Description

Variable overflow wear for water purification system with free control of discharge of sewage and water purification system equipped with same

The present invention relates to a water purification system, and in particular, it is possible to smoothly control the discharge amount of sewage overflowing according to the change in water quality and the amount of water treatment, even though it is based on natural flow discharge, so that more detailed and active treatment of sewage is possible. It relates to a variable overflowware for a water purification system capable of purification treatment and a water purification system having the same.

In general, a water purification system refers to a device that prevents environmental pollution by purifying and treating domestic sewage and wastewater, various industrial wastewater, and livestock wastewater.

This water purification system removes solid substances, organic substances, and nitrogen and phosphorus as major contaminants contained in sewage through step-by-step treatment. For example, in the first treatment step, suspended solids with good settling properties are physically removed, in the second treatment step, which is the main treatment step, dissolved organic matter and organic solids are treated, and in the third treatment step, physical, chemical, and biological treatment methods to remove organic matter and nutrients that were not removed in the secondary treatment.

Here, the most commonly used method for secondary biological treatment is the activated sludge method, and the organic matter removal rate aims at an average of 90%. However, the biological secondary treatment method that is normally operated also has limitations in treating pollutants, so the following tertiary treatment is required to maintain high quality treated water.

Depending on the material to be treated, the tertiary treatment of wastewater includes rapid sand filtration, flocculation sedimentation, and membrane separation for organic matter including suspended matter. denitrification is used. In the case of phosphorus, coagulation precipitation, other biological methods, biological nitrogen and phosphorus simultaneous removal methods, and more than one modification method are widely used.

Among them, the water purification system using the rapid filtration method is widely used because it has the advantage of obtaining relatively high-quality treated water, but there are difficulties in maintenance such as frequent backwashing. In particular, in the case of the traditional serial connection method in which wastewater is sequentially treated while moving sewage along the mixing tanks and sedimentation tanks arranged in a row, the treatment efficiency is low, and in the case of sedimentation tanks that require frequent maintenance such as backwashing, they are connected one-to-one in response to the mixing tank. As the volume increased, maintenance was difficult.

In addition, in the case of natural flow discharge in the water purification system according to the prior art, it was not easy to smoothly adjust the discharge amount of sewage in accordance with the change in water quality and the amount of water treatment, which lowered the efficiency of purification treatment for sewage. I had no choice but to.

<Example>

As shown in FIGS. 1 and 2, the water purification system according to an embodiment of the present invention controls the flow of sewage based on a natural flow method, and a plurality of sedimentation tanks 100B centered on a mixing tank 100A By simultaneously distributing sewage to a plurality of settling tanks 100B by means of a parallel connection structure disposed on both sides to perform multiple purification processes, efficiency of purification treatment is increased, while backwashing of the settling tank 100B, etc. This allows maintenance to be carried out more precisely and smoothly.

According to such a parallel connection structure, the sewage water flowing into the mixing tank 100A is simultaneously distributed to the plurality of sedimentation tanks 100B to be purified and discharged, thereby dramatically increasing the purification capacity. In addition, since the number and arrangement of the settling tanks 100B connected to the mixing tank 100A can be simply changed and constructed, it is possible to optimize the shape or size of the entire system according to local conditions.

For example, the ratio of settling tanks 100B centered on one mixing tank 100A can be expanded from 1:1 to 1:4, or even higher. Even if connected, two precipitation tanks 100B may be disposed only on one side of the mixing tank 100A, two precipitation tanks 100B may be disposed only on the other side of the mixing tank 100A, or one on both sides of the mixing tank 100A. this is possible In addition, it is possible to simply change and expand the scale of the entire system by arranging a plurality of systems centered on the mixing tank 100A. Here, a plurality of outlets 101a are formed side by side on the upper part of the wall 101 of the mixing tank 100A, and a settling tank 100B is disposed corresponding to the outlets 101a, thereby setting the settling tank 100B for the mixing tank 100A. ) can be expanded.

