NOVELTY - Continuous and high-efficient production of fertilizer using animal manure comprises passing the animal manure into a primary storage tank with raw water; removing the primary contaminants in the stored raw water, carrying out solid-liquid separation of the sludge and supernatant; passing sludge into primary fermentation tank, carrying out primary fermentation; introducing the compost obtained into a secondary fermentation tank, and carrying out secondary fermentation; and crushing the secondary fermented compost.    USE - The method is useful for continuous and high-efficient production of fertilizer using animal manure (claimed).    ADVANTAGE - The method is simple and manageable, reduces the fertilizer production cost, is economical, and produces fertilizer with stable effect and high quality, and minimizes the generation of odor.    DETAILED DESCRIPTION - Continuous and high-efficient production of fertilizer using animal manure, comprises passing the animal manure via a screen to remove contaminants, and then introducing into a primary storage tank with raw water; removing the primary contamination in the stored raw water, and passing the raw water into solid-liquid separator for solid-liquid separation of the sludge and supernatant; regulating the water content in the separated sludge by using water control agent, and mixing in a mixer, then stirring and passing into primary fermentation tank, for carrying out primary fermentation; introducing the compost obtained by primary fermentation into a secondary fermentation tank under stirring condition, and carrying out secondary fermentation; crushing the secondary fermented compost, and screening the crushed compost to remove impurities; adding the separated supernatant into an aeration tank, and carrying out aeration; introducing the aerated supernatant into multi-stage aeration tank, and carrying out secondary stage aeration; transferring the secondary stage aerated supernatant into multi-stage liquid manure storage tank, and storing the manure; and adding the liquid manure into a separating tank, and removing non-biodegradable materials. An INDEPENDENT CLAIM is also included for a device for continuous and high-efficient production of fertilizer using the animal manure, comprising screen for removing contaminants from animal manure; primary storage tank for storing raw water and the animal manure; solid-liquid separator for solid-liquid separation of the sludge and supernatant; a sludge composting device for composting the sludge; a sludge storage hopper for storing the sludge of solid-liquid separator and composting device; mixer for mixing the separated sludge and a water control agent; a primary fermentation tank for carrying out primary fermentation of compost manure; a secondary fermentation tank for carrying out secondary fermentation of obtained compost; a separator for screening the crushed compost to remove impurities; an aeration tank for carrying out aeration of separated supernatant by supplying oxygen; multi-stage aeration tank for carrying out secondary stage aeration of aerated supernatant and; multi-stage liquid manure storage tank for storing secondary stage aerated supernatant and the manure; and a separating tank for removing non-biodegradable materials from liquid manure.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the process flow for producing fertilizer (Drawing includes non-English text).
