DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field for preventing water pollution. That is, one aspect of the present invention relates to a collector for removing water pollutants contained in wastewater and wastewater by utilizing the fluidity of the wastewater and the wastewater.
Another aspect of the present invention relates to a collection unit for removing water pollutants by utilizing such fluidity. Another aspect of the present invention also relates to a trapping device for removing water pollutants utilizing such fluidity.

[0002]

2. Description of the Related Art Domestic wastewater and industrial wastewater can be mentioned as typical ones requiring treatment for preventing water pollution. Regarding treatment means for preventing water pollution, various methods such as physical treatment, chemical treatment, biological treatment, and a combination thereof have been developed and already implemented. Either method has a high processing effect. The treated wastewater and wastewater usually flows into the sea through rivers.

[0003] On the other hand, there are considerable wastewater and wastewater that are untreated, such as being discarded, left alone, dumped in the sea, and discharged. In the long term, this will be a major cause of water pollution in groundwater, rivers, lakes and marshes. As a result, many water bodies have deteriorated in quality.

[0004]

It is clear how to solve the above problems.
In other words, all used liquids need only be treated and then discharged. However, considering the trouble and cost required for equipment and management, it is not expected that each of them will voluntarily dispose of used liquid. Even if this is done comprehensively by the administrative side, the burden will be too great. Therefore, the above-mentioned non-treatment disposal does not tend to decrease so much. From the opposite viewpoint, if the technology is an inexpensive and trouble-free water pollution prevention technology, its diffusion rate will increase, and there is hope for prevention of water pollution in public waters.

[0005] Some existing water pollution control technologies can also be expected to reduce equipment costs and management labor. For example,
A filtration method as one of physical treatment means and a microorganism treatment method as one of chemical treatment means correspond to them. However, current wastewater treatment equipment and wastewater treatment equipment are still large-scale in terms of configuration, cost, and installation space. Therefore, this kind of conventional technique has much room for improvement in simplifying and practically using the processing means without reducing the processing effect.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems,
Water pollution prevention technology (water pollutant collection tool, water pollutant collection unit, water pollutant collection device) that can simplify usage, reduce equipment costs, reduce management labor, and save space. It is something to offer.

Action: The water pollutant trap according to the present invention is used by attaching it to the end of the flow channel. The water pollutant trap unit according to the present invention is such that the connector corresponding to the end of the flow channel has water quality. Combined with Pollutant Collector The water contaminant collector according to the present invention has a structure in which the water contaminant collector is connected to the end of the flow channel via a connector. When the water pollutant collecting means of the present invention is applied to a flow path in which drainage or wastewater flows, the following is an example.

Wastewater and wastewater (hereinafter simply referred to as wastewater) contain various miscellaneous solids, and their degree of pollution and turbidity are not uniform. In a series of flow path systems through which wastewater flows, the continuity is maintained by the upstream flow path end opening the downstream flow path side wall or intervening in the flow path. When increasing the solids capture efficiency without disturbing the flow in the flow channel system, for large solids, medium and medium, rather than intensively capturing various large and small solids contained in wastewater in one place It is desirable to set these capturing means at the upstream, intermediate, and downstream portions of the flow channel system and capture in multiple stages, such as for solid content and small solid content. Based on this, it is assumed that the water pollutant trapping means is set in multiple stages in the channel system. When drainage flows from the upstream side to the downstream side in such a flow path system, the water-permeable collection bag attached to the flow path end on the upstream side captures large-sized solids and allows others to pass through, The water-permeable collection bag attached to the middle flow path end captures medium-sized solids and allows others to pass through, while the water-permeable collection bag attached to the downstream flow path end drains water. The remaining solid content is captured and only moisture is passed. Therefore, water pollutants are
It is unlikely that water will flow into lakes and marshes.

In the above, when the filter medium is placed in the water-permeable collection bag, the effect of trapping water pollutants in the wastewater is further enhanced, and chemical treatment (oxidation of pollutants) in the filter medium layer is performed.・ Crystalization) and biological treatment (decomposition of contaminants by microorganisms) are also performed.

