[0002]

2. Description of the Related Art Conventionally, there is one in which a photocatalyst is immersed in pooled water or dirty water, and a catalyst layer purifies the pooled water or dirty water by light emitted from the outside.

[0003]

However, in this conventional purification method, since the waste water cannot be forcibly passed through the photocatalyst layer forcibly to purify it, water-bloom and turbidity occur in the reservoir and the water tank. With respect to such severe sewage, there is a problem that the effect of purification cannot catch up and good purified water cannot be obtained. In addition, since there is no one that has been improved in purification efficiency and has been downsized, there are problems that it is not suitable for use in places where traffic is inconvenient and it cannot be installed easily by one person. In addition, there is a problem that the purifying action is not sufficiently performed at nighttime or inside dark dirty water such as pooled water in a tank.

The present invention has been made in order to solve the above-mentioned conventional problems, and the purpose thereof is to positively work even in heavy sewage or inside night or dark sewage. (EN) It is an object of the present invention to provide an excellent purifying device which has a structure capable of performing a purifying action and which can be downsized so that it can be easily installed even in a place where traffic is inconvenient.

The purification chamber consisting of pellets is provided with a pump chamber for forcedly passing sewage taken in from the outside into the purification process chamber, so that the sewage taken in one after another is activated by being irradiated with ultraviolet rays. It is continuously purified by passing it through the pellet bed.

Therefore, according to the invention of claim 1,
Since the sewage is forced to pass through the pellet layer containing the photocatalyst by itself, the sewage can be purified extremely efficiently as compared with a conventional purification device that does not forcibly move the sewage in contact with the photocatalyst layer. Further, since the purification efficiency is improved, the size of the device can be reduced, and it is possible to easily install the device anywhere by hand, for example, to easily clean the sewage even in a place where traffic is inconvenient.

In the water purifying apparatus according to the second aspect of the present invention, the purifying chamber is formed by inserting an ultraviolet germicidal lamp into a protective glass tube for protection and stacking pellets containing titanium dioxide around the protective glass tube. Due to the vertical arrangement with respect to the pump chamber, the sewage pumped from the pump chamber receives the ultraviolet rays and comes into contact with the titanium dioxide only while passing a long distance of the ultraviolet germicidal lamp.

Therefore, according to the invention of claim 2,
While the sewage receives sufficient UV light while passing a long distance of the UV germicidal lamp and comes into contact with titanium dioxide, the sewage can be efficiently purified by decomposing and sterilizing organic substances and erasing water-bloom etc. . Since the pellets are arranged so as to surround the ultraviolet germicidal lamp, the photocatalyst efficiently receives ultraviolet rays, and an extremely good purification action is performed even in the nighttime zone and dark sewage. In addition, the overall size, especially the size of the purification treatment chamber, is made compact so that it can be easily stored and transported, and it can be made compact after achieving improvement in purification efficiency. The effect of easily purifying sewage can be obtained.

In the water purification device according to the third aspect, since the tourmaline is contained in a part of the sedimentary layer of the pellets, it is possible to further improve the quality of the purified water by reducing the water cluster when purifying the sewage. It is possible to obtain effects such as being able to.

In the water purifying apparatus according to the fourth aspect, since aeration is performed from below the pellet accumulation layer,
The dissolved oxygen concentration of purified water can be increased to obtain purified water suitable for fish inhabitation. Further, by performing aeration of ozone, it is possible to further improve the sterilizing effect in a shorter time and obtain purified water of good quality.

In the water purifying apparatus according to the fifth aspect of the present invention, since the float is connected to the frame, the purifying apparatus can be set to an optimum water depth, or even one person can move to the optimum place during installation or use. This is extremely easy to carry out, and the effect that the purifying device can be used under optimum conditions is obtained.

Further, 21 is a control unit and 22 is an air generation unit, but an ozone generator may be connected instead of the air generation unit depending on the state of the dirty water.

First, the control unit 21 energizes the water purification device A immersed in dirty water to turn on the ultraviolet germicidal lamp 11 and drive the submersible pump 7 in the pump chamber 3. Further, air is supplied to the pump chamber 3 from the air generator 22 via the pipe 9. When the ultraviolet germicidal lamp 11 is turned on, the pellets 16 are irradiated with ultraviolet rays to photoactivate titanium dioxide as a photocatalyst. Therefore, the sewage in the vicinity of the pellet 16 is purified by decomposing and sterilizing organic substances and microorganisms.
In addition, sewage is sterilized by the ultraviolet rays that are irradiated, and further purification proceeds. In addition, the tourmaline layer reduces the cluster of water and improves the quality of purified water.

The submersible pump 7 in the pump chamber 3 continuously pushes into the purifying treatment chamber 4 for purifying the wastewater taken in from the outside through the water suction port 5 through the water discharge port 8. The sewage that has flowed in from below the purification processing chamber 4 pushes up the purified water above while passing through the sedimentary layer 15 of pellets, and drains it to the outside through the drainage port 6. Further, the air supplied to the pump chamber 3 goes out into the purification treatment chamber 4 by the submersible pump 7 and is aerated to increase the concentration of dissolved oxygen in the purified water. This series of operations can be continuously performed during the operation of the submersible pump 7 to efficiently purify the sewage.

Is disposed vertically with respect to the pump chamber, so that the passage distance of sewage can be lengthened and the purification action can be promoted. Since the pellets 16 are arranged so as to surround the ultraviolet germicidal lamp 11, the pellets 16 can be integrated as a whole and made compact. Also, since the pellets are provided by coating a transparent glass sphere with a photocatalyst, the ultraviolet light irradiated by the photocatalyst penetrates the glass sphere and penetrates the gap formed between the glass spheres to the far glass sphere. Since the photocatalyst layer reaches the photocatalyst layer, the photocatalyst action is performed every corner of the photocatalyst layer, and the sterilization and decomposition action of the filtered water by the photocatalyst is sufficiently performed. Further, since the irradiated ultraviolet rays can be efficiently used, it is possible to reduce the number of ultraviolet lamps and downsize the device. It can proactively promote the purification action even in sewage or dark sewage where the breeding of blue-green algae is severe. Due to the above effects, it is possible to form the entire size into a small size with good portability without deteriorating the performance of purification, so that it can be easily used anywhere, for example, in an inconvenient place for transportation. . Also, by connecting the float, it becomes possible to set the purification device to the optimum water depth, and it becomes extremely easy for one person to move to the optimal place during installation or use, so that the purification device can be used under optimal conditions. The effect of being able to do so can be obtained.
