In the present specification, “purification” means that any property of water existing in the water area changes, and does not mean a change in a specific property.

  In this specification, “fence” means a two-dimensional surface, which may or may not be closed to the water area, may not reach the bottom of the water, and is flexible. It does not matter whether or not it has. Further, the “fence” may be extended in a substantially vertical direction from the water surface of the water area toward the bottom of the water, or may be extended substantially in parallel with the water surface, that is, in a substantially horizontal direction.

  In the present specification, the “water purification member” mainly means a material having a function of purifying water, for example, an adsorbent such as salts, nitrogen, phosphorus, heavy metals, organic solvents, radioactive substances, for example, natural or synthetic It is a member that provides zeolite, a microorganism carrier that decomposes organic matter, such as activated carbon and carbon fiber.

  In the present specification, the “water flow rate adjusting member” mainly has a function of adjusting the passage of water through the member, or is a suspension substance (SS), fine-grained component of earth and sand, blue powder It is a member that provides a material having a function of filtering suspended matters such as algae, red tides, and plankton microorganisms.

FIG. 3 illustrates the first aspect.
The float member 31 is made of substantially cylindrical foamed polystyrene or hollow plastic, but the material is not particularly limited as long as it floats on water. For example, it may be a tube of polystyrene foam wound with a blue sheet. A plurality of such float members 31 can be connected in the length direction. The connection may be by connecting the ends of the adjacent hollow plastic floats with a rope. For example, the rope may be passed through the center of the float member 31 or a plurality of peripheral edges may be provided. You may carry out by running a rope along a length direction. The size of the cylindrical float member 31 can be, for example, a diameter of 670 mm and a length of 1150 mm.

  In the first aspect, a base material 33 made of a net is connected to the float member 31. The float member may be connected to not only one side surface portion of the base material but also two or more side surface portions of the base material. Moreover, you may connect on the substantially plane of a base material. The base material 33 made of a net can be, for example, a ball-proof net made of polyethylene or a geogrid. The ball-proof net may be a lattice-shaped polyethylene ball-proof net having a diameter of about 4 mm and 40 × 40 mm. The connection of the base material 33 to the float member 31 is not particularly limited. However, when the float member 31 is a cylindrical foamed polystyrene, the float member 31 is divided into two at the maximum diameter, and the base material 33 is sandwiched between them. The outer periphery of the float member divided into two can be tightly bound by the string 32. Further, a weight such as a metal chain can be attached to the end of the base material, or it can be fixed to the water bottom with an anchor or the like.

  As shown in FIG. 1, the water flow rate adjusting member 10 is a net, a knitted fabric, a woven fabric, a nonwoven fabric, or a water-impermeable sheet 13 fixed to a substantially rectangular reinforcing frame 11 provided with holes 12 including a plurality of eyelets. it can. The auxiliary frame may be flexible as long as it has a predetermined tension, and the auxiliary frame and the nonwoven fabric may be fixed by a method of sewing with a sewing thread or the like. Moreover, you may insert a nonwoven fabric etc. between two auxiliary frames. Further, the shape of the reinforcing frame is preferably substantially rectangular in order to form a unit, that is, to have compatibility with the water purification member described below. It may be a shape.

  For example, use water-impermeable sheets or finely woven fabrics to limit the inflow and outflow of water, and use non-woven fabrics to allow a certain amount of inflow and outflow. When allowing inflow and outflow, a coarse knitted fabric or net can be used. These materials are not particularly limited, and are, for example, polyester woven fabric or non-woven fabric. Here, it should be noted that the water flow rate adjusting member can also function as a filter, an adsorbent, or a microorganism carrier. That is, even the name “water flow rate adjusting member” may have not only the function of water flow rate adjustment but also the function of water purification. The reinforcing frame 11 is provided with, for example, a plurality of holes 12 that can be eyelets, and a string is passed through the holes, and the string is further passed through the lattice of the base material 33 to bind the strings. Thus, the water flow rate adjusting member 10 can be fixed to the base material 33. Such a connection can be made, for example, through a part of a binding band, Insulok (registered trademark), a thread, a toothpaste (tension thread), a wire, a rope, a safety pin, a clip or a hook instead of a string. The water flow rate adjusting member 10 can be, for example, a square having sides of 40 cm to 2 m.

  As shown in FIG. 2, the water purification member 20 includes a single mesh made of a finer mesh in an outer bag 23 made of a mesh fixed to a substantially rectangular reinforcing frame 21 having holes 22 including a plurality of eyelets. Alternatively, it has a double-structured bag structure in which an adsorbent or the like is accommodated in a plurality of inner bags 24.