The water purification system according to an embodiment of the present invention is based on the natural flow method as described above and has an original layout of a parallel connection structure, and includes an aerator 110, a variable rectification module 130, and an equal flow distribution device 120. ), an overflow ware 140, a diffuser 150, a washing water spraying device 160, and a filter media cartridge 180M as main components.

Hereinafter, a water purification system according to an embodiment of the present invention will be described in detail, focusing on the main components.

The aerator 110 is installed at the bottom of the mixing tank 100A, and simultaneously ejects sludge for denitrification and air for generating aeration, and performs inflow of sewage, generation of aeration, and mixing at the same time.

To this end, the aerator 110, as shown in FIGS. 3 and 4, is branched in number along the outer circumferential surface of the outer main pipe 111 receiving sewage and the outer main pipe 111 to eject sewage into the mixing tank 100A. It is provided with an external blow-out pipe (111a) to eject sewage through a plurality of external blow-off pipes (111a). On the other hand, the inner main pipe 112 installed in the form of a double pipe along the inside of the outer main pipe 111 and receiving air for generating aeration, and a plurality of branches along the outer circumferential surface of the inner main pipe 112, but an external blowing pipe 111a It is branched in the form of a double pipe through the inside of the ) and is provided with an internal blowing pipe 112a for ejecting air for generating aeration to the mixing tank 100A.

According to the configuration of the aerator 110, the sludge for denitrification and the air for generating aeration are simultaneously ejected from the external blow-off pipe 111a and the inner blow-off pipe 112a having a double pipe structure, thereby simultaneously ejecting the sludge for denitrification and the air for generating aeration. In addition to supplying it, mixing of sewage can be done naturally.

The outer main pipe 111 and the inner main pipe 112 are formed in opposite directions of movement of sludge water and air, respectively, and each end is closed to remove sewage and Air is blown out strongly, and through this, even mixing is performed smoothly.

Here, as shown in FIG. 4, the external blowing pipe 111a and the internal blowing pipe 112a are inclined downward so that the sewage blowing direction and the air blowing direction are directed toward the bottom of the mixing tank 100A, respectively. Accordingly, it is possible to effectively suppress a phenomenon in which sludge rises due to the ejection of air for generating aeration. And, the end of the inner blow pipe 112a is formed longer than the end of the outer blow pipe 111a so as to protrude out of the outer blow pipe 111a. This prevents the internal blowing pipe 112a through which air is ejected from being clogged with sludge, and it becomes possible to smoothly eject both sludge and air.

As shown in FIGS. 1 and 2 , stirring blades 115 are further installed in the mixing tank 100A together with an aerator 110 . In this way, when the uniquely configured aerator 110 and the general stirring blades 115 are installed in the lower and upper parts of the mixing tank 100A, the sludge in the sewage supplied from various sources can be homogenized and the oxygen content can be uniformly distributed. there is. In addition, when chemicals are introduced for purification treatment of sewage, these chemicals can be rapidly and uniformly mixed. Therefore, it is not necessary to install an additional device to improve the denitrification effect by homogenizing the sludge and oxygen in the sewage.

The flow equalization distribution device 120 is installed on the wall of the mixing tank 100A and serves to control the flow of sewage by a natural flow method. To this end, the flow equalization distribution device 120 includes a guide body 121, opening and closing doors 122 and 123, and a drive motor 124 provided as a first actuator, as shown in FIGS. 5 and 6 .

The guide body 121 of the flow equalization distribution device 120 is installed in a U-shape along both sides and the lower circumference of the outlet 101a of the mixing tank 100A so that the opening and closing doors 122 and 123 can be rotated. While supporting, the flow of sewage is guided to the outlet 101a.

