EXPERIMENT OF ACTIVE CARBON AND NANO-TITANIUM DIOXIDE PHOTOCATALYSIS TECHNIQUE TO ELIMINATE TINY CONTAMINANTS IN AIR

摘要

Now progress of techniques indoor air contaminants of controlling is rapid, and many techniques have been applied to interrelated materials and equipments. For practical application, disposing air tiny contaminants still exists some problems. In this article, a new purification technique is introduced, namely Active Carbon and Nano-titanium Dioxide Photocatalysis technique, and its capability for purifying air contaminants is compared with active carbon purification web and Nano-titanium Dioxide Photocatalysis purification web. The result shows the effect of the new purification technique is obvious. Meanwhile air resistant of the web and factors that influence purification efficiency are analyzed, and the result shows the new purification technique exerts the advantages of active carbon purification technique and Nano-titanium Dioxide Photocatalysis purification technique, as purification web with new purification technique possesses stronger capability of absorption and decomposition on organic and inorganic contaminants and less resistant ofairflow, and decreases concentration of contaminants andenhances the purification efficiency and avoids the producing of new contaminants, and realizes the regeneration of active carbon on the same place and prolongs the life-cycle of active carbon etc..
