Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for purifying and purifying liquids, mainly water (including safety treatments such as sterilization and algaecide), and adjusting the composition and quality. .

C. Prior Art] Equipment for refining, purifying, composition, and quality adjustment of liquids, mainly water, has been used since ancient times when treating water by adding a flocculant to the liquid to be treated and using mechanical stirring. The suspended matter, colloidal substances, etc. in the water are aggregated, and the precipitate and water are separated by sedimentation and separation using their own weight, or by adhesion of air bubbles and 1.1 separation, etc., and then the starting grains are separated. A clear purified filtrate is obtained by passing water through a sand filter filled with sand of a uniform diameter and removing any remaining fine precipitates. For further purification, water is passed through an activated carbon adsorption filter filled with granular activated carbon to adsorb and remove organic substances.

In addition, for sterilization and algaecide treatment, appropriate chemicals such as chlorine agent 1 are used before and after flocculation treatment or before and after filtration treatment.
Treatment is carried out by adding bisulfites, sulfites, peroxides, heavy metal salts, etc. In addition, as a device for adjusting the composition of the liquid, an ion exchange resin tower filled with ion exchange resin is installed after the activated carbon adsorption filter, or after the sand filter depending on the water quality, to remove hardness components in the water to be treated. It has been practiced to soften the water by adsorption, or to convert it into pure water by adsorbing and removing cations and anions in the water. In recent years, the thermal evaporation method has been adopted as a method for desalinating seawater in the Middle East, and the concentration of salinity is several 1.
It is about 0 ppm, and is it reverse immersion? In the production of fresh water using the first method, the concentration of ions such as calcium is usually low, even at a degree S of several hundred to several tens of ppm. Drinking such fresh water is not necessarily healthy or desirable. For this purpose, we use a slaked lime slurry injection device to supply HFI calcium ions, or we adjust the hardness by passing water through a packed tower filled with limestone while supplying carbon dioxide gas.
It adjusts the liquid properties. In this way, the media that perform each function and effect are independent devices, and by appropriately arranging the devices, L1-like processing can be performed.

Even in the case of small capacity, it is common to miniaturize and arrange the devices as described above. Furthermore, water purifiers have become popular in recent years as a representative example of small capacity water purifiers, but these f% water purifiers have five filter media such as ceramic or nonwoven fabric, activated carbon adsorbent, ion exchange resin, etc. replaced in one device. Select and combine one or more media such as adsorbents, water quality adjusting materials such as marble, maifan stone, limestone, etc., and store them in a single container in a layered manner in the direction of liquid flow. or concentrically stored so that the liquid flows through each medium in sequence, during which purification, purification, or water quality adjustment can take place. When storing these media, the media are stacked directly or through a porous fluid, or are arranged concentrically through partition walls, making it impossible to take out only a specific media from the system. It is structured like this.

[Problem that the invention seeks to solve]

In the present invention, a plurality of media having different processing effects are arranged in a single device having a supply port for the liquid to be treated and a discharge port for the treatment liquid so that they can be exchanged independently. That is, with the exception of special media, these media have a limited lifespan, and there is a limit to the refining and purifying capacity per unit weight. The amount of each medium stored in the device is determined based on the standard quality of water to be treated, and the media can be mixed directly or through a porous fluid in one container. Once the initial amount of fuel has been purified and purified, the entire container is replaced with a new one. However, in practice, it is common for the quality of the water to be treated to vary regionally, temporally, and seasonally, so that all the media used reach their full potential at the same time and have a long lifespan. Even when some products reach the end of their lifespan, others often still retain sufficient refining ability. Even in such a case, it is extremely uneconomical to replace them all at once with new ones, and it is also undesirable from the standpoint of resource conservation.

In the present invention, although there is no difference from the conventional method in that media with different functions and effects are stored in one container, the media with different lifespans can be replaced independently with new media. It is.