The lower end of the opening and closing doors 122 and 123 is hinged to the lower end of the guide body 121 and rotates around the lower hinge axis 122d to open and close the front opening of the guide body 121, and waste water according to the rotation angle. Since it is possible to adjust the water level at which the overflow of is made, it is possible to simply control the flow rate of sewage flowing out to the sedimentation tank 100B through the outlet 101a. That is, as shown in FIG. 7, in a state in which the opening and closing doors 122 and 123 are opened by rotating forward, even if the water level of the sewage is relatively low, the sewage actively overflows the opening and closing doors 122 and 123 and flows out to the outlet 101a, but in that state As shown in FIGS. 8 and 9 , as the opening and closing doors 122 and 123 rotate backward, the upper sides of the opening and closing doors 122 and 123 increase, and the amount of sewage overflow gradually decreases.

Here, the opening and closing doors 122 and 123 are hinged to the lower front part of the guide body 121 and rotate, and the front panel part 122 to adjust the flow rate of sewage flowing according to the rotation angle, and the front panel part ( 122) is formed at the side end portion of the front panel portion 122 to support the front panel portion 122 that rotates with respect to the guide body 121 while filling in the gap between the guide body 121 and the guide body 122 when the front panel portion 122 rotates. It consists of part 123. The upper side 122a of the front panel portion 122 of the opening and closing doors 122 and 123 prevents the sudden overflow of sewage and allows the overflow of sewage to start in small amounts at multiple points at the beginning of the overflow, thereby inducing a smooth flow of sewage. formed into a waveform. The side panel portion 123 is formed in a fan shape having gear teeth 123a at an upper arc, and is meshed with the gear teeth 123a of the side panel portion 123 in the guide body 121 to drive the drive motor 124. A gear assembly (not shown) providing driving force is installed.

A guide protrusion 123a is provided at the upper end of the outer surface of the side panel portion 123, and an arc-shaped guide protrusion 123a guides the movement of the guide protrusion 123a during rotation of the opening and closing doors 122 and 123 on the guide body 121. A guide groove 121a is formed. Thus, the rotational operation of the opening and closing doors 122 and 123 can be smoothly performed. Limit switches (not shown) are further installed at both ends of the guide groove 121a to sense the open/close state of the doors 122 and 123 by being switched by the guide protrusion 123a.

What can be noted in the configuration of the flow equalization distribution device 120 is that the opening and closing doors 122 and 123 are rotated by the driving force provided from the driving motor 124 provided as the first actuator to control the flow of sewage. However, unlike the general flow path opening and closing method, when the sewage rises in the mixing tank 100A and exceeds the set water level, the natural flow of the sewage flows through the front panel 122 of the opening and closing doors 122 and 123 and flows into the settling tank 100B. that the method is being followed. As such, since the flow equalization distribution device 120 is based on the natural flow method, there is little energy consumption for transporting sewage from the mixing tank 100A to the sedimentation tank 100B, and the natural flow of sewage is maintained throughout the system. water treatment takes place.

According to the configuration of the flow equal distribution device 120 for controlling the flow of sewage based on the natural flow method, it is very easy to control the flow of sewage according to the water quality information transmitted from each area of the water purification system. . To this end, the flow of sewage by the flow even distribution device 120 in consideration of the turbidity of the sewage flowing into the mixing tank 100A, the turbidity of the sewage at the top of the settling tank 100B, and the turbidity of the sewage discharged from the settling tank 100B. can be adjusted. In addition, the turbidity of the sludge discharged from the discharge groove (103b, see FIG. 10) formed at the lower front of the settling tank 110 is measured, and the turbidity of the measured sludge is also measured to measure up to the flow rate equal distribution device 120 The flow of sewage can be regulated.

To this end, a first turbidity measuring sensor for measuring the turbidity of sewage flowing into the mixing tank 100A, a second turbidity measuring sensor installed on the upper part of the settling tank 100B to measure the turbidity of sewage, and the settling tank ( 100B) is provided with a third turbidity measuring sensor for measuring the turbidity of the sludge discharged, and the first turbidity measuring sensor, the second turbidity measuring sensor, and the third turbidity measuring sensor measure the turbidity at each point.

The flow equalization distribution device 120 is installed in a number corresponding to the settling tank 100B connected to the mixing tank 100A. When the sedimentation tank 100B is connected side by side with respect to the mixing tank 100A, the flow equalization distribution device 120 is also installed side by side in the mixing tank 100A so as to operate individually.

