<Embodiment>
1 to 3 are schematic views showing an example of the in-pipe purification apparatus 100 according to the present embodiment. FIG. 1 shows an example of the in-pipe purification device 100, and FIGS. 2 and 3 show the state of the in-pipe purification system 500 in which the in-pipe purification device 100 is disposed in the pipe 200. FIG.

  As shown in FIG. 1, the in-pipe purification apparatus 100 mainly includes microbial carriers 310 and 320 and a curved member 400.

  The curved surface member 400 is a curved surface along the inner peripheral surface of a pipe 200 (see FIG. 2) described later. Microbial carriers 310 and 320 are provided at the end of the curved member 400.

  Further, the curved member 400 has an outer peripheral diameter slightly larger than the inner peripheral diameter of the pipe 200 and is made of an elastic body. As a result, the microorganism carriers 310 and 320 can be brought closer due to the elasticity of the curved member 400. In this case, the outer peripheral diameter of the curved member 400 is smaller than the inner peripheral diameter of the pipe 200, and the in-pipe purification device 100 can be disposed on the inner periphery of the pipe 200.

Moreover, as shown in FIGS. 1 and 2, the microorganism carriers 310 and 320 are provided to face each other with the lowermost part P interposed therebetween. Further, the curved member 400 is formed in a circumference including the uppermost portion U without including the lowermost portion P so as not to exist in the vicinity of the lowermost portion P.
Here, the lowermost part P indicates a point positioned at the lowermost part of the pipe 200, and the uppermost part U indicates a point positioned at the uppermost part of the pipe 200.

  Examples of the material constituting the curved member 400 include resins such as polyethylene and vinyl chloride, fiber reinforced plastics, metals such as steel and ductile cast iron, reinforced concrete, and the like.

In the in-pipe purification apparatus 100 according to the present embodiment, the microbial carriers 310 and 320 are provided to face each other at a distance L1.
In addition, the microbial carriers 310 and 320 in the present embodiment have a thickness of t1 and a width of L3. In the present embodiment, the thickness (t1) is formed within a range of 5 mm or more and 50 mm or less, and the total width (L3) of the microorganism carrier is a range of 30% or more and 95% or less of the inner circumference of the pipe. Formed in.

The microbial carriers 310 and 320 have a problem that the microorganisms cannot be held at a high density when the thickness t1 is less than 5 mm, and the reactivity is lowered. When the thickness t1 exceeds 50 mm, the resistance becomes high and the flow rate is lowered. In addition, the microbial carriers 310 and 320 have a problem that the reactivity decreases when the total width is less than 30%, and there is a problem that when the width exceeds 95%, the resistance increases and the flow rate decreases.
Therefore, it is preferable that it is said size.

  The microbial carriers 310 and 320 are made of a granular or small piece material used for attaching aerobic microorganisms or the like. Specifically, the material constituting the microbial carriers 310 and 320 is made of a resin such as polyethylene, polypropylene, or polyurethane, or ceramics.

In addition, since the microbial carriers 310 and 320 require water permeability, when the microbial carriers 310 and 320 are made of a hydrophobic material such as polyethylene or polypropylene, it is preferable that the microbial carriers 310 and 320 have been subjected to a hydrophilic treatment.
In addition, since the microbial carriers 310 and 320 are required to efficiently contact oxygen and microorganisms (aerobic microorganisms), they have a large surface area and are not easily clogged with fibrous bodies, foams, porous bodies, or It is preferable to use a net or the like.

  In addition, when the microbial carriers 310 and 320 are made of a foam, it is preferable to use an open-cell type foam rather than a closed-cell type foam because the sewage is preferable to penetrate into the microbial carriers 310 and 320. Is preferred. A closed cell type may be used.

The shapes of the microorganism carriers 310 and 320 may be, for example, spherical, rectangular parallelepiped, cubic, sheet, fiber, or net. In this embodiment, the microbial carriers 310 and 320 will be described as a rectangular parallelepiped shape.
Moreover, in order to prevent the microbial carriers 310 and 320 from flowing out, the microbial carriers 310 and 320 may be sealed in a container having higher water permeability, such as a net or a perforated tube.

When the microbial carriers 310 and 320 are made of a fibrous body, a foamed body, a porous body, a net-like body, or the like, one having a high porosity is preferable in order to increase the surface area of the microbial carriers 310 and 320. Specifically, the porosity is preferably more than 50%, more preferably more than 80%.
In addition, said porosity means what represented the ratio of the clearance gap per unit volume by 100 fraction.

Moreover, as shown in FIGS. 1 and 2, the distance (L1) between the microbial carriers 310 and 320 is within a range of 10% to 40% of the diameter R2 of the in-pipe purification system 500. It is.
Further, as shown in FIG. 3, the in-pipe purification device 100 is formed to extend along the extending direction of the pipe 200.
In the present embodiment, the curved member 400 is formed to extend along the extending direction of the pipe 200. However, the present invention is not limited to this, and the curved member 400 is spaced at a constant distance. It may be formed.

