Abstract

(57) [Summary] [Problem] Purifying nationwide rivers that are undergoing pollution is an issue that cannot be neglected. SOLUTION: The apparatus is moved by a river water flow, and dust in the river is removed by a ceramic and a photocatalyst TiO2 put in a strainer / cage to continuously purify the water quality.

Description

[Detailed description of the invention]

[Technical field to which the invention belongs]

 River water purification using photocatalyst TiO2 and ceramic

[0002]

[Prior art]

 Water purification of rivers has recently attracted attention, in addition to natural purification by shore plants such as kayaks and reeds, in recent years, sanitizing pottery (ceramics) into waterways to aid purification and purification using negative ion fibers. When water is taken from water, the sediment is settled to remove contaminants, and the supernatant water is forcibly filtered with ceramics and chlorinated.Generally, drinking water is used as drinking water. The fact is that energy is used. Activated carbon is also commonly used for water purification, but submerging bincho charcoal in waterways has been practiced in some parts of the country. Recently, the mainstream of water purification is to filter. According to this method, the filter had to be backwashed or clogged as needed, or replaced. General purification did not improve water quality enough to remove contaminants. There was no removal of chloroethylene or the like, and it was only a sterilization and sterilization treatment of Escherichia coli and the like.

[Problems to be solved by the invention]

 Water purification of rivers is an issue that cannot be neglected as river pollution progresses. In the vicinity of Lake Biwa, Otsu, the pollution of Lake Minami-Biwa due to domestic wastewater flowing into the area has been regarded as a problem, and organic pollution such as chloroethylene in rivers all over Japan has been showing signs of worsening again. The challenge is continuous and effective river purification.

[0004]

[Means for solving the problem]

 Install a water purification device that uses TiO2 and ceramics to purify river water. In order to continue not only river purification and waste removal but also water quality improvement, the name of the document Drawing The purification device as shown in Fig. 1 is submerged in the river flow to purify the river.

[0005]

[Embodiment of the invention]

 The height of the purification device is the depth of the river, and the Caga is rotated more by the rotor using the flow of the river. The lumps of TiO2 and ceramics in the Cage continuously purify the water quality of the river. River dust is backwashed by the river water when the Cage is inverted and discharged out of the system. Due to the continuous flow, the Cage rotates between the three-point rotors, and water purification and dust collection are repeated and continued.

[Example of the invention]

 The lumps of ceramic for purifying water and the TiO2 of the photocatalyst are contained in a strainer / cage. The cage spins around a three-point roller. The wheel is turning a water wheel, and the water wheel is turning a river. Cage is a river flow. The Cage moves upward from the bottom so as to cut off the water flow of the river, scoops the dust from the river, receives light from the upper surface of the river, purifies it with the function of a photocatalyst, releases the dust when the Cage is inverted, and separates the separated dust out of the system. Collected in one place.

[Effect of the invention]

 Since the photocatalyst TiO2 is contained in the cage, the river is purified. At that timing, when the Cage moves on the upper surface of the river, the TiO2 receives light and decomposes water, and enters the river with oxygen added to the TiO2, so that purification is continued. It decomposes lower organic chlorine compounds such as trichlorethylene and tetrachloroethylene, nitrogen oxides, sulfur dioxide, and aldehydes on the TiO2 surface. Ceramics increase the purifying capacity of the device by miniaturizing water and increasing its activity. Therefore, as long as there is a flow in the river and the amount of water is present, the purification device keeps rotating and the TiO2 keeps its function, so that continuous river purification is performed.
