METHOD FOR THE PREPARATION OF BIOMASS FERTILIZER FROM LIQUID MANURE FROM AGRICULTURAL ANIMALS, SUCH AS CATTLE, PIG, SHEEP, CHICKENS AND THE LIKE

摘要

Multi-stage process for processing agricultural manure to produce biomass fertilizer, characterized by the following process steps: a) Separation of the agricultural manure mixture by mechanical separation such as sieving (gratings) or centrifugation of coarse foreign bodies such as straw, from the essentially liquid phase or homogenization of the manure mixture Shredding straw and hay fibers b) Adding C-containing substances such as mono - di, oligo. Polysaccharides, pyruvic acid and gluconodeltalactone and the like for the liquid phase or the homogenized liquid manure mixture, c) biogenic semi-aerobic fermentation for acidification by adding bacteria up to a pH of about 6.0-5.8 d) aerobic dissimilation and / or fermentation and further acidification up to a pH of about 4.8 with the addition of mold and / or yeast and / or bacteria with air or oxygen supply, the inorganic ions present in the essentially liquid phase of the slurry or in the homogenized slurry mixture, in particular ammonium ions, Potassium ions and phosphate ions are metabolized by the molds and / or yeasts and / or bacteria in a microbiological reaction and are organically bound or stored in the resulting organic nitrogen compounds, such as amino acids, oligopeptides, peptides, proteins, chitins, urea and phytin or other organic compounds ,
