JP5313829B2 - Cover assembly for sewer facilities and method of use - Google Patents

Description

  The present invention relates to a cover lid assembly used for covering an upper portion of a sewerage facility and a method for using the same.

  In sewerage facilities such as the first sedimentation basin, reaction tank, and final sedimentation basin, the upper part is covered with a cover for the purpose of preventing the spread of malodor. The cover covers are usually placed in the width direction in a state of being adjacent to each other and are spanned over the casings forming the sewerage facility, and the deodorizing duct is connected to the dozens of cover covers at a rate of about one place. Has been. The deodorization duct is for guiding the odor gas generated from the sewage (in-house sewage, raw water) accommodated in the sewer facility to the outside of the cover and sending it to the deodorizer installed around the sewer facility.

  In recent years, paying attention to the fact that such a sewerage facility is provided in a large area in a place with good solar radiation conditions, a solar cell module such as a solar cell panel is installed on the upper surface of the cover to perform solar power generation. Attempts have been made (see Patent Document 1).

  However, the conventional sewerage facilities or the cover used there have the following problems.

  (A) The conventional deodorization duct protrudes upward from the center of the cover, further extends in a horizontal direction from a predetermined height (around 3 to 5 m above the cover), passes over the other cover, and deodorizes. Since it is arranged so as to face the device, a part of the solar cell module installed on the upper surface of the cover is shaded by the deodorizing duct. Normally, the solar cell modules installed on the upper surface of the cover are connected in series, so when some of them are in the shade, the cells in the shaded part do not generate electricity, and only the cells in the other part generate electricity and generate current. Since the cells flow, the shaded cells generate resistance and generate heat, leading to a decrease in power generation efficiency.

  (B) In order to dispose the deodorizing duct so as to pass above the cover as described above, it is necessary to construct a large number of supports (supports) for supporting the deodorizing duct, which increases the construction cost. In addition, when the deodorizing duct is arranged above the cover, the processing place becomes cluttered and the landscape becomes worse.

  (C) Since the deodorizing duct is connected to several dozen adjacent cover covers at a rate of about one as described above, odor is sucked into the deodorization duct in the vicinity of the cover cover to which the deodorizing duct is connected. However, as the distance from the cover to which the deodorizing duct is connected increases, it becomes difficult for odors to be sucked into the deodorizing duct, so uniform deodorization cannot be performed at all positions, and the degree of deodorization varies depending on the position. .

  (D) Conventionally, the cover and the duct are individual structures, and it has been necessary to manufacture and install them for each. Therefore, the manufacturing cost is high, and the construction period of the installation work becomes long.

  (E) Patent Document 2 discloses a device that can be deodorized by a deodorizing function provided to the cover itself without disposing a deodorization duct from the cover to the external deodorization device (deodorization tower). In this cover, most of the electric power generated in the solar cell module is consumed by the exhaust fan attached to the cover, so that the power can hardly be used for other purposes.

  This invention is made | formed in view of such a conventional situation, The subject is solving the said (A)-(E) problem. Specifically, the power generation efficiency of the solar cell module when installed on the top surface is high, and the generated power can be used for applications other than fans, which can reduce construction costs and shorten the construction period. It is an object of the present invention to provide a cover means for a sewerage facility that is possible, has a good landscape of the sewerage facility, and can be appropriately deodorized.

  In order to solve this problem, according to the present invention, a cover assembly of a sewerage facility and a method of using the cover assembly are provided as follows.

  That is, first, according to the present invention, it is a cover assembly composed of a plurality of cover covers for covering the upper part of the sewerage facility, and is inclined at a predetermined angle in the length direction of the cover cover, and the solar cell module is installed on the surface. A cover lid (A) having an upper surface plate formed thereon, a rear plate extending downward from the upper end of the upper surface plate, and one side surface plate connecting between the rear plate and one side end of the upper surface plate, And a top plate that is inclined at a predetermined angle in the length direction of the cover and on which the solar cell module is installed, a back plate that extends downward from the upper end of the top plate, and the other of the back plate and the top plate And a cover (B) having a side plate connecting between the side edges of the cover, and the cover (A) and the cover (B) are arranged adjacent to each other, and the top plate of the cover (A) The upper surface plate of the cover (B) forms a flat surface, and the cover (A) Provided is a cover cover assembly of a sewerage facility surrounded by an upper surface plate, a rear surface plate, and a side surface plate, and an upper surface plate, a rear surface plate, and a side surface plate of a cover (B), and having an internal space opened downward. Is done.

