Description

Water Treatment Facility {WATER TREATMENT FACILITY}

The present invention relates to a water treatment facility, and more particularly, to a water treatment facility that prevents contaminants from adhering to a mesh filter that filters contaminants in water during water treatment.

The various pollutants that occur around us can be divided into point pollutants and non-point pollutants. The point pollutant is a pollutant discharged from a so-called point pollutant with a clear and limited generation point, such as domestic sewage or industrial wastewater generated in a general home or factory. In addition, non-point contaminants are pollutants that occur in a wide range of areas, where no contaminated areas such as agricultural lands, pastures, forests, or roads are established.

The non-point contaminants include, for example, fertilizer or pesticide sprayed on farmland, barn spillage, dust and heavy metals, pathogenic microorganisms, organic compounds, radioactive materials, etc. Washed in rain water and flows into nearby rivers or groundwater. Therefore, it is very important to prevent the initial stormwater from flowing directly into the river or groundwater.

In order to remove non-point contaminants from the initial rainwater, excellent infiltration facilities, dual-purpose reservoirs, ponds, artificial wetlands, filtration facilities, oil-water separation devices, and filter devices are installed, and natural rivers and nearby areas due to initial rainwater containing pollutants It prevents water pollution in the sea area.

However, most of the facilities mentioned above do not remove pollutants contained in the initial well because they have a limited amount of treatment to treat the initial good, and they effectively circulate in natural rivers and nearby waters, effectively preventing environmental pollution. There are limitations. Therefore, it is necessary to effectively remove contaminants through facilities such as water treatment facilities.

Since rainwater has a high concentration of pollutants such as a non-point source, there is a problem that pollutants adhere to a filter for filtering pollutants or a fouling phenomenon occurs, thereby slowing the speed of movement of rainwater or deteriorating the filtering performance of the filter. Therefore, there is a need for a water treatment facility to solve the problem of contaminants adhering to the filter, preventing the movement of rainwater or shortening the life of the filter.

1 and 2 show a water treatment facility 10 of the present invention.

The water treatment facility 10 according to an embodiment of the present invention is installed around the central portion 20 to allow water to enter and flow in the radial direction, and is installed around the radial direction based on the central portion 20 to remove pollutants in the water. A first fine filter (21) for primary removal, a second fine mesh filter (31) installed on the radially outer periphery of the first fine mesh filter portion (21) to secondaryly remove contaminants in water, and It is installed on the bottom of the space between the first fine mesh filter portion 21 and the second fine mesh filter portion 31 includes an annular first vibrating member 32 for vibrating water, and the first vibrating member It prevents the contaminants from sticking to the second fine mesh filter unit 31 through the vibration of (32).

In a water treatment facility 10 according to an embodiment of the present invention, the first vibrating member 32 is installed in the central portion 20, takes the form of a cylinder having a certain thickness, and is filtered with a fibrous filter material. The filter unit 22 and the curtain filtration filter unit 22 and the first fine mesh filter unit 21 is installed on the bottom of the space further comprises an annular second vibration member 23 for vibrating water, It prevents the contaminants of the central portion 20 from adhering to the first fine mesh filter unit 21 through the vibration of the second vibration member 23.

The present invention is a facility for treating water with contaminants (for example, rainwater with a non-point source). The water treatment facility 10 is formed in a radial shape, and rainwater enters the central portion 20 of the water treatment facility 10 and flows in a radial direction. The water treatment facility 10 of the present invention includes a central portion 20, a first fine mesh filter portion 21, a second fine mesh filter portion 31, a first vibration member 32, a curtain filtration filter portion 22, It includes a second vibration member (23). Referring to FIG. 2, the water to be subjected to water treatment enters the central portion 20 along the inflow pipe 11, and the curtain filtration filter unit 22, the first fine mesh filter unit 21, and the second fine mesh filter unit 31 It flows in the radial direction as it passes through in order.

Referring to FIG. 2, the present invention is referred to as a central portion 20 in the radial direction and an outer portion 30 in the radial direction based on the first fine mesh filter portion 21. The curtain filtration filter unit 22 is installed in the central portion 20. In the curtain filtration filter unit 22, water to be treated is filtered first. Referring to FIG. 1, the curtain filtration filter 22 takes the form of a cylinder having a certain thickness and is filled with fibrous media. The fibrous filter media of the curtain filter unit 22 is arranged in multiple layers so that the low-density fibrous filter media, the medium-density fiber filter media, and the high-density fiber filter media are spaced apart from each other.

