BACKGROUND OF THE INVENTION The present invention is designed to separate and remove oil floating or spilled on the surface of water, such as the sea, the shore, or the shore, and other pollutant particles or pollutants floating on or near the surface of water to improve the water quality. The present invention relates to a water quality environmental purification material for purification. In detail, when used, it spreads in a stable surface form on the water surface, and it is possible to collect, separate, and remove oil and pollutants, and easily fold when not in use, when pulling up from the water surface, or when discarding. Or, it relates to a water quality environmental purification material that can be put together in a small size.

2. Description of the Related Art In recent years, the pollution and destruction of the water quality environment of the sea, harbors, rivers, swamp lakes, ponds, dams, etc. has been remarkable, and purification and improvement of these water quality environments are strongly demanded on a global scale. In particular,
Contamination of the sea and rivers by oil spilled from vessels such as tankers and oil fields, and pollution of the water quality environment by various oil components contained in domestic miscellaneous wastewater and commercial and industrial wastewater have become major social problems, but they are still insufficient. The current situation is that there is no satisfactory method for separating and removing oil, and it is difficult to prevent it. Also,
Not only pollution of the water environment by oil but also pollution of the water environment by other floating particles and pollutants has become a serious problem.

For example, when an oil spill accident occurs due to a ship on the sea or the like, the oil spilled on the sea is surrounded by an oil fence, and then a gelling agent is sprayed over the wide surrounding area to gel the oil. Generally, a method of collecting the oil floating in the sea or a method of directly pumping the oil floating on the sea to a drum or the like loaded on a ship and transporting it to the land is used. However, when spraying the gelling agent directly on the sea, it is extremely uneconomical to spray a large amount of the gelling agent over a wide area, and moreover, it is necessary to collect and collect the agglomerated oil over a wide range. It is complicated and time-consuming. Also, when oil on the sea is directly pumped up and collected in a drum can, a large amount of seawater is pumped together with the oil, so most of the contents of the drum can are occupied by seawater, and oil is efficiently used. It is not recovered and is still extremely inefficient.

On the other hand, for the purpose of recovering oil that has been spilled or dumped on the surface of the sea or the like, and for protecting cultured fish and shellfish from such spilled oil, the absorption and separation of oil with an oil absorbing material arranged in a plane A device has been proposed, for example, an oil fence in which a plurality of oil-absorbing materials are attached to a flat mesh body (Japanese Patent Laid-Open No. 48-
No. 94230), an oil-proof device in which polypropylene fiber mats are arranged and installed in the mesh of the mesh so as to create a space (Japanese Utility Model Publication No. 46-32698), and a large number of net-woven ropes covered with an oil adsorbent. An oil adsorbing net (Japanese Utility Model Publication No. 49-129171) in which the floating material is fixed is known.

However, in the case of the above-mentioned oil fence, since the flat net-like body to which a plurality of oil absorbing materials are attached is simply used by spreading it on the water surface as it is, the net-like object arranged on the water surface is subjected to severe waves during stormy weather. Under the influence of, it becomes difficult to maintain the planar shape and the oil absorption action tends to be reduced. Further, the oil-proof device is provided with edge ropes on opposite side surfaces of a mesh body to which a polypropylene mat is attached so that the oil-proof device can withstand deformation caused by its waves even in the case of stormy weather. However, such an edge rope alone is still susceptible to deformation when used on a rough water surface, and its surface structure cannot be maintained sufficiently stable. In the case of the oil adsorbing net, since a large number of floating materials are fixed over the entire surface of the net, it is possible to maintain a certain planar shape even when used in rough weather.
However, in this oil adsorption net, since the floating material is fixed to each mesh, it is extremely complicated and time-consuming to manufacture, and many floating materials are used when not in use. It is bulky and requires a large storage space. Moreover, the adsorption area of the oil adsorbent is not so large for its bulkiness,
Does not show sufficient oil absorption function. Furthermore, conventionally known techniques for separating and removing pollutant particles and pollutants other than oil floating on or near the water surface are still not sufficiently satisfactory.

[0006]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to prevent a significant deformation even when used on a rough water surface and to float on or near the water surface while maintaining a stable planar shape. Oil and other pollutants can be smoothly separated and removed, while on the other hand, when not in use such as during storage,
It is an object of the present invention to provide a water quality environmental purification material that can be reduced in size without being bulky when it is pulled up from the water surface or disposed of.

