摘要： The present disclosure provides a method for two-phase partitioning production of a medium-chain fatty acid (MCFA) by dry anaerobic digestion. In the present disclosure, due to a slow heat transfer of the dry anaerobic digestion, a same dry anaerobic digestion device is naturally divided into two phases, and the MCFA is synthesized while producing electron acceptors and electron donors in the same dry anaerobic digestion device. Meanwhile, the dry anaerobic digestion device is provided with a high-efficiency decomposing microbial inoculant on an upper part and inoculated with sludge having a carbon chain extension function on a lower part. In this way, a material residence time is regulated, and cycles of hydrolytic acidification and carbon chain extension are shortened, thereby achieving the high-value conversion of agricultural waste while increasing a conversion rate of organic acids in the dry anaerobic digestion.
