Description
Technical field
The present invention relates to sewage treatment field, is specially a kind of light catalytic waste water processing device.
Background technology
Photocatalytic redox is using n-type semiconductor as catalyst, such as TiO2、ZnO、Fe2O3、SnO2、WO3Deng.TiO2Due to
Chemical property and spectrochemical property are sufficiently stable, and nontoxic inexpensive, and the source of goods is abundant, so photocatalytic redox removes depollution
Thing is usually with TiO2As photochemical catalyst.Photochemical catalyst redox mechanism is mainly the irradiation of catalyst light, absorbs luminous energy, hair
Raw electron transition, generation " electronics-hole " is right, the pollutant to being adsorbed in surface, directly carries out redox, or oxidation table
Hydroxyl-the OH of face absorption, the hydroxyl radical free radical OH for generating strong oxidizing property aoxidize pollutant.Utilize TiO2Photocatalytic degradation
Pollutant in water, compression ring border becomes one of hot spot of environmental area research.Various countries environmental science worker this field into
Go extensive and deep exploration, achieve many gratifying achievements, and applied in terms of environmental protection.Numerous studies are demonstrate,proved
Real, the organic matter such as hydro carbons and polycyclic aromatic hydrocarbon, halogenated aromatic compound, dyestuff, surfactant, pesticide, oils, cyanide can
Light-catalyzed reaction is effectively performed, decoloration, detoxification, mineralising are non-toxic inorganic small-molecule substance, so as to eliminate the pollution to environment.
