Device for photocatalyzing water by using nanoporous titanium oxide film

Abstract

The invention discloses a device for photocatalyzing water by using a nanoporous titanium oxide film. The device comprises a photocatalytic reaction tank, wherein a supporting barrel is arranged at the center of the bottom side of the photocatalytic reaction tank; a disperser is connected to the top end of the supporting barrel through a bearing; four water spraying heads are in array distributionon the side surface of the disperser; a snowflake-shaped light source is arranged above the four water spraying heads and on the side surface of the inner part of the photocatalytic reaction tank; four sliding slots 2 are in array distribution above the snowflake-shaped light source and on the side surface of the inner part of the photocatalytic reaction tank; and electric telescopic rods are arranged at the bottom ends of the four sliding slots 2. The device can adjust the position of the titanium oxide film to change the light intensity so as to control the reaction speed, degrades wastewater, sterilizes pollutants in the wastewater, can increase the oxygen content of the wastewater, effectively removes organic pollutants in the wastewater and kills bacteria and prevents secondary pollution of the wastewater.

Description

technical field [0001] The invention relates to the technical field of photocatalytic water, in particular to a device using a nanoporous titanium oxide film to photocatalyze water. Background technique [0002] As people's demand for water is increasing, at the same time, people discharge a large amount of domestic sewage, agricultural sewage and industrial wastewater directly or indirectly into natural water bodies, which seriously pollutes water resources, and the actual available fresh water is getting less and less. , has seriously hindered the development of human society. Water pollution not only reduces the actual amount of fresh water available, but also causes great harm to human health. Traditional water treatment methods use physical methods, chemical methods and biological methods. Ultrafiltration and dialysis technology require a large investment and are inconvenient to maintain. Adsorption technology can remove odors and adsorb harmful substances in water, but...

[0002] As people's demand for water is increasing, at the same time, people discharge a large amount of domestic sewage, agricultural sewage and industrial wastewater directly or indirectly into natural water bodies, which seriously pollutes water resources, and the actual available fresh water is getting less and less. , has seriously hindered the development of human society. Water pollution not only reduces the actual amount of fresh water available, but also causes great harm to human health. Traditional water treatment methods use physical methods, chemical methods and biological methods. Ultrafiltration and dialysis technology require a large investment and are inconvenient to maintain. Adsorption technology can remove odors and adsorb harmful substances in water, but it must be replaced or analyzed after saturation. Secondary pollution occurs, and the treatment speed is slow, the purification is not thorough, and a large amount of sludge is generated during the treatment process, causing secondary pollution
