Description

  The present invention relates to an in-pipe purification device and an in-pipe purification system. More specifically, the present invention relates to an in-pipe purification device capable of satisfactorily fixing a carrier for supporting microorganisms and an in-pipe purification system using the same.

  Conventionally, sewage is transferred to a sewage treatment facility through a pipeline, and all sewage purification processing is performed at the sewage treatment facility. Therefore, in the sewage treatment facility, the equipment cost or equipment space accompanying the purification equipment is required.

  Therefore, in order to reduce the burden on the sewage treatment facility, a method for purifying sewage in the pipeline using microorganisms has been proposed. For example, International Publication No. 2013/172288 (Patent Document 1) describes an in-pipe purification apparatus having a structure in which an outer pipe is divided into an upper section and a lower section by a partition. The lower compartment is filled with a microbial carrier. This in-pipe purification device has a partition part provided with an opening, so that most of the solid matter in the sewage is transferred by the upper compartment, and sewage with a small content in the solid matter is supplied to the lower compartment. Therefore, stable sewage purification treatment can be performed. Furthermore, depending on the water level in the pipeline, the microcarrier can efficiently repeat the immersion with sewage and the exposure with air.

International Publication No. 2013/172288 Pamphlet

  In the above in-pipe purification apparatus, the outer tube is formed such that a protrusion protrudes from the inner wall. The partition has a curved portion that extends along the curved surface of the inner wall of the outer tube from both sides in the width direction, and the curved portion is formed in a shape that fits the protrusion on the inner wall of the outer tube. By such fitting, the partition is fixed to the outer tube.

As described above, in the above-described in-pipe purification apparatus, the outer pipe itself must be provided with a protrusion for fixing the partition. On the other hand, it cannot be stably fixed to a normal outer tube, that is, an outer tube having neither a concave portion nor a convex portion on the inner wall.
Therefore, an object of the present invention is to provide an in-pipe purification device that can be stably fixed to a normal outer tube.

The present inventor has found that the object of the present invention can be achieved by using a dedicated fixing member for fixing the member partitioning the inside of the pipe in the pipe, and has completed the present invention.
The present invention includes the in-pipe purification device described in (1) to (2) and (3) to (5) below, and the in-pipe purification system described in (6).

(1)
The in-pipe purification apparatus of the present invention should be installed in a pipe. The in-pipe purification apparatus includes a separator, a separator fixing member, and a carrier for supporting microorganisms.

The separator fixing member includes one separator contact portion, the other separator contact portion, and a pipe line contact portion. One separator contact portion is in contact with one of both sides in the width direction of the separator, and the other separator contact portion is in contact with the other of the both sides in the width direction of the separator. The pipe line contact part is provided between one separator contact part and the other separator contact part, and contacts the upper inner wall surface of the pipe line.
A carrier for supporting microorganisms is accommodated in the separator.

Thus, since the separator fixing member is interposed between the separator to be disposed on the lower inner wall surface of the pipeline and the upper inner wall surface of the pipeline, the in-pipe purification device is provided with a recess on the inner wall. It can be stably fixed to a normal pipe line in which no convex portion is formed.
Of the inner wall surface of the pipe, the region where the separator is disposed is referred to as a lower inner wall surface, and the other region is referred to as an upper inner wall surface.

(2)
The pipeline contact portion of the separator fixing member may have a curved surface along the upper inner wall surface of the pipeline.

  With this configuration, since the ground contact area between the pipe contact portion of the separator fixing member and the upper inner wall surface of the pipe can be increased, the in-pipe purification device can be more stably fixed to the pipe. be able to.

(3)
Another in-pipe purification apparatus of the present invention is an in-pipe purification apparatus installed in a pipe line. This in-pipe purification apparatus includes a plurality of separators, a joint portion, a separator fixing portion, and a carrier for supporting microorganisms.
The separator includes a support part and a partition part. The support portion has a surface along the lower inner wall surface of the pipe line. The partition part partitions the inside of the pipe and has a hole.
The joint portion connects the plurality of separators to each other.
The separator fixing part includes a pipe line contact part that is provided in the joint part and contacts the upper inner wall surface of the pipe line.
A carrier for supporting microorganisms is accommodated in the separator.

