As shown, the continuous flow, sequential washing type composite water treatment apparatus according to the present embodiment includes a cylindrical treatment tank 12 for processing the raw water introduced through the inlet pipe (10).

The lower end 14 of the treatment tank has a funnel shape, and a discharge pipe 16 for discharging the concentrated water concentrated with contaminants is connected to the bottom. The discharge pipe 16 is configured to be opened and closed by the discharge valve (M2).

The treatment tank 12 is formed in a multiple partition wall structure to have a plurality of chambers. Specifically, the overflow chamber So formed by the first cylindrical partition 18 located at the center and the overflow chamber So Balancing tank (Sv) formed by the second cylindrical partition wall 20 which is located outside to surround the filtration chamber (S _f ) is formed between the balancing tank (Sv) and the inner surface of the treatment tank (12) And a precipitation concentration chamber Sc.

The overflow chamber So and the balancing tank Sv are configured to be separated independently from the filtration chamber S _f and the precipitation concentration chamber Sc of the treatment tank 12.

According to the present invention, the overflow chamber (So) and the balancing tank (Sv) is communicated with the outside through the vent 22, while the filtration chamber (S _f ) and the precipitation concentration chamber (Sc) is sealed to block the outside This is to filter the raw water by pressure by the driving force of the filtration pump (P1).

Further, in the present invention, the overflow chamber So and the balancing tank Sv are sequentially formed in the center of the treatment tank 12, and the filtration chamber S _f and the precipitation concentration chamber Sc are provided on the outside of the plurality of filtrations. This is to compact the device structure while securing sufficient space for installing the module.

According to the present invention, the raw water to be treated is supplied by the pressing force of the filtration pump P1, and the raw water is filtered according to the pressurized pressure method. In order to filter the raw water, a plurality of unit filtration modules are installed in the space between the balancing tank Sv and the inner surface of the treatment tank 12. Here, the unit filtration module constitutes a basic unit in which filtration or washing is performed independently. The unit filtration module is composed of at least one filtration member 24. Each unit filtration module is separated independently from other unit filtration modules.

In this embodiment, as can be seen in Figures 2 to 4, one filtration member 24 is installed with the support bracket 26 closed to constitute one unit filtration module, the unit filtration module is a total You can see that eight are installed.

However, it is to be understood that the number and size of the filtration member 24 and the unit filtration module are not particularly limited by the present invention and may be appropriately set according to the size and treatment capacity of the water treatment apparatus.

The filtration member 24 may include a filtration membrane for passing water and filtering contaminant particles and a frame for supporting the filtration membrane. The filtration membrane may be configured by combining a plurality of meshes having fine holes formed in multiple layers. Typically, the filtration membrane may be made of stainless steel or synthetic resin or fiber, but is not limited thereto, and a filtration membrane of various materials capable of filtering water may be employed.

The filtering member 24 may be configured in a cylindrical shape, but is not limited thereto, and it should be understood that filtering members having various shapes and shapes may be employed.

According to the present invention, the raw water induction pipe 28 is installed to surround the outer surface of the filtration member 24. At this time, the gap between the raw water induction pipe 28 and the filtration member 24 is not limited in size, and may be appropriately set according to the raw water treatment capacity and the size of the apparatus.

The raw water induction pipe 28 extends to the upper part with the lower end of the filtration member 24 closed, and the upper end is open. Therefore, the filtration chamber (S _f ) is formed in the space between the raw water induction pipe 28 and the filtration member 24, the remaining space becomes a precipitation concentration chamber (Sc).

The inlet pipe 10 is connected to the filtration chamber (S _f ) and the raw water is introduced. Preferably, for example, a distribution pipe 30 extending in a circular shape is installed to communicate with the filtration chamber S _f in the plurality of unit filtration modules, and the inlet pipe 10 is provided with the distribution pipe 30. Connected. Therefore, the raw water introduced into the treatment tank 12 through the inlet pipe 10 may be evenly supplied to the filtration chamber S _f in the plurality of unit filtration modules through the distribution pipe 30.

