The application discloses a novel biogas slurry membrane filtration device based on silicon carbide membranes, comprising: a silicon carbide membrane assembly, which is composed of four groups of membrane groups in parallel connection, and two ends of each group of membrane groups are connected with a shunt pipe and a collection pipe; each group of membrane groups comprises four silicon carbide tubular membrane tubes, and the four silicon carbide tubular membrane tubes are connected in series, each silicon carbide tubular membrane tube is provided with a plurality of large through-hole structures along the axial direction thereof, the diameter of the large through-hole structure is 8 mm, and the pore size of the membrane tube is 150 nm; and a cleaning assembly connected with the silicon carbide membrane assembly and used for cleaning the silicon carbide membrane assembly according to a preset mode. The application has stronger anti-clogging performance, is suitable for anaerobic biogas slurry treatment with high solid content and more organic fiber components, effectively alleviates the problems of scaling and fiber winding and clogging, and solves the problem of membrane strength through the thickening design of the membrane tube spacing.
