FIELD: chemistry.
SUBSTANCE: inventions relate to production of fertiliser based on organic substances. Method of obtaining fertiliser, based on organic substances, includes the following stages: (a) accumulation of wastes of animal breeding in shed (b) fast separation of wastes of animal breeding into liquid wastes and solid wastes on conveyor belt in shed, (c) clarification of liquid wastes and obtaining in this way supernatant and sludge, (d) extraction of ammonia from supernatant with obtaining ammonium salt and water solution, (e) filtration of water solution with obtaining concentrate and usable water, (f) application of ammonium salt, concentrate and sludge as additive to solid wastes, (g) shaping solid wastes as fertiliser based on organic substances. Method of obtaining fertiliser, based on organic substances, includes the following stages: (a) accumulation of liquid manure from wastes of animal breeding, (b) separation of liquid into filtration sediment and filtrate by pressing, (c) clarification of filtrate with obtaining supernatant and sludge, (d) separation of sludge by pressing with obtaining second filtration sediment, (e) extraction of ammonia from supernatant with obtaining ammonium salt and water solution, (f0 filtration of water solution with obtaining concentrate and usable water, (g) application of ammonium salt and concentrate as additive to first filtration sediment and second filtration sediment and (h) shaping first and second filtration sediments as fertiliser based on organic substances.
EFFECT: inventions make it possible to provide improved system and method of producing fertliliser, based on organic substances.
