The present invention relates to a composting apparatus for producing organic fertilizer by mixed fermentation of livestock manure, by-product of agricultural and marine products, or food waste. More specifically, the present invention relates to a composting apparatus for producing organic fertilizer by mixed fermentation of livestock manure, by-product of agricultural and marine products, or food waste, which makes it possible to ferment and produce compost, which is organic fertilizer, quickly and efficiently by mixing and fermenting at least one raw material of livestock manure, by-product of agricultural and marine products, and food waste. The composting apparatus also maintains a constant fermentation temperature in a mixture within a fermentation tank which is closed with a double structure so that odor during fermentation does not leak. The present invention comprises an inlet for introducing the raw material, an outlet for discharging the organic fertilizer, an air supply port for introducing air, etc.
