The utility model relates to the technical field of sewage treatment, and particularly discloses a high-speed upwelling circulating sludge bulking anaerobic reactor which is characterized in that a tank main body sequentially comprises a mixed reaction area, a biological filler reaction area, a three-phase separation area and a sludge-water separation area from bottom to top; the water inlet pipe enters the tank main body from the mixed reaction area, and the water outlet pipe leaves the tank main body from the mud-water separation area; the mud-water separation area is formed by hiding a closed funnel-shaped water tank in the tank main body, a return pipe is arranged at the bottom of the funnel-shaped water tank, and the return pipe and the water inlet pipe are convectively converged in the mixed reaction area. According to the improvement, the anaerobic sludge can be kept in an expansion state, the contact between sewage organic matters and the anaerobic sludge is enhanced, the mass transfer effect is enhan
