Description

Water and sewage water purification system using cylindrical storage tank {WATER PURIFICATION SYSTEM USING CYLINDER TYPE STORAGE TANKS}

The present invention relates to a water and sewage water treatment system using a cylindrical storage tank, and to a water and sewage water treatment system using a cylindrical storage tank for treating water resources such as a water source, a dam, a valley water, and a river as drinking water.

In general, drinking water means drinking water that has been treated to be suitable for the normal use of natural water and natural water, as defined in the Ministry of Environment's Drinking Water Management Act amended on August 28, 1997.

In other words, drinking water is a spring water, such as natural water (groundwater in a rock aquifer, spring water, etc.) that is not harmful even if it is ingested for a lifetime for various harmful substances, and a drinking water prepared by applying physical / chemical treatment to be suitable for eating such spring water. And water resources (water sources, dams, valleys, rivers, etc.) can be classified as tap water purified for drinking water.

In particular, tap water has been thoroughly managed for the health of the public because most of the people drink it economically for a lifetime.

Water and sewage treatment system according to the prior art, as shown in Figure 1, mostly using the floating method, the raw water in the state before the water treatment in the dam or the source (1) to secure water resources such as rainwater, river water, valley water, etc. Get supplied.

In addition, the conventional water treatment system has a watering well (2) for equally adjusting and distributing the flow rate of the raw water supplied, PAC (polyaluminum chloride) automatically according to the amount of raw water and the water quality in order to easily remove various turbidity in the raw water, Chemical input facility (3) for injecting chemicals such as aluminum sulfate, slaked lime and activated carbon into mixed paper, mixed paper (4) which is a facility for adding purified water to raw water and mixing it with a stirrer, and the mixed matter uniformly in mixed paper A flocculation paper (5) for condensation into large chunks that are easy to sink, a flocculant (6) for soaking and clearing condensed flocs (floc) from the flocculation paper, and fine suspended solids not removed from the flocculation paper. Filter water (7) filtered by A / C (Anthracite) and advanced water treatment to remove harmful substances in the water not removed from the filter paper by passing through ozone contact and bioactive carbon filter paper. Facilities (8), water purification facilities (9) for temporarily storing water after chlorine disinfection and fluorine injection into purified water through advanced water treatment facilities, and water supply pump facilities (10) for supplying tap water from the water purification facilities to households (11) )

As mentioned above, since the conventional water treatment system is based on the flotation method, corresponding treatment facilities, that is, a chemical input facility (3), mixed paper (4), flocculation paper (5), sedimentation basin (6), As a result of the need for facilities such as filter paper 7, there is a disadvantage in that water can be purified into edible water only through a large site and complicated procedures.

In addition, in view of the fact that the water of the water source 1 used as raw water is contaminated with various industrial contaminants and loses its function as a water resource, the MACF (Micro Air Coagulate Flotation) method, the lower layer laminar flow method using a biofilm, and reverse contact Oxidation paper method, natural vegetation method using aquatic plants and aquatic plants, high speed agglomeration sedimentation method, Hollow Fiber Micro Filter or Membrane method, membrane separation activated sludge method (MBR: Membrane BioReactor) have been developed. It is applied to the processing.

In particular, the hollow fiber precision filtration membrane method can be found in the 2001 Korean Patent Registration No. 311618, 'Water treatment equipment using inclined sedimentation battery and hollow fiber precision filtration membrane'. It consists of a flow control tank, aeration tank with a fine screen, a fixed-phase contact media unit for microbial treatment of raw water, a treatment tank, a sludge storage tank, etc., so that the sewage and organic wastewater purification process is easily and simply made in a short time.

In the patented technology, the conventional membrane separation water treatment system effectively utilizes manufacturing and installation space and simultaneously removes organic matter, SS (suspended solids), nitrogen, and phosphorus in sewage and wastewater. It is well known that the quality of treated water can be guaranteed. Here, the membrane separation method is a technology that can replace the flocculation, sedimentation, sand filtration with a single membrane separation process using a bio-reactor, a pump and a membrane filter of the membrane separation activated sludge method.