  In the cover assembly of the sewerage facility according to the present invention (also simply referred to as a cover assembly), an upper surface plate that is inclined at a predetermined angle in the length direction of the cover and on which the solar cell module is installed, One or more cover (C) having a back plate extending downward from the upper end of the upper surface plate, and disposed adjacent to the cover (C) between the cover (A) and the cover (B), The top plate of the cover (A), the top plate of the cover (B), and the top plate of the cover (C) form one plane, and the top plate, back plate, and side plate of the cover (A) It is preferable that an internal space is formed that is surrounded by the top plate and the back plate of the cover (C) and the top plate, the back plate, and the side plate of the cover (B) and that opens downward.

  A sewer facility is a facility having a tank (water tank) or a pond that performs various treatment of sewage, storing water, such as a first sedimentation basin, an aeration tank, a reaction tank, and a final sedimentation basin. The cover cover assembly is a cover cover assembly for covering the upper part of these cover cover assemblies.

  The cover assembly of the sewerage facility according to the present invention includes a plurality of cover covers, and preferably includes a cover cover (C) in addition to the cover cover (A) and the cover cover (B). The cover (A) has a side plate connecting between one side end of the back plate and the top plate, and between the other side end (on the opposite side to the above) of the back plate and the top plate. There is no side plate to connect. The cover (B) has a side plate that connects between the other side of the back plate and the top plate (on the side opposite to the one in the cover (A)), and one of the back plate and the top plate ( There is no side plate connecting between the end portions on the side opposite to the other side. The cover (C) is disposed between the cover (A) and the cover (B), and has no side plate at all. That is, in the cover assembly of the sewerage facility according to the present invention, there are two side plates as a whole. The cover assembly of the sewerage facility according to the present invention covers the upper part of the sewerage facility by combining these cover (A), cover (B), and cover (C), and can also be referred to as a separable cover.

  In the cover assembly of the sewerage facility according to the present invention, the plurality of cover covers are arranged adjacent to each other, and as a result, a single flat surface is formed by each upper surface plate. Accordingly, the plurality of cover lids are arranged without a gap so that the side end portions of the top plate (and the side end portions of the back plate) are in contact with each other. In order to arrange in such a manner, it is preferable that the plurality of cover covers have a certain relationship at the side end portions of the top plate and the back plate. For example, they may be joined, fitted, engaged, engaged, and twisted to each other, but it is desirable that the plurality of cover covers have the following relationship in consideration of construction.

  That is, in the cover assembly of the sewerage facility according to the present invention, the plurality of cover covers that are arranged adjacent to each other overlap at the side edges of the top plate and the back plate that are in contact with each other. It is preferable to have a rib.

  The cover assembly of a sewerage facility according to the present invention can be used to replace an existing cover in a sewerage facility with a cover provided with a solar cell module that efficiently generates power. In this case, the width of each cover constituting the cover assembly (the dimensions of the cover in the direction in which the covers are adjacent to each other) can correspond to the existing cover. However, since the plurality of cover covers are arranged adjacent to each other (without a gap), the width is slightly wider than the existing cover cover. Moreover, the width | variety of each cover can be match | combined with the standard dimension of the solar cell module to be used. This is more preferable than making the other size correspond to the existing cover. This is because the solar cell modules installed on the individual cover can be arranged adjacent to each other. In the cover assembly of the sewerage facility according to the present invention, the plurality of cover covers are formed by forming a single plane (with the respective upper surface plates). Therefore, the sewerage system is installed without installing the solar cell module. It is possible to cover the upper part of the facility and later install the solar cell module on the upper surface plate that forms one plane, but such means arranges the cover lid on which the solar cell module is installed adjacently. Compared to cases, workability and safety are inferior.

  In the cover assembly of the sewerage facility according to the present invention, the odor gas generated from the sewage contained in the sewerage facility is guided to at least one of the side plate of the cover (A) and the side plate of the cover (B). It is preferable that a deodorizing duct leading to the internal space is provided. Alternatively, in the cover assembly of the sewerage facility according to the present invention, a carrier in which microorganisms that decompose malodors are fixed is disposed in the internal space, and a pipe for sprinkling the carrier has a top plate. It is preferable to be provided through the back surface of the solar cell module.

Is preferred. Moreover, it is preferable that an opening area adjusting means for adjusting the opening area of the opening that leads to the internal space is provided on the side surface of the deodorizing duct.

  In the cover assembly of the sewerage facility according to the present invention, it is preferable that an opening / closing inspection port for checking the inside (of the cover assembly) is provided on the back plate.