The captured water contaminants accumulate in the water-permeable collection bag over time. Therefore, it is necessary to check the pollutant collection status at an appropriate time, remove contaminants from the collection bag, and change the collection bag according to individual cases . In such a case, it is easy to take in water contaminants over a long period of time by using a water-permeable collection bag having a large capacity. In addition, the capturing function of the water-permeable collecting bag does not depend on the size of the capacity. Therefore, the inspection, removal,
With regard to the exchange, it is easy to reduce the number of operations and the number of operations to reduce the burden on management.

Each of the water contaminant collectors and the connecting devices composed of a bag or a tube has a simple structure and is of low cost, and is used when forming a water contaminant collector using these. Equipment costs do not increase. Since the main components are bag-shaped, the space-saving type requires little space. In addition, the water pollutant collector and the connector can be easily applied to a general flow path (eg, a pipe) that is widely used.

[0024]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a water pollutant trap, a water pollutant trap unit, and a water pollutant trap apparatus according to the present invention will be described with reference to the accompanying drawings.

Each of the water pollutant collectors 11 illustrated in FIGS. 1A to 1D includes a collection bag 12, an elastic ring 13, a handle 14, and a hook 15. Collection bag 1
Looking at the relative relationship of each part around the center 2, the elastic ring 1
3 is attached to the periphery of the opening end of the collection bag, handle 14 is integrated with the outer surface (outer peripheral surface) of the elastic ring 13, and hook 15 is attached to the outer surface of the closed end of the collection bag. It means that they are integrated.

The collection bag 12 is flexible and has water permeability. The collection bag 12 is made of a synthetic resin bag material or a cloth bag material. The collection bag 12 may be composed of a double bag or more stacked bags. The water permeability of the collection bag 12 is determined by the number and size of the eyes of the bag material (fabric). Therefore, in order to secure required water permeability, a bag material suitable for the collection bag 12 is selected and made. As a typical example of the collection bag 12, a bag made of a mesh bag made of polyimide resin (nylon) can be given.

The hook 15 on the outer surface of the closed end of the collection bag 12 has a ring shape. Such a hook 15
Is attached to the closed end of the collection bag 12 by tying a synthetic resin or metal ring material with a metal fitting or a string as an example. As another example, the catch 15 may be attached thereto by directly tying a synthetic resin string or a cloth string to the closed end of the collection bag 12. In addition, the hook portion 15 made of synthetic resin or metal may have a bent shape like a hook shape. In some cases, the hook 15 may be omitted from the collection bag 12.

As is self-evident, the elastic ring 13 is deformed in response to an external force, but recovers when the external force is removed. Therefore, as a material of the elastic ring 13, a material having such physical properties is selected from a synthetic resin, a rubber, a metal (preferably a metal having stainless steel and corrosion resistance), and a composite material thereof. Each of the elastic rings 13 in FIGS. 1A and 1D has a perfect circular shape. On the other hand, the elastic ring 13 in FIG. 1B has a vertically long elliptical shape, and the elastic ring 13 in FIG. 1C has a horizontally long elliptical shape. In the ring wall of the elastic ring 13 in FIG. 1 (D), a plurality of stop holes 16 distributed at equal intervals along the circumferential direction are formed. The stop hole 16 corresponds to a stop described later. The elastic ring 13 may have a double ring structure of the inner ring and the outer ring. The inner peripheral surface and / or the outer peripheral surface of the elastic ring 13 may be a gentle conical surface (taper surface).
In this case, the inner diameter of the tapered inner peripheral surface gradually decreases from the front end to the rear end, and the inner diameter of the tapered outer peripheral surface gradually decreases from the front end to the rear end. When the elastic ring 13 having the tapered inner peripheral surface is put on the outer periphery of a flow path end described later, the elastic ring 13 comes into strong contact with the outer peripheral surface of the flow path end and is fixed. When the elastic ring 13 having the tapered outer peripheral surface is fitted into a flow path end described later, the elastic ring 13 comes into strong contact with the inner peripheral surface of the flow path end and is fixed. The above-described circular elastic ring corresponds to a case where an end of a flow path described later has a circular cross-section, but is a case where the end of the flow path is a channel type or a square cylindrical shape. For the elastic ring 13, a rectangular one such as a square is used as the elastic ring 13. Incidentally, in the case of a rectangular (eg, quadrilateral) elastic ring 13 whose one or more sides are curved inward, it is suitable for circumscribing the end of the rectangular flow path, and one or more sides thereof are suitable. If it is curved outward, it is suitable for being inscribed in the rectangular flow channel end.

