This application discloses a trough fermentation system for lignite fermentation, including a fermentation trough and a heating device for heating the fermentation trough. A floor heating coil is installed at the bottom of the fermentation trough. The heating device supplies heat to the fermentation trough through the floor heating coil, providing different amounts of heat to the fermentation trough in the early, middle, and late stages of fermentation, respectively, so that the fermentation trough is in the first, second, and third stages. The gradient temperature control of this application can accurately meet the temperature requirements of different stages in the fermentation process, significantly improving fermentation efficiency, accelerating the fermentation process, significantly shortening the fermentation cycle, and reducing greenhouse gas emissions, thus offering environmental advantages.