As described above, since the separator fixing portion is interposed between the separator inner portion and the upper inner wall surface of the pipeline, the in-pipe purification device can be used as a normal pipe in which neither a concave portion nor a convex portion is formed on the inner wall. It can be stably fixed to the road.
The joint portion and the separator fixing portion may be members that are separate and independent from each other, or may be integrally formed.

(4)
The joint part and the separator fixing part may be integrally formed.

  With this configuration, the fixing operation of the in-pipe purification device becomes efficient.

(5)
The pipe line contact portion may have a curved surface along the upper inner wall surface.

  With this configuration, since the ground contact area between the pipe contact portion of the separator fixing member and the upper inner wall surface of the pipe can be increased, the in-pipe purification device can be more stably fixed to the pipe. be able to.

(6)
The in-pipe purification system of the present invention includes a pipe and the in-pipe purification device described in (1) to (5) above. The in-pipe purification device is installed in the pipe so as to extend in the axial direction of the pipe.

  With this configuration, an in-pipe purification system is provided in which the in-pipe purification device is stably fixed to the pipe.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same elements are denoted by the same reference numerals, and their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[First Embodiment]
FIG. 1 is a schematic diagram of an in-pipe purification system using the in-pipe purification device of the first embodiment. FIG. 2 is a schematic external perspective view of the in-pipe purification device (part) of FIG. FIG. 3 is a schematic cross-sectional view taken along the plane including the line III-III in FIG. In the following, for the sake of convenience, the upward direction in FIG. 3 will be described as being upward, and the downward direction being downward. These directions (up and down directions) approximately coincide with the absolute direction when the in-pipe purification device is used, but do not necessarily mean the absolute direction when the in-pipe purification device is manufactured. Moreover, the part corresponded to the right-and-left end part of FIG.

[Basic configuration]
An in-pipe purification system 900 shown in FIG. 1 includes a pipe 910 and an in-pipe purification device 100 provided in the pipe 910. As shown in FIGS. 2 and 3, the in-pipe purification apparatus 100 includes a separator 200, a carrier 400 that should carry microorganisms, and a separator fixing member 500.

[Separator]
The separator 200 is a long body having a certain cross-sectional shape that extends in the axial direction of the pipe 910 (see FIG. 1). The length of the separator 200 in the axial direction corresponds to the length of the conduit 910. (In FIG. 2, for convenience, a part of this elongated body is displayed.) As shown in FIGS. 2 and 3, the separator 200 includes a support part 210 and a partition part 250. The support part 210 and the partition part 250 are integrally formed. As shown in FIG. 3, the cross-sectional shape of the separator 200 is axisymmetric about a straight line passing through the axis O of the pipe 910 and the lowest point of the pipe 910.

  As shown in FIG. 3, the support unit 210 has a concave curved surface 211 and a convex curved surface 212. Both the concave curved surface 211 and the convex curved surface 212 have a circular arc shape in cross section, and form a curved plate shape. The carrier 400 is fixed to the concave curved surface 211. The convex curved surface 212 is along a part of the inner wall surface of the pipe 910. Thereby, the separator 200 can be installed along the lower inner wall surface of the pipe line 910. Furthermore, the support part 210 has a deletion part 215 in the vicinity of the lowest point of the pipe line 910. The deletion part 215 is formed over the entire extending direction of the separator 200. As a result, the carrier 400 can be disposed from the missing portion 215 to the inside of the separator 200, so that the carrier 400 is easily disposed.

  The partition part 250 is a deformed plate-like perforated member in which water-permeable holes 254 (described later) are formed. As shown in FIG. 3, when the in-pipe purification device 100 is provided in the pipe 910, the partition unit 250 divides the space in the pipe 910 into a lower purification unit 911 and an upper flow rate securing unit 915. And divide into The partition part 250 is configured in a shape in which the center part (that is, the part on the target axis) is lower than the left and right side parts. In this embodiment, the partition part 250 has the flow velocity securing part 251 on the symmetry axis, and the pair of plane parts 253 and the pair of inclined parts 255 are arranged in this order from the side closer to the symmetry axis to the far side. Formed with. The pair of flat portions 253 and the pair of inclined portions 255 are respectively arranged in parallel with the extending direction of the separator 200.