The handle 14 is made of a rod which is straight or slightly bent in the illustrated example, and is integrated with the elastic ring 13 in such a manner as to rise from the outer peripheral surface of the elastic ring. Such a handle 14 is, for example, an elastic ring 13.
It is made of the same kind of synthetic resin or metal, but does not need to be an elastic body. It is preferable that the handle 14 be made of a hard material. The handle 14 may have a bent shape such as a U-shape, instead of the rod shape described above. The handle 14 is an example of the elastic ring 1.
3 and formed integrally. As another example, the elastic ring 1
In the case of the handle 14, which is separate from the handle 3, the fixing by adhesion (including welding), the fitting of the rod and the hole (the press-fitting), the fixing using a fastener, the combination of two or more of these Such,
It is attached to the elastic ring 13 by a known means. Of course, there is also an elastic ring 13 without the handle 14.

An elastic ring 1 is provided around the opening end of the collection bag 12.
Means for attaching 3 include the following. One is to apply the open end of the collection bag 12 to the inner or outer peripheral surface of the elastic ring 13 and stick it with an adhesive. The other is that the opening end of the collection bag 12 is folded and wound around the elastic ring 13 and the folded piece is sewn to the main body side of the collection bag 12 with a strong thread. Still another is that when the elastic ring 13 has a double ring structure, the opening end of the collection bag 12 is sandwiched between the inner ring and the outer ring to fix it. is there.

Each of the connecting tools 21 illustrated in FIGS. 2A and 2B has a cylindrical basic form. FIG.
In the connection tool 21 of (A), since the upper part on one end side is cut out in an arc shape, an arc-shaped part 22 facing the notch is formed. A raised stopper 23 is provided on the inner peripheral surface of the arc-shaped portion 22. In addition, the connecting tool 21 of FIG. 2 (A) is formed with a plurality of blind holes 24 distributed at equal intervals in the circumferential direction in a cylindrical portion having no notch. This stop hole 24 also corresponds to a stop described later. On the other hand, the connecting tool 21 shown in FIG.
Only four are formed. These connectors 21 are also made of synthetic resin or metal. The connection tool 21 corresponding to the rectangular flow path end is formed into a square shape according to the content described for the elastic ring 13.

Each stop 3 illustrated in FIGS. 3A to 3D
1 is a fixing between the collecting bag 12 with the elastic ring 13 and the connector 21, a fixing between the connector 21 and the end of the flow path,
It is used when the water pollutant collector 11 is attached to the end of the flow channel, such as when the water pollutant collector 11 is fixed to the end of the flow channel, and corresponds to the above-described stop holes 16 and 24. Such a stopper 21 is also made of synthetic resin or metal. Of these, FIG.
The stopper 31 of FIG. 3A is composed of a screw without a head,
The stop 31 of (B) consists of a screw with a head. On the other hand, the stopper 31 of FIG. 3 (C) is composed of a pin having a head at one end or a bulging stopper at the other end. The stopper 31 shown in FIG. 3D is also made of the same pin as that shown in FIG. 3C, but has a slit in the form of a slit on the side of the stopper. Each of the stopper holes 16 and 24 for receiving the stopper 31 has a different hole shape depending on the mode of the stopper 31. For example, the stopper 31 is shown in FIGS.
In the case of using screws such as described above, each of the stop holes 16 and 24 is formed of a screw hole. When the stopper 31 is made of a pin as shown in FIGS. 3C and 3D, each of the stopper holes 16 and 24 is a simple hole. In this case, the inner diameter of each of the stop holes 16 and 24 is slightly smaller than the outer diameter of the bulging retaining portion of the pin.

