On the other hand, the air bubbles injected through the air diffuser 23 is covered by the raw water induction pipe 32 surrounding the filtration member 22 to flow upward.

In addition, as the suction force is transferred to the filtration member 22 by driving the filtration pump P2, the bundle of the membrane fibers 25 of the hollow fiber membrane module 26 is formed based on the central axis of the diffuser 24. Although it may be squeezed toward the engine 24, the net pressure of the air supplied from the air generator 40 and the mesh-type net 30 to protect the hollow fiber membrane module 26 to maintain the original state .

UV sterilization and disinfection process

The filtered water filtered by the filtration member 22 is introduced into the overflow chamber (So) along the filtered water supply pipe 46 connected to the drainage end (D) of the unit filtration module. Specifically, since the filtrate supply pipes 46 are independently connected to the plurality of unit filtration modules (7 in the present embodiment), the filtrate is connected to the filtrate through a filtrate supply pipe 46 corresponding to the number of unit filtration modules. It is supplied to 48, and then flows into the overflow chamber So.

The filtered water introduced through the bottom of the overflow chamber (So) is sterilized and disinfected while ultraviolet rays are irradiated by the ultraviolet lamp unit 50 installed therein while flowing upward.

The purified water treated as described above flows over the upper end of the cylindrical partition wall 20 and is temporarily stored in the balancing tank Sb and then discharged to the outside through the discharge pipe 18.

Preferably, the water discharged to the discharge pipe 18 may be connected to an RO device, or may be used as drinking water after being treated with ultrapure industrial water or chlorine.

Meanwhile, the complex water treatment apparatus according to the present embodiment may not include the ultraviolet lamp unit 50. In this case, sterilization and disinfection by the ultraviolet lamp unit 50 are omitted.

Cleaning process

According to the present invention, while filtering the water as described above, the plurality of filtration members 22 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 in the filtrate shared pipe 48 flows back through the corresponding filtrate supply pipe 46 according to the operation of the cleaning pump P3, and passes through the drain stage D of the unit filtration module. Flows into). At this time, the filtered water introduced into the filtration member 22 will be referred to as 'backwash water'.

As described above, the backwash water flowed back into the filtration member 22 desorbs contaminants adsorbed on the outer surface of the filtration member 22 while flowing from the inside of the filtration member 22 to the outside.

The contaminants thus detached are mixed with the incoming raw water and the backwash water and discharged out of the raw water induction pipe 32. That is, the raw water obtained through the inlet pipe 10 into the filtration chamber S _f and the backwash water spouted from the inner surface of the filtration member 22 by flowing the filtrate water supply pipe 46 back to the filtration chamber S _f ) joins in part and flows through the distribution pipe 38 in communication with the lower part of the filtering chamber S _f to another adjacent filtering chamber S _f while the other part of the filtering chamber S _f As it escapes into the space between the filtration member 22 and the raw water induction pipe 32, it flows together with the contaminants concentrated in the upper part while being detached and discharged to the upper end of the raw water induction pipe 32.

On the other hand, when backwash water is supplied to the filtration member 22 and the contaminants adsorbed on the filtration member 22 are removed, air supplied from the air generator 40 is formed in the diffuser 24 of the filtration member 22. It is injected into the bubble state through the air diffuser 23 to apply a different pressure to the filter member (22). This leads to a drum effect of tapping the hollow fiber membrane module 26 of the filtration member 22 to more effectively remove the contaminants adsorbed on the outer surface of the filtration member 22. In addition, the sprayed bubble additionally adsorbs contaminants distributed in the water and flows upward along the space between the filtration member 22 and the raw water induction pipe 32 together with the floating contaminants, thereby allowing the raw water induction pipe 32. Is discharged to the top of the.

According to the invention, the filter chamber (S _f) the original error more than in the state that is defined by the feeding conduit (32) (S _f) the contaminants periodically, one feeding conduit (32 by sequential washing step was inside ), The concentration of the filtration chamber (S _f ) does not increase over time, thereby allowing continuous and effective filtration.

