOD) or the chemical oxygen demand (COD), thereby greatly reducing the amount of oxygen in the water that becomes the pollutant of the pond. By oxidizing and sterilizing algae and organic substances, they can greatly contribute to the purification of ponds.

Hereinafter, the constitution and effects of the present invention will be described with reference to the accompanying drawings.

1 and 2, the pond purification apparatus according to the present invention, the intake port 5 located in the deep portion of the pond (1), and the suction line connected between the intake port (5) and the pump (P) 3) and a long one or more rotations along the pond edge line 2 to supply the chemical liquid supplied from the pump P evenly over the pond, and the end portion 41 is closed with the chemical liquid supply pipe 4. And a plurality of connecting pipes 9 branched inwardly at predetermined intervals from the chemical liquid supply pipe 4, and an air suction pipe 6 connected to the front end of the connecting pipe 9 and communicating with the atmosphere at the center thereof. It consists of the venturi nozzle 7.

That is, a plurality of connection pipes 9 are branched to the chemical supply pipe 4 at predetermined intervals, and venturi nozzles having air intake pipes 6 exposed out of the water surface by a predetermined height at each end of each connection pipe 9. (7) is provided to supply oxygen in the air through the air suction pipe (6) to increase the amount of dissolved oxygen.

In addition, the present invention may include a chemical solution injection device 8 for separately supplying a microbial culture medium and a chemical solution (pond clarifier, etc.) useful for water quality control of the water returned to the pond along the chemical solution supply pipe (4), the chemical solution injection The device 8 is connected between the discharge port of the pump P and the chemical liquid supply pipe 4.

Since the intake port 5 absorbs the water of the pond and the venturi nozzle 7 discharges the chemical liquid, the fluid flow is formed as shown by the arrow.

On the other hand, since the chemical liquid supply pipe (4) is formed long along the pond edge line (2), the overall configuration is similar to the shape of the pond, the pump (P) is a venturi nozzle connected to the end of the chemical liquid supply pipe (4) Also in (7), it is to be designed to create a sufficient pressure to eject the chemical liquid.

In addition, the intake port 5 is to be installed in the deep portion of the pond to facilitate the intake by the water pressure, the connecting pipe 9 and the venturi nozzle (7) is an air supply pipe connected to the middle of the venturi nozzle (7) The tip of (6) is preferably installed at a relatively upper portion so that it is easy to be exposed to the atmosphere, and the outlet of the venturi nozzle 7 should be provided so as to face the center of the pond.

On the other hand, Figure 3 is an enlarged side cross-sectional view showing only the venturi nozzle, which is an essential part of the present invention, the venturi nozzle 7 has a cross-sectional area of the intermediate portion to which the air intake pipe 6 is connected is formed smaller than the cross-sectional area of the inlet and outlet, the venturi nozzle The fluid passing through the nozzle 7 has a faster flow rate in the middle portion, and according to Bernoulli's principle, the pressure drops below atmospheric pressure. Therefore, the atmosphere flows into the venturi nozzle 7 through the air suction pipe 6 and is blown out of the venturi nozzle 7 together with the chemical liquid supplied from the connecting pipe 9 by hydraulic pressure.

Figure 4 is a side cross-sectional view for explaining the chemical liquid supply pipe which is the main part of the present invention, (a) is an illustration showing a state in which the chemical liquid supply pipe is connected lower than the connecting pipe, (b) is a state in which the chemical liquid supply pipe is connected higher than the connection pipe It is an exemplary diagram showing the.

First, as shown in (a) of FIG. 4, when the connecting pipe 9 is connected lower than the chemical supply pipe 4, if only liquid is mixed into the chemical liquid, there may be no problem, but as shown in the illustrated embodiment, the liquid 42 and the gas ( When the 43 is mixed together and divided into upper and lower parts, the gas 43 is located on the side of the connecting pipe 9 coupled with the venturi nozzle 7, so that the gas 43 may be released even without dissolving in the chemical liquid. . Therefore, in this case, there is a problem that the waste of the gas is severe when the chemical liquid contains a gas useful for water quality management, such as O ₂ , O ₃ .

On the contrary, when the connecting pipe 9 is connected lower than the chemical supply pipe 4 as shown in FIG. 4 (b), the liquid 42 is in contact with the venturi nozzle 7 even when the liquid and gas are mixed together in the chemical solution. Since it is located on the side of the coupling tube 9, the gas 43 cannot be released without being dissolved in the chemical liquid. Therefore, the embodiment of Figure 4 (b) does not waste the gas contained in the chemical compared to the embodiment of Figure 4 (a) can be used more economically.

On the other hand, the present invention includes a separate chemical liquid injection device 8 to automatically inject the microbial culture medium and the chemical liquid (pond purifier, etc.) useful for the water quality management of the water returned to the pond along the chemical liquid supply pipe (4), the chemical liquid The injection device 8 is connected in parallel to the chemical supply pipe 4 adjacent to the intake port 5 as shown in FIG. 5 so that the chemical liquid automatically supplied from the chemical injection device 8 is evenly supplied to the pond through the chemical supply pipe 4. Can be.

