Abstract
Ozone generated from an ozonizer is added to a polluted gas containing harmful substances, which is generated from a polluted gas source. Then, the ozone-added polluted gas is allowed to flow through an adsorbing layer containing a high-silica adsorbent that adsorbs both ozone and harmful substances. The harmful substances contained in the polluted gas are converted into harmless substances within the adsorbing layer by the action of the ozone.