  The back plate (upper plate, side plate) of the cover assembly means a back plate (upper plate, side plate) of the cover that forms the cover assembly. Since the cover cover assembly is composed of a plurality of cover covers, there are a plurality of back plates (upper surface plate, side plate) of the cover cover assembly. In this specification, the back plate (upper surface plate, side plate) of the cover assembly means any one or more back plates (upper surface plate, side plate).

  In the cover assembly of the sewerage facility according to the present invention, it is preferable that the upper surface plate is also provided with an openable / closable inspection port for inspecting the inside (of the cover assembly).

  In the cover lid assembly of the sewerage facility according to the present invention, the inclination angle of the upper surface plate is preferably greater than 0 ° and not greater than 30 °. The inclination angle of the upper surface plate is more preferably 10 to 30 °, and particularly preferably 30 °.

The angle formed by the outer surface of the back plate and the horizontal surface is more preferably 120 to 135 °.

  In the cover assembly of the sewerage facility according to the present invention, it is preferable that the internal space is provided with a wiring storage chamber for storing the wiring of the solar cell module, which is partitioned from other portions of the internal space. In this case, it is preferable that the back plate is provided with an openable / closable inspection port that leads from the outside (of the cover lid assembly) to the wiring housing chamber.

  In the cover lid assembly of the sewerage facility according to the present invention, LED lighting is preferably provided in the internal space.

  In the cover assembly of the sewerage facility according to the present invention, it is preferable that a water sprinkling port for spraying the on-site treated water of the sewerage facility is provided above the upper surface plate.

  In the cover lid assembly of the sewerage facility according to the present invention, it is preferable that the upper portion of the upper surface plate is constituted by a horizontal plane. In this specification, the part comprised by a horizontal surface among upper surface boards is called a horizontal surface part, and the part inclined by the said preferable inclination angle is called an inclined surface part.

  In the cover lid assembly of the sewerage facility according to the present invention, it is preferable that one or more of the top plate, the back plate, and the side plate have an arch shape.

  In the cover lid assembly of the sewerage facility according to the present invention, the solar cell module is preferably an amorphous solar cell module. That is, the solar cell is preferably an amorphous solar cell.

  Next, according to the present invention, there is provided a cover double assembly of a sewerage facility in which the deodorization ducts of the cover cover assembly provided with the above-described deodorization duct are connected to each other. The cover-cover complex is a combination of a plurality of cover-deodorizing ducts.

  Next, according to the present invention, the cover assembly of any of the above-described sewer facilities is disposed and used such that the lower side of the slope of the upper surface plate (of the cover) is oriented from southeast to south to southwest. A method of using the facility cover assembly is provided.

  The cover assembly of the sewerage facility according to the present invention is composed of a plurality of cover covers, and the cover covers (A), the cover cover (B), and (preferably) the cover cover (C) are arranged adjacent to each other. Since the upper surface plate forms a single plane, the area of the sewerage facility can be used effectively and the area where the solar cell module can be installed can be increased. Therefore, the power generation efficiency is high by area ratio. Since the deodorizing duct is not provided between the cover (A), the cover (B), and the cover (C) in the cover assembly of the sewerage facility according to the present invention, the solar cell modules can be installed at high density. Therefore, the cover assembly of the sewerage facility according to the present invention can be called a (solar cell module) high-density arrangement type cover (assembly).

  The cover assembly of the sewerage facility according to the present invention can be said to be a combination of a plurality of cover covers to form one cover (collection), and since one cover is lightweight and easy to install (construct), Shorten construction costs (especially personnel costs).

  Since the cover assembly of the sewerage facility according to the present invention is to install the solar cell module on the surface (of the top plate), the portion covered with the solar cell module does not need to be repainted, The painted area is reduced. If each cover is made of glass fiber reinforced resin (FRP), repair work such as repainting is required at a rate of about once every 10 or more years, but the cover cover assembly of the sewerage facility according to the present invention is used. This burden will be reduced.

  In a preferred embodiment of the cover cover assembly of the sewerage facility according to the present invention, the plurality of cover covers arranged adjacent to each other overlap at the side end portions of the upper surface plate and the back plate that are in contact with each other, and the overlapping overlapping portions. Moreover, since it has a rib, it is easy to construct and is robust (after construction).