  As shown in FIG. 3, the flow velocity securing part 251 constituting the lowest part of the central part of the partition part 250 constitutes the lowest part of the central part of the partition part 250, and its cross-sectional shape is convex downward. Is curved. With such a curved shape, a flow rate during a small amount of drainage in the pipeline is ensured.

  As shown in FIG. 3, a water-permeable hole 254 is formed in the flat portion 253. The water permeable hole 254 discharges the drainage to the purification unit 911 when the drainage in the flow rate securing unit 915 exceeds the capacity of the flow rate securing unit 251. A plurality of water permeable holes 254 are provided along the extending direction of the separator 200 (see FIG. 1). This imparts water permeability to the separator 200. In addition, since the flat portion 253 is flat in the horizontal direction, the workability of drilling the water permeable holes 254 is good during manufacturing.

  As shown in FIG. 3, the inclined portion 255 is formed so as to rise from the flat portion 253 toward the inner wall of the pipe line 910 and gradually rise along the inner wall surface. Thereby, it is easy to guide the waste water in the flow rate securing unit 915 to the purification unit 911, and it is easy to prevent clogging between the partition unit 250 and the inner wall of the pipe line 910. In the present embodiment, the shape of the inclined portion 255 is flat, but a curved shape that continues smoothly from the flat portion 253 so as to protrude downward from the flat surface of the inclined portion 255 shown in FIG. It may have a curved slope.

  When the support part 210 and the partition part 250 are configured as described above, the separator 200 is disposed below the center of the internal space of the pipe line 910 when provided in the pipe line 910 as shown in FIG. It is formed to occupy a part of the side. That is, the uppermost point of the separator 200 is formed so as to be positioned below the horizontal position of the axis O of the pipe 910 with a drop E therebetween. By separating the head E, installation in the pipe 910 is facilitated.

Separator 200 can be made of resin. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber.
For manufacturing the separator 200, a manufacturing method corresponding to the type of resin is selected. For example, in the case of a thermoplastic resin, it can be manufactured by extrusion molding. In this case, it can be manufactured by extrusion molding using a mold whose outlet shape is the same as the cross-sectional shape of the separator 200. In addition, for example, the exit shape is manufactured by extruding using a mold having a closed cross section composed of the support part 210 having no deletion part 215 and the partition part 250, and then forming the deletion part 215 by notching. Alternatively, extrusion may be performed using a mold having an annular outlet shape, and thereafter, forming into a closed cross-sectional shape constituted by the support part 210 and the partition part 250 without the deletion part 215 will be performed. You may manufacture by performing notch formation. For example, in the case of a thermosetting resin and FRP, it can be manufactured by a hand lay-up method, a pultrusion molding method, or the like.

[Carrier]
The carrier 400 is a wide elongated body extending in the axial direction of the pipe 910 (see FIG. 1). The length of the carrier 400 in the axial direction corresponds to the length of the conduit 910. As the carrier 400, a structure having a large specific surface area is used without particular limitation. For example, a porous material (for example, an inorganic porous body, an inorganic foam, a resin foam, etc.), a fibrous material (for example, a nonwoven fabric, a woven fabric, a single fiber body, a net-like body, etc.), a layered material (for example, a sheet laminate) Etc.). The fine pores of the porous material are preferably continuous pores. In the present embodiment, a resin foam is used. Examples of the resin include olefin resins (particularly polyethylene), urethane resins, vinyl chloride resins, acrylic resins, and the like.

  The shape of the carrier 400 is not particularly limited, and is a long body having a rectangular cross section in the present embodiment. The carrier 400 can be accommodated in the separator 200 by being fixed to the separator 200 with an adhesive, for example.

