Comparison of photocatalytic oxidation and biological deodorization for treating exhaust gases
Classification :company newsDATE:2018-10-29

Biological deodorization is also known as biological decomposition method, biological decomposition method is the use of circulating water will odor gas pollutants in water, and then cultured microorganisms in the water culture bed, the water pollutants will be degraded into low-toxic substances, deodorization efficiency can reach 70%, but affected by microbial activity, the cultivation of microorganisms can only In order to improve the treatment efficiency and stable operation of one or several similar gases, it is necessary to add medicines frequently, control the pH value, temperature and so on. In this way, the operation cost is relatively high, and the input of manpower is also more, and once the organisms die, it will take a long time to re-culture. The photocatalytic oxidation method uses high energy UV ultraviolet light. In the photocatalytic purification equipment, the molecule chain of malodorous substances is cracked and oxidized to low molecular harmless substances by changing the material structure. The deodorization efficiency is 99%. The deodorization effect is much higher than the emission standard of malodorous substances issued in 1993 (GB14554-93). It can handle high concentration mixed gases such as ammonia, hydrogen sulfide, methyl mercaptan, methyl sulfide, benzene, styrene, carbon disulfide, trimethylamine, dimethyl disulfide, etc. The internal light source can be used for three years, the life of the equipment is more than ten years, the purification technology is reliable and very stable, the purification equipment needs no daily maintenance, and can be put into operation only by switching on the power supply. It is often used and has low running cost and no two pollution. Scope of application: deodorization and purification of organic and inorganic odors such as food processing plants, meat processing plants, slaughterhouses, poultry feed farms, paper mills, sewage treatment plants, garbage transfer stations, excrement treatment. Deodorization and purification of organic and inorganic odor gases such as refineries, rubber factories, leather factories, printing factories, chemical factories, Chinese and Western medicine factories, metal foundries, plastic recycling factories, spraying solvents, etc. Photocatalytic treatment of waste gas technology has been studied and practiced for many years, and has been introduced into the field of industrial waste gas purification on a large scale in China. A series of industrial photocatalytic organic waste gas purification devices have been formed. Photocatalytic deodorizer is a kind of environmental protection equipment, which uses biological spraying to pretreat and then enters the photocatalytic purification device. Under the action of catalyst, organic waste gas can be converted into CO2 and H20 at room temperature. At present, the device has been widely used by users at home and abroad, and has achieved good purification effect. Industrial waste gas treatment methods such as adsorption method, plasma method, catalytic combustion method, and so on, the symptomatic waste gas treatment method also depends on the scene. After more than 10 years of scientific research and experiment on industrial photocatalytic air purification process, Habitat Photocatalyst purification device has obtained many scientific research patents for many years, and has profound technical support.