[Means for Solving the Problems] The present invention provides physical, chemical, biological Two or more media selected from a group of media that act on biological, sterilizing, and algaecide are arranged in multiple stages in the axial direction of fluid flow, and at least one of the media is non-fluid and can be detached. A fixed medium is used, the liquid to be treated is passed through the first stage medium, and the processing liquid from the first stage is sequentially passed through the next stage medium. That is, all the media are not fluid media, but non-fluid fixed media that can be attached and removed as appropriate are used, and these media are arranged in the axial direction.

[Effect]

Next, the operation of the present invention will be described. In the first illustrated example, the container 1 is connected to a chamber A by a partition wall 4 in which a through hole 5 is formed.
A pleated type filter body 15 which performs a physical filtration action is housed in the chamber A. A pleated filter is one of the widely used filtration media, which is made by folding a flat membrane into pleats and placing a filtrate collection pipe in the center, and fixing and sealing both ends with a suitable resin. It is. Room B
A pleated filter body with a smaller porosity is housed in the holder. Thus, by arranging it in the axial direction of fluid flow, I+! filtered filtrate.

Furthermore, by filtering through the Δl passage body housed in the firebox, it becomes possible to reduce the load of suspended solids on the filter body in chamber B very easily. In such an arrangement, the filter element entering the chamber is generally more likely to be loaded with suspended solids, and pressure loss is likely to increase due to filtration surface contamination, which increases the frequency of replacement. The filter body for the chamber and the filter body for the chamber B are housed independently, and since they are removable filter bodies, they can be replaced completely independently. At the time of replacement, the pleated filter body 15 can be easily taken out of the system by removing the threaded portion between the container 1 and the end plate 2, and can be replaced with a new filter body. The filter in chamber B can be replaced very easily by turning the end plate 3 and unscrewing it, and it can be removed and replaced with a new one.

The examples illustrated in FIGS. 2 and 3 also have the same effect as the example illustrated in the first diagram. The examples shown in FIGS. 4 and 5 are similar to the first example in which the medium is arranged in the axial direction, which is the flow direction of the fluid.
In the example shown in the fourth figure, the filtrate of the filter body in the chamber is sent to the membrane cartridge in chamber B via a packed bed containing a disinfectant as a medium, and the filter body and the membrane cartridge are independent from each other. You can then exchange it for a new one. To replace the filter, see Figures 1 and 2.

Although there is no difference from the example shown in the third figure, the membrane cartridge can be easily removed from the end plate 3 by imitating the outer circumferential wall of the water collection chamber 45 which is screwed onto the end plate 3.

In the example shown in the fifth diagram, the filtrate that has passed through the non-flowable fixed filter in chamber A is passed through the granular activated carbon bed, which is a fluid medium forming a packed bed in chamber B, and then processed. The permeated liquid is allowed to pass through the water collection chamber 45 and into the sterilizer-filled bed in the chamber.
The filter body in chamber C and the membrane cartridge in chamber C can be replaced completely independently. The adsorption medium in chamber B can also be replaced with a new one when the threaded portion of end plate 2 is removed and the filter in chamber A is replaced.

〔Example〕

The first illustrated example is an example in which pleated filters with different porosity are arranged in one container in the axial direction.

First, the container 1 has a partition wall 4 having through-holes 5 through which fluid can flow.
It is divided into two chambers, chamber B and chamber B.

In chamber A, a pleated filter body 15 with a porosity of about 2.5 to 5 μm is housed, with the ends of the filter medium fixed with resin end plates 16 and 17, and in chamber B, the ends of the filter medium are fixed with resin end plates 16 and 17. End plate 2
Pore 1a 0.2-0.1 μm fixed with 9.30
A micro filtration membrane mounting body 28 of approximately 100 cm is housed therein. The pleated filter body 15 and the microfiltration membrane mounting body 28 are connected to the resin end plate 17 in the partition wall 4. and 29 through respective nozzles 22,23.