[0007]

As a result of continuing studies to solve the above-mentioned problems, the present inventor has found that, mainly from a sheet-like member capable of separating and removing oil and other pollutant components floating on the water surface, In this water environment purification material, a rope is arranged around the surface member, and a plurality of floating materials are attached to the rope so as to be movable in the length direction of the rope, and the periphery of the floating material and the surface member. If the rope is tightened or loosened so that the surrounding diameter of the flat member can be changed, the flat member due to waves or the like can be used even when used on a rough water surface. It is possible to obtain a water environment purification material that does not undergo significant deformation and that can stably separate and remove oil on the water surface while maintaining a stable surface form, and that is not bulky and small when stored. Found. Further, the present inventor has completed the present invention by finding that the same result can be achieved also by a planar member having floating members attached to at least two opposite sides.

That is, the present invention provides a sheet-like member or sheet-like member having at least one of the function of absorbing oil, adhering to oil, aggregating oil, and adhering to other floating pollutant particles or pollutant components. A water quality environmental purification material having a rope arranged in a surrounding manner, a plurality of floating materials attached to the rope, and a connecting means for connecting the floating material and the planar member, wherein the rope changes the surrounding diameter of the planar member. It is possible to tighten or loosen, and the multiple floating members are arranged in the length direction of the rope so that when the rope is tightened, the adjacent floating members come close to or abut each other, while when the rope is loosened, the distance between the adjacent floating members becomes large. It is a water quality environmental purification material characterized by being attached to a rope so that it can be moved to.

Furthermore, the present invention provides a sheet-shaped member and a sheet-shaped member having at least one of the function of absorbing oil, adhering to oil, coagulating oil, and adhering to other floating pollutant particles or pollutant components. It is a water environment purification material characterized by comprising a floating material attached to at least two opposite sides.

Although not limited thereto, the present invention will be described below with reference to the drawings for understanding the content of the present invention. FIG. 1 is a view showing a typical example of the water environment purifying material A of the present invention, in which a planar member 1 has a suitable mesh body 2 having an oil absorbing ability,
The mat 3 having at least one of the function of adhering oil, the function of coagulating oil, and the function of adhering other floating pollutant particles or pollutant components is attached to the mat 3. A rope 4 is arranged around the planar member 1 so as to surround the planar member 1, and a plurality of floating members 5 are attached to the rope 4 so as to be movable in the length direction of the rope 4. . The rope 4 can change the surrounding diameter with respect to the planar member 1 by the tightening / relaxing means 6. When the rope 4 is tightened to reduce the surrounding diameter, the adjacent floating members 5 approach each other. Upon contact, the surrounding diameter of the plurality of floating members 5 with respect to the planar member 1 becomes smaller. On the other hand, when the rope 4 is relaxed and its surrounding diameter is increased, the spacing between the adjacent floating members 5 is increased, and the surrounding diameter of the plurality of floating members 5 with respect to the planar member is also increased. Further, the floating member 5 and the periphery of the planar member 1 are connected by a connecting means 7 such as a string.

In the water environment purification material A of the present invention, the planar member 1 having at least one function of oil absorbing ability, oil adhering ability, oil aggregating ability and other adhering ability of floating pollutant particles or pollutant components is a rope. 4 is surrounded by a plurality of floating material groups, and the connecting means 7 is connected to the surrounding ring of the floating material.
Since it is attached via, even if it is placed on the surface of the water under severe weather with severe waves, it will bend greatly,
It does not curl or deform, its surface morphology is kept stable, and the oil absorption capacity, oil adhesion capacity, oil aggregation capacity and / or the adhesion capacity of other pollutant particles and components of the surface member 1 are effective. Can be demonstrated. At that time, in the floating material group that surrounds the planar member 1, adjacent floating materials may be in contact with each other or may be slightly spaced apart. on the other hand,
When the rope 4 is loosened by the tightening / releasing means 6 when the water environment purifying material A is not used, transported, or pulled up from the water surface, the space between the adjacent floating materials 5 is opened, thereby purifying the water environment. The material A can be folded freely and can be made small without being bulky.

