Performance Test for Odor and VOCs Control Device by Circulation Type UV-TiO₂Photocatalytic Oxidation Process
Abstract
This paper presented experimental results for circulation type UV-TiO2 photocatalytic oxidation process.We have developed UV-TiO2 photocatalytic oxidation process with activated carbon to control odor andVOCs in indoor and industrial applications. In this study, common indoor air pollutants, namely ammonia,formaldehyde, hydrogen disulfide, toluene were selected to investigate their efficiencies for UV-TiO2photocatalytic oxidation. In high concentration test, the decomposition efficiency was high in order asammonia, toluene, formaldehyde, hydrogen disulfide. Three type of individual processes are tested for abilityto increase decomposition efficiency. UV-TiO2 photocatalytic oxidation combined process with activatedcarbon was excellent among the three type processes without reference to gas species. It was consideredthat this circulation type process will overcome short retention time for treatment for UV-TiO2photocatalytic oxidation. It will promise that this circulation type UV-TiO2 photocatalytic oxidation combinedprocess can apply indoor and industrial applications to remove odor and VOCs quickly.
