<P>PROBLEM TO BE SOLVED: To provide a discharge type gas treatment device capable of controlling the concentration of generated NO<SB>x</SB>when a gas to be treated is subjected to a discharge treatment. <P>SOLUTION: A creeping discharge electrode 1a disposed in a communication passage A in which a gas to be treated containing an object component to be treated is communicated and an alternate current voltage source 12 for applying an alternate current voltage to the creeping discharge electrode to discharge the gas to be treated are provided. A voltage value and a frequency of the alternate current voltage are set to a range that a product of the voltage value and the frequency becomes a set value or less such that the concentration of generated NO<SB>x</SB>generated accompanying the discharge of the gas to be treated becomes a predetermined value or less. <P>COPYRIGHT: (C)2004,JPO |