On the other hand, the opening and closing doors 122 and 123 are configured to be manually rotated separately from the first actuator in addition to being automatically rotated by the first actuator providing driving force. Manual operation by such a manual operation is possible by simply using a lever or by operating a winch by connecting a wire to the opening and closing doors 122 and 123.

As shown in FIGS. 10 to 13 , the variable rectification module 130 is installed vertically so as to face and be spaced apart from the front wall where the outlet 101a is formed in the settling tank 100B, and flows into the settling tank 100B through the outlet 101a. It consists of a porous fixed rectifying wall 130A that filters out foreign substances from inflowing sewage, and a porous variable rectifying wall 130B installed so as to be able to move up and down while facing the fixed rectifying wall 130A in an overlapped state. The variable rectifying wall 130B moves up and down along the fixed rectifying wall 130A and adjusts the distribution amount of sewage according to the inflow height of the sewage passing through the fixed rectifying wall 130A.

Here, the first through hole 131 formed in the fixed rectifying wall 130A may have the same diameter at the top and bottom as shown in FIGS. 11 to 13, but preferably has a gradually larger diameter toward the bottom. The water pressure of sewage passing through the first through hole 131 of the fixed rectifying wall 130A can be equally adjusted. In addition, although not shown in the drawing, the first through hole 131 is formed to have a gradually larger diameter from the center of the fixed rectifying wall 130A toward the left and right sides, eliminating the deviation of the water pressure that changes toward the left and right sides and adjusting it equally. .

As shown in FIGS. 11 to 13 , the variable rectifying wall 130B has a narrower vertical width than the fixed rectifying wall 130A, and even in the case of the second through hole 132 formed in the variable rectifying wall 130B. It is formed to have a gradually larger diameter toward the lower side. However, as shown in FIG. 11, when the variable rectifying wall 130B is completely lowered, between the first through hole 131 and the second through hole 132 formed in the fixed rectifying wall 130A and the variable rectifying wall 130B, respectively. It is desirable to communicate with the size and position matched. According to this configuration, the variable rectifying wall 130B completely descends and aligns the first through hole 131 and the second through hole 132 so that they are in complete communication, so that sewage can freely pass through rather than filtering sludge, as shown in FIGS. 12 and 13 As shown in , the emphasis may be placed on filtering out the sludge while limiting the flow rate rather than freely passing the passing sewage by partially communicating the first through hole 131 and the second through hole 132.

Meanwhile, when the variable rectifying wall 130B descends, it is preferable that the lower end 133 protrudes more downward than the lower end of the fixed rectifying wall 130A so as to come into close contact with the bottom of the sedimentation tank 100B. Here, since the bottom of the settling tank 100B is formed in a cross-section with V-shaped valleys that deepen from both sides to the center to facilitate sludge washing and discharge, the lower end of the variable rectifying wall 130B is also of the settling tank 100B. Corresponding to the bottom, it is formed by forming a gentle triangular protrusion protruding downward from both sides toward the center.

According to the configuration of the variable rectification module 130 formed by combining the fixed rectifying wall 130A and the variable rectifying wall 130B as one, while adjusting the flow rate and flow rate of sewage passing through the fixed rectifying wall 130A by height, It is possible to properly control the inflow amount. This not only induces equal distribution of sewage in the upper, middle, and lower parts, but also blocks the inflow of sewage while the variable rectifying wall (130B) moves to the upper part depending on the situation, and allows the inflow of sewage in the middle to allow deviation. It is also possible to induce distribution. As such, in the case of the variable rectification module 130, the amount of sewage inflow can be adjusted according to the situation.

Here, a second actuator may be provided to provide a driving force so that the variable rectifying wall 130B moves up and down, so that the variable rectifying wall 130B automatically moves up and down by the driving force of the second actuator. At the same time, it is preferable that the variable rectifying wall 130B is configured to be manually selected to be moved up and down separately from the second actuator. The second actuator may be simply provided with a motor, a hydraulic cylinder, a wire, a winch, or the like, and in the case of manual operation, a lever or a winch may be used.

