Background technology
Japanese scientist A.Fujishima in 1972 and K.Honda find the TiO of illumination
2Monocrystalline electrode energy water of decomposition causes the interest of scientific worker to the photosensitized oxidation reduction reaction, has promoted the interest of organism and inorganics photoredox reaction thus.
Photocatalytic oxidation is the method that ultraviolet radiation (UV) and oxygenant are used in combination.Under the exciting of UV-light, the oxygenant photolysis produces stronger free radical (as OH) and the active oxygen of oxidation capacity.Hydroxyl radical free radical has high oxidizing electrode current potential (2.80v), is only second to F (3.06v).Its electron affinity power is 596.3KJ, easily the high cloud density point of attack.This has determined the OH attack to have rapidity, and by transfer transport and addition reaction, can not have reacting with pollutants in sewage of selection.Be carbonic acid gas, water by breaking the chain scission of link, oxidizing the contaminants into, the direct mineralising of part material becomes salt, and can not produce secondary pollution.This just makes it have very strong photoxidation restoring function, various organic compound of oxidable decomposition and part inorganics, can destroy the cytolemma of bacterium and solidify the protein of virus, thus can the many single Persistent organic pollutants that can't decompose with oxygenant of oxidation.The common use of UV-light and oxygenant makes photochemical catalytic oxidation no matter on oxidation capacity still is speed of reaction, considerably beyond utilizing photoinduction to produce hydroxyl radical free radical OH, is that engineering of water treatment is paid close attention to more a kind of novel advanced oxidation device in recent years all.
Because photocatalytic oxidation has the cheap characteristic such as nontoxic of good chemical stability, mechanical stability, fast light burn into and is widely used in anti-pollution paint, sterilization, sun power sensitization battery and photocatalysis treatment environmental pollutant etc.But, because TiO
2Particle suspension is in liquid phase, and difficult separation and recycling has limited it in Application of Sewage, causes the research in a lot of sewage of photocatalyst catalyzed oxidation field still to rest in the laboratory scope, does not have the real society that moves towards.Be badly in need of a kind of waste disposal plant that can utilize photocatalysis oxidation reaction.
Summary of the invention