The treated water is fed into the chamber A from the supply port 6 by an appropriate water feeding means, filtered on the filter surface 18 of the pleated filter body 15, and the filtrate passes through the strainer 20 perforated in the wall of the perforated pipe 19. Collect water in water collection pipe 21 5 Resin end plate 1
The membrane of the microfiltration membrane attachment 28 passes through a series of channels consisting of the nozzles 22 of 7, the through-holes 5 of the partition wall 4, and the nozzles 23 of the resin end plate 29 of the microfiltration membrane attachment 28 housed in the chamber B. It reaches surface 25. Here, the filtrate of the pleated filter body 15 is filtered on the I membrane surface 25 and discharged from the strainer 27 which is perforated in the perforated pipe 26 and collected while being discharged to the outside of the system from the outlet 8. Ru. That is, it is possible to remove coarse particles by filtration using the filter at the front stage, and remove fine particles from the filtrate using the removal and removal body having more fine pores. Furthermore, the water pressure applied to the water supplied to chamber A simultaneously performs filtration in the first stage and membrane separation in the second stage, making it possible to use energy effectively.

In addition, in this embodiment, the water to be treated flowing in from the supply port 6 to the station building where the valve material drainage lower is closed by the valve is
By opening this valve at 1 o'clock, it is also possible to remove the particle-containing liquid that is to be filtered and is concentrated on the filter surface 18 in chamber A. In addition, by constantly removing part of the particle-containing liquid, it is possible to maintain the particle concentration of the particle-containing liquid near the filter medium surface at a constant concentration, and in this way, clogging of the filter medium can be significantly reduced. Since this can be prevented, it is possible to suppress the ilt overresistance caused by clogging to a low level, and the frequency of filter replacement is also reduced.

Also, in chamber B, a valve material drain port 9 is provided in the same manner as in chamber A, and if used in the same manner as described above, membrane separation can be performed effectively in the same way.

Now, depending on the quality of the water to be treated, if a certain amount of water is filtered, the surface and pores of the filter body will be contaminated, pressure loss will increase, and the number of water escaping can only be achieved at a limited pressure. I won't be able to do it. In this case, an end plate 2 fitted to the end of the container 1,
3 and remove pleated filter body 15. in chamber A. The microfiltration membrane attachment 28 in chamber B can be taken out separately and replaced with a new one. The filtrate is watertightly sealed in the through-hole 5 of the partition wall 4 by a sealing material 11, 12 (for example, an O-ring), completely preventing liquid leakage, and the end plate 3 and the microfiltration membrane mounting body 28 are made of resin. End plate 30
A sealing material 14 is also installed between the nozzle and the nozzle attached to the center, completely preventing liquid leakage. Also container 1
end plate 2 and resin end plate 16 of pleated filter body 15, and end plate 3 and resin end plate 30 of microfiltration membrane mounting body 28.
The inner sides of both ends of the container 1 and the end plates 2 and 3 are mutually fitted so that the filter body and the detachable body can be sufficiently pressed against the partition wall 4. It can be screwed on, and sealing material 10.13 can be used to prevent liquid leakage outside the system.
completely blocked by.

The fitting between the inner sides of both ends of the container 1 and the end plate 2.3 is not limited to screwing as described above, but may be performed using bolts using flanges, Nand fastenings, Victoric joints, or any other method. You may do so.

The second illustrated example is an example in which a pleated filter with a porosity of about 4 to 5 μm and a spiral ultrafiltration membrane module are arranged in one container in the axial direction.

