The invention provides an internal-mixing anaerobic reaction tank. A tank body is of a column shape, and a cone-shaped sludge bulking region, a reaction region, a gas-solid-liquid separation region and a precipitation separation effluent region are sequentially arranged in the tank body from bottom to top; and the cone-shaped sludge bulking region is a cone-shaped cover, an effluent weir is arranged above the precipitation separation effluent region, an automatic return-flow system is arranged at the top of the tank body and comprises an air lifting pipe, an air-water separation tank and a return pipe, the air lifting pipe is connected with the cone-shaped sludge bulking region and the air-water separation tank, the return pipe stretches into the lower part of the reaction region, a sewage gas pipe is connected between the air-water separation tank and the gas-solid-liquid separation region, and a sewage gas circulating pipe is connected between the air-water separation tank and a water distribution pipe. The internal-mixing anaerobic reaction tank has the advantages that the tank body is low in height, the tank can be started quickly by flocculent sludge with high shock load resistance, the requirement on a Ph value of inflow water is low, granule sludge increases quickly, the processing energy consumption is low, the processing efficiency is high, the effluent quality is stable, and the tank is suitable for processing of organic pollutants in various concentrations, simple to operate and convenience to run.
