Figure 5 is a front view showing the main portion of the water purification device according to another embodiment of the present invention.

Hereinafter, a floating water purification apparatus according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

1 to 3, the water purification apparatus 10 of the present invention is mainly installed in a closed water body that is stagnant and inactive in water, such as a lake, a bay, an estuary area, a dam, a reservoir, a pond, a farm, etc. Can be used.

Floating water purification apparatus 10 according to an embodiment of the present invention is largely floating body 20, aeration unit, self-generating unit 40, power supply unit, the movement limiting unit, bioreaction unit 70 ).

As the floating body 20, conventional materials such as wood, resin, metal, foam, etc., which can float on the water surface can be used. Preferably, the floating body 20 includes a base member 28 and a housing 20 installed on the base member 28.

The base member 28 is to give a certain weight to the floating body 20, and is formed in a conical shape that gradually decreases in cross-sectional area as it progresses downward. The lower end of the base member 28 is formed with a first ring 51 to which the first fixing rope 53 to be described later is coupled.

The housing 21 is formed in a cylindrical shape and installed above the base member 28. At this time, the housing 21 is fixed to the base member 28 using conventional fixing members. An empty space having a predetermined size is formed in the housing 21, and the inner space is partitioned by a plurality of partitions 23 to provide a plurality of fluid storage chambers 25. Each of the fluid storage chambers 25 is enclosed and fills the fluid storage chamber 25 with a fluid smaller than the specific gravity of the water to impart buoyancy to the base member 28. In addition, each fluid storage chamber 25 may be filled with air or water to adjust the buoyancy force applied to the base member 28. In the illustrated example, six fluid reservoirs 25 are formed in the housing 21 by five partitions 23. When air is filled in each of the fluid storage chambers 25, the buoyancy acts greatly on the base member 28, and some of the fluid storage chambers 25 fill air and fill the remaining fluid storage chambers 25 with water to act on the base member. The buoyancy can be made small.

By the structure of the floating body 20 described above, the present invention has the advantage that the buoyancy of the floating body 20 can be adjusted according to the weight applied to the floating body 20.

An example of the movement limiting unit for limiting the movement of the floating body 20 to a predetermined range of the water surface is a first rope 53 connected to the first ring 51 formed on the floating body 20 and extending to the bottom of the water body. ) And a fixture 55 for fixing the first rope 53. The fixture 55 is connected to the first rope 53 and uses a weight 55 or an anchor fixed to the bottom of the body of water. The second ring 57 is connected to the second ring 57 provided on both sides of the floating body 20 so as to be connected to a support (not shown) installed on the ground of the waterside.

The aeration unit is for supplying air into the water, and in the illustrated example, a blower 31, an exhaust line 33 connected to the blower 31, extending in the water and conveying air discharged from the blower, and an exhaust line ( And an diffuser 35 connected to 33 to inject air into the water.

 A blower 31 is installed on top of the housing 21. The blower 31 is driven by electricity supplied from the power supply unit. An oxygen generator may be installed instead of the blower 31 to generate oxygen.

The exhaust line 33 is connected to the discharge port side of the blower 31 extends underwater. The exhaust line 33 may use a metal pipe or a flexible hose. The exhaust line 33 may extend through the floating body 20 or extend out of the floating body 20. The exhaust line 33 is branched in both the left and right directions is coupled to the T-type socket 34 in the middle. At the end of the exhaust line 33, a conventional diffuser 35 is connected.

The diffuser 35 has a plurality of holes through which air is injected, and air is injected at a constant pressure to form bubbles in the water. Bubbles generated in water not only increase the amount of dissolved oxygen in the water, but also bring about the effect of improving the water quality by oxidizing pollutants in the water. In addition, the bubbles rise to the surface to form an upward flow. This upward flow has the effect of circulating the water in the closed water up and down.

A secondary battery such as a storage battery is used as a power supply unit for supplying power to the blower 31. The battery (not shown) charges electricity generated by the self-generating unit 940. In the example shown, the storage battery is installed inside the control box 15. The control box 15 installed on the upper portion of the floating body is provided with a known controller, an operation unit, various electric circuits, a display, and the like for operating the blower.

Self-generating unit 40 for generating a battery by solar light or wind power is provided with a support frame installed in the floating body 20, and a photovoltaic module 47 supported by the support frame, for example. The support frame is composed of a support (41) extending upwardly from the floating body (20) formed at a predetermined height, and a fixed plate (45) rotatably coupled to an upper part of the support (41) to be rotated up and down. The lower portion of the support 41 is formed with a flange fixed to the housing. The pillar 41 is preferably a hollow square tube structure is applied. Of course, the fixed plate 45 in which the photovoltaic module 47 is installed may be installed to rotate left and right in addition to the top and bottom. In addition, a tracking device may be provided that is electronically controlled so that the stationary plate 45 can follow the sun.

The photovoltaic module 47 is arranged on the fixed plate 45 by arranging a plurality of solar cells in a lattice form. The electricity generated by the photovoltaic module 47 is charged in the storage battery. A voltage regulator (not shown) is installed between the photovoltaic module 47 and the storage battery so as to control the current so that the voltage generated in the photovoltaic module is kept constant and transferred to the storage battery.

