LBR-anaerobic filter two-phase anaerobic digestion reactor

The invention discloses an LBR-anaerobic filter two-phase anaerobic digestion reactor, which comprises a feeder, an LBR reactor and an anaerobic filter reactor, a two-phase separation anaerobic digestion process is realized in the reactor, solid-liquid separation can be carried out while anaerobic digestion is carried out, and resource reutilization and solid waste treatment are facilitated; a hydrolytic acidification reaction and a methanogenesis reaction are separated, so that the reaction effect is remarkably improved, and the gas production quality is improved; the up-down flow type spiral stirrer is combined with the conveying device, so that the materials with higher solid content are in a circulating stirring and mixing state, and the hydrolysis is accelerated; the LBR reactor can regulate and control the retention time of material solids, and the anaerobic filter tank can prolong the hydraulic retention time of leachate to increase the gas production rate and the microbial biomass; the spiral stirrer
