Description

ONE CHAMBER TYPE WATER TANK HAVING WATER PURIFICATION FUNCTION}

The present invention relates to a single water tank-type water tank having a water treatment function and a water treatment method thereof, and more particularly, to purified water for human consumption of raw water such as groundwater, valley water, dam storage water, water source, and river water. The present invention relates to a single tank type water tank having a water treatment function capable of carrying out mass treatment and storage in one place with one drinking water.

In general, the water storage tank is a basic storage means for storing water divided into shapes, such as rectangular, cylindrical, wave type, multi-bulk type, etc., and the panel assembly type, masonry type, unit stack type, and materials used according to the construction method thereof. Depending on the concrete, resin, stainless steel can be divided.

Such a water storage tank is usually used for water supply, and serves to clean and safely store purified water through water and sewage treatment facilities and water treatment plants in advance.

Here, the general water and sewage treatment facility means a filtration plant, which is a water well, a chemical injection facility, a mixed pond, a flocculation pond, a sedimentation basin, a filter paper, an advanced water treatment facility, a clear wall, a water pump, It consists of a drainage basin and supplies a large amount of purified water to where it is needed.

However, water for drinking as living water is not enough to be supplied to people with fully equipped cities, but also to people such as villages, mountains, wallpaper, islands, and flooded areas.

In other words, in mountainous, remote areas, wallpaper, islands, and flood areas, water and sewage treatment facilities are not well equipped or existing facilities are destroyed, which is very inconvenient to use drinking water. Although water is collected and recycled, drinking water by itself can be life threatening due to health and hygiene problems.

In addition, even when using spring water, well water, etc. due to the purification of the ground, there is a possibility that water may be contaminated after a drought or disaster, and the amount of use is limited, so inconveniences in areas where water is scarce cannot be expressed in words. It is true.

The safe supply of drinking water is very important in the mountains, remote areas, small towns, villages, villages and islands where water supply is difficult.

There are still many areas where water produced by poor systems is stored in inappropriate reservoirs and used as a constant.

Therefore, there is a need for a new material tank that can drastically improve problems such as FRP tanks, concrete reservoirs, and SMC water tanks, which are used as existing reservoirs, and the development of functional water tanks with water production capacity as well as reservoirs is important. Have

In particular, 'Stainless 444' and 'Duplex' materials are not only excellent in terms of cleanliness and hygiene, but also have a semi-permanent lifespan, and are excellent materials that can solve corrosion by chlorine as a disinfectant. Using such materials, a functional water tank with a water purification function is urgently needed for a large-capacity water tank with an economical structure and a low water capacity with excellent sterilization and disinfection effect.

In view of this, the present applicant has applied for a 'functional water tank having a water supply water treatment system' of Patent Application No. 10-2003-88710, and a 'pure water treatment system for water tank' of Patent Application No. 10-2003-88714. It has been filed.

In particular, the functional water tank of '710 is a functional water tank having a water purification water treatment system having at least one outer wall and an inner wall wrapped with a heat insulator and a finish, as disclosed in the claims, wherein the outer wall and A main body in which the inner wall is arranged like a multi-barrier structure and partitioned inside into a raw water treatment chamber and a water treatment chamber; An upper cover coupled to an upper portion of the main body; A bottom plate coupled to the lower portion of the main body; A plurality of partition walls fixed upwardly from the bottom plate and fixed between an inner wall body and an outer wall body of either the raw water treatment chamber or the water treatment chamber; It includes a machine room formed to have a predetermined space inside the main body by the partition wall and the inner wall body.

That is, the summary of the patent application is briefly summarized, that is, a plurality of chambers consisting of a raw water treatment chamber and a purified water treatment chamber, for example, providing a tank structure in which two tanks are arranged in a ring shape, A machine room is provided inside the two tanks, and the water treatment system is provided inside the machine room.

However, since the disclosure disclosed in the patent application consists of two tanks in terms of construction economy, it is a fact that they are relatively expensive tank equipment in terms of construction economy.

That is, the conventional '710 functional water tank has a disadvantage in that a stainless material equivalent to one of a large capacity water tank is required as opposed to using a raw water treatment chamber as a means for admixing a flocculant to raw water before filtration and sterilization.

In particular, due to the raw water treatment chamber, the conventional functional water tank may have a relatively high maintenance cost, which does not meet the needs of consumers who require a low-cost functional water tank.

