2, water H
2o, nitrogen N H
3, harmless or few harmful substances such as sulfate.Conventional biological deodorization technique has biofiltration process, biological washing method, bio-trickling method and aeration type bioanalysis.Biological method has the advantages such as processing speed is fast, wide adaptability, non-secondary pollution, but the method there is screening and cultivate bacterial classification difficulty, the defect such as slow takes effect.
Photocatalyst catalytic degradation technology is under photochemical catalyst, to produce electron-hole pair by UV-irradiation, with the H of adsorption
2o and O
2reaction generates the very strong free radical (OH of oxidisability
-) and superoxide ion free radical (O
2 -), can be various organic-inorganic foul gas as class, benzene class, Ammonia, nitrogen oxide, sulfide and other VOC(Volatile Organic Compounds of waking up, volatile organic matter) type organic and inorganic matter be reduced into CO under the effect of photochemical catalytic oxidation
2, H
2o and other nontoxic material.Due in photocatalysis oxidation reaction process without any additive, can not produce secondary pollution, photocatalytic degradation is subject to people's attention gradually.The application of photocatalysis technology aspect odor purification, is mainly the constraint that is subject to activity and efficiency and the photocatalytic coating technology of photochemical catalyst, is difficult to industrialization.
