Description
Technical Field
The present invention relates to a water treatment facility, and more particularly, to a water treatment facility capable of preventing contaminants from adhering to a mesh filter for filtering contaminants contained in water during a water treatment process.
Background
The various contaminants that we generate around can be divided into point contaminants and non-point contaminants. The point contaminants are contaminants discharged from point pollution sources, which are specific and limited, such as domestic sewage or industrial wastewater generated in general households or factories. Non-point pollutants are pollutants that are produced in non-specific and extensive areas such as farmlands, pastures, woodlands or roads.
Non-point contaminants include, for example, fertilizers or pesticides sprayed on agricultural fields, effluents from livestock pens, dust, heavy metals, pathogenic microorganisms, organic compounds, and radioactive materials. Non-point contaminants in the form of dust or waste are washed by incipient rain and flow into nearby rivers or groundwater. Therefore, it is very important to prevent the initial rainwater from directly flowing to the river or the groundwater.
In order to remove non-point contaminants from the initial rainwater, a rainwater infiltration facility, a dual-purpose detention pond, a pond, an artificial wetland, a filtering facility, an oil-water separation system, and a filtering system are constructed, thereby preventing the natural stream and the nearby sea area from being polluted by the initial rainwater containing contaminants.
However, in most cases, the amount of incipient rain that can be treated by the above-mentioned facilities is limited. Therefore, the pollutants contained in the initial rainwater are not sufficiently removed and flow to the natural stream and the nearby sea area. That is, the facilities in the related art are limited in their ability to effectively prevent environmental pollution. Therefore, there is a need to effectively remove contaminants through facilities such as water treatment facilities.
Since the non-point source contaminant is present in the rainwater at a high concentration, the contaminant may be adhered to a filter for filtering the contaminant, the movement speed of the rainwater is reduced due to the occurrence of the fouling phenomenon, or the filtering performance of the filter is deteriorated. Therefore, there is a need for a water treatment facility that can prevent contaminants from adhering to the filter and thus prevent rainwater from moving poorly in the filter or shortening the service life of the filter.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 and 2 illustrate a water treatment facility 10 according to the present invention.
A water treatment facility 10 according to an embodiment of the present invention includes a central portion 20 configured to allow water to be introduced into the central portion and to flow outwardly therefrom in a radial direction, first micro mesh filter units installed along a circumference of the central portion 20 to primarily remove contaminants contained in the water, second micro mesh filter units installed around the first micro mesh filter units 21 while being spaced apart from the first micro mesh filter units 21 in a radial direction to secondarily remove contaminants contained in the water, and a ring-shaped first vibration member 32 installed on a bottom of a space defined between the first micro mesh filter units 21 and the second micro mesh filter units 31 to vibrate the water. The vibration of the first vibration member 32 prevents contaminants from adhering to the second microfilter unit 31.
The water treatment facility 10 according to the embodiment of the present invention further includes a curtain filter unit 21 installed in the central portion 20 and formed in the shape of a cylinder having a predetermined thickness and in which fiber media are filled, and an annular second vibration member 23 installed on the bottom of the space defined between the curtain filter unit 22 and the first micro mesh filter unit 21 to vibrate water. The vibration of the second vibration member 23 prevents contaminants of the central portion 20 from adhering to the first microfilter unit 21.
The present invention provides a water treatment facility for treating water containing contaminants (e.g., rainwater containing non-point source contaminants). The water treatment facility 10 is formed in a radial shape such that rainwater introduced into the central portion 20 of the water treatment facility 10 flows outward in a radial direction. As described above, the water treatment facility 10 of the present invention includes the center portion 20, the first micro mesh filter unit 21, the second micro mesh filter unit 31, the first vibration member 32, the curtain filter unit 22, and the second vibration member 23. Referring to fig. 2, water to be treated is introduced into the central portion 20 via the inlet conduit 11 and flows outwardly in a radial direction via the curtain filter unit 22, the first microfilter unit 21 and the second microfilter unit 31 in sequence.
In fig. 2, the portion located radially inside the first microfilter unit 21 is referred to as a central portion 20, and the portion located radially outside the first microfilter unit 21 is referred to as a peripheral portion 30. A curtain filter unit 22 is mounted in the central portion 20. The water to be treated is first filtered by the curtain filter unit 22. As shown in fig. 1, the curtain filter unit 22 is formed in the shape of a cylinder having a predetermined thickness and filled with a fiber medium. The fiber media of the curtain filter unit 22 are formed in a multi-layered structure composed of low-density fiber media, medium-density fiber media, and high-density fiber media, which are disposed to move outward in sequence while being spaced apart from each other.