The overflow ware 140 is configured to naturally discharge the filthy water intermediately purified in the settling tank 100B by a natural flow method without consuming almost no energy. As shown in FIGS. 14 and 15 , the overflow weir 140 includes an overflow portion 143, a connection portion 144, a wear portion 142, and a porous partition wall 141.

In the overflow wear 140, the overflow part 143 is installed across the top of the sedimentation tank 100B in the transverse direction at a point spaced apart from the rear wall of the sedimentation tank 100B, and is formed in an open top surface. As a result, when the intermediately purified sewage in the settling tank 100B exceeds a certain water level, it flows through the upper side of the overflow part 143 and is introduced. The connection part 144 serves to connect the overflow part 143 and the outlet 102a to guide the wastewater flowing in through the overflow part 143 to be discharged through the outlet 102a. Sewage exceeding a certain water level is allowed to flow into the connection part 144 together with the overflow part 143 and then discharged through the discharge port 102a. In the configuration of the overflow ware 140 having the flow part 143 and the connection part 144, the overflow part 143 is not integrally provided on the rear wall 102 of the sedimentation tank 100B, but forward of the rear wall 102 It can be noted that it is provided at a spaced point. According to this configuration, as shown in FIG. 10, the overflow of the intermediately purified sewage in the settling tank 100B is carried out not only to the front side of the overflow part 143 but also to the rear side.

Furthermore, the overflow ware 140 further includes a porous partition wall 141 installed to transversely cross the inner space of the settling tank 100B along the overflow portion 143 from the lower side of the overflow portion 143. A plurality of through-holes 141a are formed in the porous barrier 141 to uniformly control the flow rate and flow rate of the sewage while passing the intermediately purified sewage. According to the configuration in which the porous partition wall 141 is installed below the overflow part 143, drift and shunt flow of the sewage flowing from the lower side of the overflow part 143 are suppressed and formed at the lower part of the rear end of the settling tank 100B. It will minimize the dead water area.

Here, in the porous partition wall 141, the through-holes 141a are not uniformly formed in the upper and lower regions, and the through-holes 141a differentiate the passage area of sewage in the upper and lower regions, or the upper and lower regions. It may be configured in a form in which the diameter of the through hole 141a is differentiated. In particular, as shown in the drawing, by concentrating through-holes 141a only in the lower region, the flow of sewage in the lower region is strengthened, thereby suppressing drift and shunt flow, and a dead water area formed below the rear end of the sedimentation tank 100B. The influence that minimizes can be further strengthened.

However, it goes without saying that the configuration of the porous partition wall 141 as described above may be performed in a direction of controlling the flow of sewage to be uniform and smooth in consideration of various environments created inside the settling tank 100B.

The overflow wear 140 extends from the overflow portion 143 in a forward protruding shape and further includes a wear portion 142 composed of a fixed wear 142a and a variable wear 142b. The upper surfaces of the fixed wear 142a and the variable wear 142b are open and are not significantly different from the overflow portion 143 or the connection portion 144 described above in form. However, the wear part 142 has a form extending forward from the overflow part 143 and is configured to adjust the overflow amount and residence time of the intermediately purified sewage inside the settling tank 100B.

In addition, since the variable weir 142b is configured to allow an upward tilting operation with respect to the fixed weir 142a, it is also possible to actively adjust the overflow amount of sewage. That is, as shown in FIGS. 15 to 17, the wear portion 142 includes a fixed wear 142a extending from the overflow portion 143 and a variable wear coupled to be tiltable upward at the front end of the fixed wear 142a ( 142b). Looking closely at the joint between the fixed wear 142a and the variable wear 142b through the enlarged portion of FIG. 15, a pair is formed to be pin-coupled to the upper end of the front end of the fixed wear 142a and the upper end of the rear end of the variable wear 142b. A ring 142c is provided, and at the lower end of the rear end of the variable wear 142b, a leak prevention portion 142d extending in a fan shape is further provided on the side and bottom to prevent a gap from occurring with the fixed wear 142a during the tilting operation. provide