The first fine mesh filter unit 21 is installed around the radial direction with respect to the central portion 20. The first fine mesh filter part 21 is a filter member having a smaller pore than the curtain filtration filter part 22. The first fine mesh filter unit 21 filters out contaminants that have passed through the curtain filter unit 22 and allows water to pass through.

The second fine mesh filter unit 31 is installed in the radially outer periphery of the first fine mesh filter unit 21. The second fine mesh filter unit 31 has a denser structure than the first fine mesh filter unit 21. Therefore, the second fine mesh filter unit 31 can filter out contaminants of smaller particles than the curtain filtration filter unit 22 and the first fine mesh filter unit 21. 1 and 2 of the present invention, only two fine mesh filters are illustrated, but the present invention is not limited thereto, and more fine mesh filter parts may be disposed in the outer part 30.

A first vibrating member 32 is installed on the bottom of the outer portion 30 which is a space between the first fine mesh filter portion 21 and the second fine mesh filter portion 31. Since the first vibrating member 32 is formed on the bottom of the outer portion 30, it has an annular structure. The first vibrating member 32 vibrates water. The method in which the first vibrating member 32 vibrates water is not limited, but the ultrasonic vibrating method can vibrate the water. The movement speed of water in the vicinity of the fine mesh filter portions 21 and 31 is small enough to be formed at 2 to 6 mm/s. In the case of the present invention, since the moving speed of water is small and the adsorption power of contaminants coupled to the fine mesh filter parts 21 and 31 is weak, contaminants are easily adsorbed to the fine mesh filter parts 21 and 31 through ultrasonic vibration. Can be prevented. Contaminants are prevented from sticking or sticking to the pores of the second fine mesh filter unit 31 by repeatedly dropping the contaminants to and from the second micro mesh filter unit 31 by the first vibrating member 32. .

The second vibrating member 23 is installed on the floor of the space between the curtain filtration filter 22 and the first fine mesh filter 21. The second vibrating member 23 also vibrates water, and an ultrasonic vibration method may be used as the vibration method of water. By the vibration of the second vibrating member 23, the contaminants moving in the direction of the first micromesh filter unit from the curtain filtration filter unit 22 have been repeatedly dropped and contacted by the first micromesh filter unit 21. 1 The contaminants do not get stuck or adhere to the pores of the fine mesh filter unit 21.

As the contaminants are separated from the fine mesh filter parts 21 and 31 by the first vibrating member 32 and the second vibrating member 23, the contaminant filter function of the fine mesh filter parts 21 and 31 is improved. . In addition, as the degree to which contaminants adhere to the fine mesh filter units 21 and 31 is significantly reduced, the usable time of the fine mesh filter units 21 and 31 increases.

Since the pores of the second fine mesh filter portion 31 are formed smaller than the pores of the first fine mesh filter portion 21, there is a possibility that contaminants adhere to the second fine mesh than the first fine mesh filter portion 21. It becomes higher in the filter part 31. Therefore, the vibration of the first vibration member 32 can be set stronger than the vibration of the second vibration member 23.

In addition, the first vibration member 32 may be formed in close contact with the second fine mesh filter unit 31. Similarly, the second vibrating member 23 may also be formed in close contact with the first fine mesh filter unit 21. Since the purpose of vibrating water is to prevent contaminants from adhering to the first fine mesh filter part 21 and the second fine mesh filter part 31, the vibration of water is closest to the fine mesh filter parts 21 and 31. It is intended to be formed.

3 and 4 show the third vibrating member 21a and the fourth vibrating member 31a of the present invention.

In the water treatment facility 10 according to an embodiment of the present invention, the first fine mesh filter unit 21 includes a first outer frame surrounding the first mesh filter 21c and the first mesh filter 21c ( 21b), the second fine mesh filter unit 31 is composed of a second mesh filter 31c and a second outer frame 31b surrounding the second mesh filter 31c, and the water treatment facility (10) is installed on the first outer frame 21b of the first fine mesh filter unit 21, a third vibrating member 21a for vibrating the first fine mesh filter unit 21 and the agent 2 further includes a fourth vibrating member 31a installed on the second outer frame 31b of the fine mesh filter unit 31 to vibrate the second fine mesh filter unit 31.

