Description

A system for preventing algal blooms using aquatic plants and a method therefor

The present invention relates to a system for preventing algae using aquatic plants and a method therefor, and more specifically, it is possible to prevent the occurrence of algae in a natural environment-friendly method, as well as to expect high efficiency compared to the structure at a significantly lower cost than in the prior art. Also, it relates to a system and method for preventing algae using aquatic plants, which can contribute to the beautification of the surrounding environment.

Green algae refers to a phenomenon in which the color of water changes to green due to an increase in phytoplankton algae (blue-green algae, green algae, diatoms, etc.) in a river or lake, particularly a rapid increase in green algae and blue-green algae.

These algae play a role of phytoplankton supplying organic matter and oxygen to the water through photosynthesis during the day when there is a lot of sunlight, but at night they absorb oxygen in the water and cause low oxygen in the water, causing the death of aquatic animals such as fish. In the case of some green algae (such as Microcystis, Anabaena, Oscillatoria, Aphanizomenon, etc.) and death, so caution is required.

The influencing factors that cause algae are as follows.

First, as nutrients, factors affecting green algae cause a rapid increase in the number of algae that use them when domestic wastewater, livestock wastewater, etc., rich in inorganic nutrients such as nitrates and phosphates, are not properly treated and are introduced into rivers or lakes.

Second, as the water temperature rises, the amount of sunlight increases from spring to autumn, and when the water temperature rises by 20~30℃ or higher (especially 25℃ or higher), photosynthesis of algae is active and the rate of increase of algae affecting green algae increases rapidly. .

Third, if the inflow is insufficient due to insufficient precipitation and the flow rate is slow, the rate of increase in the number of algae using it increases rapidly due to accumulation and accumulation of the inflow pollutants (inorganic nutrients).

Therefore, it is possible to control and / or improve algae by improving the above-mentioned influencing factors, for example, when the inflow of rivers and lakes is insufficient due to insufficient precipitation in summer, the flow rate is slowed down, so that the nutrient introduced from domestic sewage and livestock wastewater The algae phenomenon occurs by stagnating or accumulating at a slowed flow rate, which causes rapid proliferation of algae using the salt, so pumping river water from the downstream of the river where algal blooms occur and transporting it to the upstream of the river using a water pipe buried underground. By re-supplying the upstream water source, it is possible to solve the shortage of inflow water in rivers and lakes and the decrease in flow rate.

In addition, the water pipe buried underground while transporting river water or lake water upstream is cooled due to the low underground heat, and the water temperature of the water passing through it is lowered, thereby suppressing the proliferation of algae caused by the increase in water temperature.

In addition, by pumping downstream river or lake water and re-supplying it to the upstream through the underground water pipe, the inflow water amount is increased to improve the problem of stagnation or accumulation of inorganic nutrient salts. Air is supplied in a saturated state to cause oxidation of organic or inorganic substances to remove pollutants, and while the transferred water is stored in an underground water tank, the water temperature is further cooled to an optimized state, and the aeration method (using a diffuser, microbubbles) is performed in the water tank. By supplying air (oxygen) through it, it is possible to remove organic matter and nutrients.

In addition, while transferring water upstream through the underground water pipe, air is supplied to the water pipe saturated with air, and air is supplied using an aeration pipe from the underground water tank, so that dissolved oxygen lowered due to algal growth can be sufficiently supplied.

On the other hand, as a system for preventing algae, a system for preventing algae from occurring in a cooling tower of Korean Patent Publication No. 10-0747737 is described.

In the above technology, a water spray tank with an open upper part to spray and store cooling water for heat exchange, a cooling tower provided with a fan for heat exchange with the sprayed cooling water, and a ventilation hole for supplying external air to the fan, and an upper portion of the water spray tank There is provided a system for preventing algal blooms in the cooling tower, which is installed in the ventilation hole of the cooling tower and includes a awning to block sunlight.

Accordingly, the invention relates to a system for preventing algal blooms in a cooling tower, which can prevent the generation and propagation of algae by covering the water tank of the cooling tower and the ventilation hole for supplying outdoor air to the inside of the cooling tower with a shading film to prevent sunlight from entering the cooling tower. However, it is known that the technique of the above document has insufficient effect compared to the structure.

Accordingly, the structure shown in FIGS. 1 and 2 has been proposed as a system for improving water quality by suppressing the generation of algae occurring in rivers or lakes.

It includes an underground water tank 10 for collecting water from the downstream; a water pipe 20 connecting the underground water tank 10 for water collection and the underground water storage tank 30 and transferring the water stored in the underground water tank 10 for water collection upstream; an underground water tank 30 for storing the water flowing through the water pipe 20 in the underground water tank 10 for water collection, cooling it with geothermal heat, and discharging it again; and an air supply unit 35 for supplying fine air in the direction of water flow in the underground water storage tank 30, wherein the air supply unit 35 is configured with a pipe for supplying air, the pipe through which a refrigerant flows. It is a method to provide the effect of vertical improvement according to the suppression of algal blooms by configuring it to include a refrigerant pipe and an air pipe through which air formed spaced apart from the refrigerant pipe flows.

In addition to this, the water wheel (2) installed in the water body where the beam (D) is installed and pumping the river water as shown in FIGS. 3 and 4; a recovery path (1) connected upstream from a water body in which a weir (D) is installed so that the river water pumped by the water wheel (2) can be sent upstream and flowed again downstream; Attempts have been made to prevent the occurrence of algae by applying a system including a water purification facility 5 for purifying river water from the recovery path 1 and flowing it upstream.

Although the above technologies can contribute to preventing the occurrence of algae, the above technologies are inevitably low in cost-effectiveness in terms of high facility costs, and above all, in that they are not eco-friendly in nature, there is a need for technology development to solve this problem. .

In particular, this system can be used as a cage to secure a large amount of space for aquatic plants and landscaping effect on the water.

By utilizing the seasonal characteristics of floating aquatic plants such as frogfish and sputum, it overcomes non-wintering, which is a disadvantage of temperate to tropical, and maximizes the effective suppression effect of algal blooms in July and September, when algal blooms occur.

For reference, look at the characteristics of aquatic plants.

First, it absorbs contaminants by contacting the roots with water as much as possible without soil, and covers the surface of the water while proliferating indefinitely. It suppresses the rise in water temperature with a shade effect.

Second, if a small amount is injected around the end of April, it can expand rapidly as the temperature and water temperature rise, and fill the water surface in July and August.

The space partitioning pattern part 130 is a part formed by dividing a space by connecting a plurality of buoyancy pots 110 . Although the space partitioning pattern part 130 is formed in a rectangular pattern in the drawings, the space partitioning pattern part 130 may be various such as a triangular pattern, a circular pattern, a star pattern, and the like. In this case, there is an advantage of providing a beautiful aesthetic feeling by itself.

The floating aquatic plant 140 is a plant that is vegetated in the space partition pattern part 130 to prevent algae. It is preferable that the aquatic plant 140 has a floating function, rather than a general plant because it should float on water.

In this case, there is an advantage of providing a beautiful aesthetic feeling by itself.

Then, as shown in FIG. 6 , the floating aquatic plants 140 are vegetated in the space partitioned by the buoyant pots 110 .

In this way, if a space is partitioned and formed through a buoyancy pot 110 at the waterside of a weir or lake, and each space is filled with floating aquatic plants 140 through vegetation growth, buoyancy occurs at the time of occurrence of green algae. Generation of algae can be prevented through the oily aquatic plant 140 . In addition, various designs can contribute to environmental beautification.
