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.

本发明涉及一种固态萃取-电催化氧化法处理气态VOCs的方法及装置，方法步骤：第一步，电磁式空压机通过玻璃转子流量计控制气体流速，将气体洗瓶中的污染物溶液中的污染物吹脱进电化学反应器；第二步：电化学反应器中布有微孔曝气头，气体吹脱进入电化学反应器后，通过微孔曝气头分布于电化学反应器内，参加电化学反应，依次经过通过吸附性导电多孔材料阴极和Fe片阳极；第三步，经处理后的气体最后从电化学反应器顶端流出进入气体吸收溶液。