The contaminants discharged to the top of the raw water induction pipe 32 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 sedimentation concentration chamber (Sc) is separated by the raw water induction pipe 32 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 invention, the filtration process is continued in the remaining (6 in this embodiment) unit filtration modules while one unit filtration module performs the cleaning process. 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, the pressing force of the backwash water flowed back by the cleaning pump P3 in order to clean the filtration member 22 is applied to each filtration member 22 by the raw water inflow pump P1 or the filtration pump P2. It must be greater than the pressing force or suction force.

Condensate discharge and flotation separation process

If 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.

The discharge of the concentrated water may be performed in real time, wherein the real-time instantaneous concentrated water discharge is preferably equal to or less than the amount of raw water inflow introduced into the treatment tank 12 through the inflow pipe 10, and thus, the raw water inflow even 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 weight solids precipitate in the bottom of the raw water induction pipe 32 and the distribution pipe 38 constituting the filtration chamber (S _f ), if necessary, the valve M3 is opened manually or automatically, Together with the heavy solids are discharged to the discharge pipe (16).

Furthermore, in the complex water treatment apparatus employing the bubble effect and the raw water induction pipe according to the present embodiment, when the operation is started, air bubbles floating up to the uppermost layer of the precipitation concentration chamber Sc and light floating pollutants having a relatively low specific gravity are discharged in real time. It is discharged with water through (56). That is, the light floating pollutants having a relatively low specific gravity tend to accumulate on the top layer without being settled to the bottom of the sedimentation concentration chamber Sc. However, 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 small flotation pollutant having a small specific gravity can be discharged relatively easily through the discharge over pipe 56 and the discharge pipe 16 communicating with the outside.

2-2. Device behavior

Then, the preferred operation of the composite water treatment apparatus employing the bubble effect and the raw water induction pipe according to the present invention having the configuration as described above will be described. Similarly to the apparatus shown in FIG. 1, the complex water treatment apparatus according to the present embodiment performs an advanced treatment in which floating separation, sediment concentration, microfiltration, and sterilization / disinfection mechanisms for raw water behave in a complex manner.

Sediment Concentration and Filtration Process

First, when the raw water to be treated according to the inflow water conditions in the state in which the electric valve (M1) is open or the raw water inflow pump (P1) is driven, the raw water is processed along the inlet pipe 10 and the distribution pipe 38 It is introduced into the filtration chamber (S _f ) of each unit filtration module in the tank (12). At this time, the discharge valve (M2) and the valve (M3) is in a closed state. In addition, the flow path switching means 64 provided in each of the filtered water supply pipes 46 is in the filtration mode, that is, the state of Figs. 10 (a) and 11 (a).

Subsequently, in the filtration chamber S _f , heavy solids or relatively large contaminants contained in the raw water settle and accumulate on the bottom of the raw water induction pipe 32, and light contaminants having a relatively low specific gravity are filtered. It flows upward along the space between the member 22 and the raw water induction pipe 32 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 hollow fiber membrane module 26 of the filtration member 22 in the process of flowing along the space between the filtration member 22 and the raw water induction pipe 32. Is done. In the present embodiment, the filtration of the raw water is performed by the negative pressure method by the suction force of the filtration pump (P2). The filtered contaminants are attached on the outer surface of the filtration membrane, and water flows through the filtration membrane to the drain stage D formed at the top of the filtration member 22.

Meanwhile, as air is injected from the air generator 40 connected to the diffuser 24 of the filtration member 22 in the filtration process, contaminants contained in the water are adsorbed by air bubbles sprayed in a bubble state, thereby filtering the filtration member ( 22) and flows upward along the space between the raw water induction pipe (32). Therefore, the filtration performance can be improved more effectively.

UV sterilization and disinfection process

The filtrate filtered by the filtration member 22 is moved along the filtrate supply pipe 46 connected to the drainage end D of each unit filtration module, and then the filtrate common pipe 48, the filtration pump P2, and the filtrate supply pipe ( 46 ') is sequentially introduced into the overflow chamber So, and the filtered water is sterilized and disinfected by the ultraviolet lamp unit 50 installed therein while flowing upward.

The purified water produced by sterilizing and disinfecting the filtered water flows over the upper end of the overflow chamber So and is temporarily stored in the balancing tank Sb and then discharged to the outside through the discharge pipe 18.

