System for Water purification and Anti-Green Algae Using Underground water}

The present invention relates to an algae prevention and water purification system using groundwater, and more specifically, groundwater having a lower temperature than the surface water through the spray nozzle head of the sprayer on the surface of the green algae generating area in a place such as a river, a river or a lake. The present invention relates to a green algae prevention and water purification system using groundwater, which is sprayed to suppress the growth of green algae by inhibiting the growth of green algae by lowering the water temperature.

Generally, algae phenomena are rich in perishable organic pollutants, trace metals and growth promoting substances, and environmental conditions such as insolation and water temperature are required. Among these, the increase in summer water temperature is the most important condition for breeding and spreading green algae. It is said to be.

In other words, when excessive amounts of living sewage and manure containing organic matter flow into rivers, lakes, rivers, etc., microorganisms decompose organic matters excessively, resulting in eutrophication of nutrients in the body of water, which causes plants and green algae to thrive and biological oxygen demand. (Biochemical Oxygen Demand, BOD) increases, and the lack of oxygen in the water leads to an environment in which aquatic organisms such as fish cannot live. .

In particular, when the temperature rises, stratification is intensified, and when oxygen from the lake surface becomes difficult to transfer to the lake bottom, the dissolved oxygen in the bottom of the lake drops sharply, and as a result, the destruction of the ecosystem becomes worse. Although a device for improving water quality is required, it is difficult to prevent water deterioration and aesthetic discomfort caused by the occurrence of habitual algae every year due to excessive cost burden caused by green algae removal.

In view of this, the present invention discloses an anti-green algae water circulation device using the solar light of Patent No. 10-0965784, the configuration of which is provided in a hollow body having a hollow body located in the body of water, the lower end of the body and the water body.

Such a sprayer 10 is to be installed on the land and water, and when installed on the land is provided with a fixing portion of the needle-shaped in the lower portion of the support 12 to be plugged into the ground so that the installation position can be changed This is preferred.

In addition, when the sprayer 10 is installed in the water, it is fixed to the upper surface of the buoy 40 made of Schiropol, etc. to float on the water, but the buoy 40 is connected to the four corners of the rope 44 Connected to maintain the fixed state in the configuration to be supported by the weight body 42 is installed on the bottom surface, or by connecting the connecting rope 44 in a loose form to move in a certain range along the water surface or ascend Do it.

In addition, when the sprayer 10 intends to synergize only along the surface of the water in the fixed position, the guide roller 46 is installed at the corner of the float 40 to be connected to the weight body 42 and have a constant weight. When the water level is lowered by guiding the connecting rope 44 with the retaining member 48 while the float 40 is lowered, the tension retaining member 48 is lowered along the guide roll 46 and the water level is increased. When the tension retaining member 48 rises along the guide roller 46 in the opposite operation, the float 40 can be lifted in the state in which the connecting rope 44 is tightly supported.

The water supply unit 20 directly excavates the ground to take ground water through a pump or the like, and then directly connects the water supply line 30 to the head 14 of the sprinkler 10 through the water supply line 30 to lower the low temperature of the ground water. Injection is performed through the injection nozzle 16 of the unit 14.

Since the water supply line 30 may increase the temperature of the ground water flowing to the water supply line 30 when exposed to sunlight, it is preferable to install the water supply line 30 or to cover the insulation cover.

In addition, the present invention is provided with a branch pipe 50 connected in parallel to the water supply line 30, provided with on-off valves 52, 52 'on both sides of the branch pipe 50 and the on-off valves 52, 52' Cooling device 54 such as a heat pump is connected between the water supply pipe in order to lower the temperature of the ground water taken by the cooling device 54, or when the intake of the ground water is insufficient. Through (56) to allow the water to be supplemented by using the lake or river water while the water temperature is lowered to the water supply to the water supply line 30 through the pump (P).

In the present invention as described above, as shown in FIG. 1, the spraying water sprayer 10 is installed on the surface of the green algae generating area A in a place such as a river, a river, a lake, etc., and the water is collected at a lower temperature than the surface water.

At this time, the ground water taken in is a low water temperature with a water temperature of about 15 to 17 degrees. Therefore, the temperature of the surface of the algae is suppressed and the temperature of the algae is reduced to prevent the algae growth. Purified.

Generally, when green algae occur, there is a property of drifting to the upper water surface (photosynthesis by light), so spraying groundwater with a large water temperature difference of about 7 to 10 degrees in surface water will cause it to go down and inhibit suffocation or growth. In addition, by spraying on the surface using the low pH (neutral) of the groundwater brings about the effect of lowering the high pH (alkaline neutral) caused by the algae.

In addition, the present invention is sprayed according to the water pressure, rotation angle of the water spraying machine 10, because the water droplets fall on the surface irregularly and extensively, water ripples occur as a heavy rain, resulting in numerous bubbles, water purification effect as well as its The ripple results in refraction and scattering of sunlight due to the wavelength, and the transmittance is halved to suppress the occurrence of green algae and growth.

In addition, it is possible to apply a variety of green algae remover (environmental product) to the sprinkler 10 through the ground water supply line in parallel without applying a separate device, thereby double the green algae prevention and reduction effect.