The connecting means 7 for connecting the floating member 5 and the periphery of the planar member 1 has its length depending on the size and shape of the planar member 1 and the surrounding diameter of the rope 4 with the floating member surrounding it. It is good to choose, and it is preferable to have a margin in its length so that some play may occur. The floating member 5 and the periphery of the planar member 1 may be non-detachably attached or detachably attached by the connecting means 7.

When the floating member 5 and the planar member 1 are detachably attached to each other, one end of the connecting means 7 is fixedly attached to the floating material 5 and the other end of the connecting means 7 is attached to the surface. Even if it is detachably attached to the periphery of the plate-shaped member 1, or one end of the connecting means 7 is fixedly attached to the periphery of the planar member 1, and the other end of the connecting means 7 is attached to or detached from the floating member 5. Both ends of the connecting means 7 may be detachably attached to the floating member 5 and the periphery of the planar member 1.

When the floating member 5 and the planar member 1 are removably attached to each other, for example, oil adheres to, absorbs or solidifies the planar member 1 and the planar member 1 is no longer usable. At this time, the rope 4 to which the floating material 5 is attached can be removed from the planar member 1, and the rope 4 with the floating material can be attached to a new planar member 1 for reuse. Moreover, at that time, by selecting the length of the connecting means 7, the entire length of the rope 4, the number and size of the floating members 5 attached to the rope 4, and the like, the rope 4 with floating member can be formed into one kind of planar member 1. In addition to this, it can be attached and used for another planar member 1 having a different size or shape from the planar member.

Depending on the size and shape of the planar member 1, a plurality of planar members can be held by one rope 4 with a floating material, as shown in FIG. 2, for example. Further, the rope tightening / loosening means 7 is, for example, as shown in FIG.
Two or more may be provided on one rope. Furthermore, not all of the floating members 5 attached to the rope 4 may be connected to the periphery of the planar member 1, for example, as shown in FIG. 2, every other floating member 5 or other forms. It may be connected to the periphery of the planar member 1. In addition, as shown in FIG. 3, for example, a plurality of water quality environment purification materials such as those described above in which ropes with floating material are arranged and attached around the surface member 1 are further connected to form a large area water quality purification material. You may form.

The sheet-like member used in the present invention has an oil absorption capacity,
Any one can be used as long as it has at least one function of the oil adhering ability, the oil coagulating ability and the adhering ability of other floating pollutant particles or pollutant components, but two or more of those functions can be used. It is preferably provided. When the viscosity of the oil that flows out or is discharged to the water surface is low, the oil can be absorbed and separated and removed by the oil absorbent, but when the viscosity of the oil is high and it is in a paste form,
The oil absorbing material cannot sufficiently absorb and remove it, but rather, it is effective to attach the paste-like oil to the planar member and separate and remove it. Then, when the oil is absorbed by the planar member or is attached to the planar member to be separated and removed, when an oil coagulant is used together, the oil absorbed or adhered to the planar member is solidified, It is extremely effective because it seldom drops again on the water surface. In that case, the oil flocculant may be contained or supported on the planar member in advance, or may be simultaneously sprayed on the water surface during the oil separation and separation treatment.

The shape and structure of the sheet member 1 are not particularly limited. For example, as shown in FIG. 4, the mesh member 2 is made of synthetic fiber such as polypropylene fiber or polyamide fiber, or natural fiber or the like having an oil absorbing ability or oil. A mat 3 having at least one function of adhering ability, oil aggregating ability and adhering ability of other floating pollutant particles or pollutant components is regularly or randomly arranged and fixed, and a planar member as shown in FIG. There is one in which the whole 1 is formed from one piece of cloth 8 having the above-mentioned function or a net-like body (for example, a rush net).

Further, in this case, if the mat 3 having the above-mentioned function has a napped portion 9 composed of a large number of fibers or threads on the upper surface or the upper and lower surfaces of the mat 3, as shown in FIG. The surface area of the mat becomes extremely large, and the oil absorbing ability, oil adhering ability, oil aggregating ability and the adhering ability of other floating pollutant particles or pollutant components are increased, and the purification of the water quality environment can be further promoted. The napped portion 9 may be in a state in which its tip is cut as shown in FIG. 6, may be in a loop shape, or may be in any other shape, and has a length of It can be appropriately selected depending on the situation. Moreover, the length of the napped part 9 may be the same or may be mixed. Furthermore, the napped part 9 may be made of the same material or a plurality of different materials.