Preferably, the distribution pipe 30 is installed in the lower space of the filtering member 24, but is not limited thereto, as shown in detail in Figures 4 and 5, the distribution pipe 30 a plurality of The water inlet 32 is formed so that the raw water is injected into the upward direction from the water inlet 32 toward the filtration member 24.

On the other hand, the raw water induction pipe 28 is connected to the bottom of the raw water induction pipe 28, the lower end thereof is connected to the adjacent raw water induction pipe 28 through the filter chamber shared pipe 34, which will be described later It is to collect sediment weight solids or contaminants and discharge them to the outside.

To this end, the lower end of the raw water induction pipe 28 preferably has a funnel shape, and the filter chamber sharing pipe 34 interconnecting the ends of the raw water induction pipe 28 is discharge pipe through the solid discharge pipe 36 again. Connected with (16). In FIG. 1, reference numerals M1 and M3 denote valves for opening and closing the inlet pipe 10 and the solid discharge pipe 36, respectively.

As described above, an end of the filtration member 24 is coupled to the support bracket 26 in an airtight manner to form a drainage end D, which is a closed area, and at one end of the filtered water supply pipe 38 at the drainage end D. This is connected to supply the filtered water from the unit filtration module to the overflow chamber (So).

That is, the filtered water supply pipe 38 is connected to the drain stage D of the unit filtration module so as to independently supply the filtered water from the filtration member 24 in each unit filtration module to the overflow chamber (So).

In addition, the other ends of the plurality of filtered water supply pipes 38 are collected and coupled to the lower end of the overflow chamber So.

As shown in FIG. 3, the first cylindrical partition 18 constituting the overflow chamber So extends to an appropriate height, and an upper end thereof is open so that the water flowing into the overflow chamber So is first. It overflows from the upper end of the cylindrical partition 18 is introduced into the balancing tank (Sv).

According to this embodiment, the overflow pipe 60 is provided to discharge the light pollutants having a relatively low specific gravity. The overflow pipe 60 is installed such that its inlet is adjacent to the ceiling inside the precipitation concentration chamber Sc. The overflow pipe 60 is connected to the discharge pipe 16 is configured to discharge the pollutants with a small specific gravity to the outside. Reference numeral M4 not described in FIG. 1 denotes a discharge valve for opening and closing the overflow pipe 60.

According to the present embodiment, the overflow chamber So is configured to perform an AOP process for treating sterilization, purification, and deodorization of the filtered water by simultaneous action of ultraviolet rays and ozone (O ₃ ).

Specifically, a plurality of ultraviolet lamp units 40 are installed in the vertical direction in the overflow chamber So. The ultraviolet lamp unit 40 includes a transparent tube made of a quartz tube having excellent transmittance and the like, and an ultraviolet lamp mounted in the transparent tube. The transparent tube serves to protect the UV lamp by blocking it from water.

The ultraviolet lamp unit 40 is supported by being placed on the lower bracket (42 in FIG. 3) located at the bottom, the upper end of which is suspended on the cover bracket 44 covering the upper part of the overflow chamber So and the balancing tank Sv. Supported. Preferably, the ultraviolet lamp unit 40 is configured to detachably detach each unit, and more preferably may be configured to detach the entire ultraviolet lamp unit together with the cover bracket 44.

In addition, the continuous flow, sequential washing type composite water treatment apparatus according to the present embodiment may further include an ozone supply means for supplying ozone to the overflow chamber (So).

The ozone supply means includes an ozone generator 46 for generating and supplying ozone, an ozone supply pipe 48 for supplying ozone generated by the ozone generator 46, and ozone supplied through the ozone supply pipe 48. At the end of the branch pipe 50 for mixing with the filtered water and transported to the overflow chamber (So), and the ozone injection pipe 52 connected to the lower portion of the overflow chamber (So) to inject the ozone into the water in the form of fine bubbles. An ozone diffuser 54 is installed.

