Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To trap and decompose harmful substances (e.g. NOx, SPM, or the like) in ventilated gas, make no need of new further treatment works, and highly efficiently and reliably clean the gas without affecting environments. SOLUTION: The apparatus for cleaning NOxand SPM comprises a discharge part 11 installed in a gas discharge channel 2 of a ventilated gas containing coexisting oxygen for carrying out discharge treatment to the ventilated gas led to and an adsorption part 12 for adsorbing and removing constituent components of NOx(nitrogen oxides) to be oxidized and decomposed by the discharge treatment, wherein the discharge part 11 has the function of producing NO2(nitrogen dioxide) by oxidizing NOxcontained in the ventilated gas by discharge treatment of the ventilated gas led to and the function of trapping SPM (suspended particle matter) contained in the ventilated gas by charged particles and electric field generated by the discharge treatment and burning and decomposing the trapped substances.
