JP 2004-298708 A Japanese Patent No. 3328349

  The purification material is a grain of about several millimeters made of ceramic or the like. For example, a purification material made from ceramics acts as a catalyst for decomposing ammonia and can be used for a long time. However, if it is used as it is in a large water receiving tank such as a pool, it is not easy to collect it. Therefore, it was purified by placing it in a metal container, leaving it in the bottom and leaving it overnight. However, there is a problem that the water in the vicinity where the purification material is placed is only purified and cannot be purified uniformly.

  An object of the present invention is to improve the purification efficiency by improving the holding body that encloses the purification material so that it can move freely in the liquid.

In the present invention (6), the holding body is made of a hydrophilic material, and the total specific gravity is equal to or less than the liquid to be purified at the time of drying, but is equal to or more than the liquid to be purified at the time of moisture absorption. This is the purification element of the present invention (4).
The present invention (7) is the purification element according to any one of the present inventions (1) to (6), wherein the holding body is a thin plate type.

The present invention (8) is the purification element according to any one of the present inventions (1) to (6), wherein the holding body is an elliptical sphere.
The present invention (9) is a purification method characterized by using any one of the purification elements of the present invention (1) to (8) suspended in a liquid to be purified.
The present invention (10) is the purification method of the present invention (9), wherein a sterilizing material is added to the holder of the purification element for use.

  The purification element according to the present invention (1) can be purified simply by being introduced into a water receiving tank in which the liquid to be purified is stored. In particular, when the specific gravity of the purification element is equal to or less than the specific gravity of the liquid to be purified, the purification element enters a floating state. That is, even when the liquid to be purified is stationary or flowing at a low speed, the purification element can move around and the purification efficiency can be increased. By introducing a plurality of purification elements, the purification elements spread over the entire liquid to be purified and can be purified uniformly. Moreover, the collection | recovery of the purification elements after completion | finish of purification only collects them in a water-receiving tank, and can be performed easily.

  According to the present invention (2) and (5), the liquid to be purified can be efficiently purified. Further, when the liquid to be purified is water or hot water and a soft material is used as the holding body, it can be used as a play equipment. That is, when children are playing with this playground equipment, the opportunity for the water to come into contact with the purification material held inside the playground equipment increases, and the water in the pool, bathtub, etc. can be purified.

  By introducing the purification elements according to the present invention (3) and (6) into the liquid to be purified, it is possible to uniformly purify from the upper part to the lower part of the liquid to be purified while slowly precipitating. It is preferable to use a hydrophilic material having a low water absorption rate.

  According to the present invention (4), the purification efficiency can be increased because the mesh holding body enters and exits from all sides and collides with the purification element held therein.

  According to the present invention (7), the contact area between the purification element and the liquid to be purified is increased. Purifying efficiency can be improved by uniformly distributing the purifying material on the surface that is largely in contact with the liquid to be purified. Also, when the holder or lightweight body is made from a hydrophilic material and used while slowly precipitating as in the present invention (3) and (6), the sedimentation rate is reduced because the contact area with the liquid to be purified is large. Can be late. Therefore, the purification efficiency can be improved even when the liquid to be purified is uniformly purified from the upper part to the lower part.

  According to the present invention (8), even when the specific gravity of the purification element sinks greatly, it moves around while rolling on the bottom surface. Therefore, even if the liquid to be purified is stationary or flowing at a low speed, it can be efficiently purified. By introducing a plurality of purification elements, the purification elements spread over the entire bottom surface and can be purified uniformly.

  According to the present invention (9), the liquid to be purified can be efficiently purified.

  According to the present invention (10), it also has a bactericidal effect and is effective for use in an ornamental water tank or aquaculture farm. In particular, by using a purification material that also has the function of decomposing ammonia into ammonium and nitrogen oxides, an environment in which fish can be grown can be maintained for a long time. Therefore, the interval for exchanging water and seawater can be extended. What is necessary is just to use powders, such as an oyster shell and a shell, as a disinfection material.

  The best mode of the present invention will be described below.

(Purification element)
FIG. 1 is a sectional view of a purification element that is an embodiment of the present invention.
(a) is a purification element in which a plurality of purification materials 11 are wrapped with a net-like holding body 12. As the purifying material 11, a material having a large surface area as described in Patent Document 1 and Patent Document 2 is used. When this is wrapped with the mesh-shaped holding body 12 and put into the liquid to be purified, the liquid to be purified enters and exits through the gap between the mesh-shaped holding body 12 so as to come into contact with the purification material 11.