The branch pipe 50 is branched from each of the filtered water supply pipes 38, and is connected to communicate with each other through the branch sharing pipe (56). That is, since the branch sharing pipe 56 is connected to all the branch pipes 50, the filtered water flowing through each branch pipe 50 is eventually collected through the branch sharing pipe 56.

As described above, the reason for employing the branch sharing tube 56 connecting the respective branch pipes 50 in the present invention is that any one of the specific branch pipes 50 performing the cleaning process, as described later, performs the filtration process. This is because filtrate water having a relatively high pressure flows compared to the branch pipes 50. Due to this pressure difference, a back pressure is transferred through the branch sharing pipe 56, thereby blocking the one-way check valves 58 placed on the path of the remaining branch pipes 50. According to this operation, the filtered water flowing to the remaining branch pipes 50 is blocked, and the high pressure filtered water flowing to any one of the specific branch pipes 50 flows to the ozone injection pipe 52 without pressure loss. do.

Furthermore, the branch sharing pipe 56 may be configured as a single ozone injection pipe 52 from the overflow chamber So, and the ozone supply pipe 48 may be connected to the ozone injection pipe 52. Therefore, when the filtered water flows inside the injector placed on the path of the ozone injection pipe 52, ozone is introduced from the ozone supply pipe 48 by the venturi effect according to the pressure difference generated at this time, and the introduced ozone is Mixed with the filtered water is injected into the overflow chamber (So) through the ozone diffuser 54 as shown in FIG. Here, FIG. 6 is a view showing the overflow room So in a state in which the ultraviolet lamp unit 40 is removed for convenience of description.

The ozone diffuser 54 is installed at the end of the ozone injection pipe 52 connected to the bottom of the overflow chamber So. Preferably, the ozone diffuser 54 is a synthetic resin foam for spraying finely ozone. It may be configured in the form of (Form) or in the form of a mechanical nozzle, membrane, and the like.

Meanwhile, the purified water sterilized in the overflow chamber So flows over the upper end of the first cylindrical partition 18 and flows into the balancing tank Sv. The balancing tank (Sv) is a function of balancing the amount of water and the amount of water to be received as a temporary storage space before the final water treated in the continuous flow, sequential washing type composite water treatment apparatus according to the present invention is discharged Do it.

A water outlet is formed at the bottom of the balancing tank Sv, and a discharge pipe 62 is connected thereto. The treated purified water may be discharged in a natural flow manner through the discharge pipe 62 or may be discharged by pressure pumping by installing a circulation pump P2 in the discharge pipe 62.

According to the present invention, the filtration member 24 may be sequentially washed while the water treatment apparatus filters the raw water. Specifically, the filtration member 24 may be repeatedly washed by the unit filtration module.

To this end, cleaning pumps P3 are provided on the paths of the plurality of filtered water supply pipes 38, respectively, to provide a driving force for backwashing the filtration member 24 by sucking a part of the filtered water from the inside of the overflow chamber So. According to a feature of the present invention, each of the filtered water supply pipe 38 is provided with a cleaning pump (P3) independently, in this case it is possible to ensure a stable and reliable operation. In addition, the cleaning pump (P3) is enough to employ a small pump having a relatively small size and capacity because it only needs to exhibit a function capable of backflowing the filtered water through a single filtered water supply pipe (38). This feature is one factor that can reduce power consumption while reducing the size and weight of the composite water treatment apparatus according to the present invention.

1-2. Device behavior

Then, the preferred operation of the continuous flow, sequential washing type composite water treatment apparatus according to the present invention having the configuration as described above will be described. The complex water treatment apparatus according to the present embodiment performs a continuous flow, sequential washing type advanced treatment in which sediment concentration, fine filtration, and advanced oxidation mechanisms are mixed with raw water.

Sediment Concentration and Filtration Process

When the filtration pump P1 is driven in the state in which the electric valve M1 shown in FIG. 1 is opened, for example, raw water from the closed pond is in the unit filtration module in the treatment tank 12 along the inlet pipe 10. It flows into each filtration chamber S _f . At this time, the discharge valve M2, the valve M3 and the discharge valve M4 is in a closed state.