  In a preferred embodiment of the cover assembly of a sewerage facility according to the present invention, a deodorizing duct for guiding odor gas to the outside is provided on at least one of the two side plates as a whole, or a bad odor is formed in the internal space. A carrier on which microorganisms for decomposing are fixed is disposed. In the former case, the deodorizing process is concentrated at another place as in the past, and in the latter case, the deodorizing process is performed in the cover lid assembly (dispersed as a whole), and is not necessary for the deodorizing duct. is there. That is, the latter can be referred to as a cover-cover assembly incorporating a biological deodorization device, and is a cover (assembly) that can be deodorized alone. In any case, unlike the conventional case, the solar cell module installed on the top plate cannot be shaded by the deodorizing duct, and high power generation efficiency can be obtained.

  Specifically, conventionally, the deodorization duct protrudes upward from the center of the cover, further extends in a horizontal direction from a predetermined height (near 3 to 5 m above the cover), passes through the cover, and deodorizes. A part of the solar cell module installed on the upper surface of the cover lid is shaded by the deodorizing duct, leading to a decrease in power generation efficiency in order to go to the device, but it is preferable for the cover assembly of the sewerage facility according to the present invention. According to the aspect, since the deodorizing duct is provided on the side plate or there is no deodorizing duct, the solar cell module cannot be shaded by the deodorizing duct, and the power generation efficiency is improved.

  In the preferable embodiment of the cover cover assembly of the sewerage facility according to the present invention, the deodorizing duct is provided on the side plate or the deodorizing duct is eliminated, so that the solar cell module is installed on the main surface (surface of the upper plate). Also in this respect, it is possible to effectively use the area of the sewerage facility and increase the area where the solar cell module can be installed. Therefore, the power generation efficiency is high by area ratio.

  In the preferable embodiment, the cover assembly of the sewerage facility according to the present invention is provided with a deodorizing duct on the side plate or eliminated the deodorizing duct, so that the deodorizing duct is placed in the vicinity of 3 to 5 m above the cover as in the conventional case. There is no need to make a support (support) for supporting the deodorizing duct in the sky, and even when there is a deodorizing duct, its length is shorter than before.

  When the cover assembly of the sewerage facility according to the present invention is provided with a deodorization duct, the cover (cover (A), cover (B)) and the deodorization duct can be integrated with each other. For example, an integral type can be formed. Conventionally, the cover and the deodorizing duct are individual structures, and it has been necessary to carry out manufacturing and installation work for each of them. As a result, the construction cost is reduced and the landscape of the treatment plant is improved.

  When the cover assembly of the sewerage facility according to the present invention is provided with a deodorization duct, since the deodorization duct communicates with the internal space, odor gas can be sucked from there and is covered with a plurality of cover covers. It is possible to deodorize evenly in all locations of the sewerage facilities. In addition, when a deodorizing duct is not provided and a carrier is disposed in the internal space so that the deodorizing process can be performed by the cover alone, uniform deodorization without unevenness can be performed within the cover assembly.

  When the cover assembly of the sewerage facility according to the present invention is provided with a deodorization duct, since the odor sampling port is provided in the deodorization duct, the maintenance management such as the measurement of the odor described above can be performed easily and safely. And

  When the cover assembly of the sewerage facility according to the present invention is provided with a deodorization duct, the deodorization duct is not above the cover, but is in a low position close to the passage of the side surface (plate) of the cover. By installing an odor sampling port for collecting odor gas in order to measure the odor of the odor gas generated from the sewage in the site and a valve for draining water to remove the water accumulated inside the deodorization duct, Maintenance such as odor measurement and deodorizing duct drainage can be carried out easily and safely without the operator going from the passage to the center of the cover or climbing to a high place.

  When the cover assembly of the sewerage facility according to the present invention is provided with a deodorizing duct, the side surface of the deodorizing duct is provided with an opening area adjusting means for adjusting the opening area of the opening leading to the internal space. In the case where a cover double assembly described later is configured, the odor gas can be sucked and equalized in each cover cover assembly.

  When the cover assembly of the sewerage facility according to the present invention enables deodorization treatment with the cover assembly alone, the treated water used for watering does not need to be returned to the settling basin at first, and the sewer facility covering the sewerage facility is covered. It only needs to be discharged into a reaction tank, etc., and piping work is unnecessary.

  In the cover assembly of the sewerage facility according to the present invention, when the deodorization treatment is enabled by the cover assembly alone, the piping for watering the carrier is the surface of the upper surface plate and passes through the back surface of the solar cell module. Therefore, the solar cell module can be cooled by the treated water used for watering the carrier (water that has been sewage treated and passes through the pipe), and a reduction in power generation efficiency can be suppressed.

