Photocatalytic reaction gel membrane

Abstract

The invention relates to a photocatalytic reaction gel membrane. The gel membrane comprises a photocatalytic reaction site and a polar group, an area in the periphery of the photocatalytic reaction site is a strong adsorption polar group area, an area outside the strong adsorption polar group area is a non-strong adsorption polar group area, and charges of the strong adsorption polar group area and non-strong adsorption polar group area are both positive or negative; the potential of the strong adsorption polar group area is higher than that of the non-strong adsorption polar group area, and the strong adsorption polar group area is composed of strong adsorption polar groups or formed by gathering weak adsorption polar groups, wherein the weak adsorption polar groups and the polar groups of the non-strong adsorption polar group areas are the same polar groups. The photocatalytic reaction gel membrane can be reused and has high catalytic efficiency and low energy consumption, a supported catalyst is unlikely to fall off, and a high industrial popularization value is achieved.

Description

technical field [0001] The invention belongs to the field of polymer composite materials and relates to a photocatalytic reaction gel film. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous growth of population, a large number of pollutants have been discharged into surface water ecosystems such as rivers and lakes, resulting in the destruction of the ecological environment of the river basin and seriously restricting the sustainable development of the economy and society. affect people's quality of life. Sewage treatment technology and its engineering application have become an essential part of maintaining sustainable social and economic development. Various sewage treatment processes based on physical, chemical and biological principles continue to emerge. For organic industrial wastewater with high toxicity and refractory biodegradation, photocatalytic degradation technology based on chemical principles h...

Problems solved by technology

Using ultraviolet light as the excitation light source, the TiO 2 The photogenerated electrons on the photoanode surface of the membrane turntable are transferred to the cathode surface of the turntable, and the photogenerated electrons react with the saturated dissolved oxygen on the cathode turntable surface to generate H 2 o 2 , the indirect oxidation of organic matter and TiO 2 The photogenerated holes on the surface of the film photoanode rotating disk directly oxidize the organic matter, which improves the degradation efficiency. The rotation of the rotating disk accelerates the exchange and renewal of the electrode surface and the main solution. 2 When the turntable rotates quickly, it is easy to fall off, and the TiO 2 It has a certain hindering effect on light, which hinders its further promotion and application