As described above, the flocculant may be selectively added automatically in the process of introducing the raw water to further promote the flocculation precipitation reaction.

The raw water flowing into the inlet pipe 10 is evenly distributed along the distribution pipe 30 provided in a circular shape on the lower filter chamber (S _f) is introduced into the filter chamber (S _f) from the retrieving hole 32.

At this time, since the water inlet 32 is formed upward toward the filtration member 24, raw water is obtained from the bottom toward the filtration member 24.

In this process, heavy solids or relatively large contaminants contained in the raw water settle and accumulate on the bottom of the raw water induction pipe 28 and inside the filtration chamber sharing pipe 34, and light contaminants having a relatively low specific gravity are described above. It flows upward along the space between the filtration member 24 and the raw water induction pipe 28 and is integrated in the uppermost layer of the precipitation concentration chamber Sc in the treatment tank 12.

At the same time, the raw water in the filtration chamber (S _f ) is filtered while passing through the filtration membrane of the filtration member 24 in the process of flowing along the space between the filtration member 24 and the raw water induction pipe 28. In the present embodiment, the filtration of the raw water is performed by the pressure method by the driving force of the filtration pump (P1). Therefore, the operating pressure required for filtration can be appropriately set by adjusting the pressing force of the filtration pump P1 according to the amount of filtered water, the characteristics of the raw water and the filtration membrane, and the like. In addition, because of the forced pressurization method, it is possible to employ a microporous filtration membrane, which enables ultra-precision filtration.

Contaminants filtered by the filtration member 24 as described above is attached to the outer surface of the filtration membrane, water is introduced into the filtration member 24 through the filtration membrane.

AOP process

The filtered water filtered by the filtration member 24 is introduced into the overflow chamber (So) along the filtered water supply pipe 38 connected to the drainage end (D) of the unit filtration module. Specifically, since the filtrate supply pipes 38 are independently connected to a plurality of unit filtration modules (eight in this embodiment), the filtered water will be supplied through the filtrate supply pipes 38 corresponding to the number of unit filtration modules. .

The filtered water introduced through the bottom of the overflow chamber (So) is irradiated with ultraviolet rays by the ultraviolet lamp unit 40 installed therein while flowing upward, and at the same time exposed to ozone which is finely diffused through the ozone diffuser 54. While being sterilized and purified.

In more detail, a portion of the filtered water flowing into the bottom of the overflow chamber So through each filtered water supply pipe 38 is started through the start of the corresponding cleaning pump P3 which provides a driving force for cleaning any specific unit filtration module. High pressure filtered water flowing through the filtered water supply pipe 38 and flowing into a specific branch pipe 50 connected with a pipe path in this process is passed through the branch sharing pipe 56 on the path of the ozone injection pipe 52. Ozone is introduced from the ozone supply pipe 48 due to the Venturi effect caused by the pressure difference while flowing inside the injector. As a result, the introduced ozone is mixed with the filtered water and injected into the overflow chamber So through the ozone diffuser 54 installed at the end of the ozone injection pipe 52.

As is known, ozone oxidizes organic and inorganic substances contained in untreated water, and oxidizes E. coli, bacteria, viruses, hepatitis and cooling disease bacteria (Legionella). In addition, ozone inhibits the formation of THM, a carcinogenic substance through oxidation, and removes cyanide, detergent, phenol, manganese and magnesium.

In addition, bacteria, bacteria, viruses, microorganisms, and the like present in raw water are destroyed by an ultraviolet ray having a wavelength of about 253.7 nm emitted from the ultraviolet lamp (UV).