In order to solve the above-mentioned problems, the present invention is a single tank tank structure in which the machine room is located inside the chamber, and the line mixer and the buffer tank provided in the machine room produce a clean water for drinking. Its purpose is to provide a single tank type water tank with water treatment function that is very convenient for system installation, operation and maintenance management, fully automatic operation of the device, and excellent construction economic efficiency.

In addition, another object of the present invention is to provide a combined structure of the upper cover and the machine room partition reinforcement structure to realize a single tank tank structure, it is possible to increase the durability of the tank structure, while reducing the construction period compared to the installation area It is to provide a single tank type water tank having a relatively low water capacity treatment function.

Here, the hydraulic distributor 241 is a conventional device for controlling the input and output direction of the hydraulic pressure.

The hydraulic strut shaft 231 expands and contracts when supplying and recovering hydraulic pressure, and the rack gear interlocking with the operation shaft rotates the pinion gear, so that the upper media rack connected to the pinion gear is connected to the lower media rack fixed to the bottom. At the same time as the reference is rotated, a pore control operation such as twisting (counterclockwise), unwinding (clockwise), or the like, of a fiber bundle such as the media hanging on the upper media holder is performed. This air gap control operation is performed to the signal for backwashing is input to the filtering device 230, at this time, aeration air is supplied from the following air supply device 260, to collect foreign matter, sludge, etc. gathered in the fiber bundle It will be washed.

Hereinafter, the coupling relationship and operation relationship of a single tap water treatment system 400 having a pressurized flow function, a coagulation function, a filtration function, a disinfectant chemical input function, and a backwashing function of the basic water of the present invention will be described.

Referring to FIG. 4B, the raw water inlet pipe 150 is piped to receive raw water in the buffer tank 290. The raw water inlet pipe 150 is coupled to the first electronic valve 271 so that the raw water can be supplied to the buffer tank 290 from an external source.

At this time, the reprocessing inlet pipe 158 is connected to the raw water inlet pipe 150 through the three-way connection pipe, and the coagulant inlet pipe 156 extending from the electron pump 211 of the coagulant injector 210 is reprocessed. It is connected to the inlet pipe 158.

Thereafter, the buffer tank 290, the pressure pump 220, the line mixer 295 is piped in a line by a predetermined connection pipe.

That is, the outlet pipe of the buffer tank 290 is piped to the inlet port of the pressure pump 220, the outlet pipe of the pressure pump 220 is piped to the inlet port of the line mixer 295.

The outlet pipe of the line mixer 295 is branched into a first branch pipe 221, a second branch pipe 222, and a third branch pipe 223.

The first branch pipe 221 is connected to the reprocessing inlet pipe 158.

The second branch pipe 222 is connected to the inlet port 237 of the filtration device 230.

The third branch pipe 223 is connected to the drain pipe 153.

The first drain connection pipe 233 is penetrated to the third branch pipe 223. That is, the first drain connecting pipe 233 is for discharging lower sludge, dirt, sewage, etc. generated during filtration or back washing, and the first drain port 239a and the third portion of the lower part of the filtration device 230. It is piped between the branch pipes 223.

The second drain connector 236 is for discharging upper sludge, dirt, sewage, etc. generated during backwashing. One end of the second drain connector 236 is connected to the upper second drain port 239b of the filtering device 230, and the other end of the second drain connector 236 is connected to the drain tube 153. It is.

The reprocessing inlet pipe 158 is branched from the second drain port 239b or the second drain connector 236 at the upper side of the filtration device 230 so that the coagulant inlet pipe 156 and the raw water inlet pipe 150 Meet.

Through this, as necessary, the buffer tank 290 is purely obtained from the outside, and the sludge, dirt, and filthy water of the filtration device 230 obtained through the reprocessing inlet pipe 158 are combined.

Sludge, dirt, sewage, and flocculant of the filtration device 230 are contained, but a part of the raw water that needs to be reprocessed plays a role as a coagulation aid in the buffer tank 290 and the line mixer 295.

Originally, flocculating aids are acids, alkalis, activated silica, 'polyelectrolytes', clays (eg 'bentonite'), and the like, which are additive materials for increasing the flocculating efficiency of the flocculant, but in the present invention, no flocculating aids are used.

In addition, in order to supply external air necessary for back washing to the inside of the filtering device 230, an air injection pipe 155 extending from the air supply device 260 is connected to the air injection port of the filtering device 230. .

