The utility model discloses an aerobic composting device capable of recycling ammonia gas. The device comprises an aerobic composting bin, an ammonia gas absorption tank, a nitrogen fertilizer manufacturing box and a leachate collecting tank. The aerobic composting bin is sequentially provided with a water vapor condensation area, a composting stirring area and a leachate collecting area from top to bottom. The top of the aerobic composting bin is an inclined plane and can condense water vapor generated in the composting process; the ammonia gas absorption tank is used as a place for ammonia gas absorption and reaction of ammonia gas and carbon dioxide; the nitrogenous fertilizer manufacturing box can be heated, carbon dioxide can be provided for nitrogenous fertilizer manufacturing, and ammonium bicarbonate particles are obtained. The compost stirring area is used for stirring and supplying oxygen; the bottom of the aerobic composting bin is divided into a percolate collecting area by percolate gauze and a g