That is, the branch pipe 81 of the chemical liquid injection device 8 is connected in parallel with the chemical liquid supply pipe 4, the middle portion of the branch pipe 81 is connected from the gas generator and / or the water purifier storage tank 84 Venturi pipe 82 is connected to the suction pipe 83 is connected in the middle.

Therefore, when water introduced through the water intake port 5 by the pump P passes through the chemical liquid supply pipe 4, the branch pipe 81 is connected to the chemical liquid supply pipe 4 in parallel, so that some of the water is It flows into the branch pipe (81).

In addition, the water flowing into the branch pipe 81 passes through the venturi pipe 82, the suction pipe 83 connected from the gas generator and / or the water purification agent storage tank 84 in the middle of the venturi pipe 82. Since this is connected, the fluid supplied through the suction pipe 83 is introduced into the venturi tube 82 by the Bernoulli principle, and the fluid supplied into the venturi tube 82 is introduced into the branch pipe 81. It is mixed with the prepared water and continues to be supplied through the chemical liquid supply pipe (4).

If you want to include only gases (O ₂ , O _3, etc.) that are useful for water quality management in chemicals, 84 is the gas generator, and liquids that are useful for water quality management in chemicals (pH regulators, algae, photosynthetic blockers, flocculants, etc.) ), The reference 84 corresponds to the water purifier storage tank, and if the chemical liquid contains both gas and liquid, the reference 84 corresponds to both the gas generator and the water purifier storage tank.

Such a chemical liquid injection device 8 has an advantage that the structure is simple, construction cost, operation cost and maintenance cost are low, and gas and liquid injection can be solved as one device.

On the other hand, if you want to supply the gas containing the gas useful for water management, the process for mixing the gas and water is required in order to supply the gas in a state that the gas is sufficiently dissolved (mixed) in the water, in the present invention This was solved in the same manner as in FIG. 6.

That is, the front portion of the chemical liquid supply pipe (4) is formed with a length sufficient to mix the gas and water inlet 44 is not coupled to the connecting pipe 9 and the venturi nozzle (7), the rear of the connecting pipe ( 9) and the vent part 45 to which the venturi nozzle 7 is coupled is integrally connected. The chemical liquid supply pipe 4 is a closed space in which the end 41 is closed, and the introduction part 44 serves as a kind of gas dissolution treatment tank, so that it can be completely dissolved without a treatment tank or an expensive dissolution tank. have.

In the illustrated example, the chemical liquid supply pipe 4 is configured in the form of two turns of the edge of the pond, and the initial one rotation is composed only of the inlet 44 serving as a gas dissolving tank, and the remaining part is composed of the outlet 45. However, the ratio of the length between the inlet 44 and the outlet 45 may be arbitrarily adjusted according to the diameter of the pipe, the pressure of the pump, and the type of gas used.

In the pond purification apparatus of the present invention configured as described above, when the pond 1 becomes cloudy, the pump P of the intake port 5 is operated. In this case, the turbid water in the pond 1 is discharged by the pump P. After flowing into the chemical liquid supply pipe (4) through 5), the high pressure is injected to the outside through the connecting pipe (9) and the venturi nozzle (7).

If this is operated for a predetermined time or more, the water in the pond 1 is sucked by the air pressure difference generated when the air in the air flowing through the air suction pipe 6 exposed to the water surface passes through the venturi nozzle 7. By dissolving in water in a fine bubble state, it is possible to maintain an excellent dissolved oxygen amount as much as 12 to 20 times the oxygen transition effect compared to a conventional fountain system.

As such, the present invention significantly increases the amount of dissolved oxygen, while reducing the biological oxygen demand (BOD) and the chemical oxygen demand (COD), thereby oxidizing all of the freshwater algae and organic substances in the water, which are pollutants of the pond. Even the virus has the advantage of sterilization, disinfection.

And the chemical liquid supply pipe (4) is installed along the edge of the pond, that is, the boundary portion is easy to install even in the deep bends and shallow parts to spray deep low-temperature water rich in dissolved oxygen, and the new supply of water rich in dissolved oxygen When organic matter is oxidized at the edge of the pond, nutrients such as algae are blocked and water purification proceeds.

As described above, in the present invention, the stirring and circulation of the deep water (low temperature, anoxic state) and the surface water (high temperature, oxygen saturation state) of the pond are carried out quickly and actively, eliminating the water temperature difference between the two, and the anaerobic bacteria It suppresses growth and propagation, and even reflux of the pond edge no matter how severe the circulation area, it raises the dissolved oxygen easily without extra power and makes the pond itself oxygen saturation. Oxidation inhibits algae generation and automatically injects water and gaseous water purifiers into the pond with a single device. When injecting gas (O ₂ , O _3, etc.) useful for water quality management, it can achieve 100% solubility without using a separate treatment tank or expensive dissolution tank, eliminating the waste of expensive gas (O ₂ , O _3, etc.) This minimizes installation and operating costs and maximizes water purification.