The pipe 200 shown in FIGS. 2 and 3 is not particularly limited as long as it is a material that can be used as a sewage pipe, resin such as polyethylene and polyvinyl chloride, fiber reinforced plastic, steel, metal such as ductile cast iron, and reinforced concrete. It may consist of etc. The cross-sectional shape of the pipe 200 may be a pipe having a closed cross-sectional shape such as a circular shape or an oval shape, but is preferably a circular shape.
In addition, when it is not circular, the curved-surface-shaped member 400 is formed along each inner periphery.

  Next, FIGS. 4 and 5 are schematic cross-sectional views for explaining a case where sewage flows through the in-pipe purification system 500.

  As shown in FIG. 4, when sewage WL with a small amount of water flows through the in-pipe purification system 500, the microorganism carriers 310 and 320 are exposed to air. Moreover, the sewage WL flows downstream without being disturbed by the flow velocity.

  On the other hand, as shown in FIG. 5, when sewage WH with a large amount of water flows, the microorganism carriers 310 and 320 can act on purification by being immersed in the sewage WH.

As described above, the microbial carriers 310 and 320 repeat the immersion with sewage and the exposure with air according to the water level in the pipeline.
As a result, microorganisms (aerobic microorganisms) can naturally adhere to and grow on the microorganism carriers 310 and 320, and a purification action can be exerted.

<Other examples>
6 to 9 are schematic views showing other examples of the in-pipe purification system 500 and the in-pipe purification device 100 shown in FIGS.
FIG. 6 is a schematic diagram illustrating another example of the in-pipe purification apparatus 100, and FIG. 7 is a schematic diagram illustrating another example of the in-pipe purification system 500.
FIG. 8 is a schematic diagram showing another example of the in-pipe purification device 100, and FIG. 9 is a schematic diagram showing another example of the in-pipe purification system 500.

  Hereinafter, differences between the in-pipe purification devices 100a and 100b and the in-pipe purification systems 500a and 500b from the in-pipe purification device 100 and the in-pipe purification system 500 will be described. In addition, description is abbreviate | omitted about the same part. In the following other examples, the description of the same part will not be repeated.

  As shown in FIGS. 6 and 7, the in-pipe purification device 100 a is different from the in-pipe purification device 100 in that a microbial carrier 330 a is formed instead of the microbial carriers 310 and 320. The microorganism carrier 330a is provided on the entire inner peripheral side of the curved member 400a.

  In the present embodiment, the microorganism carrier 330a is provided on the entire inner peripheral side of the curved member 400a. However, the present invention is not limited thereto, and may be provided on the entire periphery of the curved member 400a.

  Moreover, if the microorganism carrier 330a in FIG. 6 and FIG. 7 is disposed so as not to be disposed at the lowermost part in the pipe 200, the problem that the resistance increases and the flow rate decreases is less likely to occur.

  Further, as shown in FIGS. 8 and 9, the in-pipe purification device 100b is provided with a curved member 400b instead of the curved member 400a of the in-pipe purification device 100a. The curved surface member 400b is formed shorter than the curved surface member 400a, and the microbial carrier 330b having a thickness larger than that of the microbial carrier 330a is formed at the end of the curved surface member 400b formed shorter than the curved surface member 400a.

  In FIG. 8 and FIG. 9, the curved member 400b is not formed in a portion that is highly likely to be immersed in sewage, but a microbial carrier 330b is formed instead.

  As a result, immersion with sewage and exposure with air are repeated, and microorganisms (aerobic microorganisms) naturally adhere to and grow on the microorganism carriers 330a and 330b, thereby enabling a purification action.

The microorganism carriers 310c and 320c are provided to face each other with the lowermost part P interposed therebetween.
Here, the lowest part P shows the point located in the lowest part of the piping 200. FIG.

Next, as shown in FIG. 11, in the in-pipe purification system 500c, the in-pipe purification device 100c is fixed to the lowermost portion P of the pipe 200 by the fixing portion 450c. The fixing portion 450 c is for fixing the in-pipe purification device 100 c to the pipe 200.

  The microbial carriers 310c and 320c have a problem that the microorganisms cannot be held at a high density when the thickness t1 is less than 5 mm, and the reactivity is lowered. When the thickness is more than 50 mm, the resistance becomes high and the flow rate is lowered. In addition, the microbial carriers 310c and 320c have a problem that the reactivity decreases when the width is less than 30% of the inner circumference of the pipeline, and the resistance is high when the width exceeds 95% of the inner circumference of the pipeline.

  Further, the curved member 400 has an outer peripheral diameter slightly larger than the inner peripheral diameter of the pipe 200 and is made of an elastic body. As a result, the microorganism carriers 310 and 320 can be brought closer due to the elasticity of the curved member 400. In this case, the outer peripheral diameter of the curved member 400 is smaller than the inner peripheral diameter of the pipe 200, and the in-pipe purification device 100 can be disposed on the inner periphery of the pipe 200.