The above-described self-generating unit 40 generates electricity by using sunlight and uses the generated electricity as a driving power source of the blower 31. Therefore, the present invention can drive the blower 31 by self-generation without a separate commercial power source. In addition, photovoltaic power generation does not harm or pollute nature and thus provides electricity in an environmentally friendly manner.

Meanwhile, as shown in FIG. 4, the self-generating unit may have a hybrid self-generating configuration capable of performing wind power generation together with the solar power generation. The self-generating unit is configured for the wind power generation and the rotational force from the rotating shaft 61 of the windmill 60 and the windmill rotated by the wind together with the above-described support frame 41, 45 and the photovoltaic module 47. It further includes a power generation unit 67 to receive and generate.

The windmill 60 rotates the blade 63 by natural wind, and converts it into electrical power by rotating the generator by increasing the speed using a gear mechanism or the like. An example of the windmill 60 shows a horizontal shaft windmill in which the rotating shaft 61 is horizontal with respect to the wind. That is, a post 69 extending upwardly from the housing 21 by a predetermined height is provided, and a power generation unit 67 is installed above the post 69. The rotating shaft 61 is rotatably supported by the power generation unit 67 as a windmill, and a plurality of blades 63 radially coupled to an end of the rotating shaft 61. As the rotating shaft 61 rotates by the rotation of the blade 63, the power generation unit 67 converts the kinetic energy of the rotating shaft into electrical energy. Although not shown, the power generation unit 67 is installed in the case and consists of a rotor and a power generation coil coupled to the rotation shaft 61. When the rotor is rotated, the induced electromotive force is generated by the electromagnetic induction in the power generation coil.

The above-described windmills are conventional, and various windmills may be installed in addition to the illustrated windmills. For example, a vertical windmill may be used in which the axis of rotation is perpendicular to the wind. The vertical axis windmill can use drag type that rotates the windmill by drag generated on the blade such as paddle type or savonius type, and lift type that rotates the blade by lifting force generated on the blade such as Darius type or Gyromill type. .

Self-power generation by solar and wind as described above can be generated by wind power even at night or cloudy weather can increase the operating efficiency of the water purification device. In addition, unlike the example of FIG. 4, the self-generating unit may be configured by wind power generation alone without solar power generation.

The bioreaction unit 70 is for decomposing various contaminants in the water, and the reaction chamber 71 in which the diffuser is mounted at the lower part, and the plurality of microorganisms inhabit by the flow of water inside the reaction chamber 71. Blocks the passage of the fluidized bed mediators 73 and the mediators 73 to limit the flow space of the mediators 73 but is installed in the reaction chamber 71 to allow water to pass therethrough, and a plurality of distribution holes ( 78 includes partition panels 77 and 79 formed therein.

The reaction chamber 71 is a biofilter having a biological filtration function, and decomposes various contaminants in water by the media 73 filled therein. The reaction chamber 71 is formed in a cylindrical shape in which the upper and lower sides are open. The reaction chamber 71 may be made of stainless steel, carbon steel, or the like. In the illustrated example, the reaction chamber 71 is composed of an upper body 71a and a lower body 71b which are mutually screwable. The reaction chamber 71 is coupled to the fixed bar 17 fixed to the floating body 20 and installed in water. The reaction chamber 71 may be installed at various depths. Preferably, the reaction chamber 71 may be configured to be movable up and down. This will be described in detail in the embodiment of FIG. 6 to be described later.

The partition panels 77 and 79 are installed at the upper and lower portions of the space in which the media 73 flows, respectively, to prevent the media 73 from flowing out of the reaction chamber 71. Therefore, the distribution holes 78 formed in the partition panels 77 and 79 are provided to have a smaller size than the size of the filter medium 73.

The fluidized bed medium 73 applied to the present invention is a microbial carrier and is introduced into the reaction chamber 71 to provide a habitat for the microorganisms so that the microorganisms grow and reproduce. In addition, the propagated microorganisms can decompose various organic substances contained in the water, pollutants such as ammonia, nitrous acid, nitric acid and nitrogen to purify the water quality.

Therefore, the surface area of the filter medium 73 must be large so that a large amount of microorganisms can be attached and multiply so as to secure a space for microorganisms, and flow in the reaction chamber 71 according to the flow of water so as not to sink to the bottom of the reaction chamber 71. You should be able to. The fluidized bed mediator 73 has a specific gravity of 0.2 to 0.6, and is formed in a structure having a large specific area of 2000 to 800 m 2 / m 3, thereby efficiently improving the surface area of the median 73. As an example of the media, a circular tubular body of a flexible material having a hollow portion therein, and a plurality of fins 73b are radially formed to increase the surface area on the outer circumferential surface of the tubular body.