  The carrier 400 is fixed at a position where the height N of the narrowest portion in the purification unit 911 space can be secured. It is preferable from the viewpoint of preventing clogging between the carrier 400 and the partition part 250 that the narrowest part in the purification part 911 space secures the height N.

  The size (width w and height h in FIG. 3) of the carrier 400 in the pipe line 910 can be appropriately determined in consideration of the purification efficiency. In the present embodiment, the width w is 10% of the inner peripheral length of the conduit 910, and the height h is 2% of the inner peripheral length of the conduit 910.

  Within the pipe 910, the carrier 400 is disposed to face the surface connecting the axis O and the lowest position of the pipe 910. The arrangement position of the carrier 400 in the pipe line 910 can be determined in consideration of the purification efficiency and the like. For example, the separation distance i of the carrier 400 may be disposed so as to be 10% or more and 40% or less of the inner circumference of the pipe 910. The separation distance i being equal to or greater than the lower limit is that the flow rate in the purification unit 911 is ensured even when the water level of the purification unit 911 is low, the carrier 400 is brought into contact with air, and clogging is prevented. From the viewpoint of obtaining good purification efficiency, the carrier 400 is effectively brought into contact with the waste water when the water level rises.

[Separator fixing member]
As shown in FIGS. 1 and 3, the separator fixing member 500 is configured to be interposed between the separator 200 and the upper inner wall surface of the conduit 910 and fix the separator 200 to the lower inner wall surface of the conduit 910. The
As shown in FIG. 3, the separator fixing member 500 has a shape approximately along the upper inner wall surface of the pipe 910, and the cross-sectional shape thereof is line symmetric with respect to the same axis of symmetry as that of the separator 200. Separator fixing member 500 includes separator contact portions 510L and 510R disposed at both ends thereof, and conduit contact portions 520L and 520R disposed between separator contact portions 510L and 510R.

  Separator contact portions 510L and 510R are formed in a shape along the surfaces of both side portions of separator 200 and are in contact with the both side portions. Pipe contact parts 520L and 520R are connected to separator contact parts 510L and 510R, respectively, are formed in a curved plate shape having a curved surface along the upper inner wall surface of pipe line 910, and come into contact with the upper inner wall surface. .

  As described above, the separator fixing member 500 is interposed between the separator 200 and the upper inner wall surface of the pipe line 910, and the separator 200 and the pipe line 910 at the separator contact portions 510L and 510R and the pipe line contact portions 520L and 520R, respectively. The separator 200 can be fixed in the pipe 910 by contacting the upper inner wall surface of the pipe 910. In the present embodiment, as described above, the separator 200 is formed so as to occupy a part below the center of the internal space of the pipe line 910 in the pipe line 910. 3 is preferable in that it prevents movement in the circumferential direction and / or movement in the upward direction from the position in FIG. Thereby, the performance during use of the in-pipe purification device 100 can be stably secured.

  FIG. 4 is a schematic cross-sectional view of the separator fixing member 500 before being disposed in the pipe line 910. As shown in FIG. 4, the separator fixing member 500 is formed in such a shape that at least a part of the separator contact parts 510L and 510R and at least a part of the pipe line contact parts 520L and 520R protrude outside the inner wall of the pipe line 910. It is preferable. For example, the pipe contact portions 520L and 520R have a curved shape having a radius of curvature equal to or larger than the upper inner wall of the pipe line 910, and the separator contact portions 510L and 510R are on both sides of the separator 200 to which they should contact. It may be formed so as to be separated from the width.

  The separator fixing member 500 shown in FIG. 4 is flexible so that the separator contact portions 510 </ b> L and 510 </ b> R are closer to each other than the width of both side portions of the separator 200 when installed in the pipe 910 in which the separator 200 is accommodated in advance. After being deformed, the pipe 910 is entered. At the time of this flexible deformation, the uppermost portion of the separator fixing member 500 (so that the increase in the vertical width due to the deformation of the separator fixing member 500 does not hinder the entry into the duct 910 in which the separator 200 is accommodated in advance) It is preferable that the non-contact part 530 is provided between the pipe line contact parts 520L and 520R. The non-contact part 530 should just be comprised in the shape (in this embodiment flat plate shape) which does not contact the upper inner wall surface of the pipe line 910 in the pipe line 910. FIG.