At the same time, OH-radicals are generated during the decomposition process in which ozone contained in dissolved ozone water is reduced to oxygen by ultraviolet rays, thereby further increasing sterilization power. OH-radicals are known to have a higher potential difference than ozone and to react evenly with almost all organic materials at a very high speed. Most organic compounds that react with OH radicals are oxidatively decomposed to water and carbon dioxide. In this way, OH-radicals effectively kill SARS, bird flu, viruses, Mycobacterium tuberculosis, O-157, Salmonella, Listeria, and other infectious flu viruses and bacteria.

The purified water treated after performing the AOP process as described above overflows the top of the first cylindrical bulkhead 18 and flows into the balancing tank Sv, and is then discharged to the bottom of the balancing tank Sv. Follow 62) to proceed to the subsequent process.

Preferably, the discharge pipe 62 may be connected to, for example, an activated carbon adsorption treatment apparatus, and the treated water may be re-supplied to a pond or the like and used as heavy water or tap water.

In this case, the circulation pump P2 may be selectively operated as needed. The circulation pump P2 has a water level within the balancing tank Sv that satisfies the planned operating range, that is, between the high water level HWL and the low water level LWL. Under these conditions, it is controlled variably and balances treated water outflow with system inflow.

Cleaning process

According to the present invention, while filtering the water as described above, the plurality of filtration members 24 may be sequentially cleaned for each filtration module.

In detail, while the raw water is filtered, the cleaning pump P3 provided in the specific unit filtration module requiring cleaning is operated. Then, a part of the filtrate inside the overflow chamber (So) flows back through the corresponding filtrate supply pipe 38 in accordance with the operation of the cleaning pump (P3) through the drain stage (D) of the unit filtration module filtration member 24 Flows into the interior.

At this time, the high-pressure filtered water also flows to the branch pipe 50 connected to the corresponding filtered water supply pipe 38, and the filtered water passing through the corresponding one-way check valve 58 reaches the branch sharing pipe 56, where the filtration process Since the filtered water flowing into the remaining branch pipes 50 performing the cleaning process is relatively lower than the pressure in the branch pipe 50 connected to the corresponding filtered water supply pipe 38 flowing back to perform the cleaning process, the branch sharing pipe 56 is used. It flows backward along and blocks the one-way check valves 58 placed on the paths of the remaining branch pipes 50 at the same time. Thus, the filtered water passing through the filtration member 24 of the unit filtration module to perform the filtration process flows into the overflow chamber (So) along the filtration water supply pipe 38 and the unit filtration module performing the cleaning process is pressure loss in the corresponding pipe. Without high pressure filtered water is supplied to the ozone injection pipe 52 through the branch sharing pipe 56, the injection of ozone can continue without interruption.

As described above, the filtered water flowing back into the filtration member 24 drops out contaminants adsorbed on the outer surface of the filtration membrane while flowing from the inside of the filtration membrane to the outside.

The contaminants thus removed are discharged out of the raw water induction pipe 28 by the mixed water of the incoming raw water and the backwash water. That is, the raw water received through the inlet pipe 10 into the filtration chamber S _f and the backwash water spouted from the inner surface of the filtration member 24 by flowing the filtrate water supply pipe 38 back to the filtration chamber S _f) some errors W flow into each other in the (S _f) to flow into the other filter chamber (S _f) adjoining on a shared W that is in communication with the lower error pipe 34 while the remaining portion has the filter chamber (S _f As it exits into the space between the filtration member 24 and the raw water induction pipe 28 of the c), it flows together with the contaminants concentrated in the upper part and is discharged to the top of the raw water induction pipe 28.

According to the invention, the filter chamber (S _f) the original error more than in the state that is defined by the feeding conduit (28) (S _f) in the contaminants periodically, one feeding conduit (28, by a subsequent washing step was inside ), The concentration of the filtration chamber (S _f ) does not increase over time, thereby allowing continuous and effective filtration.

Contaminants discharged to the top of the raw water induction pipe 28 as set forth above is settled downward and are accumulated at the bottom of the precipitation concentration chamber Sc. In the present invention, the filtration chamber (S _f ) and the precipitation concentration chamber (Sc) is separated by the raw water induction pipe 28 and the raw water is supplied only to the filtration chamber (S _f ) through the inlet pipe 10, sediment concentration The contaminants can be stably concentrated at the bottom of the precipitation concentration chamber (Sc) without being floated or refluxed again.