Nevertheless, the technology is fully applied to water and sewage water treatment systems, so that the production of drinking water is not only necessary, but also requires a large amount of existing sedimentation basins and water purification facilities. Disinfectants (chlorine, fluorine, etc.) in the sterilization method is still commercially used.

Therefore, the water we drink currently remains unprotected against the problem of residual chlorine concentrations that can cause cancer and various diseases, and in practice, sedimentation basin or purified water which requires a larger area is used and manufactured. And the efficiency of the installation space is very far away.

On the other hand, there is a membrane separation activated sludge method that theoretically does not require chlorine, for example, in a membrane type activated sludge method which claims that no sedimentation basin is necessary, but even if the water can be purified aseptically, Problems in which bacteria and organics are regenerated according to the environment when storing water or transporting water after treatment are found. As a result, it is still inevitable to disinfect water with a disinfectant.

On the other hand, the residual chlorine concentration of water stored in the storage tank is maintained in the water quality of less than 1.0mg / l to 1.5mg / l per liter when treated by the conventional flotation method in Korea.

According to Article 2 (3) of the Regulation on Cleaning and Sanitation Management of Water Facilities, the residual chlorine of tap water is maintained at 0.2 mg / l or more, or 0.4 mg / l or more in case of contamination or contamination of hospital microorganisms. However, since the upper limit of residual chlorine is not legalized, the disinfectant is overdosed, and there is a concern that tap water with a relatively high residual chlorine concentration may be supplied to each household. If drinking water with high residual chlorine concentration is used as it is, it causes problems such as aesthetic discomfort and the production of disinfectant by-products. In other words, if tap water with excessive residual chlorine concentration is supplied to the home, it may not be suitable for drinking water because of the smell of water in the water, and may increase the possibility of generating carcinogenic trihalomethane (THM), whereas chlorine When the water is disinfected at low concentrations, accidents may occur that provide the user with water containing various invisible bacteria and the like.

Therefore, the WHO set the maximum limit of residual chlorine concentrations such as 5mg / l, US 4mg / l, Japan 1mg / l, Australia 5mg / l, etc. By doing so, we are doing our best to believe and drink in each family.

In addition, the storage tank or water storage facilities of the conventional water treatment and sewage treatment system are mostly concrete type storage tanks installed in the basement, and it is difficult to maintain and repair such as immediate response due to leakage and inflow of sewage. Mold may occur on the inner wall of the storage tank, and as the product life of the storage tank approaches, it serves as a major culprit of water pollution and at the same time, does not provide the consumer with reliability for clean water.

In addition, the conventional water and sewage water treatment system takes a lot of land, as well as requires a long production time compared to the manufacturing cost has an uneconomical disadvantage.

In addition, since the storage tanks used in the conventional water and sewage treatment system are mostly formed in a rectangular shape and water is generated at the corners, even if the purified water is contaminated, the water may be contaminated. There is a disadvantage that is not easy

In addition, in the conventional water and sewage treatment system, since water does not flow smoothly in the water stagnation site, there is a disadvantage in that dilution performance of liquid and solid chlorine, ozone, fungicide, disinfectant, and the like is inferior.

Accordingly, in the water and sewage water treatment system, it is difficult to eradicate bacteria, and excessive disinfectant is inevitably introduced, and an excessive concentration of disinfectant can be combined with organic substances to generate carcinogens.

Accordingly, an object of the present invention is to solve the conventional problems described above, by arranging multiple partition cylindrical storage tanks serving as a sedimentation basin and an impingement treatment tank of a membrane separation natural filtration method in a compact system installation area, It is to provide a water and sewage water treatment system using a cylindrical storage tank that can maximize performance.

In addition, another object of the present invention is to manufacture and install the system equipment in a short time by the laminated manufacturing method of the cylindrical unit can be used semi-permanently due to the stainless material is economical, easy to maintain and repair because it is installed on the ground The present invention provides a water and sewage water treatment system using a cylindrical storage tank.