  When the separator fixing member 500 is configured as described above, the pipe contact parts 520L and 520R and the separator contact parts 510L and 510R are respectively arranged at the upper part of the pipe 910 when fitted in the pipe 910. A load that stretches against the inner wall surface and both sides of the separator 200 is applied, and the separator 200 can be stably fixed.

  However, the present invention does not require the separator fixing member 500 to be formed in a shape that protrudes outside the inner wall of the pipe 910 as shown in FIG. 4 before being disposed in the pipe 910. 3 may be formed in the shape shown in FIG. 3 (the shape that fits in the conduit 910).

  Note that an adhesive is interposed between the conduit contact portions 520L and 520R and the upper inner wall surface of the conduit 910 and / or between the separator contact portions 510L and 510R and both sides of the separator 200. However, the present invention does not specifically exclude an embodiment in which no adhesive is interposed.

Separator fixing member 500 can be made of resin. The resin may be the same as the resin constituting the separator 200 or may be different. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber.
For manufacturing the separator fixing member 500, a manufacturing method corresponding to the type of resin is selected. For example, a thermoplastic resin can be manufactured by injection molding. In the case of a thermosetting resin and FRP, it can be produced by a hand lay-up method, an RTM molding method, or the like.

[Separator joint]

Each has a deformed plate-like portion having a shape along the flow velocity securing portion 251, the pair of plane portions 253, and the pair of inclined portions 255 of the partition portion 250 so as to be fitted into the end portion of the separator 200 Furthermore, the curved plate-like portion having a shape along the support portion 210 is extended from both sides of the deformable plate-like portion so as not to obstruct the carrier 400.

  The protrusion 555 is formed as a protrusion that protrudes in the direction from the inside of the separator 200 toward the outside. The separators 200 are connected to each other by inserting the first insertion part 551 and the second insertion part 553 into the end part of the separator 200 and inserting the end face of the separator 200 into contact with the protrusion part 555. . In the present embodiment, when the separators 200 are connected to each other by the joint 550, the surface of the separator 200 (particularly, the upper surface of the partition portion 250) and the top surface of the protrusion 555 are flush with each other, so that the flow of drainage is not hindered. .

  In addition, although it is preferable that the adhesive agent is interposed in the contact part of the joint 550 and the separator 200, this invention does not specifically exclude the aspect in which the adhesive agent is not interposed.

However, as in a fifth embodiment described later (see FIG. 9 described later), the thicknesses of the pipe contact portions 520L and 520R increase as they approach the uppermost non-contact portion 530 from both sides of the separator 200. It may be formed.

The joint 550 can be made of resin. The resin may be the same as the resin constituting the separator 200 and / or the resin constituting the separator fixing member 500, or may be different. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber.
For manufacturing the joint 550, a manufacturing method corresponding to the type of resin is selected. For example, a thermoplastic resin can be manufactured by injection molding. In the case of a thermosetting resin and FRP, it can be produced by a hand lay-up method, an RTM molding method, or the like.

[Other Embodiments]
Hereinafter, the second to ninth embodiments having a deformed shape of the separator fixing member 500 will be described. In these other embodiments, differences from the first embodiment will be mainly described, and the description of the same points will be basically omitted. In the present invention, the first to ninth embodiments may be arbitrarily combined.

[Second Embodiment]
FIG. 6 is a schematic external perspective view of the in-pipe purification apparatus of the second embodiment. In the in-pipe purification apparatus 100a shown in FIG. 6, the separator fixing member (separator fixing part 500a) and the separator joint (joint part 550a) are integrated. The joint portion 550a connects the separators 200.

