Description
Technical Field
The utility model relates to an integrative electromagnetic response photocatalysis waste water processor of photocatalysis reactor collection electromagnetic response control rotating separation ware for the rotatory stirring of reaction and the electromagnetic response separation of absorption and photocatalytic degradation industry waste water and magnetism photocatalytic material.
Background
Sewage, in general, refers to wastewater from domestic and production discharges that is subject to some degree of pollution. Sewage treatment refers to a process of purifying sewage to meet the requirement of draining a certain water body or reusing the water body. With the development of economy and society, sewage treatment work is more and more important.
The photocatalytic oxidation technology degrades organic matters in the environment into water and carbon dioxide by utilizing visible light or ultraviolet light, and has wide application prospects in the aspects of air purification, sterilization and deodorization, wastewater treatment, self-cleaning and the like. Among the current semiconductor photocatalytic materials, TiO2The photocatalyst has the advantages of stable chemical property, good acid and alkali resistance, no toxicity, strong oxidation capability, abundant sources, low cost, good catalytic performance and the like, is often used as a photocatalyst and is considered to be the photocatalyst with the most application potential at present. The science and technology workers are improving TiO2Much work has been done on photocatalytic activity, but TiO2The nanometer particles still have the defects in the application research of the photocatalytic oxidation treatment of organic wastewater, such as difficult solid-liquid separation, incapability of realizing cyclic utilization and solving the problem of TiO2The solid-liquid separation and the recycling can be realized, so that the cost of the photocatalyst can be reduced, and the application of the photocatalytic technology is promoted.
At present, the problem of separating and recycling the photocatalyst is mostly solved by loading the photocatalyst, and the loaded photocatalyst is mainly used for separating and recycling TiO through physical or chemical action2The photocatalyst is supported on a solid support. Common solid carriers include inorganic materials such as activated carbon, glass spheres, molecular sieves, clays, and the like. The active carbon, molecular sieve, clay and the like are used as carriers, have large specific surface area and promote pollutants by virtue of the adsorption capacity of the carriersThe contact between the photocatalyst and the photocatalyst is poor, so that the photocatalyst in the pore diameter of the carrier cannot effectively absorb ultraviolet or visible light, thereby reducing TiO2Photocatalytic activity. The glass is used as a carrier and has good light transmission, but the small specific surface area of the glass enables the loading amount of titanium dioxide on the glass to be low, thereby reducing the photocatalytic activity of the glass. In addition, although the problem of separation of the photocatalyst can be solved by supporting the photocatalyst on a carrier, it is still difficult to recover the photocatalyst. And magnetic Fe3O4The nano particles and TiO have huge specific surface area and good separation and recovery characteristics2The photocatalyst is compounded, the trouble that nano titanium dioxide particles in water are difficult to separate and recycle is solved by utilizing the advantages of the photocatalyst, so that the prepared composite photocatalyst has the nano TiO2Excellent photocatalytic activity, and easy separation and recovery of the catalyst by an external magnetic field.