  In the preferred embodiment, the cover assembly of the sewerage facility according to the present invention is provided with an openable / closable inspection port for inspecting the inside of the cover on the back plate, so that the operator can perform the internal inspection work in a comfortable posture. In addition to being able to do this, it is possible to prevent the worker himself or the worker from putting in his jacket pocket from falling into the water. In addition, since the operator does not look into the inspection port from above, the operator's glasses are not fogged by the steam rising from the inspection port when the door is opened. Further, since the angle of the line of sight becomes shallow with respect to the water surface during inspection, the range of the water surface that can be viewed from the inspection port is widened, and inspection over the entire water surface is facilitated. As will be described later, the upper surface of a conventional cover has a gentle arch shape or a horizontal flat surface, and an inspection port is provided on the upper surface. The body (upper body) bends into a hard posture that looks down and is burdened on the body, and the operator falls into the water from the inspection port or is in the jacket pocket (cell phone , Writing utensils, etc.) could be dropped and submerged in water. Further, the glasses of the worker may be clouded by the steam rising when the opening / closing door of the inspection port is opened. Furthermore, since the angle of the line of sight becomes almost perpendicular to the water surface at the time of inspection, there is a problem that the range of the water surface that can be viewed from the inspection port is narrow and it is difficult to inspect the entire water surface. According to this preferable aspect of the cover lid assembly of the sewerage facility according to the present invention, such a problem does not occur.

  In the preferable embodiment, the cover assembly of the sewerage facility according to the present invention is further provided with an openable / closable inspection port for inspecting the inside of the cover, so that the inspection can be performed efficiently.

  In the preferred embodiment of the cover cover assembly of the sewerage facility according to the present invention, the inclination angle of the upper surface plate is greater than 0 ° and 30 ° or less, so that rain and snow that have fallen on the solar cell module flow down naturally, Since it is difficult to stay on the solar cell module, it is possible to prevent the sunlight from being blocked by the snow on the solar cell module, thereby reducing the power generation efficiency and the cover 1 from being damaged by the weight of the snow. Furthermore, when the solar cell module is installed on the surface of the inclined upper plate, when the cover is installed in a predetermined direction, the incident angle of sunlight with respect to the solar cell module is increased, and the power generation efficiency is improved.

  In the preferable embodiment of the cover cover assembly of the sewerage facility according to the present invention, the angle formed by the outer surface of the back plate and the horizontal surface is 90 to 150 °. The above effect can be easily obtained.

  In a preferred embodiment of the cover lid assembly of the sewerage facility according to the present invention, the internal space is provided with a wiring storage chamber for storing the wiring of the solar cell module, which is partitioned from other portions of the internal space. Thus, if the wiring of the solar cell module is housed in the wiring housing chamber partitioned from the other part of the internal space, the wiring can be used even if the odor gas generated from the sewage in the field is a corrosive gas. Can be shielded from corrosive gas to prevent corrosion deterioration of the wiring.

  In the preferred embodiment of the cover cover assembly of the sewerage facility according to the present invention, the back plate is provided with an openable / closable inspection port that leads from the outside of the cover cover to the wiring storage chamber. Wiring connection work can be done easily.

  In the preferable embodiment, the cover cover assembly of the sewerage facility according to the present invention is provided with LED illumination in the internal space, so that the interior of the cover cover assembly is brightly illuminated, so that the visibility is improved and the work is performed at the time of inspection. No longer need to carry a flashlight. Conventionally, since the inside of a sewerage facility covered with a cover is dark, it was necessary to illuminate the interior with a flashlight or the like when inspecting the interior from the inspection port, but the cover assembly of the sewerage facility according to the present invention According to that, it is not necessary. As the power supplied to the LED lighting, the power generated by the solar cell module installed in the cover assembly can be used. Even in such a case, the LED lighting consumes little power and is turned off except during inspection. Therefore, unlike the exhaust fan in the above cited reference 2, it does not consume most of the electric power generated in the solar cell module, and other uses of electric power (other than maintaining the function of the cover) Effective use for (uses) is not greatly restricted.

  In the preferred embodiment, the cover assembly of the sewerage facility according to the present invention is provided with a water spout for spraying the treated water in the sewerage facility at the upper part of the upper surface plate, so that it is sucked up by a pump or the like at high temperatures in summer. If the in-situ treated water (water temperature is about 15 to 20 ° C. throughout the year) is sprayed from this sprinkling port, the solar cell module is cooled, and the temperature rise is suppressed, a decrease in power generation efficiency can be suppressed. In general, as the temperature rises, the power generation efficiency of the solar cell module decreases, but this can be prevented.