As shown in FIG. 2 and FIG. 3, the present invention is a facility for treating water resources such as water or rivers secured in a dam, a dam, and valley water to treat drinking water.

The impingement treatment tank 100 and the storage tanks 200, 400, 500, and 700 provided in the present invention are manufactured by a manufacturing method of laminating and welding cylindrical units made of a flange shape by bending the upper end and the lower end. Such a process includes, for example, 2001 No. 237585, 2001 No. 246330, 2002 No. It is easily found in No. 271280.

The present invention, which further develops such a storage tank manufacturing method, has a concrete base portion 102, 202, 302, 402, 502, 602, 702 compactly arranged in a relatively small site area, and an upper surface of the central base portion 102. Installed in the impingement treatment tank 100 using a membrane separation natural filtration method of the stainless material, the cylindrical first storage tank 200 having a multi-partition so as to serve as a settlement, and activated carbon filtration to filter harmful substances in the water It is responsible for the facility 300, the second and third storage tanks (400, 500) to extend the settling distance, the chemical injection facility (600) to inject disinfectants such as chlorine, fluorine, water purification It consists of a fourth storage tank (700). Here, the stainless material used in the present invention is 'STS444', 'DUPLEX2205, 2206', etc., which are strong in corrosion resistance, durability, and impact resistance for structural materials, and 'KS D 3595' and 'KS D 3576' for pipe members. Etc. can be used.

The bases 102, 202, 302, 402, 502, 602, 702 are concrete blocks erected at a height of 30 cm to 6 m from the ground for the natural flow through the drop, and 1 m for the same height for the transfer pump. It is responsible for supporting the facilities and storage tanks to be described in detail. In the present invention, since the base portions 102, 202, 302, 402, 502, 602, and 702 can be formed by using a natural flow type and a transfer pump type, the height of the base portion is not limited.

As shown in the drawing, the bases 102, 202, 302, 402, 502, 602, and 702 for the natural flow of water flow may include the first storage tank 200 and activated carbon at the installation position of the impingement tank 100. It is disposed in the coil direction (counterclockwise in the drawing) to the installation position of the filtration facility 300, the second and third storage tanks (400, 500), the chemical injection facility (600), the fourth storage tank (700), Each step is lowered stepwise to have a predetermined height difference, that is, a height difference within 1m to 3m (H1> H2> H3> H4), so that water flows down naturally.

In addition, although not shown in the drawings, the base for the transfer pumped water flow maintains a horizontal plane and simply supports each component equipment and tank at a height of 1 m from the ground, and the water flowing in the equipment and tank is Pressurized by a transfer pump (not shown) coupled to the connecting tube.

In the following, the transport path of the foreign matter (including sludge) indicated by the dashed arrow, and the water transport path indicated by the solid arrow, but the water and sewage water treatment system of the present invention disposed on the natural flow type in accordance with the order of the transport path I will explain in detail.

The impingement treatment tank 100 pipes the water inlet pipe 800 which has a timing valve (not shown) in the upper part. The raw water of the water resource to be purified through this is obtained from the upper portion of the impingement treatment tank 100 (W / I: Water In), and purified by membrane separation natural filtration method to be described below. The impingement treatment tank 100 is placed on the top surface of the base portion 102 at a higher position than other components so that water can flow to each storage tank or facility 200 to 700 located at a lower position. It is designed.

The inside of this base part 102 is provided with the installation hole which has a cone-shaped lower narrow inclined surface. Correspondingly, the impingement treatment tank 100 forms a lower structure corresponding to the installation hole, so that the sludge collected in the lower structure flows into the sludge treatment facility 101 through the first connection pipe 810. do. At this time, the inflow means of the sludge uses a pump or a natural flow method. In addition, although not shown, the first connection pipe 810 includes a timing valve, and is configured to open and close the pipe at a time interval corresponding to an operation process of the water treatment system.

In addition, the second to seventh connection pipes 820 to 870 to be described below are inclined corresponding to the inclination gradient of the base, respectively.

