    Abstract: It is intended to provide an exhaust gas treatment system, which allows for VOC removal at lower temperatures and thereby improves the durability of catalysts and suppresses carbon monoxide generation at the final outlet of the system. The present invention provides a treatment system of an exhaust gas containing a nitrogen oxide, carbon monoxide, and a volatile organic compound comprising: an exhaust gas treatment means for removing the nitrogen oxide by reduction with ammonia and partially oxidizing the VOC to CO; and a CO/VOC removal means for oxidizing the CO and partially unreacted VOC, in this order from the upstream flow of the exhaust gas.

    Abstract: An apparatus for treating a combustion exhaust gas is here provided which comprises a fire furnace, a denitrating reactor for denitrating the combustion exhaust gas discharged from the fire furnace, a dust collector for collecting solids in the exhaust gas passed through the reactor, and a transport pipe for circulating the solids collected by the dust collector through the fire furnace, the apparatus being characterized in that the transport pipe is provided with an arsenic removal means for removing arsenic from the solids. The arsenic removal means may be a heating device or a washing device. The dust collector may be provided with a means for discarding the solids having a particle diameter of 10 .mu.m or less.