  In the preferred embodiment of the cover cover assembly of the sewerage facility according to the present invention, the upper part of the upper surface plate is constituted by a horizontal plane, so that the height can be suppressed. Therefore, when a cover double assembly described later is configured, it is difficult for the solar cell module installed on the upper surface plate to be shaded by another cover cover assembly, and high power generation efficiency is obtained.

  In the preferable embodiment, the cover lid assembly of the sewerage facility according to the present invention has an arch shape and any one or more of the top plate, the back plate, and the side plate has excellent strength. Even if a person gets on it, it is difficult to break, and can withstand the increase in pressure (internal pressure) from the sewerage facility side.

  In the preferable embodiment of the cover cover assembly of the sewerage facility according to the present invention, the solar cell module is an amorphous solar cell module. Is big. For example, even if the top plate has an arch shape, it can be mounted, which contributes to the weight reduction of the entire cover.

  The cover double assembly according to the present invention is formed by connecting the deodorizing ducts of the cover cover assembly of the sewerage facility according to the present invention, so that the cover assembly of the sewerage facility according to the present invention is expressed. Similarly, the (facility) as a whole can be enjoyed.

  In the method of using the cover assembly according to the present invention, the cover assembly of any of the above-described sewer facilities is arranged and used so that the lower side of the slope in the upper surface plate of the cover is in the direction from southeast to south to southwest. . If the cover with the solar cell module installed on the surface of the inclined upper surface plate is arranged in such a direction, the incident angle of sunlight with respect to the solar cell module is increased, and high power generation efficiency is obtained.

  In the cover cover assembly used in the above method of use, the inclination angle of the top plate is preferably greater than 0 ° and 30 ° or less, more preferably 10 to 30 °, and particularly preferably 30 °. If the inclination angle is in such a range, sunlight enters the solar cell module at an ideal incident angle, and higher power generation efficiency can be obtained.

It can be additionally provided in the part that is not. As shown in FIG. 6, when the plurality of sewer facilities 30 and 31 are arranged in parallel at relatively short intervals and the directions of the cover assembly 1 covering the upper side are all the same, the cover assembly 1 When the inspection port 11 is provided only on the back plate 3, the inspection port 11 is provided only on either the left or right side of the passage 32 between the sewer facilities 30, 31, so that the operator who performs the inspection is shown in FIG. The entire route needs to be inspected while moving a long distance on the movement route indicated by the arrow 33. On the other hand, as shown in FIG. 8, when the inspection port 13 is provided not only on the back plate 3 of the cover assembly 1 but also on the top plate 2, both left and right sides of the passage 32 between the sewer facilities 30, 31 are provided. Since there are inspection ports 11 and 13, the inside of the cover assembly 1 on both the left and right sides of the passage 32 can be inspected at substantially the same position, and the entire inspection work can be performed with a short movement distance by the movement route indicated by the arrow 34. Can be done. In addition, such an inspection port does not need to be provided in all the cover cover assemblies arranged adjacent to each other, and normally, the cover cover assembly provided with the check ports is provided at a ratio of about one to several tens. It only has to be arranged. That is, there may be a cover lid assembly in which no inspection port is provided.

  The side plate 4 is a member that connects between the side end portions of the top plate 2 and the back plate 3. In the cover assembly 1, the side plate 4 is generated from the in-situ sewage contained in the sewer facility on the side plate 4 of the cover 10 a.

In order to measure the odor of the generated odor gas, an odor sampling port 18 for collecting the odor gas, a valve for draining water for removing the water accumulated in the deodorization duct, and the like are provided in the deodorization duct 5 (FIG. 10). In the cover assembly 1, the deodorizing duct 5 can be a part of the cover assembly 1, and in that case, it can be integrally formed.

  In the cover assembly 1, as shown in FIG. 9, a solar cell module that is partitioned from the other part of the internal space 7 by the internal space 7 surrounded by the top plate 2, the back plate 3, and the side plate 4. A wiring accommodating chamber 17 for accommodating six wirings can be provided.

When the deodorizing ducts 5 of the plurality of cover assembly 1 are connected to form a cover multi-assembly, in order to equalize the inhalation of odor gas in each cover assembly, It is preferable that an opening area adjusting means for finely adjusting the opening area is provided. In the embodiment shown in FIG. 11, a slidable door 22 is provided as the opening area adjusting means, and the opening area of the opening 21 is adjusted by sliding the door 22 in the direction of the arrow. I can do it. The door 22 is integrally provided with an adjustment knob 23 protruding in the radial direction of the deodorizing duct 5 so that the adjustment can be easily performed. The opening area of the opening 21 can be adjusted by, for example, inserting a jig that can hold the adjustment knob 23 from the inspection port provided in the back plate 3 into the internal space 7 and holding the adjustment knob 23 with the jig. This can be done by sliding the door 22.

