NOVELTY - Setting organic fertilizer production workshop, comprises (i) selecting a field to set a raw material pretreating workshop; (ii) setting a fermentation workshop connected with the material pretreating workshop, setting a fermentation tank in the fermentation workshop, setting a waste gas processing device at the top of the fermentation workshop provided with a biological deodorization tank connected with a waste gas treatment device; (iii) setting a decomposition workshop connected with the fermentation workshop; and (iv) setting a production packing workshop below the decomposition workshop.    USE - The production workshop is useful for producing the organic fertilizer.    ADVANTAGE - The production workshop: is convenient to operate; has low processing cost; processes the livestock and poultry manure in batches; and prevents secondary pollution; and the method improves the utilization of the livestock and poultry manure; and produces the organic fertilizer, which is convenient to store and transport.    DETAILED DESCRIPTION - Setting organic fertilizer production workshop, comprises (i) selecting a field to set a raw material pretreating workshop; (ii) setting a fermentation workshop connected with the raw material pretreating workshop at a gap slope surface far away from the bottom of the raw material pretreating workshop by 2-5 m, setting a fermentation tank in the fermentation workshop, setting a waste gas processing device at the top of the fermentation workshop provided with a biological deodorization tank connected with a waste gas treatment device through a pipe; (iii) setting a decomposition workshop connected with the fermentation workshop at the gap slope surface far away from the bottom of the fermentation workshop by 4-6 m below the fermentation workshop; and (iv) setting a production packing workshop below the decomposition workshop at the gap slope surface far away from the bottom of the decomposition workshop, where the production packing workshop is provided with a packing production line including a pelletizing machine, a dryer and an automatic packing machine which are connected in order. An INDEPENDENT CLAIM is also included for producing an organic fertilizer, where the organic fertilizer is produced in the production workshop, comprising (a) adding livestock and poultry manure and adjuvants with moisture content of 50-60% into the raw material pretreatment workshop according to the carbon and nitrogen ratio of 20-30, adding strains (1-2 kg) into every 100 tons of raw materials, and mixing the raw materials; (b) entering the mixed raw materials into the fermentation workshop, utilizing the gap slope surface between the raw material pretreating workshop and fermentation workshop to mix the raw materials, and piling the raw materials on the ground in the fermentation workshop for 1-2 days, and transferring to the fermentation tank, and grinding the raw materials in the fermentation tank to ferment, overturning the raw materials by a turning machine, feeding the bad odor produced in the process into the biological deodorization tank to deodorize by the waste gas treatment device through the pipe; (c) removing the raw materials from the fermentation tank after fermentation, entering into the decomposition workshop to pile, removing the piles for every 7-10 days, finishing piling after removing the piles for 2-3 times, and decomposing; (d) transferring the fermented and decomposed fertilizer into the production packing workshop and screening the impurities in the raw materials through a screen mesh; and (e) pelletizing by the pelletizing machine, drying until the moisture content reaches below 30% with the dryer, and finally packing with the automatic packing machine.
