Abstract

The utility model discloses a column-type anaerobic-aerobic integrated fermentation device, relating to environmental protection and energy techniques. The reaction tank of the device comprises a tank body, a heat preserving layer and a top cover. A gas storage bag, an air compressor and an electric heating machine are sequentially connected outside the tank. Marsh gas is filled in the gas storage bag. At the initial stage of anaerobic fermentation, the air compressor fills the marsh gas into the tank body through a pipe to form an anaerobic environment; simultaneously, the electric heating machine heats the filled marsh gas to heat materials in the tank body, the heat preserving layer preserves heat, and therefore the problems that the anaerobic fermentation is difficult to be started and process temperature is difficult to be controlled under low-temperature conditions can be solved; and after the anaerobic fermentation is competed, air is pumped into the tank body through the pipe to conduct aerobic composting fermentation to biogas residues. Since the biogas residues are integrally treated and organic fertilizers prepared by using the biogas residues can be directly taken out for use after the integrated treatment is completed, the marsh gas and/or the organic fertilizers can be produced continuously and stably by a fertilization system.