The container 1 is divided into a chamber A and a chamber B by a partition wall 4 having through-holes 5 through which fluid can flow. Inside chamber A, there is a filter with a porosity of 4 in which the end of the filter medium is fixed with a resin end plate 16.17.
A pleated filter body 15 of approximately 5 μm is housed in chamber B.
Inside is a spiral-type ultrafiltration system that is wound in a glue-like manner around a perforated tube 26 that is watertightly sealed so that the open end of an envelope-shaped ultrafiltration membrane sealed on three sides communicates with a strainer 27. A membrane module 33 is housed. The pleated filter body 15 and the spiral ultrafiltration membrane module 33 have a nozzle 22 attached to the center of the resin end plate 17 in the partition wall 4, and a nozzle 22 attached to the end of the porous tube 26 of the membrane module. The dispersion end 31 is in communication with the dispersion end 31 . Furthermore, the resin end plate 1G of the pleated filter body 15 is fitted with the end plate 2 screwed onto the inside of the end of the container 11, while the lower end of the porous tube 26 of the spiral ultrafiltration membrane module 33 The end plate 3 is fitted to the inner end of the container 1 through a sealing material 14. Moreover, the filter body and membrane module are sufficiently held down and fixed toward the partition Ii4 by screwing the inner sides of both ends of the container 1 with the end plates 2.3.

Now, the water to be treated is fed into the chamber A from the supply port 6 by an appropriate water feeding means, and the filter medium surface 18 of the pleated filter body 15 receives the water from d! The filtrate is collected into the tube through a strainer 2o that is perforated in the wall of the porous tube 19, and the resin end plate 17
The spiral-wound membrane module 33 is wound through a series of channels consisting of the nozzle 22, the through-hole 5 of the partition wall 4, and the dispersion end 31 attached to the end of the perforated tube 26 of the membrane module housed in chamber B. Water is fed to the membrane surface from the open end 32 of the shape. The U-shaped band 36 is a type of watertight seal provided so that all the fluid flowing into the chamber B is sent to the membrane surface through the open end 32. The filtrate sent to the membrane surface passes through the membrane while flowing along the membrane surface in the axial direction, and is collected as membrane-permeated water in the strainer 27, which is a porous tube communicating with the membrane permeation side. The collected membrane permeate water is transferred to the end plate 3.
It is discharged out of the system from an outlet 8 attached to the . In this way, in this embodiment, the water to be treated fed from the supply port 6 is filtered to remove fine particles and colloidal substances present in the water by the filter in the chamber A, resulting in extremely clear filtrate. None, after which water is sent to the ultrafiltration membrane module to reduce contamination of the ultrafiltration membrane as much as possible.
The effect can be fully exhibited.

Also, in this embodiment, the valve material drainage lower, 9
It is also possible to operate with the valve closed or open, and the effect is the same as in the first illustrated example.

Particularly in the case of the membrane surface of the ultrafiltration membrane in chamber B, some of the concentrated liquid may be continuously discharged from the valve material drain port 9 to the outside of the thread 111, or temporarily discharged at an appropriate frequency to prevent membrane contamination. It can be reduced. When the valve material drain port 9 is opened, the spirally wound open end 32 of the spiral membrane module 33
The fluid flowing in from the opening passes through the membrane and is collected in the porous pipe 26, and the partially concentrated fluid is drained from the other open end to the outside of the system from the valve material drain port 9 as shown by the dotted line. is discharged to.

The third illustrated example is an example in which a spiral type ultrafiltration membrane module and a spiral type reverse osmosis membrane module are arranged in one container in the axial direction. The membrane modules housed in chambers A and B are spiral-wound membrane modules similar to the membrane module in chamber B in the second illustrated example. Although there are differences in membrane characteristics between ultrafiltration membranes and reverse osmosis membranes, the basic module structure is the same. The water to be treated is supplied to the spiral ultrafiltration membrane module 34 from the supply port 6 through the dispersion end 31 attached to the tip of the porous pipe 26 of the spiral ultrafiltration membrane module 34 by an appropriate water supply means.
Water is sent to the membrane surface from the open end 32 of the pastry roll. Note that the water to be treated that has flowed into the chamber A is prevented from flowing into the cavity formed between the membrane module and the container 1 by the U-shaped band 36 having a sealing effect, and all of the water to be treated is Water is fed from the open end 32 onto the membrane surface.

