摘要
生物电化学系统中,对抑制产甲烷作用的研究是在微生物电解池(MEC)厌氧消化产氢中非常重要的一环。依据目前的研究结果,主要采用定期曝气、缩短HRT、加入甲烷抑制剂、控制温度、调节SRT、控制氧化还原电位等方法来抑制产甲烷菌的活性。其中,低温,调节SRT和氧化还原电位对于需要长时间运行的MEC反应器而言,是相对较好的方法。
In bioelectrochemical system, inhibiting methanogenesis was very important part for hydrogen production in the microbial electrolysis cell. Based on these findings, timed aeration,methane inhibitor, temperature, sludge retention time, hydraulic retention time and oxidationreduction potential were used to inhibitmethanogenesis. Among them, controlling low temperature, sludge retention time and oxidation-reduction potential were better for the longtime running microbial electrolysis cell.