  FIG. 15 is a side view corresponding to FIG. In the cover lid assembly 101 shown in FIG. 15, (in each cover), the upper surface plate 2 has a horizontal surface portion 2 a on the upper portion, and the upper surface plate 2 is configured with a horizontal surface. The horizontal plane 2a is provided with a daylighting window 27 that brightens the internal space. A part of the divided solar cell module 6 is also disposed on the horizontal surface portion 2a. Structures other than these are common to the cover lid assembly 1.

  FIG. 16 is a side view corresponding to FIG. The cover assembly 102 shown in FIG. 16 is different in that the top plate 2 has an arch shape (in each cover). And the solar cell module 6 comprised by an amorphous solar cell is arrange | positioned along the shape on the arch-shaped upper surface board 2, for example. Structures other than these are common to the cover lid assembly 1.

  FIG. 17 is a cross-sectional view corresponding to FIG. In the cover assembly 110 shown in FIG. 17, similarly to the cover assembly 101, (in each cover), the upper surface plate 2 has a horizontal surface portion 2 a on the upper surface 2, and the upper surface plate 2 is configured with a horizontal surface. The horizontal plane 2a is provided with a daylighting window 27 that brightens the internal space, and a part of the divided solar cell module 6 is also disposed in the horizontal plane 2a. The internal space 7 is provided with a biological deodorization device, and the side plate 4 is not provided with the deodorization duct 5. Structures other than these are common to the cover lid assembly 1.

  In the cover assembly 110, a carrier 30 to which microorganisms that decompose malodors are fixed is disposed in an internal space 7 that is surrounded by the upper surface plate 2, the rear surface plate 3, and the side surface plate 4 including the horizontal surface portion 2a and that opens downward. In addition, a pipe 29 for watering the carrier 30 is provided on the surface of the top plate 2 and through the back surface of the solar cell module 6. These are the main components of the biological deodorization device. An exhaust port 28 for exhaust is provided in the back plate 3. As the water for watering, the on-site treated water can be used, and the flow rate of the water is controlled or controlled by the valve 31.

  As shown in FIG. 18, two (a plurality of) carriers 30 can be disposed in one cover assembly 110, and the treated water supply pipe 32 can be used in common (FIG. 18). Then, the valve 31 is omitted). The water (watering) that has passed through the carrier 30 may be discharged to the sewerage facility (downward) as it is. Unlike the embodiment shown in FIG. 18, only one carrier 30 may be provided in one cover assembly 110. In this case, for example, it is preferable to provide a suction fan to suck and collect the odor gas generated from the on-site treated water and supply it to the one carrier 30.

The carrier 30 is disclosed in, for example, Patent Documents 3 and 4, and is preferably a thin cartridge type so that the carrier 30 can be easily accommodated in the cover lid assembly and can be easily handled. For example, when the treatment scale (of the sewerage facility) is 100,000 m ³ / day, and the residence time of the reaction tank at this time is 8 hr (hours), the effective volume of the reaction tank is approximately 33000 [m ³ ] (= 100000) [M ³ / day] × 8 [hr] / 24 [hr]) When the height of the reaction tank is 5 [m], the effective area of the reaction tank is 6600 [m ² ] (= 33000 [m ³ ]. ] / 5 [m]), and the opening ratio is 50 [%], the opening area of the reaction vessel is 3300 [m ² ] (= 6600 [m ² ] × 0.5). Then, if the amount of air sent to the reaction tank is 1 [m ³ / m ³ · hr], 33000 [m ³ / hr] (= 33000 [m ³ ] × 1 [m ³ / m ³ · hr] )), And the amount of air per opening area (area of the cover lid assembly) is 0.0027 [m ³ / m ² · sec] (= 10 [m ³ / m ² · hr] = 33000 [m ³ / hr] / 3300 [m ² ]) and the area per unit of the cover assembly is 5 [m ² ], the air amount per unit of the cover assembly is 0.014 [m ³ / sec] (= 0.0027 [m ³ / m ² · sec] × 5 [m ² ]). Under such conditions, the required amount of the carrier 30 is 0.28 [m ³ ] (= 0.014 [m ³ / sec] × 20 [sec]) if the contact time is 20 [sec]. The required amount of the carrier 30 may be obtained from the space velocity SV (for example, 200 [hr ⁻¹ ]). On the other hand, when the superficial velocity (linear velocity) is 0.02 [m / sec], the area of the carrier 30 is 0.7 [m ² ] (= 0.014 [m ³ /sec]/0.02 [ m / sec]). Such a superficial velocity is a low value outside the (design) standard in the conventional biological deodorization apparatus. Thus, if the superficial velocity is set low, a low pressure loss can be achieved. The height (thickness) of the carrier 30 is 0.4 [m] (= 0.28 [m ³ ] /0.7 [m ² ]), and a thin carrier with low pressure loss is realized. I can do it. Further, such a carrier can be a cartridge type carrier that can be easily accommodated in the cover lid assembly.