Cleaning process

According to the present invention, while filtering the water as described above, the plurality of filtration members 22 may be cleaned sequentially or by a predetermined number of unit filtration modules at once.

Specifically, the flow path switching means 64 of the filtrate supply pipe 46 connected to the specific unit filtration module requiring the cleaning while the raw water is filtered is in a washing mode, that is, as shown in FIGS. 10 (b) and 11 (b). .

Subsequently, some of the filtrate (backwash water) stored in the filtrate shared pipe 48 according to the operation of the washing pump P3 shares the backwashing pipe 49 ', the washing pump P3, the backwashing pipe 49', and the backwashing water. The pipe 49 and the filtered water supply pipe 46 are sequentially flowed back, and are introduced into the filtration member 22 through the drain stage D of the corresponding unit filtration module.

As described above, the backwash water flowed back into the filtration member 22 desorbs contaminants adsorbed on the outer surface of the filtration member 22 while flowing from the inside of the filtration member 22 to the outside. Is discharged out of the raw water induction pipe 32 by the mixed water of the incoming raw water and the backwash water. That is, the raw water obtained through the inlet pipe 10 into the filtration chamber S _f and the backwash water spouted from the inner surface of the filtration member 22 by flowing the filtrate water supply pipe 46 back to the filtration chamber S _f ) joins in part and flows through the distribution pipe 38 in communication with the lower part of the filtering chamber S _f to another adjacent filtering chamber S _f while the other part of the filtering chamber S _f As it escapes into the space between the filtration member 22 and the raw water induction pipe 32, it flows together with the contaminants concentrated in the upper part while being detached and discharged to the top of the raw water induction pipe 32, and then settles downward. It accumulates on the bottom of the concentration chamber Sc.

At this time, the flow path switching means 64 provided in the filtrate supply pipe 46 of the remaining unit filtration module in which cleaning is not performed is still in the filtration mode, that is, in the states of FIGS. 10 (a) and 11 (a). As a result, the remaining unit filtration module that does not perform the cleaning is to perform the filtration process.

On the other hand, when backwash water is supplied to the filtration member 22 and the contaminants adsorbed on the filtration member 22 are removed, air supplied from the air generator 40 is formed in the diffuser 24 of the filtration member 22. It is injected into the bubble state through the air diffuser 23 to apply a different pressure to the filter member (22). This leads to a drum effect of tapping the hollow fiber membrane module 26 of the filtration member 22 to more effectively remove the contaminants adsorbed on the outer surface of the filtration member 22. In addition, the sprayed bubbles additionally adsorb the contaminants distributed in the water and flow upwards along the space between the filtration member 22 and the raw water induction pipe 32 together with the floating contaminants. Discharged to the top.

According to the invention, the filter chamber (S _f) the original error more than in the state that is defined by the feeding conduit (32) (S _f) the contaminants periodically, one feeding conduit (32 by sequential washing step was inside ), The concentration of the filtration chamber (S _f ) does not increase over time, thereby allowing continuous and effective filtration.

As described above, while one unit filtration module performs the cleaning process, 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, the other unit filtration module of the adjacent unit filtration module is performed. As the flow path switching means 64 operates, the cleaning proceeds sequentially.

Condensate discharge and flotation process

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 or automatically to discharge the contaminants.

In addition, since the solid weight precipitates in the bottom of the raw water induction pipe 32 and the distribution pipe 38 constituting the filtration chamber (S _f ), if necessary, by manually or automatically opening the valve (M3) by weight with water Solids are discharged to the discharge pipe 16.

Furthermore, as described above, in the complex water treatment apparatus employing the bubble effect and the raw water induction pipe according to the present embodiment, when the operation is started, bubbles rising to the uppermost layer of the precipitation concentration chamber Sc and light floating pollutants having a relatively low specific gravity It is discharged together with the water through the real-time discharge over pipe 56.

Emission of contaminants in the precipitation concentration chamber (Sc), discharge of the weight solids precipitated in the raw water induction pipe (32) and the distribution pipe (38), and of the light floating contaminants having a relatively low specific gravity through the discharge over pipe (56) Since the discharge process is the same as in the above-described embodiment, further description will be omitted.