The filter medium 41 is used, for example, as shown in FIG. 1 (A), by being placed in the collection bag 12 of the water pollutant collector 11. Such a filter medium 4
As for 1, natural or organic materials and synthetic inorganic or organic materials are known or well-known in this type of technical field. Therefore, specific examples of the filter medium 41 include zeolite, crushed stone, gravel, activated carbon, silica, charcoal, coal, vegetable fiber, synthetic fiber, wood chips (wood chips), and the like. In a specific example of the present invention, among these, those having a high adsorptivity to fats and oils, zeolite, and the like are employed as the filter medium 41. The filter medium 41 of another material can be used alone or in a combination of two or more. The water pollutant collector 11 may be used without putting the filter medium 41 in the collection bag 12.

The water pollutant trapping unit according to the present invention comprises a combination of a water pollutant trap 11 and a connector 21. That is, the water pollutant collection unit is shown in FIG.
The various water pollutant collectors 11 described with reference to (A) to (D) and the various connectors 21 described with reference to FIGS. 2A and 2B are arbitrarily combined. It is composed of

The water pollutant trapping apparatus according to the present invention is constituted by the water pollutant trapping unit described above, and is applied to each of the flow paths of the flow path system exemplified in FIGS. Things. 4 and 5, a small flow path 51 composed of a conduit and a large flow path 52 composed of a side groove are mutually continuous with the flow path 51 being upstream and the flow path 52 being downstream. doing. In addition, one end (discharge end) of the flow path 51 opens the side wall of the flow path 52 so that the end face thereof coincides with the inner surface of the side wall. On the other hand, in the channel system shown in FIGS.
Not only is one end (discharge end) of the flow path 51 opening the side wall of the flow path 52, but one end of the flow path 51 is connected to the flow path 52.
Is intervening within. Hereinafter, examples in which the apparatus of the present invention is applied to these channel systems will be specifically described.

In the specific example of FIG. 4, the water pollutant collector 11 of FIG. 1A or 1B and the connector 21 of FIG. 2A are used. Among them, the connecting member 21 has an outer diameter that closely fits into the end of the flow path 51, and the outer diameter of the elastic ring 13 of the water pollutant collector 11 that closely fits inside the connecting member 21. have. In addition, one end (discharge end) of the flow path 51 is made to coincide with the inner surface of the side wall of the flow path 52 as described above. In this case, when attaching the water pollutant collector 11 to the end of the flow path 51, the connecting tool 21 is attached to the inner peripheral surface of the end of the flow path 51, and then the elasticity of the water pollutant collector 11 is increased. Ring 13 is mounted in fitting 21. Specifically, the connector 21 is fixed to the inner peripheral surface at the end of the flow path 51 by the stopper 31 shown in FIG. 3A or 3B, such a stopper 31 and / or a known adhesive. Is done. Thus, the connecting tool 21 is connected to the flow path 51.
When fixed to the end, the arcuate portion 22 on the distal end side of the connection tool 21 protrudes from the end of the flow path 51. Therefore, the inside of the arc-shaped portion 22 (the tip surface of the connecting tool 21 and the stopper 23
The water contaminant collector 11 is attached to the end of the flow path 51 by fitting the elastic ring 13 into (between). In this case, the elastic ring 13 held between the distal end surface of the connector 21 and the stopper 23 does not move in the axial direction of the flow path 51.

In the specific example shown in FIG. 5, the water pollutant collector 11 shown in FIG.
The connection tool 21 of (B) is used. Among these, the connector 21 has an outer diameter that closely fits in the flow path 51, and the elastic ring 13 of the water contaminant collector 11 closely fits the outer periphery of the connector 21. have. Also in this case, when the connector 21 is attached to the inner peripheral surface at the end of the flow path 51 by the same means as described above, the connector 21
Is protruded from the end of the flow path 51. Therefore, after the elastic ring 13 is put on the outer peripheral surface of the distal end portion of the connecting device 21, the elastic ring 13 is fixed to the distal end portion of the connecting device 21 with the stopper 31 shown in FIG. Thus, the water pollutant collector 11 is attached to the end of the flow path 51.