A first microfilter unit 21 is mounted along the periphery of the central portion 20. The first micro mesh filter unit 21 has pores smaller than the pores in the curtain filter unit 22. The first micro mesh filter unit 21 filters contaminants passing through the curtain filter unit 22 while allowing water to pass therethrough.
The second microfilter unit 31 is mounted around the first microfilter unit 21 while being spaced from the first microfilter unit 21 in a radial direction. The second microfilter unit 31 has a more compact structure than the first microfilter unit 21. Therefore, the second microfilter unit 31 is able to filter contaminants having smaller particles than the curtain filter unit 22 and the first microfilter unit 21. Although the present invention is illustrated in fig. 1 and 2 as including two micro mesh filter units, the present invention is not so limited. A greater number of micro mesh filter units may be provided in the perimeter portion 30.
The first vibration member 32 is installed on the bottom of the peripheral portion 30, which is a space defined between the first and second microfilter units 21 and 31. The first vibration member 32 has a ring-shaped structure to be mounted on the bottom of the peripheral portion 30. The first vibration member 32 serves to vibrate the water. The method of vibrating the water by the first vibration member 32 is not limited to a specific method. The first vibration member 32 may use an ultrasonic vibration method to vibrate the water. The speed of movement of the water in the vicinity of the microfilter units 21 and 31 is low, for example in the range of 2 to 6 mm/s. Due to the low speed of movement of the water, the adhesion of contaminants to the microfilter units 21 and 31 is low. According to the present invention, the contamination can be prevented from being easily adhered to the micro mesh filter units 21 and 31 using the ultrasonic vibration method. Specifically, the vibration of the first vibration member 32 causes contaminants to repeatedly attach to and detach from the second microfilter unit 31, thereby preventing contaminants from becoming trapped or bound to the pores in the second microfilter unit 31.
The second vibration member 23 is installed on the bottom of the space defined between the curtain filter unit 22 and the first micro mesh filter unit 21. The second vibration member 23 also serves to vibrate the water. The second vibration member 23 may use an ultrasonic vibration method to vibrate the water. The vibration of the second vibration member 23 causes contaminants that move from the curtain filter unit 22 to the first microfilter unit 21 to repeatedly attach to and detach from the first microfilter unit 21, thereby preventing the contaminants from becoming trapped or bound in the pores in the first microfilter unit 21.
Since the contaminants are separated from the microfilter units 21 and 31 by the first and second vibration members 32 and 23, the contaminant filtering performance of the microfilter units 21 and 31 is improved. Furthermore, the degree of adhesion of contaminants to the microfilter units 21 and 31 is greatly reduced and the service life of the microfilter units 21 and 31 is thereby increased.
Because the pores in the second microfilter unit 31 are smaller than the pores in the first microfilter unit 21, contaminants are more likely to bind to the second microfilter unit 31 than to the first microfilter unit 21. Therefore, the first vibration member 32 may be provided to generate a larger vibration than the second vibration member 23.
Further, the first vibration member 32 may be formed in close contact with the second micro mesh filter unit 31. In a similar manner, the second vibration means 23 may be formed in close contact with the first microfilter unit 21. With this configuration, the purpose of vibrating the water, i.e., preventing contaminants from adhering to the first and second microfilter units 21 and 31, may be accomplished by vibrating the water at a location proximate to the first and second microfilter units 21 and 31.
Fig. 3 and 4 illustrate the third vibration member 21a and the fourth vibration member 31a of the present invention.
In a water treatment facility 10 according to an embodiment of the invention, the first microfilter unit 21 comprises a first mesh filter 21c and a first external frame 21b surrounding the first mesh filter 21c, and the second microfilter unit 31 comprises a second mesh filter 31c and a second external frame 31b surrounding the second mesh filter 31 c. The water treatment facility 10 may further include a third vibration means 21a mounted on the first outer frame 21b of the first microfilter unit 21 to vibrate the first microfilter unit 21, and a fourth vibration means 31a mounted on the second outer frame 31b of the second microfilter unit 31 to vibrate the second microfilter unit 31.