  The joint portion 550a has the same basic shape as the joint 550 (see FIG. 5) of the first embodiment, and includes a first insertion portion 551, a second insertion portion 553, and a protrusion 555a. . Separator fixing portions 500a are formed so as to form a closed cross section with the projecting portions 555a, with both side portions of the projecting portions 555a of the joint portion 550a as base ends. The separator fixing portion 500a has the same basic structure as the separator fixing member 500 except that the separator contact portions 510L and 510R (see FIG. 2) in the separator fixing member 500 of the first embodiment are omitted. The pipe contact portions 520aL and 520aR, which have both ends of the joint portion 550a as base ends and contact with a part of the upper inner wall of the pipe line 910 (see FIG. 3) in the circumferential direction, and the pipe line contact portions 520aL and 520aR, And a non-contact portion 530a provided therebetween.

The separator 200 is indirectly contacted through the joint portion 550a.

[Third Embodiment]
FIG. 7 is a schematic external perspective view of the in-pipe purification apparatus of the third embodiment. In the in-pipe purification device 100b shown in FIG. 7, the separator fixing member (separator fixing portion 500b) and the separator joint (joint portion 550a) are integrated, as in the in-pipe purification device 100a of the second embodiment. .

  Unlike the separator fixing part 500a (see FIG. 6) of the in-pipe purification apparatus 100a of the second embodiment, the upper non-contact part 530a is not formed in the separator fixing part 500b. A separator contact portion 500b is formed with a conduit contact portion 520b having a curved surface along the entire circumferential direction of the upper inner wall surface of the conduit 910 (see FIG. 3). Therefore, the separator 200 can be fixed more stably via the joint portion 550a in that the ground contact area to the upper inner wall surface of the pipe line 910 can be increased.

Thereby, the ground contact area to the pipe line 910 can be more efficiently ensured, and the in-pipe purification apparatus 100d can be more stably fixed.

  As in the third embodiment, the separator fixing portion 500d may have a curved surface along the entire circumferential direction of the upper inner wall surface of the conduit 910 without forming the non-contact portion 530d. Similarly to the form, the non-contact part 530d may not be formed but may be deleted.

[Sixth Embodiment]
FIG. 10 is a schematic exploded view of the main part of the in-pipe purification apparatus of the sixth embodiment. FIG. 10 shows the joint portion 550e and the separator fixing portion 500e. The joint portion 550e and the separator fixing portion 500e are separate and independent members. FIG. 11 is a schematic external perspective view of the in-pipe purification apparatus 100e of the sixth embodiment.

  The joint portion 550e includes a first insertion portion 551 and a second insertion portion 553 similar to the joint 550 (see FIG. 5) of the first embodiment, and a protrusion 555e formed at a boundary portion thereof. The protrusions 555e are formed as protrusions that protrude in the direction from the inside of the separator 200 to the outside, but the missing portions 556L and 556R are generated on both sides of the joint portion 550e.

Separator fixing portion 500e includes joint contact portions 506L and 506R that are in contact with both side portions of joint portion 550e, and conduit contact portions 520aL and 520aR disposed between joint contact portions 506L and 506R. The joint contact portions 506L and 506R are formed in a shape that compensates for the missing portions 556L and 556R of the protrusion 555e in the joint portion 550e.

The joint contact portions 506L and 506R of the separator fixing portion 500e can be fitted in this recess. Thereby, even if the joint part 550e and the separator fixing part 500e are separate and independent members, they can be stably coupled to each other. Further, the pipe line contact portions 520aL and 520aR are in contact with the upper inner wall surface of the pipe line 910. Therefore, the separator 200 can be indirectly fixed via the joint portion 550e.

In the present embodiment, the carrier fixing member 300i is formed so as to constitute a deformed rectangular closed cross section, and is held so as to cover the outer surface of the carrier 400 (in this embodiment, the upper surface and the left and right side surfaces). . The depth of the carrier fixing member 300i (the length in the extending direction of the separator 200) is appropriately set from the viewpoint of favorably holding the carrier 400, securing the exposed portion of the surface of the carrier 400, and the like. In the present embodiment, the depth is constituted by 4% of the diameter of the inner periphery of the pipe 910.
Note that the carrier fixing member 300i may have the same depth throughout.