In the specific example of FIG. 6, the same type as the specific example of FIG. 4, such as the water pollutant collector 11 of FIG. 1A or FIG. Used. However, the connector 21 has an outer diameter that closely covers the outer peripheral surface of the end of the flow path 51, and the elastic ring 13 of the water pollutant collector 11 has an outer diameter that fits tightly in the connector 21. doing. Further, the flow path 51 is different from the previous two examples, and one end thereof is interposed in the flow path 52. In this case, when attaching the water pollutant collector 11 to the end of the flow path 51, the connector 21 is attached to the outer peripheral surface of the end of the flow path 51, and then the elastic ring of the water pollutant collector 11 is attached. 13 is mounted in the connection tool 21. Specifically, when the connecting tool 21 is fixed to the outer peripheral surface of the end of the flow path 51 by the same means as described in the specific example of FIG. 51, the water contaminant collector 11 is inserted into the arc-shaped portion 22 (between the distal end surface of the connector 21 and the stopper 23). Attached to the end.

In the specific example of FIG. 7, in the same channel system as in FIG. 6, the water contaminant collector 11 of FIG.
The same components as those described in the specific example of FIG. 5 are used, such as the connector 21 of FIG. Therefore, in the specific example of FIG. 7, the water pollutant trap 1 is similar to that described in the specific example of FIG.
1 is attached to the end of the channel 51.

In each of the above embodiments, when the elastic ring 13 and / or the connecting member 21 have at least one of the tapered inner peripheral surface and the tapered outer peripheral surface, the end of the flow path 51 and the connecting member 21 And the connection tool 21 and the elastic ring 13 can be fixed using such a tapered surface. This is because a strong frictional action occurs between the inner and outer peripheral surfaces of both members fitted to each other. Therefore, when adopting such a fixing means, the above-mentioned stopper 31 and adhesive may be omitted. When the elastic ring 13 has an elliptical shape as shown in FIG. 1B in the specific example of FIG. 4 or the specific example of FIG. 6, the elastic ring 13 is deformed into a perfect circle when fitted into the perfect circular arc-shaped part 22. With the restoring force
2 makes strong contact with the inner surface. In such a case, the self-fixing function of the elastic ring 13 in the arcuate portion 22 is enhanced. Similarly, in the specific example of FIG. 5 and the specific example of FIG. 7, when the elastic ring 13 is an elliptical shape as shown in FIG. 1B or FIG. , And strongly contacts the outer peripheral surface of the connector 21 due to the restoring force. Also in such a case, the self-fixing function of the elastic ring 13 with respect to the connection tool 21 is enhanced, so that the stopper 31 for the elastic ring 13 may be omitted. In addition, in the specific example of FIG. 5 and the specific example of FIG. 7, when a stopper hole similar to the stopper hole 16 of the elastic ring 13 is The hole 16 and the stop hole on the side of the connector 21 are made to coincide with each other, and the stop 16 shown in FIG.
Can be employed. The stop hole in this case does not need to be a screw hole.

In the case of the apparatus of the present invention described above, FIGS.
When drainage or wastewater (hereinafter simply referred to as drainage) flows from one flow path 51 side to the other flow path 52 side in the flow path system illustrated in FIG.
2 to capture water contaminants as follows. That is, when drainage flows as in the flow path 51 → the collection bag 12 → the flow path 52, only water pollutants (contaminated solids / contaminated solids) larger than the eyes of the bag are captured and all others pass. This causes the collection bag 12 to perform a filtering action. More specifically, the collecting bag 12 having flexibility and a large number of eyes traps only a predetermined size of the pollutant while deforming according to the amount of drainage, the size of the pollutant, the amount of the pollutant, and the like. Therefore, the drainage becomes clear by the amount filtered by the collection bag 12, and the flow path 52
Flows to the side. In addition, in the case of the collection bag 12 containing the filter medium, not only the water pollutant in the wastewater is captured more through the layer of the filter medium 41, but also the captured water pollutant is treated chemically and biologically. As an example, if the filter medium 41 has a high adsorptivity to fats and oils, the fats and oils form nuclei and mix with oxygen to crystallize, so that the fats and oils are effectively captured and treated. Will be As another example, if the filter medium 41 is a zeolite that is called an organic exchanger, nitrogen compounds and phosphorus compounds that cause eutrophication of the wastewater are removed from the wastewater. In addition, since the amount of water in the two flow paths 51 and 52 changes, the layer of the filter medium 41 appears on the water surface or sinks below the water surface. Filter medium 41
When the layer of the filter medium 41 is exposed to the air and exposed to air, the microbial treatment by aerobic bacteria becomes dominant. When the layer of the filter medium 41 is below the water surface, the microorganism treatment by anaerobic bacteria is often performed. The trapping pollutant which repeats the dry and wet with the increase and decrease of the water amount also promotes the oxidizing action. Therefore, even if some of the trapped contaminants (oxidized substances) escape from the collection bag 12 and flow into the downstream area, the dissolved oxygen in that area is not consumed much.

