Enhanced straw fermentation process based on microbial electrolysis cell coupled anaerobic digestion
文献摘要：
The low quality and yield of methane severely hinder the industrial application of straw biogas fermen-tation,and no effective solution has been found so far.In this study,a novel method was developed when a microbial electrolysis cell(MEC)was coupled with normal anaerobic fermentation to enhance methane yield and purity.The fermentation process achieved a methane purity of more than 85％,which is consid-erably higher than that of previously published reports.With microbial stimulation and an electric cur-rent,the degradation of fibers has been greatly enhanced.The MEC system substantially improved the yield and purity of biogas,bringing a new path to the synthesis of methane by carbon dioxide and hydro-gen ions in solution under electron irradiation.Electrochemical index analysis showed extra methane synthesis,due to the external circuit electron transfer.The results of the gas chromatography and solid degradation rate showed that the carbon source of extra methane was CO2 produced during normal fer-mentation and additional volatile solid degradation.These results show that the MEC considerably enhanced the quality and yield of methane in the straw fermentation process,providing insights into nor-mal anaerobic fermentation.