As described above, according to the configuration in which the variable wear 142b is tiltable, it is possible to adjust the overflow amount of sewage according to the tilting angle of the variable wear 142b. That is, when the variable weir 142b is tilted upward, the amount of overflow can be reduced without overflowing in the portion of the variable weir 142b located above the water surface. Otherwise, the variable weir 142b allows more overflow while allowing sewage to overflow at the same height as the overflow part 143 and the fixed weir 142a. As such, the overflow amount and discharge amount of sewage can be adjusted according to the tilting angle of the variable wear 142b. For example, as shown in FIG. 17, by lifting the front end of the variable weir 142b through which sewage flows in and placing it on the surface of the sewage water, the amount of sewage discharged through the overflow weir 140 becomes 70%. Here, if the variable weir 142b is further lifted, the amount of sewage discharged is further reduced. Conversely, as shown in FIG. 16, the variable weir 142b is lowered so that it is in a straight line with the fixed weir 142a, and the discharge of sewage becomes 100%. As such, since the discharge of sewage according to the tilting angle of the variable weir 142b varies according to the change in the water level of the sewage contained in the settling tank 100B, the tilting angle of the variable weir 142b may be adjusted in consideration of the water level. Here, the third actuator for the tilting operation of the variable wear 142b may be provided as a simple motor, hydraulic cylinder, pneumatic cylinder, etc., simply connected to the rotating shaft (hinge axis) of the variable wear 142b.

Furthermore, it is preferable that the variable wear 142b is configured to be manually tiltable separately from the third actuator. A lever or a winch may be installed for such manual manipulation, and when the winch is used, a wire is connected to the variable wear 142b.

In addition, with the wire and the winch, on the other hand, the upper ends of the overflow part 143 and the wear part 142 are formed in triangular waveforms so that the overflow of sewage starts in small amounts at multiple points at the beginning of the overflow, so that the sewage flows smoothly to induce

Furthermore, a plurality of wear parts 142 are installed so as to be individually operable on the left side and the right side. In this way, if a plurality of wear parts 142 are installed so as to be individually operable on the left side and the right side, it is possible to more freely control the discharge amount of sewage. In this way, three or more wear units 142 may be installed.

On the other hand, a first turbidity measuring sensor for measuring the turbidity of sewage flowing from the mixing tank 100A, a second turbidity measuring sensor installed on the top of the sedimentation tank 100B to measure the turbidity of sewage, and the precipitation tank ( Control of the flow of sewage by the flow equal distribution device 120 in consideration of the turbidity of sewage at each point measured by the third turbidity sensor measuring the turbidity of the sludge discharged from the bottom discharge groove 103b of 100B), The flow of sewage by adjusting the distribution amount of sewage for each inflow position by the variable rectification module 130 composed of the fixed rectifying wall 130A and the variable rectifying wall 130B and by controlling the amount of sewage discharged by the overflow wear 140 can be maintained smoothly and the purification efficiency for sewage can be maintained in the best condition.

As shown in FIG. 18, the washing water spraying device 160 is installed to spray washing water downward from the top of the rear wall and the left and right side walls of the settling tank 100B. The washing water spraying device 160 is horizontally installed with a tubular body at the top of each of the rear wall and the left and right side walls to receive the washing water, and the washing water spray nozzle to spray the washing water downward to the lower part of the tubular body. (161) is provided. In this way, when the elongated washing water spraying device 160 is installed on the left side wall, right side wall and rear wall of the settling tank 100B, the wall of the settling tank 100B is formed by the washing water sprayed three-dimensionally along the left side wall, right side wall and rear wall It is possible to effectively remove and discharge the sludge deposited from the bottom 103 to the bottom 103. At this time, the washing water sprayed from the washing water injection device 160 installed on the left and right side walls of the settling tank 100B flows along the left and right side walls and then along the bottom 103 of the settling tank 100B in a V-shape on the left and right sides. It gathers in the central part, which is the deepest part of the valley, and the washing water sprayed from the washing water spraying device 160 installed on the rear wall of the settling tank 100B flows along the rear wall and then descends to the bottom 103 that slopes downward toward the front of the settling tank 100B. It flows toward the outlet 104 for washing formed on the entire surface of the floor along the . In this way, the washing water sprayed from the washing water injection device 160 flows together with the sludge along the left side wall, right side wall and rear wall of the settling tank 100B, and then collects from the bottom to the center of the settling tank 100B. ) It is discharged and transported through the washing outlet 104 formed on the entire surface of the floor and the common pipe 105.