  Here, the structure of the hole 22 and the reinforcing frame 21 of the water purification member 20, the fixing method to the base material 33, and the size are the same as those of the water flow rate adjusting member 10 described above. However, in the water purification member 20, instead of the above-described nonwoven fabric 13 or the like, an adsorbent or the like having a function of adsorbing microorganisms 25, for example, a plurality of contact filter media made of porous synthetic resin, oyster shells are reused. Zeolite, activated carbon, oil adsorbent that adsorbs nitrogen, phosphorus, heavy metals, organic solvents, radioactive materials, etc. and also carries microorganisms The outer bag 23 is made of a mesh made of a wire material having a coarser and higher strength and containing one or a plurality of inner bags 24 made of a fine mesh packed so as not to spill. It is fixed to. Zeolite is a preferred adsorbent because it can be recovered after nitrogen adsorption into fertilizer. Here, it should be noted that the material accommodated in the single or plural inner bags 24 can be appropriately replaced depending on the state of purification. That is, even if the name is “water purifying member”, the same function as the water flow rate adjusting member may be exhibited depending on the presence / absence and type of material in the inner bag.

  The water purification fence according to the present invention is characterized in that the water flow rate adjusting member 10 and the water purification member 20 are each provided as compatible units. As a result, depending on the situation of water purification, these units can be replaced or increased / decreased by simple operations as appropriate, so that the amount of water flowing through the fence, the filterability of suspended suspended matter, the adsorption Optimal purification becomes possible by adjusting the amount of the agent and the microbial carrier. For example, when surrounding a water area to be purified by four water area purification fences having a water depth of 6 m, a water flow rate adjusting member 10 of an impermeable sheet is arranged up to a water depth of 1 m, and a non-woven water flow rate adjusting member 10 is set to a water depth of 1 m to 5 m. And the adsorbent water purification member 20 are alternately arranged, and the water flow rate adjusting member 10 of the net is all arranged at the water depth 5 m to 6 m, or neither the water flow rate adjusting member 10 nor the water purification member 20 is arranged. be able to. In this case, it is possible to optimize the purification by appropriately changing the position and type of such compatible units according to the degree of purification, for example, by increasing or decreasing the ratio of the number of water purification members 20 of the adsorbent. Can be

  As shown in FIG. 4, in the second aspect of the present invention, a predetermined number of water purification member units 20 and a predetermined number of water flow rate adjustment member units 10 are directly connected without using a substrate made of a net. It is characterized by being. These connections can be the same as the connection of the purification member unit 20 and the water flow rate adjustment member unit 10 to the base material.

  As shown in FIG. 5, in the third aspect of the present invention, the water purification member unit 20 or the water flow rate adjustment member unit 10 having a width wider than the certain width is attached to each float 51 having a certain width. Are connected in a row in the vertical direction and have a strip shape. And the water purification fence is comprised because this strip-shaped thing adjoins right and left. Here, the units adjacent to the left and right have reinforcing frames overlapping each other, but the units are not connected to each other. The third aspect is effective when the function as the water purification fence is not affected only by such overlapping of the units.

In the third aspect, the float 51 is provided with a hook 53, and the floats 51 are connected to each other via a connecting rope 52. The hook 53 penetrates the hole of the water purification member unit 20 or the water flow rate adjustment member unit 10 and connects the float 51 and the unit. The units adjacent in the vertical direction are connected by the connecting means (strings) 54 as in the second embodiment.
In addition, as a modification of the third aspect, a strip-shaped one in the third aspect may be one in which each unit is connected via the base material in the first aspect (not shown).

  The contribution of the third aspect in construction of the water purification fence and replacement of the unit is significant. Because it is not necessary to connect the left and right units adjacent to each other, the strips that are connected to the floats 51 in a single row in the vertical direction without any diving work are folded to the size of the unit. Are placed on the ship for each float 51, and this is laid in the water area in order for each float. Also, when replacing the unit, only one strip-shaped object is lifted to the ship for replacement, and then submerged in water. Because it can.

  As described above, as shown in FIG. 6, the water purification fence according to the present invention can be installed by extending in a direction substantially orthogonal to the water surface. At this time, as shown in FIG. 7, the water purification fence can be fixed to the bottom of the water by using an anchor or the like. In the aspect of FIG. 7, since the float is located under water and in water, it is convenient without obstructing the passage of the ship.

Moreover, as shown in FIG. 8, it can also install so that the substantially flat surface of this water purification fence may extend substantially in parallel with the water surface. By laying the water purification fence of the present invention at a location close to the water surface or substantially parallel to the water surface, for example, in water purification plants, harmful substances contained in rainwater and the like can be removed, and water quality can be suitably maintained. it can.
Further, as shown in FIG. 9, the water purification fence can be laid so as to be in contact with the water bottom. The embodiment shown in FIG. 9 is suitable for removing a precipitating harmful substance. Furthermore, by collecting the float, the water purification fence can be easily collected.

  In the water purification fence according to the present invention, the water purification unit and the water flow rate adjusting member unit are appropriately selected according to the state of water purification, and the respective predetermined numbers are easily arranged or changed on a substantially plane, Since the area of the water purification area (amount of adsorbent and microbial adhesion carrier) and the area of the water flow rate adjustment area (water permeability and filterability) can be optimized, it can be suitably used for water area purification.