The purified water inlet pipe 159 is connected to the water outlet port 238 of the filtration device 230 to supply the filtered water to the purified water treatment chamber 102.

At this time, the purified water inlet pipe 159 is connected to the chemical input pipe 160 extending from the disinfecting chemical input device 250.

Hereinafter, using the water tank body 100 of the present invention, '1. Integer process 'and' 2. Coagulation aiding process 'and' 3. I'll explain the backwashing process.

1. Water purification process.

The manager closes the first open / close valve 280 and the second open / close valve 281 in advance.

The manager turns on the power to the controller 200.

The controller 200 opens the first electron side 271 and closes the ninth electron side 279.

Accordingly, the water (raw water) existing in the surface water source, the valley water source, or the underground water source is obtained only through the raw water inlet pipe 150 to the buffer tank 290.

The controller 200 transmits a coagulant input signal to the coagulant input device 210.

The coagulant injector 210 injects a predetermined amount of coagulant into the buffer tank 290 according to the coagulant input signal. At this time, the addition of the flocculant is in compliance with the predetermined time control control, and may vary depending on the actual system variable value, so specific and detailed details thereof are omitted in the present invention.

Until the first water level sensor 119 detects full water, the water is filled in the buffer tank 290 in a simply turbid state with the flocculant.

The controller 200 maintains the first electronic valve 271 in an open state, except when the first water level sensor 119 detects full water, malfunctions, or a system stop.

When the first water level sensor 119 detects full water, or when a predetermined time (a predetermined time at the time of designing the flow control control by calculating the flow rate in advance) elapses immediately after the opening time of the first electronic valve 271, the control unit 200 Drives the pressure pump 220.

At this time, the controller 200 closes the fourth electron valve 274 to prevent water from flowing into the third branch pipe 223 connected to the drain pipe 153.

On the other hand, the control unit 200 opens the second electronic valve 272 to allow water to flow into the second branch pipe 222 connected to the inlet port 237 of the filtering device 230, and at the same time, the purified water inlet pipe 159. The third electron side 273 on) is opened.

As a result, the water in the buffer tank 290 is completely mixed with the coagulant while passing through the line mixer 295 by the pressure pump 220, the water mixed with the coagulant is the second branch pipe 222 and the second electron valve ( Through the inlet port 237 and 272 into the filtration unit 230.

The control unit 200 operates the hydraulic supply device 240 in advance to generate a hydraulic pressure of a predetermined pressure, and controls the hydraulic distributor 241 together with the operating shaft of the hydraulic strut shaft 231 as described above. Allow it to stretch. In this case, the bundle of fibers (media) between the upper medial ledge and the lower media ledge is twisted and at the same time the voids are narrow enough to perform filtration sufficiently.

The control unit 200 closes the fifth electron valve 275 and the eighth electron valve 278 in a general water purification process, so that sludge, sewage, and the like, which may occur during filtration, may be reprocessed inlet pipe 158 or second drain connection. It does not flow into the pipe 236 and the drain pipe 153.

In addition, the control unit 200 closes the sixth control valve 276 to prevent the air generated by the air supply device 260 from being introduced into the filtration device 230, and together with the seventh electronic valve 277. ) To prevent the backflow phenomenon of the drain pipe 153 in advance.

In this state, the water under pressure according to the operation of the pressure pump 220 continues to pass through the fiber bundle within the filtering device 230 to become filtered water.

The filtered water flows toward the purified water treatment chamber 102 through the discharge port 238, the third electron valve 273, and the purified water inlet pipe 159.

At this time, the disinfectant chemical input device 250 is put into the filtered water as follows.

Here, the principle of disinfecting chemical input uses the level of water level detected by the second water level sensor 129 and the index data value recorded in the memory of the controller 200 by the experiment.

The data value of the index means a quantitative value determined by a pre-validated test result (drug input amount by flow rate, drug input amount by time interval, drug input amount by water level (water volume), etc.).

For example, the controller 200 compares and checks the water level level detected by the second water level sensor 129 at any one of the index data values at predetermined time intervals, and then corresponds to the coincidence value when the water level is matched. The chemical input signal corresponding to the chemical input amount is transmitted to the disinfecting chemical input device 250.

As a result, the disinfecting chemical input device 250 receiving the chemical input signal is input to the purified water treatment chamber 102 by the amount of the disinfecting chemical corresponding to the chemical input signal.

