The present invention relates to an incineration ash containing mercury that can effectively remove mercury even when the waste contains mercury, and is suitable for the intensive treatment of incineration ash obtained from a plurality of incinerators. A method and apparatus for removing mercury and an apparatus for treating exhaust gas containing mercury are provided. An ash dryer that heats incinerated ash containing mercury to 100 ° C. or more to volatilize mercury in dry exhaust gas, and a first exhaust gas treatment line that processes the exhaust gas containing volatilized Hg, A second exhaust gas treatment line for treating the exhaust gas of the ash melting furnace 13 for melting the ash containing Cl-based salt, and in the second exhaust gas treatment line, the Cl-based salt in the exhaust gas after the secondary combustion The first bag filter 16 that collects solid particles containing slag and the second bag filter 17 in which slaked lime and activated carbon are introduced are connected in series, and the first gas that treats the exhaust gas containing Hg The processing line is configured to merge between the first bug filter and the second bug filter.