The sludge treatment facility 101 uses a drying heat source like a rotary kiln, and slowly rotates the powder in a cylindrical combustion furnace to dry the sludge by rotating the sludge by rotation and stirring, and then cools and recycles the building material. It is a conventional equipment for manufacturing such a detailed description thereof will be omitted in the present invention. In addition, the impingement treatment tank 100 is piped to supply water to the first storage tank 200 through the inclined second connecting pipe 820.

The first storage tank 200 has a cylindrical body manufactured by the manufacturing method to be described in detail below, there is almost no shooter by flowing the water to be stored therein in a circular direction, and because there are multiple partitions therein It is characterized by the fact that the width and length of the circular flow path can be extended as appropriate for the water treatment system.

For example, the main body of the first storage tank 200 has a multi-barrier structure, has a height of about 4 m, a diameter of 18 m to 20 m, and an internal volume of 1000 m 3 to 1600 m 3, but actual water storage capacity is 900 to 1100 tons. In the case of manufacturing using the applicant's cylindrical unit manufacturing apparatus (2001 Korean Patent Application No. 17648 in 2001) that can manufacture the cylindrical unit vertically, it can be produced more than that.

Since the first storage tank 200 having such multiple bulkheads and a method of manufacturing the same are disclosed in detail in the above-mentioned utility model registrations and 2002 Korean Patent Application No. 4085 filed by the present applicant, the description thereof Omitted from the invention.

Since the first storage tank 200 having such a multi-partition structure has walls formed of a ring shape, a spiral shape, and the like, it provides an annular to spiral chamber which is divided by the walls. The chamber is a circular flow path through which water flows, and may be defined by its width and length. That is, when the first storage tank 200 has a diameter of 18 m and three walls are mounted in the tank at 2.5 m intervals, the width of the circular flow path is 2.5 m and the circumferential length of the flow path is centered in the outer first chamber. To 4th chamber of 56.5m, 40.8m, and 25.1m respectively. When summed up, the first storage tank 200 has a flow length of water of more than 120 m. In addition, even if the first storage tank 200 has a main body of the same diameter (18m) to increase the number of multiple bulkheads to five and accordingly to reduce the distance between the walls to 1.5m, that is, even if having the same installation area water flow The length can be designed to extend from the 120m to almost 200m. Then, the first storage tank 200 is piped to supply water to the activated carbon filtration facility 300 through the third connecting pipe (830).

Activated carbon filtration facility 300 is a micropore of 5A ~ 150A using activated carbon having a strong adsorption capacity of 1000㎡ / 1g ~ 1600㎡ / 1g, taste, smell, color, residual chlorine, neutral detergent (ABS), It is a filtering device that adsorbs and removes radioactive materials, and is a common filtering facility using 8 mesh to 30 mesh activated carbon. This activated carbon filtration facility 300 has excellent performance in removing the smell of the water, color, and is piped to supply water to the second storage tank 400 through the fourth connecting pipe (840).

The second storage tank 400 is in charge of the same or similar shape and function as the first storage tank 200 mentioned above, and stores the water filtered by activated carbon, and the fifth connection pipe 850 in the drawing. It is piped to supply water to the third storage tank (500) through.

In the present invention, by providing the pipe connection member 851 in the fifth connection pipe 850, the advanced water treatment facility 450 for passing ozone contact and bioactive carbon filter paper is the second storage tank 400 and the third storage tank. Can be interposed between 500.

The third storage tank 500 plays a role of extending the flow path of the second storage tank 400, thereby extending the settling distance. The third storage tank 500 is manufactured in the same and similar shape as the first and second storage tanks 200 and 400, and serves to store while flowing more water. The third storage tank 500 is piped to supply water to the chemical injection facility 600 through the sixth connection pipe 860.

The chemical injection facility 600 includes a device for adding a disinfectant such as chlorine and fluorine, and an input amount control means. The chemical injection device 600 is a conventional facility capable of adding chemicals at predetermined intervals or flow rates using an electronic flow meter and a timer. to be. Disinfectants are expensive in liquid form and are therefore dissolved in water after being introduced into the solid form. In this case, the disinfectant needs to be uniformly dissolved in water, and in order to optimize the residual combustion concentration, it is necessary to purify the water to have a long mixing time of the disinfectant.

