Exhaust gas treatment apparatus

Provided is an exhaust gas treatment apparatus that is capable of efficiently removing toxic gases contained in exhaust gas without increasing the size of apparatus. An exhaust gas treatment apparatus (100) includes: a main body (1) formed with a flow channel (1a) for liquid to flow therethrough; an exhaust gas supply line (2) connected to the main body (1) and supplying exhaust gas to the flow channel (1a) for liquid to flow therethrough; a suction device (3) sucking exhaust gas from the exhaust gas supply line (2) to the flow channel (1a); a low-temperature plasma generator (5) generating low-temperature plasma in the flow channel (1a) to decompose harmful gas; and an exhaust line (7) for exhausting exhaust gas that has passed through the low-temperature plasma generator (5) from the main body (1).