  The material of the cover cover assembly according to the present invention is not particularly limited, but is preferably lightweight from the viewpoint of facilitating installation work, for example, glass fiber reinforced resin (FRP) is preferable. As a material.

  The cover assembly according to the present invention is any one of the cover assemblies described above, wherein the lower side (lower end side) of the upper cover 2 of the cover assembly is in the direction from southeast to south to southwest, preferably southward. It is preferable to arrange and use as described above.

  EXAMPLES Hereinafter, although this invention is demonstrated further in detail based on an Example, this invention is not limited to these Examples.

  (Embodiment 1) Using the cover assembly in the mode shown in FIGS. 1 and 3, the lower side of the slope of the top plate of each cover in the cover assembly is the installation direction shown in Table 1, and the top of each cover The annual power generation amount of the solar cell module when the inclination angle of the face plate is set to the value shown in Table 1 was calculated under the following simulation condition 1. The results are shown in Table 1.

  [Simulation condition 1] The location is Tokyo, the capacity of the solar cell module is 1040 W (130 W × 8), the module temperature coefficient is −0.5% / ° C., and the inverter efficiency is 92%.

  (Consideration 1) According to Table 1, when the inclination angle of the top plate is the same (except in the case of 0 °), the lower side of the inclination on the top plate of the cover is in the southeast-south-southwest direction, particularly in the south direction. It can be seen that a higher annual power generation can be obtained when installed in such a manner than when installed in other directions. It can also be seen that the annual power generation amount increases as the inclination angle increases until the inclination angle of the top plate is about 30 °, but tends to decrease when the inclination angle is exceeded.

  (Examples 2 to 6) Using the cover lid assembly of the aspect shown in FIG. 15, the inclination angle of the top plate and the number of solar cell modules respectively disposed on the horizontal plane portion and the inclined plane portion are changed, The annual power generation amount of the battery module was calculated under the following simulation condition 2. The results are shown in Table 1.

[Simulation Condition 2] The amount of generated power was calculated based on the description on page 91 of Non-Patent Document 1. The influence of the shadow was calculated based on the description on page 76 of Non-Patent Document 1. The amount of solar radiation data described on page 214 of Non-Patent Document 2 was adopted. The location is Tokyo, and the capacity of the solar cell module is 75 W per unit. The length L of the cover cover assembly (cover cover) is 6.2 m (fixed value), which corresponds to the length of the sewerage facility to be covered. The height H is 1.47 m (fixed value). In the winter solstice (shadow magnification K = 2.3) where the length of the shadow is the longest, the passage width is 3 m, the installation interval of the cover assembly is 3.39 m, and the shadow length is not longer than the installation interval of the cover assembly. I made it. The back plate inclination angle θ ₂ (inspection port inclination angle) is 105 ° (fixed value), and the back plate horizontal distance L3 (inclination start distance) is 0.39 m (fixed value). In addition to the length L, the height H, the back plate inclination angle θ ₂ , the back plate horizontal distance L 3 (tilt start distance), the inclined surface portion horizontal distance L 1 (of the cover cover assembly), the horizontal plane portion length L 2 in Table 2 Refer to FIG. 15 for the inclined surface portion length S and the upper surface plate inclination angle θ ₁ (sunlight inclination).

  (Consideration 2) As shown in Table 2, as a result of the power generation simulation, when the inclined surface (six) and the horizontal surface (three) were combined, the annual power generation amount was the largest. From this result, when the installation conditions are determined in advance, as in a sewage treatment facility, it may be more advantageous to combine an inclined surface and a horizontal surface than to install a solar cell module only on the inclined surface. I understand.

  The cover lid assembly and its method of use according to the present invention can be suitably used as means for covering the upper part of the sewerage facility.