Further, as the mat 3 which constitutes the planar member 1 in the water environment purifying material A of the present invention, a napped mat as shown in FIG. 6 which is manufactured by using threads or fibers having a small oil absorbing capacity is used. In this case, even though the removal separation rate by absorption of oil is not so high, a paste-like oil having a high viscosity is attached to the napped portion 9 of the mat 3, or other water pollution particles or components are attached to the napped portion 9. It can be separated and removed. Then, as long as the water environment purification material of the present invention is not made to be extremely bulky, a small number of other floating materials may be attached to the portion of the planar member as needed.

The structure for attaching the floating material 5 to the rope 4 may be any structure as long as the floating material 5 can move smoothly in the length direction of the rope 4 depending on the tightening or loosening of the rope 4. Well, for example, as shown in FIG.
A through hole 10 having a diameter larger than that of the rope 4 is provided on the floating member 5, or a ring body 11 having a diameter larger than that of the rope 4 is provided on the floating member 5 as shown in FIG. The rope 4 may be passed through the ring 11. The type, thickness, material, structure and the like of the rope 4 and the floating material 5 can be appropriately selected according to each situation.

The rope tightening / relaxing means 6 may be any means capable of tightening or loosening the rope and fixing the rope in a predetermined tightening or loosening state, for example, The tightening / relaxing metal fitting having such a function may be used, or the rope may be tied, or the rope may be simply tied at the position where the tightening / releasing means is attached.

The connecting means 7 for connecting the floating member 5 and the periphery of the planar member 1 is preferably formed of a string, a chain, or other wire material. At that time, the connecting means 7 may be irremovably attached to both the floating member 5 and the planar member 1 as described above, or may be detachably attached to one or both of them. When the detachable connecting means 7 is used, for example, a clip, a pinch, a hook, or another attaching / detaching member may be provided at the end of the connecting means 7.

Further, instead of the above-mentioned water quality environment purifying material in which a rope with a floating material is attached around the planar member, the floating material is directly attached to at least two opposite sides of the planar member as a water quality environment purifying material. As a typical example thereof, the one shown in FIG. 9 can be cited. The purifying material A of FIG. 9 is one in which the floating material 5 is directly attached to the two opposite sides of the slash net 12 having the napped portion made of synthetic fiber such as nylon fiber or polypropylene fiber or natural fiber. When this purifying material A is placed in a river as shown in FIG. 9, oil floating on the water surface or in the vicinity thereof and other pollutant particles and components are removed from the net 1.
It can be absorbed or attached to 2 to purify the water environment. In the purifying material A shown in FIG. 9, the slash net 12 can of course be replaced with the mesh body 2 to which the mat 3 as shown in FIGS. 1 to 4 is attached, or other planar member.

In the water environment purification material of the present invention shown in FIG. 1 to FIG. 6 and FIG. 9 described above, if a weight 13 having a weight that does not sink the whole water environment purification material is attached to the planar member, For example, as shown in FIG. 10, a part of the planar member can be located below the water surface, so that not only the water surface but also the pollutant components floating below the water surface are absorbed by the planar member. It becomes possible to separate and remove by the ability and adhesion. In this case, the weight 13 may be attached over the entire width of the planar member or may be attached only to a part thereof, as long as the entire water environment purification material is not submerged.

The water quality purification material of the present invention is used on the sea, on the coast,
Float freely in the water quality environment such as the shore, rivers, lakes, dams, water intakes such as tap water and industrial water, or with one or more sides fixed to the shore or other structures. Can be used. Further, the water environment purification material of the present invention can be used by surrounding it as a fence so that it does not further diffuse into a body of water in which oil or other pollutant components are flowing out or floating, or , By directly covering the floating or diffusion part of oil or other pollutant on the water surface with the water purification agent of the present invention,
Oils and pollutants can be absorbed, adhered and aggregated in the water environment purifying material for separation and removal. Moreover, when the contaminated oil on the water rushes to the coast, the shore, other shores, etc., or the seafood farm, or when such a concern is expected, the water environment purification material of the present invention Can be placed on the shore or in a farm to prevent damage from oil pollution. Further, when the water environment purification material of the present invention is placed in a specific water area for a long period of time to purify the environment, useful microbes become attached to the surface of the purification material to thereby inhabit. It is possible to purify water quality.