 Microorganisms fixed to the filter medium 73 may be used in various ways depending on the type of contaminants to be decomposed. For example, Vorticela, Aspidisca and Rotaria, Euplotes, Amphileptus and the like can be used as microorganisms. As a fixing method, a known fixing method can be used. For example, the medium is immersed in a microbial culture and fixed at 30 ° C.

In addition to the above-described structure, it is a matter of course that a conventional microbial carrier can be used as a medium.

When the air supplied from the blower 31 is supplied to the diffuser 35 through the exhaust line 33, bubbles rise to the inside of the reaction chamber 71 to form an upward water flow. At this time, the filter medium 73 flows inside the reaction chamber 71, and the microorganisms attached to the filter medium 73 are supplied with oxygen. Therefore, the medium 73 does not stay in a specific position inside the reaction chamber 71, but flows through the reaction chamber 71 by the formation of a water flow due to the aeration of the diffuser 35, so that microorganisms efficiently remove contaminants. Allow disassembly. The epidermal layer of the microbial membrane attached to the surface of the filter medium 73 is contacted with air to decompose nitrite by aerobic microorganisms, which leads to nitrification. Denitrification reaction occurs to decompose contaminants.

In addition, the upward flow formed by the bubbles injected from the diffuser 35 has an effect of circulating the water in the lower layer to the upper layer while rising along the flow path formed by the reaction chamber 71. That is, upward flow is generated upward from the inside of the reaction chamber 71 by the flow of water, and water located below the reaction chamber 71 is moved upward through the reaction chamber 71 by the upward flow. Circulated to the surface layer. In this case, the water in the lower layer is mixed with the surface layer, and oxygen is dissolved in the water, and the organic material contained in the water in the lower layer is oxidized to improve the water quality.

Figure 5 shows the main part of the water purification device according to another embodiment of the present invention. 5, the water purification apparatus of the present invention further includes elevating means for moving the reaction chamber 91 up and down in water.

The lifting means includes a support bar 81, a drive motor 83, a lead screw 85, a guide bar 87, a slider 95, and a base bar 89.

One end of the support bar 81 is coupled to the housing 21 of the floating body. Preferably the floating body is coupled to the upper side of the housing 21 which is exposed above the water surface when installed in the appeal. The coupling can be joined by welding or bolts. The support bar 81 coupled to the housing 21 extends horizontally in the outward direction of the float. The support bar 81 is spaced apart from the water surface by a predetermined distance. At the end of the support bar 81 is formed a second ring 57 to which the second rope 89 is coupled.

A drive motor 83 is installed at the support bar 81. Although not shown, the driving motor is electrically connected to the power supply unit, that is, a battery in which electricity generated in the self-generating unit is charged. Therefore, the electricity for driving the drive motor 83 is supplied from the storage battery. The power supply to the driving motor 83 can be controlled by the controller of the control box described above according to the set program. In addition, a lead screw 85 is connected to the drive motor 83. The lead screw 85 may be directly connected to the drive shaft of the drive motor 83 or coupled to a gear.

The lead screw 85 extends a certain length vertically downward. The lead screw 85 extends from the surface to the depth of a certain depth. The lead screw 85 has a circular rod shape and a thread is formed on the outer surface. The lead screw 85 is screwed to the coupling portion 93 formed on one side of the reaction chamber 91. Coupling portion 93 is provided with a screw hole (not shown) formed on the inner peripheral surface of the screw thread corresponding to the screw thread formed on the lead screw (85). The screw hole is formed by penetrating the upper and lower sides of the coupling portion 93.

The guide bar 87 is installed in parallel with the lead screw 85. The upper end of the guide bar 87 is coupled to the support bar 81, and the lower end extends a predetermined length downward. The guide bar 87 is formed in a circular rod shape. The guide bar 87 and the lead screw 85 are formed to the same length. The base bar 89 is installed below the guide bar 87. Base bar 89 serves to support the lower end of the lead screw (85). A shaft support bearing unit 90 is installed on the base bar 89 that supports the lower end of the lead screw 85.

When power is applied to the drive motor 83 and the lead screw 85 rotates, the reaction chamber 91 moves up or down along the guide bar 87 according to the rotation direction of the lead screw 85. At this time, the exhaust pipe 33 is connected to the reaction chamber 91 is preferably formed of a flexible hose to facilitate the bending deformation. The exhaust pipe 33 secures the length so that the reaction chamber 91 is more relaxed than the distance of the reaction chamber 91 from the blower 31 when the reaction chamber 91 descends to the maximum.

Since the reaction chamber 91 can be moved up and down in this manner, the reaction chamber 91 can be disposed at an appropriate depth in the closed water to decompose contaminants. In addition, since an upward flow is formed in the reaction chamber 91, the reaction chamber 91 may be disposed in various depth layers to circulate water around the reaction chamber 91.

In addition, while lifting and winding the wire rope connected to the reaction chamber using a driving motor as the lifting means, the reaction chamber can be lifted up and down. At this time, the reaction chamber is guided up and down by the guide bar.

On the other hand, the components not described in Figures 4 and 5 are the same as the embodiment shown in Figures 1 to 3 and thus will not be described in detail.
