    摘要: PROBLEM TO BE SOLVED: To provide a method for treating combustion waste gas capable of economically removing dust and heavy metals from the combustion waste gas and also easy in dust-post treatment. SOLUTION: The combustion waste gas is brought into contact with a heavy metal adsorbent to remove the heavy metals at a high temperature field of 500-800 deg.C at the first part or the latter part of a high temperature dust collector 11 for removing the dust from the combustion waste gas of a waste incinerator 10. The heavy metal adsorbent is clay mineral, allophane, imogolite, zeolite, or the like. The heavy metal absorbent may be fixed in an absorption device 12 or may be applied on a filter element of the high temperature dust collector 11, or may be fluidized in a furnace or sprayed at an inlet of the high temperature dust collector 11.