The role of the purified water in the present invention is the fourth storage tank 700 that is supplied with water is piped to the chemical injection facility 600 to the seventh connection pipe 840.

As described above, the fourth storage tank 700 also has a length of 120 m to 200 m in which the water flows in the interior, and the water flows linearly and flows through the partition walls in turn, thereby increasing the contact time between the water and the disinfectant. Therefore, it is manufactured to control the residual combustion concentration by controlling the above-mentioned disinfection ability (CT).

For example, the first to fourth storage tanks 200, 400, 500, and 700 each have a linear flow for 2 to 8 hours, rather than a few minutes, until they are obtained according to the design of the internal multi-partition walls. There are features that can be delivered.

Whether or not the fourth storage tank 700 of the present invention is really suitable as a purified water, will be described through the disinfection ability (CT) of Equation 1 below.

CT = residual disinfectant concentration (mg / L) x disinfectant contact time (min)

Here, the residual disinfectant concentration takes the minimum value of the daily measured residual disinfectant concentration value. The disinfectant contact time, which is the time when water and disinfectant contact each other, should be measured from the initial disinfectant injection point to the purified water discharge point, or the point where the value of inactivation ratio is recognized at the maximum daily flow rate.

In practice, when measuring the contact time of disinfectant, the contact time is the time until 10% of the tracers put into the initial disinfectant injection point to the water discharge point or the point where the value of the inactivation ratio is recognized. do.

In case of using theoretical contact time, however, the hydraulic retention time according to the water purification structure (reserved water usage capacity divided by the maximum flow rate per hour) multiplied by the distillation wall conversion factor of [Table 1] below, the actual contact time of the disinfectant. To calculate.

In the above table, the long width ratio is the ratio of the water flow length and the water flow width in the purified water, and it is difficult to determine the conversion coefficient according to the long width ratio. The conversion factor for pipeline flow is assumed to be 1.0.

Therefore, in the case of the fourth storage tank 700, the width is 2.5m when the water flow length is 120m, and the width is 1.5m when 200m, so the long width ratio is converted into 48 and 133, respectively. The coefficient is from 0.7 to 0.9. In particular, the other storage tanks (200, 400, 500), including the fourth storage tank 700 also has a conversion factor because the water has a linear flow to the inside of the storage tank (almost no water production) and overflows The conversion factor is close to 1.0.

In conclusion, since the fourth storage tank 700 has a high conversion factor value, the contact time of the actual disinfectant may be long, and thus, the fourth storage tank 700 may have a very excellent disinfection ability.

This fourth storage tank 700 is connected to the eighth connection pipe 880 and the water pump facility (not shown) for supplying the stored drinking tap water to each household, so that each household can receive reliable drinking water. It can be provided.

In the following, the structure and membrane separation natural filtration method of the impingement treatment tank 100 as described above will be described in detail.

4 and 5, the membrane separation natural filtration method of the impingement treatment tank 100 may be a micro membrane filter which is a membrane separation natural filtration filter while a foreign substance having a relatively large specific gravity in the influent sinks to the lower state. In this case, the sludge treatment facility is collected through the first connection pipe 810, and the remaining water is filtered and discharged.

To this end, the impingement treatment tank 100 is manufactured by the lamination method of the above-mentioned cylindrical unit 110, that is, the cylindrical unit 110 of the stainless steel material formed by bending the upper and lower flanges (111, 112) Each of them is welded after being stacked in four stages, and the upper plate 40 having the manhole 41 and the plurality of reinforcement plates 42 is covered and welded thereon.