In order to increase the cleaning effect on the sludge deposited when the washing water spraying device 160 sprays, the bottom 103 of the settling tank 100B has a cross section with V-shaped valleys that deepen from both ends to the center. is formed In addition, according to this configuration, the washing water sprayed from the washing water injection device 160 flows together with the sludge along the left, right and rear walls of the settling tank 100B, and then collects from the bottom of the settling tank 100B to the center. Thereafter, the washing water and sludge are discharged and transported through the washing discharge port 104 formed on the front surface of the bottom of the settling tank 100B and the common pipe 105. Here, the bottom 103 of the immersion tank 100B not only has V-shaped valleys that deepen from both ends to the center, but also slopes downward toward the front, helping to discharge washing water and sludge.

Here, at the bottom of the settling tank 100B, as shown in FIG. 18, a guide groove 103a is further formed to guide the sludge flow by being connected to the sludge discharge groove 103b formed on the front side. In the drawing, the shape of the guide groove 103a is shown as a semicircular cross section, but a rectangular cross section is also possible. In addition, if only the flow of sludge can be made smoothly, it can be formed in various shapes.

The diffuser 150 is installed to generate aeration at the bottom of the settling tank 100B. As shown in FIG. 14, the diffuser 150 is formed of a body formed by connecting hollow tubes through which air is circulated in a mesh shape, and a plurality of air spray holes for spraying air upward in the mesh body. (151) is provided. Looking at the installation of the diffuser 150 placed on the bottom 103 of the settling tank 100B, as shown in FIG. In this state, the sludge is movable through the V-shaped valley of the bottom 103 of the settling tank 100B.

The diffuser 150 is provided in plurality to cover the bottom 103 of the settling tank 100B in the forward and backward directions and is continuously disposed in the forward and backward directions. And they are arranged in a state of being placed horizontally with a step difference with respect to each other. Accordingly, the diffuser 150 can also serve as a pedestal for stably supporting the filter medium cartridge 180M formed by loading a large amount of the filter medium 170 in the frame casing 180 from the lower side.

As such, the diffuser 150 generates aeration upward to separate the suspended particulate matter and the organic matter and nutrients contained therein from the filter medium 170 so that they are precipitated, and the washing water is sprayed. The device 160 strongly sprays washing water along the walls of the settling tank 100B to separate the sludge deposited on the walls and bottom 103 of the settling tank 100B, and the cleaning outlet 104 together with the materials separated from the filter media 170. ) through which it is induced to be discharged.

The filter medium 170 for water purification is a member that is charged in the sedimentation tank 100B of the water purification system and serves to precipitate particulate suspended matter contained in sewage and remove organic matter and nutrients contained in the suspended matter, as shown in FIG. It is made of any one of the illustrated bulge-type filter medium 170A and the hollow-type filter medium 170B, or includes both the bulge-type filter medium 170A and the hollow-type filter medium 170B.

The bulge-type filter media 170A is formed in a coil shape in which the body is rolled up, but is formed in a bulge shape having a bulge portion 171 that is more bulging than other parts, and is formed in a coil shape in which the body is rolled up, but is formed in a different part. It is laminated to correspond to the hollow-type filter medium 170B having a concave portion 172 that is recessed compared to the other. Here, the bulge-type filter medium 170A is not specifically shown in the drawing, but when the length is increased, the bulge 171 may be formed in a form in which the bulges 171 are spaced apart and repeatedly formed periodically.

