Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a running water purification system and a running water purification method.

[0002]

2. Description of the Related Art Conventionally, efforts have been made to improve water quality by eliminating causes of water pollution in rivers and lakes. However, most of them were able to improve the water quality naturally, so no further efforts were made. However, in recent years, urban congestion has rapidly progressed, and a large amount of domestic wastewater has been introduced into rivers, lakes and marshes, and water pollution of rivers and lakes has rapidly progressed. Since then, the pollution of water quality such as rivers and lakes will continue to progress, and the pollution of water quality will progress to the extent that it naturally exceeds the limit of purifying water quality. Therefore, in addition to naturally purifying the water quality of water such as rivers, we thought of artificially purifying the water quality. However, it has been extremely difficult to purify the water quality in areas with large amounts of water such as rivers and lakes.

[0003]

On the other hand, each part of a running channel such as a river, on the other hand, can be preserved as it is without destroying the peripheral wall surface part of the running channel such as the river, that is, both banks. It is required to go. On the other hand, water is required to purify its quality.
In purifying water quality in areas with a large amount of water, such as rivers and lakes, first form a part of a running water channel or use a natural running water channel as it is. It is necessary to use the surrounding wall surface as it is without any deformation, and to purify only the water in the running water channel to reliably purify the water quality.
The present invention aims to solve the above problems.

[0004]

Allows ozone to be ejected over a wide area in the horizontal direction, raises the ozone bubbles generated there through a layer of far-infrared emitting ceramic crushed stone, sterilizes the ozone bubbles, and treats with far-infrared emitting ceramic crushed stone. A flow channel purification system comprising a layer of far-infrared radiation ceramics crushed stone and an ozone ejector disposed so as to activate water, and the present invention is directed to purifying a flow channel. Make the basin of the running water channel purify the running water along the running water flow path, and start the first stage of the running water purification from the aeration process stage by the aeration area, and then the second stage of running water purification. , The precipitation treatment stage by the sedimentation area, then the third stage of purification of the running water, the flushing water activation treatment step by the flushing water activation area, and the aeration process in the first aeration treatment stage. The amount of dissolved oxygen in the water to be treated is increased by aeration so that the aerobic bacteria generated in the area can decompose organic substances by the surface of the far-infrared emitting ceramic crushed stone In the next settling area, substances that deteriorate water quality such as fine particles and bacterial carcasses mixed in the water to be treated that has been aerated in the aeration area on the upstream side are naturally settled. In the next water flow activation area, ozone can be ejected over a wide area in the horizontal direction, and the bubbles of ozone generated there are raised through the layer of crushed far-infrared radiation ceramics, and sterilized by the bubbles of ozone. Is a method for purifying a running water channel, in which water to be treated can be activated by crushing far infrared radiation ceramics.

In the process, purify the treated water as above,
Then, the water to be treated can be surely activated. Further, in order to purify the flowing water channel, the present invention purifies the flowing water of the flowing water channel along the flow channel of the flowing water channel, and the first step of purifying the flowing water is the aeration treatment step by the aeration area. And then the second stage of running water purification,
Far-infrared radiation ceramics placed in the aeration area at the first aeration process stage after the precipitation treatment stage by the precipitation area, and then the third stage of the purification of running water by the flush water activation process stage by the flowing water activation area In order to enable decomposition of organic matter by aerobic bacteria generated in the area by the function of crushed stone, it is possible to increase the amount of dissolved oxygen in the water to be treated by aeration, and in the next precipitation area , In the aeration area on the upstream side, fine particles that are mixed in the aeration-treated water to be treated, substances that deteriorate water quality such as dead bodies of bacteria, are allowed to settle naturally, and in the next water flow activation area, , Ozone can be ejected over a wide area in the horizontal direction, and the bubbles of ozone generated there rise through the layer of crushed far infrared radiation ceramics In this method, the water to be treated flows down from the aeration area to the sedimentation area because it is a method to purify the water by sterilizing it with ozone bubbles and activating the water to be treated with crushed far infrared radiation ceramics. In the process of flowing down to the water activation area, the water to be treated can be purified as described above, and the water to be treated can be surely activated, and the far-infrared emitting ceramic crushed stone is semipermanent. The ozone bactericidal treatment is very strong but does not remain, so there is no risk of unexpected adverse effects after use. Also, it can be constructed at extremely low cost.