  The specific gravity of the entire purification element is preferably equal to or less than the specific gravity of the liquid to be purified. When this purification element is put into the liquid to be purified, the purification element becomes floating. That is, even if the liquid to be purified is stationary or flowing at a low speed, the purification element moves around. For this reason, there are many opportunities for the liquid to be purified to enter and leave through the gaps between the mesh-like holding bodies 12 and to contact the purification material 11, and the purification efficiency can be increased. Further, by introducing a plurality of purification elements, the purification elements spread over the entire liquid to be purified and can be purified uniformly.

  When purifying water, the specific gravity of the purification element is preferably 1.0 or less. The specific gravity of the purification material 11 is generally greater than 1.0. Therefore, the total specific gravity is set to 1.0 or less by using a plastic having a small specific gravity such as polyethylene or polypropylene as the net-like holding body 12.

  (b) is a case in which a part of the holding body 13 is made into a net and the purification material 11 is wrapped around the part. A lightweight body 14 is placed in the other part of the holding body 13 so that the specific gravity of the entire purification element is equal to or less than the liquid to be purified.

  (c) shows a case where a granular lightweight body 15 is put together with the purifying material 11 inside the mesh-like holding body 12.

  In (a) to (c), the holding bodies 12 and 13 or the lightweight bodies 14 and 15 may be made of a hydrophilic material. At that time, the total specific gravity is equal to or lower than that of the liquid to be purified during drying, and is equal to or higher than that of the liquid to be purified during moisture absorption. By introducing this purification element into the liquid to be purified, it is possible to uniformly purify from the upper part to the lower part of the liquid to be purified while slowly precipitating. It is preferable to use a hydrophilic material having a low water absorption rate.

  When the purification element floats in the liquid to be purified and stays for a long time, it is preferable that the outer shape (holding body) of the purification element is a thin plate type. At this time, the contact area between the purification element and the liquid to be purified increases. Purifying efficiency can be improved by uniformly distributing the purifying material 11 on the surface that is largely in contact with the liquid to be purified. In addition, when the holders 12 and 13 or the lightweight bodies 14 and 15 are made of a hydrophilic material and used while being slowly settled, the sedimentation rate can be slowed due to the large contact area with the liquid to be purified. . Therefore, the purification efficiency can be improved even when the liquid to be purified is uniformly purified from the upper part to the lower part.

  When the specific gravity of the purification element is large and sinks in the liquid to be purified, it is preferable to make the outer shape (holding body) of the purification element elliptical. In this case, the purification element moves around while rolling on the bottom surface. That is, even when the liquid to be purified is stationary or flowing at a low speed, the purification element can move around and be efficiently purified. Further, by introducing a plurality of purification elements, the purification elements spread over the entire bottom surface and can be purified uniformly.

(Pool and bathtub purification method 1)
FIG. 2 is a schematic view showing an embodiment of a method for purifying a pool and a bathtub.
In the present embodiment, the water purification unit 22 is provided in a part of the main water tank 21 used as a pool or a bathtub. A purification element 23 is inserted into the water purification unit 22, and is separated by, for example, a wire mesh 24 so that the purification element 23 does not flow out of the water purification unit 22.

As the purification element 23, it is preferable to use one having a specific gravity equal to or less than that of water. At this time, the purification element 23 floats in the water purification unit 22. When a portion other than the water purification unit 22 is used as a pool or a bathtub, the vibration is transmitted to the water purification unit 22 and the purification element 23 moves around in the water purification unit 22. As a result, the water is purified by entering the purification element 23 and coming into contact with the purification material.
The size of the purification element 23 is not particularly limited. By making the size easy to handle, the charging and collection can be performed easily.

  The purification element 23 may be put into the entire main water tank 21 when not used as a pool or a bathtub. As the purification element 23, a holding body or a lightweight body is made of a hydrophilic material, and the total specific gravity is equal to or less than the specific gravity of water at the time of drying and equal to or greater than the specific gravity of water at the time of moisture absorption. It is preferable to use it. Further, it is preferable to use a hydrophilic material having a low water absorption rate. When this purification element 23 is put into the main water tank 21, the entire water in the main water tank 21 can be uniformly purified while being slowly precipitated.

In this embodiment, a purification water tank 31 is provided separately from the main water tank 21 used as a pool or a bathtub. The purification element 23 is placed in the purification water tank 31 and is purified by supplying water with a pump 32. As the purification element 23, the specific gravity is preferably equal to or less than the specific gravity of water. At this time, the purification element 23 which is in a floating state in the purification water tank 31 is moved around by the water supplied by the pump 32. That is, even if the water supply speed by the pump 32 is not high, for example, even a flow that is not felt by the human body can be sufficiently purified. Further, the power consumed by the pump 32 can be reduced.

(Pool and bathtub purification method 3)