  The shape of the carrier fixing member 300i is not limited to that shown in FIG. 15, and may be any shape as long as it is interposed between the concave curved surface 211 of the separator 200 and the carrier 400 and holds the carrier 400. As a result, the carrier 400 is fixed to the concave curved surface 211 of the separator 200 via the carrier fixing member 300i. The surface of the carrier fixing member 300 i that faces the concave curved surface 211 may be composed only of a curved surface that follows the concave curved surface 211. Alternatively, the carrier fixing member 300i and the concave curved surface 211 may be formed with a locking portion in which both are locked with each other.

  In the axial direction of the pipe line 910, the location and interval at which the carrier fixing member 300i is provided are not particularly limited. For example, with respect to one pipe line 910, you may provide in two places of the axial direction both ends, three places of the said both ends and center part, or more places.

  The carrier fixing member 300i can be made of resin. Examples of the resin include thermoplastic resins such as vinyl chloride resins and olefin resins, and thermosetting resins such as epoxy resins and unsaturated polyester resins. The resin may be in the form of a composite material, that is, FRP (fiber reinforced plastic) reinforced with a fiber material such as glass fiber or carbon fiber. The carrier fixing member 300i may be made of the same material as the separator 200 or may be different. The carrier fixing member 300i can be manufactured by injection molding. In the case of FRP, it can be produced by a hand lay-up method, a resin transfer molding method (RTM) method or the like.

  The carrier fixing member 300 i may be interposed between the concave curved surface 211 of the separator 200 and an adhesive. The adhesive can be appropriately determined by those skilled in the art in consideration of the material of the support portion 210 and the material of the carrier fixing member 300i. For example, a rubber adhesive mainly composed of styrene-butadiene, a solvent-based adhesive, and the like can be given.

The carrier fixing member 300j is a resin screw. The separator 200j is the same as the separator 200 of the first embodiment except that it has a screw hole. The screw holes of the separator 200j are formed so that the screw threads of the carrier fixing member 300j can be screwed together. Furthermore, screw holes are also formed in the carrier 400j.

  With such a configuration, the carrier 400j is fixed in the separator 200j by the carrier fixing member 300j. In this modification, since the carrier fixing member 300j is mechanically fixed to the separator 200j, an adhesive is not necessarily required. However, for stable fixation, an adhesive is interposed between the surface of the carrier 400j and the concave curved surface 211j of the support portion 210j and / or between the carrier fixing member 300j and the screw hole wall of the support portion 210j. Is preferred.

The support portion 210k is a flat plate-like member and contacts the lower inner wall of the pipe 910.
The partition part 250k is a deformed plate-like perforated member in which water-permeable holes 254k are formed. The partition portion 250k is configured in a shape in which the central portion (that is, the portion on the target axis) is lower than the left and right side portions. In this modification, the partition part 250k has a flow velocity securing part 251k at the lowest position on the symmetry axis, and a pair of inclined parts 255k is formed from the side closer to the symmetry axis toward the far side. The pair of inclined portions 255k are respectively arranged in parallel with the extending direction of the separator 200k.

The partition portion 250k may have a flat plate shape shown in FIG. 17, or may have a curved plate shape that protrudes downward.
As shown in FIG. 17, a water-permeable hole 254 k is formed in the inclined portion 255 k. In addition, as shown in FIG. 17, the inclined portion 255k is formed so as to rise from the flow velocity securing portion 251k toward the inner wall of the conduit 910 and gradually rise along the inner wall surface. The inclined portion 255k may have a flat plate shape as shown in FIG. 17, or an inclined curve that continues smoothly from the flow velocity securing portion 251k so as to protrude downward from the flat surface of the inclined portion 255k shown in FIG. It may be plate-shaped.

  In the separator 200k (the space constituting the purification unit 911), the carrier 400k may be filled without being fixed to the separator. In this case, the carrier 400k may be a number of small pieces, for example, cube-shaped pieces.

In the first to ninth embodiments and the first to third modifications, the separators 200, 200h, 200j, and 200k include the support portions 210, 210j, and 210k and the partition portions 250, 250h, Although 250 k has been integrally formed, the separator may be configured by combining separate and independent members.
Hereinafter, a fourth modification example in which the configuration of the separator is different will be described. Each of the first to ninth embodiments and the first to third modifications can be combined with the fourth modification.

