However, the existing catalytic combustion device usually adopts a noble metal catalyst, the catalyst can well decompose organic matters into water and carbon dioxide, but when organic waste gas contains nitrogen-containing organic matters, a large amount of nitrogen oxides can be generated, the emission of the nitrogen oxides exceeds the standard, and a denitration device is required to be additionally arranged to remove the nitrogen oxides, so that the emission reaching the standard can be realized. Therefore, the conventional catalytic combustion device is only suitable for treating organic matters only containing carbon and hydrogen elements, and can not treat nitrogen-containing organic matters, so that the application of the conventional catalytic combustion device is limited.

The oxidizer oxidizes NO in the exhaust gas to NO2And the absorption liquid in the absorption tower is NaOH solution. In this way, the emission of nitrogen oxides at the outlet is reduced. Chinese patent application CN2018101019342 discloses an N, N-Dimethylformamide (DMF) exhaust gas treatment system, which is implemented by washing twice to reduce the concentration of DMF in the exhaust gas to a trace amount, and then passing through a regenerative oxidation furnace.