The water to be treated that has been sent to the membrane surface passes through the membrane while passing through the membrane surface in the axial direction, and is collected as primary membrane-permeated water in the strainer 27 of the porous tube 26 that communicates with the membrane permeation side. The collected membrane-permeated water is sent to the spiral type reverse osmosis membrane module 35 housed in the chamber B via the through-dε hole 5 of the partition wall 4 and further through the dispersion end 31 of the membrane module in the firebox. . The physical action of the membrane module in chamber B is exactly the same as the spiral type ultrafiltration membrane module 33 in chamber B in the second illustrated example, but since a reverse osmosis membrane is used, solutes can be removed. In order to prevent concentration polarization at the membrane surface due to solute concentration, the valve material drain port 9 is always open and a part of the concentrated water is continuously drained out of the system to perform effective membrane separation. I can do it. Note that the U-shaped band 36 also has a sealing effect similar to the U-shaped band described above, and prevents fluid from flowing through, allowing all the fluid flowing into the chamber B to flow from the open end 32 of the membrane module to the membrane surface. It looks like this.

The fourth illustrated example is an example in which a pleated filter, a sterilizer-filled layer, and a hollow fiber ultrafiltration membrane module are arranged in one container in the axial direction. The container 1 is bisected into a chamber and a chamber B by a septum 4 having a through-hole 5 through which fluid can flow. The filter bodies stored in the chamber A are the first illustrated example and the second illustrated example.
Like the filter stored in chamber A in the illustrated example, it is a pleated type filter, and its porosity is about 4.5 μm.

The resin end plate 16 is fitted with the end plate 2 which is screwed into the case 8:+1, and one of the resin end plates 17 is fitted.

Through the sealing material 11 and the inner wall of the cylindrical container 38 forming the iodine adsorption medium (sterilizer) filling layer 41.

Fitted watertightly. The structure of the medium in the cylindrical container 38 includes, from the fluid supply side, a filter cloth 4o having communicating holes vertically and horizontally;
Next, an iodine adsorption medium (e.g. iodine adsorption resin) packed bed 4
1. The safety filter 42 has a porosity of about 25 μm. The cylindrical container 38 is tightly adhered to the support 37 and the partition wall 4, and is fixed inside the container 1 via the support 37. It may be made removable. A hollow fiber type ultrafiltration membrane module 43 is housed in the chamber B, and the membrane permeation side of the hollow fiber communicates with the water collection chamber 45 through its open end. The open ends of the hollow fiber groups are bundled and fixed by a tube sheet 44, and the periphery of the tube sheet 44 is watertightly bonded to the inner wall of the water collection chamber 45.

Now, the water to be treated flows into the chamber A through the supply port 6 and is filtered on the filter medium surface 18 of the pleated filter body 15, and the filtrate passes through the strainer 20 perforated in the perforated pipe 19 and collects in the pipe. . The collected filtrate flows into the dispersion chamber 39 of the cylindrical container 38 through a flow path bored in the center of the resin end plate 17, and is further filled with r+M, cloth/10. Microorganisms leaking from the i1 supernatant are removed to the iodine adsorption medium packed bed 41, and substances that may damage the membrane surface are removed by the safety filter 42. Note that the safety filter 42 is provided for the purpose of protecting the membrane, and is not intended for filtering out single particles. The sterilized water that has passed through the security filter reaches the chamber B via the through hole 5 of the partition wall 4, passes through the membrane surface of the hollow fiber ultrafiltration membrane module 43, and collects in the water collection chamber 45 from its open end. The water is drained and discharged from the outflow port 8 to the outside of the system. The functions and effects of the valve seal drainage lower 9 are the same as those described in the first illustrated example and the second illustrated example. Note that some sterilizing media filled in the cylindrical container 38 have a long-lasting sterilizing effect, and if such media are used, there is no need to replace them. Only the ultrafiltration membrane module 43 needs to be replaced. When replacing the pleated filter body 15 with a new filter body, the capacity v!
By turning the end plate 2 screwed onto the end of the resin end plate 1 and pulling it with the resin end plate 16, one of the resin end plates 17 will be released from the sealing material 11 and can be pulled out of the system. Just install a new one. Furthermore, when replacing the hollow fiber type ultrafiltration membrane module with a new one, by turning the water collection chamber 45 that is screwed onto the end plate 3, both the tube sheet 44 and the tube sheet 44 can be removed from the system, and a new one can be replaced instead. Just attach the membrane module. This replacement operation can be performed at the same time, or can be performed separately at appropriate frequencies depending on the degree of contamination.