Moreover, as shown in FIGS. 1 and 2, the microorganism carriers 310 and 320 are provided to face each other with the lowermost part P interposed therebetween. Further, the curved member 400 is formed in a circumference including the uppermost portion U without including the lowermost portion P so as not to exist in the vicinity of the lowermost portion P.
Here, the lowermost part P indicates a point positioned at the lowermost part of the pipe 200, and the uppermost part U indicates a point positioned at the uppermost part of the pipe 200.

  Examples of the material constituting the curved member 400 include resins such as polyethylene and vinyl chloride, fiber reinforced plastics, metals such as steel and ductile cast iron, reinforced concrete, and the like.

In the in-pipe purification apparatus 100 according to the present embodiment, the microbial carriers 310 and 320 are provided to face each other at a distance L1.
In addition, the microbial carriers 310 and 320 in the present embodiment have a thickness of t1 and a width of L3. In the present embodiment, the thickness (t1) is formed within a range of 5 mm or more and 50 mm or less, and the total width (L3) of the microorganism carrier is a range of 30% or more and 95% or less of the inner circumference of the pipe. Formed in.

The microbial carriers 310 and 320 have a problem that the microorganisms cannot be held at a high density when the thickness t1 is less than 5 mm, and the reactivity is lowered. When the thickness t1 exceeds 50 mm, the resistance becomes high and the flow rate is lowered. In addition, the microbial carriers 310 and 320 have a problem that the reactivity decreases when the total width is less than 30%, and there is a problem that when the total width exceeds 95%, the resistance increases and the flow rate decreases. .
Therefore, it is preferable that it is said size.

  The microbial carriers 310 and 320 are made of a granular or small piece material used for attaching aerobic microorganisms or the like. Specifically, the material constituting the microbial carriers 310 and 320 is made of a resin such as polyethylene, polypropylene, or polyurethane, or ceramics.

In addition, since the microbial carriers 310 and 320 require water permeability, when the microbial carriers 310 and 320 are made of a hydrophobic material such as polyethylene or polypropylene, it is preferable that the microbial carriers 310 and 320 have been subjected to a hydrophilic treatment.
In addition, since the microbial carriers 310 and 320 are required to efficiently contact oxygen and microorganisms (aerobic microorganisms), they have a large surface area and are not easily clogged with fibrous bodies, foams, porous bodies, or It is preferable to use a net or the like.

  In addition, when the microbial carriers 310 and 320 are made of a foam, it is preferable to use an open-cell type foam rather than a closed-cell type foam because the sewage is preferable to penetrate into the microbial carriers 310 and 320. Is preferred. A closed cell type may be used.

The shapes of the microorganism carriers 310 and 320 may be, for example, spherical, rectangular parallelepiped, cubic, sheet, fiber, or net. In this embodiment, the microbial carriers 310 and 320 will be described as a rectangular parallelepiped shape.
Moreover, in order to prevent the microbial carriers 310 and 320 from flowing out, the microbial carriers 310 and 320 may be sealed in a container having higher water permeability, such as a net or a perforated tube.

When the microbial carriers 310 and 320 are made of a fibrous body, a foamed body, a porous body, a net-like body, or the like, one having a high porosity is preferable in order to increase the surface area of the microbial carriers 310 and 320. Specifically, the porosity is preferably more than 50%, more preferably more than 80%.
In addition, said porosity means what represented the ratio of the clearance gap per unit volume by 100 fraction.

Moreover, as shown in FIGS. 1 and 2, the distance (L1) between the microbial carriers 310 and 320 is within a range of 10% to 40% of the diameter R2 of the in-pipe purification system 500. It is.
Further, as shown in FIG. 3, the in-pipe purification device 100 is formed to extend along the extending direction of the pipe 200.
In the present embodiment, the curved member 400 is formed to extend along the extending direction of the pipe 200. However, the present invention is not limited to this, and the curved member 400 is spaced at a constant distance. It may be formed.

The pipe 200 shown in FIGS. 2 and 3 is not particularly limited as long as it is a material that can be used as a sewage pipe, resin such as polyethylene and polyvinyl chloride, fiber reinforced plastic, steel, metal such as ductile cast iron, and reinforced concrete. It may consist of etc. The cross-sectional shape of the pipe 200 may be a pipe having a closed cross-sectional shape such as a circular shape or an oval shape, but is preferably a circular shape.
In addition, when it is not circular, the curved-surface-shaped member 400 is formed along each inner periphery.

  Next, FIGS. 4 and 5 are schematic cross-sectional views for explaining a case where sewage flows through the in-pipe purification system 500.

  As shown in FIG. 4, when sewage WL with a small amount of water flows through the in-pipe purification system 500, the microorganism carriers 310 and 320 are exposed to air. Moreover, the sewage WL flows downstream without being disturbed by the flow velocity.

  On the other hand, as shown in FIG. 5, when sewage WH with a large amount of water flows, the microorganism carriers 310 and 320 can act on purification by being immersed in the sewage WH.

As described above, the microbial carriers 310 and 320 repeat the immersion with sewage and the exposure with air according to the water level in the pipeline.
As a result, microorganisms (aerobic microorganisms) can naturally adhere to and grow on the microorganism carriers 310 and 320, and a purification action can be exerted.