According to the present invention, the filtration process is continued in the remaining (7 in this embodiment) unit filtration modules while one unit filtration module is cleaned. In addition, after cleaning is performed for one unit filtration module for a predetermined time, the cleaning is sequentially performed while the cleaning pump P3 of another adjacent unit filtration module is operated.

In addition, in order to clean the filtration member 24, the pressing force of the filtered water flowed back by the cleaning pump P3 should be greater than the pressing force applied to each filtration member 24 by the filtration pump P1. For example, when one washing pump P3 operates at a pressure corresponding to twice the pressing force applied to each filtration member 24, all the water filtered by the other two filtration modules is used for washing. The filtered water from the remaining five unit filtration modules is discharged normally.

Light pollutant removal process with low concentration and discharge of concentrated water

When contaminants are concentrated in the precipitation concentration chamber Sc during the raw water treatment as described above, the discharge valve M2 is opened and the contaminants are discharged.

Such pollutant discharge may be performed manually, but, for example, may be configured to be automatically performed every predetermined time.

According to the present invention, the contaminants deposited in the treatment tank 12 may be maintained without stopping the operation of the water treatment device or blocking the continuous flow of raw water. That is, when the discharge valve (M2) is opened when the discharge of contaminants is required, the contaminants that have settled on the bottom of the precipitation concentration chamber (Sc) are discharged to the outside through the discharge pipe (16) together with the water.

In the present invention, the sedimentation concentration chamber (Sc) is separated from the filtration chamber (S _f ) and is not affected by the inflow of raw water, thereby enabling the high density concentration of the pollutants, so that the pollutants can be sufficiently discharged to the outside with only a small amount of water consumption. have. The contaminants discharged in this way can be subsequently treated using a dehydration tank or the like.

Such concentrated water discharge may be made in real time, wherein the instantaneous instantaneous concentrated water discharge is preferably equal to or less than the amount of raw water inflow flowing into the treatment tank 12 through the inlet pipe 10, and thus raw water inflow during drainage. The cleaning process can be carried out continuously while maintaining the yield.

Subsequently, if it is determined that the precipitated concentrated contaminants have been discharged to some extent, or after a predetermined time has elapsed, the discharge valve M2 is automatically closed and the normal water treatment process is continued again.

In addition, in the present invention, since the solid weight is precipitated in the bottom of the raw water induction pipe 28 constituting the filtration chamber (S _f ) and the filtration chamber shared pipe 34 connected thereto, the solid discharge pipe (36) manually or automatically if necessary. By opening the valve (M3) posted on the path of) to discharge the heavy solids with water to the discharge pipe (16).

Furthermore, in the continuous flow, sequential washing type composite water treatment apparatus according to the present embodiment, a light conduit may be manually or automatically carried out if necessary, even when light pollutants having a relatively low specific gravity accumulated in the uppermost layer of the precipitation concentration chamber Sc as the operation time elapses. The discharge valve M4 placed on the path of 60 is opened to be discharged together with the water. That is, the light pollutants having a relatively low specific gravity tend to accumulate on the top layer without being settled to the bottom of the precipitation concentration chamber Sc, but there is a problem that the discharge is difficult unless all the water in the treatment tank 12 is discharged. However, according to the present invention, such a light pollutant having a small specific gravity can be discharged relatively easily through the overflow pipe 60 during operation.

Specifically, in the case of removing light contaminants having a small specific gravity accumulated in the upper layer of the precipitation concentration chamber Sc, the discharge valve M4 placed on the path of the overflow pipe 60 during operation is manually or automatically. Therefore, the light pollutants having a small specific gravity together with the water are effectively discharged along the overflow pipe 60.

It is sent to So.

