The equipment and technology for producing organic fertilizer using biogas residue and pig manure fermentation are as follows: 1. The equipment required for the production of organic fertilizer from livestock and poultry manure includes a mixer and an electric sieve. Screening Machine 2. Raw Materials (Taking the production of 1 ton of organic fertilizer as an example): requires 1.8 tons of human manure or livestock manure, 0.3 tons of straw powder or leaf powder, 2.5 kilograms of corn flour, and 1 kilogram of rapid fermentation bacterial agent.

3. The production process of organic fertilizer from feces: human excrement and urine, animal manure+leaves or straw powder+corn flour+bacterial strains → mixing → composting → drying → packaging → leaving the factory.

4. First, control the moisture content of the mixed fecal organic fertilizer raw materials at around 40% -50%. Then, mix the bacterial strains with jade water surface and sprinkle them on the surface of the mixed fertilizer. Manually and evenly load the raw materials into the mixer for crushing and stirring. When mixing and crushing fertilizers, the moisture content should be controlled, generally not exceeding 40% -45%. Excessive or insufficient moisture can affect the quality of fermentation. It is advisable to pinch the fertilizer with your hands to form a dough, and if water is visible but not dripping, it should be released and dropped to the ground. Stir evenly, thoroughly, and fluffy without leaving any lumps.

5. Mix the organic fertilizer ingredients in a pile or a long strip with a width of 1.5-2 meters and a height of 0.3-0.4 meters, and cover it with a straw curtain or burlap bag for aerobic fermentation. Generally, the temperature rises to 50 ° C within 24 hours of stacking, and can reach 60-70 ° C within 48 hours. During fermentation, such high temperatures can remove all pathogenic bacteria, insect eggs, grass seeds, etc.

6. According to the experiment of organic fertilizer production from feces, it generally takes 6 days to compost and make fertilizer in spring, summer, and autumn, and 7 days in winter. When the fertilizer is covered with white mycelium on both sides, it is fully decomposed, and then dried and sieved slightly. The production method of fecal organic fertilizer is now completed.
