The invention relates to a method for treating gaseous VOCs by a solid extraction-electro-catalytic oxidation method and a device thereof. The method has the steps that: firstly, an electromagnetic type air compressor is used for controlling the gas flowing velocity by a glass rotameter so as to ensure contaminations in the contamination solution in a gas washing bottle to be stripped into an electrochemical reactor; secondly, microporous aeration heads are distributed in the electrochemical reactor, after being stripped into the electrochemical reactor, the gas is distributed in the electrochemical reactor by the microporous aeration heads, takes parts in the electrochemical reaction and passes through the cathode of absorptive and conductive porous material and the anode of iron sheet in sequence; thirdly, the treated gas finally flows out from the top end of the electrochemical reactor and enters into the gas absorption solution.