[Fourth Modification]
FIG. 18 is a schematic cross-sectional view of the in-pipe purification apparatus of the fourth modified example, and corresponds to FIG. 3 of the first embodiment. An in-pipe purification apparatus 100l shown in FIG. 18 includes a separator 200l, a carrier 400 and a separator fixing member 500 similar to those in the first embodiment.
The separator 200l includes a support member 210l and a partition member 250l. The support member 210l and the partition member 250l are joined at both sides. As shown in FIG. 18, the cross-sectional shape of the separator 200l is axisymmetric with respect to a straight line passing through the axis O of the pipe 910 and the lowest point of the pipe 910 as an axis. And the separator 200l is comprised so that it may have a closed cross section except the part which has the water-permeable hole 254. FIG. That is, the lowermost part of the pipe line 910 is not opened.

  As shown in FIG. 18, the support member 210l is a curved plate member having fitting portions 217l on both sides. The fitting portions 217l are arranged in parallel with the extending direction of the separator 200l on both side portions of the support member 210l. The fitting portion 217l is formed in a male shape protruding from the concave curved surface 211l, and is fitted to a fitting portion 257l of a partition member 250l described later.

  The partition member 250l has a flow velocity securing portion 251 similar to that of the first embodiment (see FIG. 3) on the axis of symmetry, and a pair of the same as those of the first embodiment from the side closer to the axis of symmetry to the far side. A flat surface portion 253, a pair of inclined portions 255, and a pair of fitting portions 257l are formed in this order. The pair of flat portions 253, the pair of inclined portions 255, and the pair of fitting portions 257l are arranged in parallel in the extending direction of the separator 200, respectively. The flat portion 253 is provided with a water permeable hole 254 similar to that of the first embodiment. The fitting portions 257l formed on both sides are formed in a female shape and are fitted with the fitting portions 217l of the support member 210l.

  In the present modification, the fitting portion 217l and the fitting portion 257l are structurally configured to be detachable, so that no adhesive is required between the support member 210l and the partition member 250l. Further, it is not specifically excluded to intervene with an adhesive.

[Effects produced by embodiments and modifications]
The in-pipe purification devices 100, 100f,..., 100l are separators 200, 200h, 200j, 200k, 200l in which separator fixing members 500, 500f, 500g, 500h are to be disposed on the lower inner wall surface of the pipe 910. And the upper inner wall surface of the pipe line 910, the inner wall can be stably fixed to a normal pipe line 910 in which neither a concave portion nor a convex portion is formed.

  In the in-pipe purification devices 100, 100f, 100h,..., 100l, the pipe contact portions 520L, 520R, 520f of the separator fixing members 500, 500f, 500h have curved surfaces along the upper inner wall surface of the pipe 910. For this reason, the ground contact area between the pipe contact portions 520L, 520R, and 520f and the upper inner wall surface of the pipe 910 can be increased. For this reason, the in-pipe purification apparatuses 100, 100f, 100h, to 100l can be more stably fixed to the pipe 910.

  In the in-pipe purification apparatuses 100a to 100e, separator fixing portions 500a to 500e are interposed between the upper inner wall surface of the pipe 910 at the connecting portion of the separator 200. For this reason, the in-pipe purification apparatuses 100a to 100e can be stably fixed to a normal pipe 910 in which neither a concave portion nor a convex portion is formed on the inner wall.

  In the in-pipe purification apparatuses 100a to 100d, since the joint portion 550a and the separator fixing parts 500a to 500d are integrally formed, the fixing operation of the in-pipe purification apparatuses 100a to 100d becomes efficient. .

  In the pipe purification devices 100a to 100e, the pipe contact portions 520aL, 520aR, 520b, 520cL, 520cR, 520dL, and 520dR have curved surfaces along the upper inner wall surface of the pipe 910. The ground contact area with the upper inner wall surface of the can be increased. For this reason, the in-pipe purification apparatuses 100a to 100e can be more stably fixed to the pipe 910.