Subsequently, the filtered water introduced into the overflow chamber So is sterilized and purified through the ultraviolet lamp unit 40 and then overflows from the upper end of the first cylindrical partition 18 to be introduced into the balancing tank Sv. Thereafter, the water is discharged to the outside of the treatment tank 12 through the discharge pipe 62 connected to the bottom of the balancing tank Sv.

According to the present invention, a three-way valve 70 is installed at a branch point of the branch pipe 50. The three-way valve 70 selectively selects a path between the filtrate supply pipe 38 and the branch pipe 50. Open and close by That is, the three-way valve 70 is closed instead of opening the path of the filtered water supply pipe 38 from the filtration member 24 toward the overflow chamber (So), the path to the branch pipe 50 is closed, or the filtered water supply pipe Instead of closing the path of 38, the path to the branch pipe 50 is opened.

On the other hand, the branch pipe 50 is connected to communicate with the adjacent branch pipes 50 through the branch sharing pipe 56.

5-2. Device behavior

Next, a preferred operation of the continuous flow, sequentially rinsing combined water treatment device according to the present embodiment will be described. Similarly to the apparatus shown in FIG. 1, the complex water treatment apparatus according to the present embodiment performs a continuous flow and sequential washing type advanced treatment in which sediment concentration, fine filtration, and advanced oxidation mechanisms on the raw water are combined.

Sediment Concentration and Filtration Process

First, when the filtration pump P1 is driven while the electric valve M1 is opened, raw water flows into the filtration chamber S _f of each of the unit filtration modules inside the treatment tank 12 along the inlet pipe 10. do. At this time, the discharge valve M2, the valve M3 and the discharge valve M4 is in a closed state. In addition, the three-way valve 70 provided in each filtrate supply pipe 38 closes the path toward the branch pipe 50 instead of opening the path of the filtrate water supply pipe 38.

Then, the raw water flowing into the inlet pipe 10 is evenly distributed along the distribution pipe 30 provided in a circular shape on the lower filter chamber (S _f) is introduced into the filter chamber (S _f). In this process, heavy solids or relatively large contaminants contained in the raw water settle and accumulate on the bottom of the raw water induction pipe 28 and inside the filtration chamber sharing pipe 34, and light contaminants having a relatively low specific gravity are described above. It flows upward along the space between the filtration member 24 and the raw water induction pipe 28 and is integrated in the uppermost layer of the precipitation concentration chamber Sc in the treatment tank 12.

At the same time, the raw water in the filtration chamber (S _f ) is filtered while passing through the filtration membrane of the filtration member 24 in the process of flowing along the space between the filtration member 24 and the raw water induction pipe 28. The filtered contaminants are attached on the outer surface of the filtration membrane, and water is introduced into the filtration member 24 through the filtration membrane.

AOP process

The filtered water filtered by the filtration member 24 is introduced into the overflow chamber (So) along the filtered water supply pipe 38 connected to the drainage end (D) of each unit filtration module, and the introduced filtered water flows upward. Ultraviolet rays are irradiated by the ultraviolet lamp unit 40 installed therein while being exposed to ozone which is finely diffused through the ozone diffuser 54 and sterilized and purified.

More specifically, as the washing pump P3 is started, a part of the filtrate in the filtrate sharing pipe 66 flows in the direction of the arrow along the backwashing tube 68 to the branch sharing tube 56. At this time, the three-way valve 70, as shown in Figure 14, instead of closing the path of the seven filtered water supply pipe 38, the path toward the one branch pipe 50 is open, the back washing pipe ( 68, the filtered water flowing through the branched pipe 56, a part flows into any one of the open filtered water supply pipe 38 for cleaning the specific filter member 24, and part of the ozone injection pipe 52 In this case, ozone is introduced from the ozone supply pipe 48 by the Venturi effect caused by the pressure difference generated when passing through the injector placed on the path of the ozone injection pipe 52. As a result, the introduced ozone is mixed with the filtered water and injected into the overflow chamber So through the ozone diffuser 54 installed at the end of the ozone injection pipe 52.