At this time, the water inlet pipe 800 is welded to the center of the upper plate (40). Each cylindrical unit 110 is wound by the insulating material 113 and is insulated, and finished with a thin sheet of exterior material 114 covering the insulating material 113. The exterior member 114 is fixed to each of the flanges 111 and 112 by the fixing clip 115 and the fixing pin. The lower end of the impingement treatment tank 100 is coupled to the cylindrical filter unit 120 to form a space in which the micro membrane filters can be built in a sunflower shape. The filter unit 120 is made of cylindrical units 119 and 129 having the same shape or relatively large diameter of the cylindrical unit 110 described above, but the upper portion of the glass window 122 and the hinged open / close covers 121. And the bottom thereof is sealed with the bottom plate 118. Here, the glass window 122 is mounted for the purpose of internal observation, the hinged cover 121 is for the maintenance of the micro membrane filter mounted therein.

In addition, the outer wall of the filter unit 120 has a second connection pipe 820 penetrating the inside, so that the water filtered through the micro membrane filters is discharged to the first storage tank (W / O: Water Out) To be. In addition, the lower portion of the filter unit 120 is coupled to the cone-shaped collection unit 130 having a lower side slope, after the sinking foreign matters through the first connection pipe 810 (Sludge Out) To the sludge treatment plant.

Referring to the detailed coupling relationship through Figure 5, the filter unit 120 is the outer cylindrical unit (119), the outer cylindrical unit (119) wound around the inner member (119) and the outer member (114 ') having a similar shape as mentioned above ( 129) forms a wall. Here, the inner diameter of the ring-shaped bottom plate 118 having a predetermined width is welded to the edge portion of the collecting portion 130, and the outer diameter of the bottom plate 118 is welded to the edge portion of the outer cylindrical unit 129, The lower part of the filter unit 120 is sealed.

Although the impingement treatment tank 100 is not shown for cleaning and maintenance, the ladder is mounted inside and outside thereof, and is installed on the lower side slope 103 of the cone shape of the concrete base 102 described above, and the impingement treatment. The filter unit 120 of the bath 100 is supported on the top surface of the base 102.

On the other hand, the raw water (a, b) introduced into the inner space 108 of the impingement treatment tank 100, the timing valve of the first connecting pipe 810 is closed and the raw water by the action of the timing valve of the water inlet pipe 800 During the impingement process (a, b) is no longer introduced into the impingement treatment tank 100, due to the operation of the micro-membrane filter 140 to be described in detail below, it is divided into foreign matter (b) and water (a) do. However, the coagulant injector 900 is indicated at the inlet portion of the water inlet pipe 800 coupled to the upper plate 40 of the impingement treatment tank 100 so as to accelerate the initiation process more efficiently. May be combined separately. The coagulant injector 900 injects the coagulant (c) into raw water including water (a) indicated by a solid arrow and foreign matter (b) indicated by a dotted arrow, thereby causing the foreign matter (b) to become entangled with each other, thereby providing more efficient water. It is separated from, and settles down.

That is, the sunken foreign matter (b) exits through the cone-shaped collection unit 130 and the first connecting pipe 810, the water (a) is a micro membrane filter ( As it passes through the 140, it flows from the inner space 108 to the unit space 128.

As shown in FIG. 6, the micromembrane filters 140 are components for normal water treatment disposed in the unit space 128 at regular intervals in a sunflower shape.

Referring to the configuration of the micro membrane filter 140 schematically, a timing valve for opening and closing the first discharge pipe 144 piped through the inner cylinder unit 119 to open and close in accordance with the operation process of the water treatment system ( 141, the hollow fiber membrane 142, the built-in pump 145, the 'b' shaped release tube 143, and includes a control unit 148 connected by wires to control the pump and the valve.

Referring to Figure 7, the hollow fiber membrane 142 is placed so that water flows in the vertical direction.

Due to the operation of the built-in pump and the timing valve in the process of ①, when the inside of the micropores (0.1 μm to 0.4 μm) of the hollow fiber 142 'indicated by the cross section is depressurized, the external water passes through the inside and the organic matter Foreign matter such as SS, nitrogen, phosphorus 149 is filtered by the fiber of the hollow fiber.

Due to the operation stop of the built-in pump and the timing valve in the process of ②, if the decompression state is canceled, the foreign matter 149 flows together with the external water.