The third 21a and fourth 31a vibrating members serve as means for detaching contaminants from the microfilter unit. Specifically, while the first and second vibration members 32 and 23 vibrate the water to detach the contaminants from the microfilter unit, the third and fourth vibration members 21a and 32a directly vibrate the microfilter unit to detach the contaminants from the microfilter unit. In order to easily vibrate the first and second microfilter units 21 and 31, the means for vibrating these microfilter units needs to be located outside the water, rather than in the water. The reason for this is that if the vibration device is located in water, the water absorbs the vibrations. Therefore, the third vibration member 21a and the fourth vibration member 31a are installed on the first micro filter unit 21 and the second micro filter unit 31, respectively. In the first microfilter unit 21, a first mesh filter 21c is supported by a first external frame 21 b. Similarly, in the second microfilter unit 31, a second mesh filter 31c is supported by a second outer frame 31 b. The third and fourth vibration members 21a and 31a are installed on the outer frames 21b and 31b of the micro mesh filter units 21 and 31, respectively, to directly vibrate the outer frames 21b and 31 b. Accordingly, the vibrations of the third vibration member 21a and the fourth vibration member 31a are transmitted to the mesh filters 21c and 31c via the external frames 21b and 31b, whereby the entire micro mesh filter unit 21 and 31 shakes. Thereby, the adhesion of the contaminants to the micro mesh filter units 21 and 31 is prevented by shaking the micro mesh filter units 21 and 31.
Fig. 4 illustrates a bubble generating apparatus according to another embodiment of the present invention.
A water treatment facility 10 according to another embodiment of the present invention comprises a central portion 20, a first microfilter unit 21, a second microfilter unit 31 and a first air bubble generating means 33, the central portion is configured to allow water to be introduced into the central portion and flow outwardly therefrom in a radial direction, the first micro-mesh filter unit is installed along the circumference of the central portion 20, to primarily remove contaminants contained in the water, the second microfilter unit is installed around the first microfilter unit 21 while being spaced apart from the first microfilter unit 21 in a radial direction, to secondarily remove contaminants contained in the water, and the first bubble generating means is installed on the bottom of the peripheral portion 30, to generate bubbles in the water, the perimeter portion is the space defined between the first microfilter unit 21 and the second microfilter unit 31. The bubbles generated by the first bubble generating device 33 rise and thereby prevent the contaminants in the perimeter portion 30 from attaching to the second microfilter unit 31.
The water treatment facility 10 according to another embodiment of the present invention further includes a curtain filter unit 22 installed in the central portion 20 and formed in the shape of a cylinder having a predetermined thickness and in which fiber media are filled, and a second air bubble generating means 24 installed on the bottom of the space defined between the curtain filter unit 22 and the first micro mesh filter unit 21 to generate air bubbles in the water. The bubbles generated by the second bubble generating means 24 rise and thereby prevent the contaminants in the central portion 20 from adhering to the first microfilter unit 21.
As described above, the water treatment facility 10 according to another embodiment of the present invention includes the first bubble-generating device 33 and the second bubble-generating device 24. The first effect obtained by generating bubbles using the bubble generating means 33 and 24 is to generate vibration in water. Similar to the first and second vibration members 32 and 23, the bubble generating devices 33 and 24 also apply vibration to the water, thereby preventing contaminants from adhering to the microfilter units 21 and 31. A second effect obtained by generating bubbles using the bubble generating means 33 and 24 is to push or vibrate the contaminants due to the pressure of the bubbles to thereby prevent the contaminants from adhering to the microfilter units 21 and 31. As shown in fig. 4, the bubbles generated by the bubble generating devices 33 and 24 gradually expand while rising, and thus cause the contaminants contained in the water in the peripheral portion 30 to vibrate or move. Since the bubbles gradually expand while rising, the contaminants may be moved by the pressure of the bubbles.
When the contaminants in the water are attached to the second microfilter unit 31, the contaminants are vibrated by the bubbles generated by the first bubble generating means 33 and thus detached from the second microfilter unit 31. In this way, contaminants are prevented from adhering to the second microfilter unit 31. Further, the bubbles generated by the second bubble generating means 24 gradually expand while rising, and thus cause the contaminants contained in the water in the central portion 20 to vibrate or move. Thus, when contaminants in the water attach to the first microfilter unit 21, the contaminants are vibrated by the air bubbles and thereby detach from the first microfilter unit 21. In this way, contaminants are prevented from adhering to the first microfilter unit 21.
As is apparent from the above description, for example, according to the water treatment facility of the present invention, water is vibrated so that contaminants contained in the water are detached from the filter immediately after the contaminants are attached to the filter. Thus, contaminants are prevented from adhering to the filter of the water treatment facility of the present invention.
Further, according to the water treatment facility of the present invention, air bubbles are generated in rainwater by the air bubble generating means to promote movement of contaminants contained in the rainwater, thereby preventing the contaminants from sticking to the filter.
Although the present invention has been described in detail with reference to particular embodiments, those embodiments are provided for illustrative purposes only. Accordingly, the present invention is not limited to those embodiments, but those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
Further, simple changes and modifications of the present invention should be understood to be included in the scope and spirit of the present invention, and the scope of protection of the present invention should be defined by the appended claims.
