Description

(Prevent algae and green algae in lake water purification devices for removing)

More particularly, the present invention relates to a water purification apparatus for preventing green algae and removing green algae from a lake, and more particularly, it relates to an apparatus for purifying water of a lake by partially floating on the water surface by magnetic levitation, The present invention relates to a water purifying apparatus for preventing green algae and removing green algae in a lake, wherein the anion is caused to agglomerate green algae using an anolyzing means and the cation is reacted with fresh water to supply oxygenated water to increase the amount of dissolved oxygen in fresh water.

In order to prevent the occurrence of algae phenomenon mainly in cyanobacteria in the lake or to remove already blooming cyanobacteria, it is necessary to remove P or N component which can flow from outside and promote bird propagation. In addition, in the case of lakes and reservoirs, the main cause of the green algae is the stagnant water with a long hydraulic retention time. Of course, pollution sources such as nitrogen and phosphorus from the outside are the main causes. On the other hand, It is the cause of growth.

If it can supply smooth dissolved oxygen supply and water flow, it can accelerate algae death by accelerating the growth of aerobic microorganisms, which constitute other normal ecosystems in the water, so that the dominant power can be eliminated. One example is to install an aerator in a small pond to actually provide water flow and oxygen.

Physico-chemical methods (eg, aquaculture, chemical administration, etc.) developed for the purification of existing lakes require excessive management costs compared to lake size and provide pollution sources such as forming sediments at the bottom of the lake In addition, if the size of the lake itself is large, it is practically impossible to purify the lake by applying these techniques.

On the other hand, there is a lack of data on the treatment efficiency of the water purification method that can be installed in the lake's inflow rivers and lakes, and the effect of various water purification methods on the lake water quality improvement is insufficient. The aim is to develop technology.

Therefore, in order to solve the water quality problem of the lake, proper aeration function, water flow and drug input can be effectively improved. As mentioned above, currently applied fountain or aeration by water has a disadvantage that it is not applicable to a large lake because the power ratio is excessive and the amount of water actually aeration is small. It is also expensive to inject coagulant into the lake, and if the sediment is deposited and accumulated on the bottom and anaerobicized, the nutrient salts will be re-eluted to remove the bottom sediment or to continuously inject the coagulant. Therefore, aeration is installed in a highly efficient circulation type to maximize the exposed surface of the water at the bottom. The power required at this time is a hybrid system that uses solar and wind simultaneously. I did not need it. Nutrients in the lake water are coagulated with natural coagulant or loess when the amount is excessive, and the lake is maintained in aerobic condition so that the yogurt salts such as nitrogen and phosphorus are not re-extracted from the bottom of the lake.

Particularly, as the basic factors of abnormal growth of algae in lakes and reservoirs, proper nutrient salts, light, water temperature, residence time, etc. Can be mentioned, and the proliferation of algae is remarkable from the water surface of summer stagnant with high amount of sunlight and high temperature, . Nutrients that enter the lake or reservoir are ingested by surface algae and promote growth. Especially during the summer season when stratification begins to occur, nutrients (nitrogen, phosphorus, etc.) rising from the bottom of the lake due to sufficient sunlight, up-and-down circulation in spring and reversal phenomenon and nitrogen and phosphorus into the lake, So that hydration or fresh water red tide can be generated.

Algae, which are mainly grown in summer stagnation, are propagated by nutrient salts, but some of them are deposited on the bottom of the lake after being killed and deposited as organic matter. Deposited organic matter is initially degraded by bacteria under aerobic conditions and consumes dissolved oxygen at the bottom of the lake during degradation, resulting in a lack of oxygen in the lake. Therefore, when oxygen is depleted on the bottom of the lake and it changes to anoxic state, iron or manganese is reduced and eluted from the deposited layer, causing coloring obstacles such as enemy water or black water.

In view of the above problems, Korean Patent Registration No. 951787 has proposed a self-generating water purification apparatus for a sanitary water area. In the conventional water purification apparatus, the impeller is rotated by the sunlight and the wind force so that the water remaining in the corrugated pipe and the flocculant supplied at the bottom of the impeller are mixed well. The flocculant is supplied by the water purifier, To the four directions of FIG.

The above-mentioned Korean Patent Registration No. 951787, in which the flocculant is supplied to water to diffuse to the four corners of the congested waters, has the disadvantage that the flocculation agent has to be filled in the tank and the flocculation agent elutes, There is a problem.

Meanwhile, Korean Patent Laid-Open Publication No. 2001-48041 discloses a method for removing red tide and green tide using an electric levitation and a device therefor. In this method, a plurality of electrode plates for supplying an electric power to form an electric field, and a plurality of electrode plates alternately, And a plurality of electrode plates are integrally coupled to each of the plurality of electrode plates so as to hang vertically in parallel at regular intervals and power supply means is mounted on the upper surface of the electrode plates, And a buoyancy member for providing buoyancy to float in the water when the power supply means is coupled.

