Zusammenfassung:	PROBLEM TO BE SOLVED: To remove nitrogen oxides, hydrogen chloride, dioxins or the like efficiently by a dry type waste gas treatment apparatus using a carbonaceous material. SOLUTION: In the waste gas treatment apparatus for treating the waste gas 44 containing at least nitrogen oxides, hydrogen chloride and dioxins by supplying to a reaction tower 40, in which a fluidized bed composed of the flowing-down carbonaceous material is formed inside, in a cross flow to the fluidized bed, the retention time of the carbonaceous material in the reaction tower is in a range satisfying RT
