摘　　要：针对现有生物甲烷过程存在发酵速率低,副产物沼液和沼渣难以处理的问题,在对沼渣原料进行元素等分析基础上,用磷酸法活化沼渣获得活性炭,通过Raman、化学吸附仪、SEM和亚甲基蓝吸附分别对产物类型、孔结构、形貌和吸附值进行表征。结果表明,成功制备出比表面积为1 297 m^2/g,亚甲基蓝吸附值为476 mg/g的活性炭,为生物甲烷系统过程内部循环提供基础。To solve the existing problems in biogenic methane process such as low fermentation speed and difficulties in treating with by-products biogas slurry and residue,activated carbon is made through the activation of biogas residue by phosphoric acid method based on elements analysis upon biogas residue and so on. The type,pore structure,morphology and adsorption value of the prepared activated carbon are characterized by Raman,chemical adsorption instrument,SEM and methylene blue adsorption respectively. The results show that the prepared activated carbon has a specific surface area of 1 297 m2·g-1 and its adsorption value against methylene blue is 476 mg·g-1,which provides a basis for the internal circulation of the biogenic methane production system.