On the other hand, the hollow-type filter medium 170B is formed in a coil shape in which the body is rolled, but is formed in a hollow shape having a concave portion 172 that is recessed compared to other parts. Such a hollow-type filter medium 170B is made to improve the stackability of the aforementioned bulge-type filter medium 170A, and is alternately stacked with the bulge-type filter medium 170A in a corresponding form. Here, the hollow-type filter medium 170B is not specifically shown in the drawing, but may be formed in a form in which concave portions 172 are spaced apart and repeatedly formed periodically when the length is increased.

When the bulge-type filter media 170A and the hollow-type filter media 170B are alternately stacked, as shown in FIGS. As the 172 are interlocked with each other, a stable laminated structure is formed in which the stacked state is not disturbed or collapsed. In this way, when the stacking stability between the filter media 170 is increased, the amount of stacking in the sedimentation tank 100B can be increased in the water purification system, and as shown in FIG. By configuring the filter medium cartridge 180M, it is very convenient to handle a large amount of filter medium 170 when periodically washing the settling tank 100B and carrying in and replacing the filter medium 170 with new ones. In addition, since the filter media 170 is stacked very regularly, regular gaps are formed in the piles of the filter media 170 stacked. Then, the aeration generated by the diffuser 150 uniformly penetrates through the gaps and actively contacts the surface of the body, so that the filter medium 170 is effectively cleaned by aeration.

As shown in FIGS. 21 and 22, the frame casing 180 constituting the filter media cartridge 180M together with the filter media 170 for water purification is capable of accommodating the filter media 170 by stacking them in a horizontal, longitudinal and It forms a skeleton structure made by connecting frames in the horizontal and vertical directions, and has an open top and side surface. In addition, the bottom of the frame casing 180 is open to allow sewage to flow, but is provided with a net to stably support the loaded filter media 170 . In this way, if the frame casing 180 for loading the filter media 170 is provided, the filter media 170 is stacked on the frame casing 180 from the time of manufacture in the factory instead of inserting and stacking the filter media 170 one by one in the settling tank 100B. By providing the filter medium cartridge 180M in the form of a cartridge 180M, a large amount of filter medium 170 can be simply carried into the settling tank 100B in the form of a cartridge 180M. Thereafter, when washing the settling tank 100B and the filter medium 170 or replacing the filter medium 170, a large amount of filter medium 170 is stacked on the frame casing 180 instead of taking out the filter medium 170 from the settling tank 100B one by one. It can be taken out and processed at once in units of the filter medium cartridge (180M).

In this way, when the filter medium cartridge 180M is configured in a form in which a large amount of filter media 170 is stacked by the frame casing 180, it is convenient to manage the large amount of filter media 170 in units of cartridges 180M. Here, the frame casing 180 is preferably made of a rectangular parallelepiped because it is suitable for the filter media cartridges 180M to be closely accommodated in a connected form facing each other in the settling tank 100B as shown in FIG. 22 . According to the drawing, the filter medium cartridge 180M accommodated in the settling tank 100B is shown in a form placed on the diffuser 150, and the filter medium cartridge 180M accommodated in the settling tank 100B is the size of the diffuser 150 placed below. And the shape, the size of the inner space allowed in the settling tank 100B, the flow of sewage, etc. can be comprehensively considered, and efficiency can be improved by changing the size and arrangement interval rather than being provided with the same size.

The body of the water purification filter medium 170 is made of a porous material having a porosity of 50 to 90% to adsorb organic matter and nutrients of particulate suspended matter contained in the sewage, as well as to provide a microbial growth environment, It may be made of any one of plastic material, alumina sulfate, iron salt, lime, and polymer coagulant. As such, the present applicant has developed the function, material, and material of the filter medium 170 for depositing and removing particulate suspended matter and nutrients from sewage flowing into the settling tank 100B through biological and physical/chemical reactions. Korean Patent Registration No. 10-0441755 (July 15, 2004) disclosed by the above can be referred to.