As a means for separating the fine mesh filter and the contaminants, the third vibrating member 21a and the fourth vibrating member 31a may be further included. The first vibrating member 32 and the second vibrating member 23 separated the contaminants from the fine mesh filter by vibrating water. In contrast, the third vibrating member 21a and the fourth vibrating member 31a directly vibrate the fine mesh filter to separate contaminants from the fine mesh filter. In order to easily vibrate the first fine mesh filter part 21 and the second fine mesh filter part 31, means for vibrating should be disposed outside the water, not in the water. This is because water will absorb vibrations if a means to vibrate is located in the water. Accordingly, the third vibrating member 21a and the fourth vibrating member 31a are respectively installed on the first fine mesh filter part 21 and the second fine mesh filter part 31. The first fine mesh filter unit 21 and the second fine mesh filter unit 31 of the present invention are composed of mesh filters 21c and 31c between the outer frames 21b and 31b and the outer frames 21b and 31b. do. Therefore, the third vibrating member 21a and the fourth vibrating member 31a are installed on the outer frames 21b and 31b of the fine mesh filter parts 21 and 31 to directly vibrate the outer frames 21b and 31b. . Therefore, the vibrations are transmitted from the outer frames 21b and 31b to the mesh filters 21c and 31c, thereby causing the fine mesh filter parts 21 and 31 to shake as a whole. Due to the phenomenon that the fine mesh filter parts 21 and 31 are shaken, contaminants cannot be adhered to the fine mesh filter parts 21 and 31.

Figure 4 shows a bubble generating device according to another embodiment of the present invention.

In the water treatment facility 10 according to another embodiment of the present invention, water enters the central portion 20 and flows in a radial direction, and is installed around the radial direction based on the central portion 20 to control pollutants in the water. The first fine mesh filter unit 21 to be removed by car, the second fine mesh filter unit 31 is installed on the radially outer periphery of the first fine mesh filter unit 21 to secondaryly remove contaminants in the water. And a first bubble generating device 33 installed on the bottom of the outer portion 30 which is a space between the first fine mesh filter portion 21 and the second fine mesh filter portion 31 to generate bubbles in the water. Including, while the bubbles generated by the first bubble generating device 33 rises, it prevents contaminants of the outer portion 30 from contacting the second fine mesh filter portion 31.

The water treatment facility 10 according to another embodiment of the present invention is installed in the central portion 20, takes the form of a cylinder having a certain thickness and is filled with a fibrous filter material, the filter filter unit 22 and the filter filter filter A second bubble generating device 24 installed at the bottom of the space between the part 22 and the first fine mesh filter part 21 to generate bubbles in the water, and the second bubble generating device 24 It prevents the contaminants of the central portion 20 from adhering to the first fine mesh filter unit 21 as the bubbles generated by the rise.

In another embodiment of the present invention, the first bubble generating device 33 and the second bubble generating device 24 are included. The first effect of bubble generation is that bubbles are generated in the bubbles generating devices 33 and 24 to generate vibration in the water. Accordingly, the bubble generating devices 33 and 24 also apply vibration to the water, like the first and second vibrating members 32 and 23, so that contaminants do not adhere to the fine mesh filter parts 21 and 31. The second effect of the bubble generating devices 33 and 24 is that the pollutants are pushed or vibrated by the air pressure of the bubbles, so that the pollutants cannot adhere to the fine mesh filter parts 21 and 31. As shown in FIG. 4, the bubbles generated in the bubble generating devices 33 and 24 rise and gradually increase, thereby vibrating or moving contaminants in the water of the outer portion 30. Since the bubble increases as it rises, contaminants may be moved by air pressure.

When the contaminants in the water touch the second fine mesh filter unit 31, it is vibrated by the bubbles generated in the first bubble generating device 33 and separated from the second fine mesh filter unit 31, thereby contaminating the second contaminants. It prevents sticking to the fine mesh filter part (31). In addition, as the bubbles generated in the second bubble generating device 24 rise and gradually increase, the pollutants in the water of the central portion 20 are vibrated or moved. Therefore, when the contaminants in the water touch the first fine mesh filter unit 21 and vibrate by air bubbles to be separated from the first fine mesh filter unit 21, the contaminants adhere to the first fine mesh filter unit 21. Prevent things.
