Abstract

　Provided are a gas treatment device and a gas treatment method which can reduce nitrogen oxides in gas which is to be treated, reliably and with low processing-costs.　This gas treatment method for reducing nitrogen oxides in nitrogen oxide-containing gas which is to be treated is characterised by irradiating ultraviolet light from an ultraviolet light radiating lamp onto a mixed gas of a carrier gas and a raw material gas which can generate ammonia radicals, thus generating ammonia radicals, and then mixing the ammonia radicals into the gas which is to be treated, thus reducing the nitrogen oxides in the gas which is to be treated.