Through the repetition of the above process, as shown in FIG. 6, water is introduced into the unit space 128, and foreign substances remain in the inner space 108 of the impingement treatment tank 100 and settle in the collecting unit 130. In the opening operation of the timing valve of the first connecting pipe 810, the sludge treatment equipment connected to the first connecting pipe 810 is introduced.

On the other hand, the water introduced into the unit space 128 is rotated in the clockwise direction by the action of the 'b' shaped release tube 143, it is introduced into the storage tank to be described later through the second connecting pipe (820).

As shown in FIG. 8, the first storage tank 200 used in the present invention has a top plate 210 composed of a handrail 211, a manhole 212, a ventilation port 213, and a radial shape at the bottom of the top plate. The cross-type reinforcing rods 220 are arranged to have an internal ladder 230 and an external ladder (not shown) for the access of the manager for maintenance and cleaning. In addition, the first storage tank 200 partitions each ring-shaped chamber by multiple partition walls 245 formed inside the outer wall body 240. In particular, the multi-partition walls 245 and the outer wall 240 are manufactured by seamlessly stacking cylindrical units of stainless material as mentioned above, and then welding all of the contact portions. These multiple partition walls 245 have a plurality of through-holes or inclined flow guide pipes 241, 242, 243 formed in the uppermost cylindrical unit so that the water can flow over and flow. In addition, a second connection pipe 820 is piped through the outer wall body 240 so that water flows in.

The first storage tank 200 of the present invention has a bottom plate 250 of the 'V' shape fixed to the multiple partitions 245 and the outer wall 240. The bottom plate 250 forms a cleaning hole piped with the cleaning pipe, respectively, and can stabilize the initial flow of water by the 'V' groove shape, because the sediment in the water is collected in the center of the groove, It is easy to collect.

These bottom plates 250 are each welded to seal the bottom of the ring-shaped chamber.

In addition, the concrete base portion 202 on which the first storage tank 200 is installed is formed with a plurality of 'V' grooves corresponding to the shape of the bottom plate 250, and the cleaning pipes 831 and the discharge pipe The third connector 830 is installed to play a role.

As shown in FIG. 9, when the water flows into the outer first chamber through the second connecting pipe 820, the first storage tank 200 is formed by the relative height difference or the pressure of the transfer pump. The linear flow is repeated in the second chamber, the third chamber, and the fourth chamber in the center, which pass through the plurality of inclined flow guide tubes 241, 242, and 243, and the linear flow (indicated by the arrow) is repeated. After that, it is discharged to the third connecting pipe (830).

In addition, in the description of the present invention, since the second, third and fourth storage tanks are similar to and identical to the structure of the first storage tank 200 described above, detailed descriptions of the respective coupling method and operation method will be omitted herein. .

As shown in FIG. 10, the storage tanks provided in the present invention include four inlet valves (vi-1 to vi-4) piped to a connection pipe through which water is supplied (W / I), and water is discharged (W). 4 outlet valves (vo-1 to vo-4) piped to the / O) connection pipe and 4 cleaning valves (vc-1) piped to the connection pipe where the wastewater generated when fresh water is drained (WW / O) Vc-4). Each of these valves has a drain hole.

Thus, the storage tanks can withdraw water in a given chamber or store and flow water in the remaining chambers by selective opening and closing of these valves, thereby making it possible to clean the chamber without watering, You can control the distance.

For example, when the storage tank is in normal use, four cleaning valves (vc-1 to vc-4), three inlet valves (vi-1, vi-2, vi-3) and three outlet valves ( Since vo-2, vo-3, and vo-4) are sealed, the water to be obtained is introduced into the outer first chamber through the open inlet valve vi-4, and then the second chamber and the third After filling the chamber, the fourth chamber in the center, the water is discharged through the open water outlet valve vo-1.