When a large amount of water pollutants accumulate in the collection bag 12 due to long-term use, the water pollutant collector 11 is once removed and the trapped pollutants are appropriately disposed of. At the time of this removal, in both specific examples of FIGS.
5 to pull out the water pollutant trap 11 from the inside of the connector 21. In both of the specific examples of FIGS. 5 and 7, the stopper 31 of the elastic ring 13 is loosened and then the water pollutant trap 1
1 will be extracted from the outer peripheral portion of the connection tool 21. In this case, not only the grip 14 is gripped, but also the operation tool (eg,
It is preferable that the water contaminant collector 11 is pulled up by hooking a hook (hand hook) or a bent wire (thick line) on the hook 15 of the collection bag 12. In this way, it is possible to prevent the collection bag 12 from being damaged by the weight of the captured contaminants, and the operation can be performed easily. Thereafter, as shown in FIG. 8, the collection bag 12 is inverted using the operation tool (hand hook) 61 or the like, and the captured contaminants in the bag are taken out.

In the specific example shown in FIG. 4, when the water contaminant trap 11 is attached to the end of the flow path 52, the operation is as follows. That is, since the flow path 52 has a square groove shape, a corresponding (substantially square) water contaminant collector 11 is used, and the connector 21 for this is also a square one. . The connecting tool 21 is attached to the inner peripheral surface of the end of the flow path 52 by the above-described fixing means using a stopper or an adhesive, and the water pollutant collector 11 is also connected to the connecting tool 21 by the above-described fixing means. Mounted inside or outside the When the connecting tool 21 is not used in such a case, the water pollutant collector 11 is directly attached to the inner peripheral surface of the end of the flow path 52.

According to the present invention, the water pollutant collecting device, the water pollutant collecting unit, the water pollutant collecting device, etc.
It has the following effects.

The water contaminant collector according to the present invention has a simple structure mainly composed of a collecting bag having water permeability and an elastic ring attached to the periphery of the opening end of the collecting bag. This is a very low-priced instrument for capturing water pollutants flowing through the flow path for a long period of time, does not cause bulkiness, and can be easily applied to various flow paths. When such a water contaminant collector has a handle or a hook portion, the convenience in handling the device increases. When a filter medium is placed in the collection bag of the water pollutant collector, the physical treatment effect of trapping water pollutants is further enhanced, and the chemical treatment and biological treatment of the collected pollutants are performed. Processing is also possible.

The water pollutant collecting unit according to the present invention is a combination of the water pollutant trap and the connector. The fittings in this case make the attachment of the water contaminant collector to the ends of the various flow paths simple and reliable. Not only is the water pollutant collector ultra-low-priced, but the connection is also ultra-low-priced with a simple tubular configuration. Of course, when this unit is also applied to the flow path, there is no structural bulk.

The water pollutant trapping device according to the present invention has a structure in which the water pollutant trapping unit is mounted on a flow path, that is, the water pollutant trapping tool flows through the connector. It is of a configuration mounted on the roadside. Since this is mainly made of an ultra-low-priced water pollutant collector and connector, the usage is simple and space-saving, and the equipment cost is not increased. Further, this device has a predetermined collecting function even if it is left as it is after being provided at the end of the flow path, so that no troublesome management is required. Moreover, since a large amount of water pollutants can be captured by the collection bag for a long period of time, the number of times of processing the contents of the collection bag can be reduced. This apparatus purifies wastewater and wastewater flowing from the upstream area to the downstream area through the flow path and discharges the wastewater to the downstream area, thereby contributing to the prevention of water pollution.