When this device is connected to a boat, then a suction device is connected to the reddish area, or the vicinity of the watercraft is surrounded by this device and a suction device is installed behind the device, Flocculated by the formed electric field and floated above the water surface, and the floating red tide or green tide sludge is removed by suction device.

Korean Patent Laid-Open Publication No. 2001-48041 discloses that the red tide and green tide sludge are floated on the water surface while being flocculated by the electric field formed between the electrode plates, but the sludge is removed by the suction device. However, When the flocculation occurs, the flocculant can not float on the surface of the water due to its weight. Therefore, the red tide or the green tide sludge floated on the water surface can not be removed by the suction device and the removal efficiency is lowered.

FIG. 1 is a perspective view showing the outline of a water purification apparatus of the present invention. FIG. 2 is a sectional view showing the structure of a water purification apparatus 1 according to the present invention. A control means 100 connected to the circulating means 400 for controlling each means and a suction passage 210 for sucking water and green algae from the water surface are formed and a discharge port 220 connected to the suction passage 210 at the center A buoyancy body means (200) for floating the buoyant body means (200) floating by buoyancy on the water surface and sucking the green algae remaining on the water surface, a moving pipe (300) for moving the water on the water surface below the water surface, 200 for generating electricity by the rotational force of the fluid circulating and moving means (400) and a power generating means An anion generating means 600 connected to the stage 500 and the power generating means 500 and fixed to the moving pipe 300 to coagulate the green algae contained in the fresh water of the surface by generating negative ions, And a fixing unit 700 for connecting the weight 710 to the loops 720 and stopping the weight 710 on the water surface.

The buoyancy body means 200 uses a light and durable material. The fluid circulating and moving means 400 includes a moving impeller 430 for moving the fresh water toward the bottom of the lake or dam or the like at the lower end of the rotating shaft 420 of the wind turbine 410 rotated by the wind.

A power generating means 500 generating and accumulating electricity is connected to a certain portion of the rotating shaft 420 by using the rotational force of the rotating shaft 420. The negative ion generating means 600 is made of a power generating means 500 And the negative potential is discharged in the state of being contained in fresh water by using an electrode.

As shown in FIG. 3, the bottom surface of the suction passage 210 may be inclined toward the center of the suction passage 210, The impeller 211 can be further installed.

In addition, as shown in FIGS. 6 and 7, the power generating means 500 may be connected to a cooling means 800 for supplying a low temperature. The cooling means 800 generally compresses and evaporates the refrigerant, , A cooling device that expands and performs heat exchange, and a thermoelectric device that uses electrical energy can be used.

The operation of the water purification apparatus 1 of the present invention having the above structure is performed by floating the buoyancy body means 200 on the fresh water such as a lake or the like and moving the weight weight 710 connected by the loops 720 down to the buoyancy body means 200 ) Is fixed so as not to move.

The wind turbine 410 is rotated when the buoyant body means 200 is installed on the water surface and the rotational axis 420 connected to the wind turbine 410 is also rotated with respect to the wind turbine 410 .

On the other hand, when the rotating shaft 420 is rotated, the moving impeller 430 for moving the fresh water toward the bottom of the lake or the dam is rotated at the lower end of the rotating shaft 420 to move the fresh water downward.

When the moving impeller 430 is rotated, green algae and fresh water on the side of the water surface are sucked toward the center of the buoyancy body means 200 through the suction passage 210 and are moved by the moving pipe 300 installed on the discharge port 220, The flow direction of the fresh water is changed from horizontal to vertical.

When the fluid circulating and moving means 400 is operated by the wind, electricity is generated and stored at the generator means 500 connected to the rotating shaft 420 according to the wind speed. The negative ion generating means 600 is connected to the power generating means 500 to discharge the negative potential generated by the power generating means 500 into the fresh water using the electrode.

When the anion is released by the electrode, the green algae flocces to the bottom because it is aggregated with the anion and has a weight. Therefore, the green tide generated in the lake is removed.

On the other hand, the green tide occurs when the water temperature is maintained above a certain temperature. Therefore, the present invention uses the cooling means 800 to keep the temperature of the fresh water below a certain level as shown in FIGS. 6 and 7. The cooling means 800 may be any one of a cooling device that performs heat exchange by compressing, evaporating, and expanding the refrigerant, and a thermoelectric device that uses electric energy.

As described above, the present invention coagulates by the negative ion generating means 600 and sinks to the sediment layer. If the temperature of the fresh water is below a certain temperature, green tide is not generated. Accordingly, the present invention is based on the fact that a part of the water floats due to magnetic levitation, sucking the green algae and fresh water floating on the water using wind power, generating anions in the inhaled fresh water to aggregate the green algae, So that the amount of dissolved oxygen in the fresh water is increased to prevent the green algae, and the water temperature is lowered to remove the green algae and the generated green algae.

In the present invention, it is described that self-power generation is performed using wind power, but self power generation can be performed using sunlight.

If the wind power is insufficient, the fluid circulation means 400 may be operated using electricity generated according to the power generation amount. Alternatively, the anion generation means 600 connected to the power generation means 500, The cooling means 800 shown in Fig.