However, when the cleaning worker wants to clean only the fourth chamber in the center without the water, the water is closed by opening the 'vo-2' in the closed water outlet valve vo-1 while closing the water outlet valve vo-1. Make sure that the fourth chamber is not filled (ie, water is drawn into the first chamber and immediately exited through the second and third chambers and vo-2). In addition, by opening the 'vc-1' of the cleaning valve was closed, it is possible to drain the sewage.

In this state, the cleaning worker wears clean work clothes, enters the third chamber through the manhole, closes the outlet hole of the fourth chamber with the prepared stopper, and cleans the inner surface of the fourth chamber. Afterwards, the sewage generated during cleaning is discharged through 'vc-1', and comes out after finishing cleaning work (unplugging and disinfecting).

Then, the cleaning worker seals the cleaning valve 'vc-1', seals the 'water discharge valve' vo-2 ', and opens the' vo-1 'to return the storage tank to the normal state.

In this way, the other chambers are also selectively opened and closed as necessary to the inlet valve, the cleaning valve and the outlet valve, respectively, so that only the desired chamber can be cleaned, and the description of each case is omitted here.

In addition, in controlling the flow distance of the water, the operator can adjust the valves so that the water can be discharged directly through the water outlet pipe of the specific chamber while the water is not sequentially filled from the central fourth chamber to the outer first chamber. You can do that.

In this case, the operator can have the storage tank have a relatively short flow distance compared to the flow distance through which the water flows when all are filled with water.

And, since the valve operation method is similar to the method of filling or emptying the chamber for the cleaning, its detailed operation method will be omitted.

Hereinafter, the water purification method of the water and sewage water treatment system using the cylindrical storage tank of the present invention will be described.

As shown in Fig. 11, in the water purification method of the present invention, raw water to be purified is obtained from the upper portion and stored in the inner space of the impingement treatment tank (S10). The stored raw water is separated from the water and foreign matter in a natural filtration method by the operation of the timing valve of the micromembrane filter and the built-in pump while the raw water is kept in the impingement tank. That is, foreign matters of raw water such as organic matter, SS, nitrogen, and phosphorus precipitate in the inner space of the impingement treatment tank, while water separated from the raw water is introduced into the unit space of the impingement treatment tank through the micro membrane filter. Then, the precipitated foreign matter sinks to the bottom and is collected to the sludge treatment facility through the collecting unit and the first connection pipe (S20).

On the other hand, the water introduced into the unit space separated through the micro membrane filter as described above flows through the second inclined pipe is stored in the first storage tank. Water in the first storage tank flows along the 'V' groove on the bottom of the multiple bulkheads and fills the internal space of the chamber. The water flows through the inclined flow guide tube formed in the upper portion, and in turn, the center of the outer first chamber Up to the fourth chamber of (S30). The filled water flows out through the third connecting pipe piped to the bottom of the fourth chamber, and then flows along the inclined third connecting pipe and enters the activated carbon filtration facility. In activated carbon filtration equipment, a filtering process in which the taste, smell, color, residual chlorine, neutral detergent (ABS), and radioactive substances contained in water are adsorbed and removed is performed (S40).

Thereafter, the water discharged from the activated carbon filtration equipment is introduced into the second storage tank through the fourth connecting pipe (S50). In particular, all the storage tank in the present invention is to be stored so that the water flows continuously, and has a feature that there is almost no pool of water according to the shape of the cylinder. In addition, the water of the second storage tank flows more clearly and cleanly according to the effect of extending the settling distance in the fifth connector and the third storage tank. In addition, when the advanced water treatment facility is provided in the fifth connection pipe, a step of passing the ozone contact and the bioactive carbon filter paper may be performed (S60).

This continuously flowing water is introduced into the chemical injection facility through the sixth connection pipe, and then subjected to disinfection treatment according to chlorine disinfection and fluorine injection (S70).

After the sterilized water flows into the fourth storage tank through the seventh connection pipe, the concentration of residual chlorine is controlled while flowing and overflowing the chambers in which the contact time between the water and the disinfectant is extended (S80).

Then, the purified water through the eighth connection pipe is provided to each household as reliable drinking water by the water pump facility.