The fifth illustrated example is an example in which a filtration bed, an activated carbon packed bed, a hollow fiber type ultrafiltration membrane module, a sterilizing agent packed bed, etc. are disposed in one container in the axial direction. The volume rjt1 has through-holes 5.5', 5' through which fluid can flow, and partition walls 4.4', 4' having through holes 5', 5' through which fluid can flow.
It is divided into four rooms, A, B, C, and D. The filter body installed in the chamber A is a depth type filter cloth 40 having communicating holes vertically and horizontally, and behind it is a support layer 46 of about 100 mesh. These filter bodies are supported by partition walls 4. The next chamber B is a bed 47 filled with granular activated carbon, which adsorbs and removes free #L elements, organic substances, and off-flavors in the filtrate supplied through the through-holes 5.

Prevent contamination of the ultrafiltration membrane surface in chamber C. In room B,
Organic or inorganic adsorbents such as organic matter adsorption resin, diatomaceous earth 5-alumina, etc. can also be used. Moreover, its form may be granular, powdery, or fibrous, and it can be used without any restrictions. Furthermore, the fluid passes through a safety filter 42 with a porosity of about 25 μm, and further flows through the through-holes 5' of the partition wall 4', and enters the chamber C.
flow inward. Here, hollow fiber ultrafiltration membrane module 4
The membrane permeation side of No. 3 is open toward the water collection chamber 45,
It communicates with the firebox through a partition wall 4' having through-holes 5''.The chamber is filled with an iodine adsorption medium having sterilizing properties.

Now, the water to be treated flows into the chamber A through the supply port 6, passes through the filter cloth 40, further passes through the support layer 46, and then flows into the chamber as a clear filtrate. Here, while passing through the granular activated carbon packed bed 47, dechlorination and removal of off-flavors and tastes are accomplished. In this way, the adsorption treated water passes through the safety filter 42 and enters the hollow fiber type limit a'! !
It passes through the membrane surface of the r-membrane module 43, and during this time, fine particles, bacteria, and depending on the membrane characteristics, pyrogene, etc. are also removed. The membrane-permeated water is collected into the water collection chamber 45 from the open end of the hollow fiber opening into the chamber, and further passes through the through-hole 5' of the partition wall 4' to the iodine adsorption medium with sterilizing power supported by the support layer 46. It flows through the packed bed 41, passes through the filter cloth 40, and is discharged from the outlet 8 to the outside of the system.

The seal 10 is for preventing the water to be treated from leaking out of the system, and the seal 10' is for preventing the water to be treated from flowing into the chamber B without being filtered. The purpose of the sealing material 13 is to prevent the adsorption treated water from leaking out of the system, and the purpose of the sealing material 13' is to prevent membrane permeated water from leaking out of the system.

In this way, in the present invention, in one container.

Two or more layers of media are arranged in the direction of fluid flow, and one of these media is a removable non-flowable fixed media. The first illustrated example has two layers of media, but
In this example, both layers are made of removable non-flowable fixing media. Further, the second illustrated example also has two layers of removable non-fluid fixing media arranged in one container. The example shown in the third diagram is also similar to the example shown in FIGS. 1 and 2. In the example shown in the fourth figure, three layers of media are arranged in one container, but if the sterilizing agent packed layer acts like a zocatalyst in terms of sterilization, the container will remain in the container semi-permanently as in this example. A medium such as a pleated filter body or an ultrafiltration membrane module can be attached and detached as a non-flowable fixed medium. In the fifth illustrated example, a total of four layers of media are arranged in one container, and this inner chamber A
The filter body and the ultrafiltration membrane module in chamber C are removable non-flowable fixed media. In addition, the disinfectant-filled layer inside the room is semi-permanent, so there is no need to remove it and it can be used as is. Of course, the filling layer can also be made detachable if necessary.

