    • PROBLEM TO BE SOLVED: To provide a biogas treatment method and apparatus that have low cost and superior treatment efficiency.SOLUTION: In a biogas treatment method, a gas to be treated and a circulation liquid containing oxidative decomposition component to be treated are introduced into a gas-liquid contact column 1, which is equipped with a gas-liquid contact part having an electrically conductive microorganism carrier carrying microorganism, and are brought into gas-liquid contact in the gas-liquid contact part, wherein the oxidative decomposition component to be treated is subjected to oxidative decomposition by the microorganism. In the method, the oxidative decomposition of the oxidative decomposition component to be treated is performed in a condition, in which a positive electrode voltage is applied to the electrically conductive microorganism carrier composed of high temperature firing carbon wherein a ratio (P1/P2) of 1,580 cmpeak intensity (P1) and 1,360 cmpeak intensity (P2) in Raman spectrum is ≥0.85. The invention also includes a biogas treatment apparatus that performs the method.
    • 要解决的问题:提供一种成本低廉,处理效率优良的沼气处理方法和装置。解决方案:在沼气处理方法中,将待处理气体和含有待处理的氧化分解成分的循环液引入 气液接触柱1,其配备有具有携带微生物的导电微生物载体的气液接触部,并且在气液接触部中进行气液接触,其中待处理的氧化分解成分 被微生物氧化分解。 在该方法中,在对由高温烧成碳构成的导电性微生物载体施加正极电压的条件下进行待处理的氧化分解成分的氧化分解,其中,比例(P1 / P2)为 拉曼光谱中的1,580 cmpeak强度(P1)和1360 cmpeak强度(P2)≥0.85。 本发明还包括执行该方法的沼气处理装置。