As described above, the purified water treated by the AOP process overflows the upper end of the first cylindrical partition 18 and flows into the balancing tank Sv, and is then stored in the bottom of the balancing tank Sv. The water is discharged in a subsequent process along the discharge pipe 62 connected to it. In this case, the circulation pump P2 may be selectively operated.

Cleaning process

According to the present invention, while filtering the water as described above, the plurality of filtration members 24 may be sequentially cleaned for each filtration module.

Specifically, a three-way valve 70 installed in the filtrate supply pipe 38 connected to a specific unit filtration module requiring cleaning while the raw water is filtered is driven in a state as shown in FIG. 15. That is, the three-way valve 70 opens the path with the branch pipe 50 instead of closing the path of the filtered water supply pipe 38.

Then, a part of the filtrate sucked from the filtrate sharing tube 66 through the backwash tube 68 according to the operation of the washing pump P3 is washed with the corresponding branch pipe 50 and the filtrate as shown by the arrow of FIG. 15. The feed pipe 38 is sequentially flowed back and flows into the filtration member 24 through the drain stage D of the unit filtration module.

As described above, the filtered water flowed back to the inside of the filtration member 24 to remove the contaminants adsorbed on the outer surface of the filtration membrane while flowing from the inside of the filtration membrane, and the dropped contaminants are mixed water of the incoming raw water and the backwash water It is discharged out of the raw water induction pipe 28. That is, the raw water received through the inlet pipe 10 into the filtration chamber S _f and the backwash water spouted from the inner surface of the filtration member 24 by flowing the filtrate water supply pipe 38 back to the filtration chamber S _f) some errors W flow into each other in the (S _f) to flow into the other filter chamber (S _f) adjoining on a shared W that is in communication with the lower error pipe 34 while the remaining portion has the filter chamber (S _f Flows together with the contaminants concentrated in the upper part while falling into the space between the filtration member 24 and the raw water induction pipe 28 of the) and discharged to the top of the raw water induction pipe 28 and then settles downward. It is accumulated at the bottom of the precipitation concentration chamber (Sc).

On the other hand, the three-way valve 70 installed in the filtered water supply pipe 38 of the remaining unit filtration module that is not cleaned, as described above, the path of the filtered water supply pipe 38 is still open and the path of the branch pipe 50 is closed. Is kept.

Therefore, as described above, the filtered water flowing along the backwash tube 68 flows through the branch injection pipe 56 and flows inside the ozone injection pipe 52, so that the inflow and injection of ozone can be continued.

As described above, while one unit filtration module is cleaned, the filtration process is continuously performed in the other unit filtration module, and after one time of cleaning is performed for one unit filtration module, a three-way valve of another adjacent unit filtration module is performed. The cleaning proceeds sequentially while the 70 is operating.

Light pollutant removal process with low concentration and discharge of concentrated water

When contaminants are concentrated in the precipitation concentration chamber Sc during the raw water treatment as described above, the discharge valve M2 is opened manually and the contaminants are discharged.

In addition, the weight of the solid precipitated in the bottom of the raw water induction pipe 28 constituting the filtration chamber (S _f ) and the filtration chamber shared pipe 34 connected to the path of the solid discharge pipe 36 manually or automatically if necessary Opening the valve (M3) posted on the top is to discharge the heavy solids with water to the discharge pipe (16).

In addition, as described above, in the continuous flow, sequential washing type composite water treatment apparatus according to the present embodiment, a light pollutant having a relatively low specific gravity accumulated on the top layer of the precipitation concentration chamber Sc as the operation time passes is also required. Or it is automatically discharged with water by opening the discharge valve (M4) posted on the path of the overflow pipe (60).

The discharge of contaminants in the precipitation concentration chamber (Sc), the discharge of the weight solids precipitated in the raw water induction pipe 28 and the filter chamber shared pipe 34 and the light pollutant discharge process with a small specific gravity through the overflow pipe (60) Since the same as in the above-described embodiment, further detailed description will be omitted.