In addition, in the first illustrated example, two media are used as filtration media, but one of them may be used as an adsorption medium, or both may be used as adsorption media, which may be selected as appropriate depending on the purpose, and if necessary, a more suitable medium may be used. They may be installed consecutively. The pleated filters in the second illustrated example and the fourth illustrated example can also be replaced with an adsorption medium as in the case of the city record, and when a removable non-flowing fixed medium is adopted as the medium, fibrous activated carbon, Fibrous ion exchange resins and the like are convenient.

In the example shown in the fifth figure, an iodine adsorption medium such as an iodine adsorption ion exchange resin is used as the disinfectant stored in the room, but other heavy metal carriers or heavy metals may be used, depending on the sterilization or sterilization effect. However, there are no restrictions on the medium or its form.

In the present invention, not only a medium with a sterilizing or bactericidal effect, but also a medium that supports living organisms can be used. For example, beneficial aquatic microorganisms are attached to activated carbon particles with an extremely large surface area, and a biofilm is formed. It is also possible to form and use this as a medium to decompose easily decomposable organic substances in water, and at the same time elute metabolic products into water to impart flavor to water. In addition, in the present invention, '! A magnet can also be attached as an adsorption medium, and it is also possible to effectively remove magnetic iron oxide, iron rust, etc. in the water to be treated. In addition, for the purpose of adjusting the liquid properties of water, adjusting mineral components, and adjusting useful ingredients, we also use artificial granules containing natural minerals, their burned products, animal bones, their burned products, and other useful ingredients. can also be used as a medium. Examples include limestone, calcined shells, calcined coral, calcined cow bones and fish bones, phosphate rock containing calcium phosphate, chemical fertilizers, calcined phosphorus fertilizers, and the like.

In addition, in the present invention, as shown in FIG.
Gender-fixing media can also be used.

In the second illustrated example, the pleated filter body of the second illustrated example is used as a fluid medium such as granular activated carbon or granular adsorption resin.

Alternatively, it can also be replaced with an ion exchange resin.

In such a case, it is not necessary to provide partition walls between the media. Note that fluidity in the present invention does not necessarily mean that the medium flows within the container (as in pleated filters, membrane modules, etc., where the medium is fixed without flowing due to the fluid). In other words, it should be understood as a non-fixed medium, and is usually used as a packed bed.In addition, a fluid medium is placed on the upstream side. place,
When a non-flowable fixed medium is provided on the downstream side, the non-flowable fixed medium can be housed in a cylindrical body for the purpose of preventing the flowing medium from directly contacting the periphery of the non-flowing fixed medium and adjusting the flow of the fluid. It is also possible to have a so-called guide tube serve as a partition wall.

In addition, in the present invention, when introducing the processing liquid from the medium in the previous stage into the supply port as the liquid to be supplied to the latter stage, the connector is a flow-through partition wall as shown in the examples shown in FIGS. 1 and 2. There may be one, or it may be a connecting pipe, but in that case, the first
In the illustrated example, the resin end plate 17 or 29. In the second illustrated example, the periphery of the resin end plate 17 needs to be in close contact with the inner circumferential wall surface of the container 1 in a watertight manner.

〔Effect of the invention〕

As described above, when using the system [11] of the present invention, each medium can be exchanged extremely easily and completely independently, so that the capacity of each medium can be fully or almost completely utilized effectively. It can be said that it is extremely economical. The medium is also axially disposed within the container;
In addition, the flow direction of the fluid is also axial, making it extremely easy to remove the fluid containing foreign substances concentrated by each medium from the system, and thus the extremely
It is a practically excellent device that can reduce the amount of red dyeing as much as possible, and can be said to be a new and useful invention.