The water in the state containing the disinfecting chemicals is obtained into the water treatment chamber 102 and then remains in the water treatment chamber 102 for a predetermined time period during which the disinfecting chemicals can be diluted.

The controller 200 opens or closes the ninth electronic valve 279 by any one of a time control, a flow rate control, and a water level control control program stored in the memory, thereby preserving water through the purified water discharge pipe 152. It is to be supplied to a water pump or a predetermined drainage station.

2. Coagulation secondary process.

The manager who determines that the coagulation assistance process is necessary opens the first opening / closing valve 280.

The manager presses a control button of the coagulation assistance process of the controller 200.

The control unit 200 opens and closes the eighth control valve 278 according to the aggregation assistance process algorithm recorded in the memory.

The flocculation assisted process algorithm uses a predetermined data sheet (index) with results obtained in advance of the test on how much of the wastewater should be returned (re-introduced) to the buffer tank 290.

Of course, the coagulation assistance process algorithm can also be programmed to open and close the eighth control valve 278 repeatedly for a predetermined time that is simply primitive. The predetermined time at this time is determined through numerous tests, and is not specific as it depends on various environmental values.

On the other hand, while the eighth control valve 278 is open, the filthy water having a considerable size of particles discharged from the filtration device 230 and flocculated by flocculating agent (agglomeration of flocs) in advance is used. After mixing with the newly introduced sewage in 290, and completely mixed in the line mixer 295, the size of the floc becomes larger and thicker and more dense at the same time.

The control unit 200 immediately closes the eighth electronic valve 278 again immediately after receiving an overload pressure signal generated as a preset pressure abnormality is detected from an internal pressure sensor installed inside the filtration device 230, and at the same time, Perform a backwash process such as

3. Backwash process.

The controller 200 automatically closes the first, second, and third control valves 271, 272, and 273 (every time an overload pressure signal is input), so that raw water flows into the filtering device 230, or filtered water The water purification is prevented from flowing back into the filtration device 230, and the eighth electromagnetic valve 278 is closed to prevent the sewage or the like from flowing back into the buffer tank 290.

Although not shown in the drawing, the backwash water supply pipe extends from an external washing water supply device (not shown) operating according to the backwash water supply signal of the control unit 200, such that the air injection pipe 155 at the bottom of the filtration device 230 is provided. Piping around.

The control unit 200 controls the hydraulic distributor 241 to direct the supply and collection directions of the hydraulic pressure generated in the hydraulic supply device 240 in the opposite direction, so that the operating shaft of the hydraulic strut shaft 231 is reduced. In this case, the fiber bundle (media) between the upper medial girder and the lower medial girdle is released and at the same time the voids are fully open and are in very good condition to backwash.

The controller 200 closes the seventh electron side 277 and opens the fifth electron side 275 and the sixth electron side 276, respectively. In this state, the control unit 200 enters the air having the predetermined pressure of the air supply unit 260 (pressure enough to aeration the sewage in the filtration unit) to the inside of the filtering unit 230, the air supply unit ( 260 to supply power.

In addition, the control unit 200 operates the external washing water supply device so that the backwash water flows into the filtration device 230 through the backwash water supply pipe.

The backwash water and air aeration the inside of filtration device 230. In the fiber bundle shaking in the aeration state, tangled sludge, foreign matters, etc. are shaken off, and upward flow is generated.

Since the fifth electronic valve 275 is open and the eighth electron valve 278 is closed, the backwash water and the air supplied for a predetermined time are in the second drain port 239b and the second drain connector 236. And discharged to the outside through the drain pipe 153.

On the other hand, after the backwashing for a predetermined time, the control unit 200 stops the operation of the external washing water supply device and at the same time closes the sixth electronic valve 276.

In addition, the control unit 200 stops the air supply device 260 by shutting off the power applied to the air supply device 260 with the operation of the external washing water supply device stopped.

The control unit 200 opens the seventh electron valve 277 to discharge the backwash water remaining in the filtration device 230 through the first drain connection pipe 233 and the drain pipe 153 in a natural drainage manner. .

The control unit 200 again controls the hydraulic distributor 241 to extend the operating shaft of the hydraulic strut shaft 231.

In this case, the fiber bundle (media) between the upper medial girder and the lower medial girdle is twisted and at the same time has a very good gap for filtration.

The control unit 200 closes the fifth electron valve 275 and the seventh electron valve 277 and simultaneously opens the first, second, and third electron valves 271, 272, and 273, thereby performing the normal water purification process described above. Will run again.
