Abstract
Predmetni izum se odnosi na postupak i sustav za tretiranje i recikliranje digestata dobivenog anaerobnom digestijom ulazne biomase, odnosno gnoja, gnojovke, biljnih materijala i energetskih usjeva u kogeneracijskom bioplinskom postrojenju. Postupak tretiranja i recikliranja digestata i dobivanja smjese gnojiva iz organskih supstrata digestata dobivenog anaerobnom digestijom biomase u AD digestoru (10) u mezofilnim uvjetima gdje je digestat produkt ciklusa proizvodnje bioplina u kogeneracijskom bioplinskom postrojenju obuhvaća kristalizaciju smjese gnojiva u reaktoru (1) doziranjem magnezijeve soli, kalijeve soli i amonijeve lužine uz konstantno miješanje i mjerenje temperature i pH vrijednosti; separaciju krute frakcije (13;5) od tekuće frakcije (6) u separatom (4); kemijski tretman krute frakcije (5) u reaktoru (2) u kiselinskoj vodenoj otopini uz konstantno mjerenje temperature T i pH vrijednosti; sušenje kiselinom tretirane krute frakcije (5) u sušioniku (7) nakon čega se dobivena tretirana suha tvar dovodi u AD digestor (10) u kojem se miješa s ulaznom biomasom; i anaerobnu digestiju mješavine tretirane suhe tvari i ulazne biomase u AD digestoru (10) u mezofilnim uvjetima.The related invention refers to a process and system for treating and recycling of digestate obtained by anaerobic digestion of input biomass, i.e. manure, slurry, plant material and energy crops in a cogeneration biogas plant. The method of treating and recycling digestate and obtaining a fertilizer mixture from organic substrate of digestate obtained in anaerobic digestion of biomass in an AD digester (10) under mesophilic conditions where digestate is the product of biogas production cycle in a cogeneration biogas plant comprises crystallization of the fertilizer mixture in a reactor (1) by dosing magnesium salt, potassium salt and ammonium hydroxide with constant stirring and temperature and pH value measurement; separation of the solid fraction (13;5) from the liquid fraction (6) in a separator (4); chemical treatment of solid fraction (5) in a reactor (2) in acidic aqueous solution with constant temperature T and pH value measurement; drying the acid-treated solid fraction (5) in a drier (7), whereupon the resulting treated dry substance is introduced into an AD digester (10) in which it is mixed with the input biomass; and anaerobic digestion of the treated dry matter mixture and the input biomass in the AD digester (10) under mesophilic conditions.The present invention relates to a process and system for the treatment and recycling of digestates obtained by anaerobic digestion of input biomass, ie manure, slurry, plant materials and energy crops in a cogeneration biogas plant. A process for treating and recycling digestates and obtaining a fertilizer mixture from digestate organic substrates obtained by anaerobic digestion of biomass in an AD digester (10) under mesophilic conditions where the digestate is the product of a biogas production cycle in a cogeneration biogas plant comprising crystallization of the fertilizer mixture in a reactor (1) by magnesium dosing potassium salts and ammonium alkali with constant mixing and measurement of temperature and pH; separating the solid fraction (13; 5) from the liquid fraction (6) in the separator (4); chemical treatment of the solid fraction (5) in the reactor (2) in acidic aqueous solution with constant measurement of temperature T and pH; drying the acid-treated solid fraction (5) in the dryer (7) after which the resulting treated dry matter is fed to an AD digester (10) in which it is mixed with the incoming biomass; and anaerobic digestion of a mixture of treated dry matter and input biomass in an AD digester (10) under mesophilic conditions.The related invention relates to a process and system for the treatment and recycling of digestate obtained by anaerobic digestion of biomass input, i.e. manure, slurry, plant material and energy crops in a biogas plant cogeneration. The method of treating and recycling digestate and obtaining a fertilizer mixture from an organic substrate of digestate obtained in anaerobic digestion of biomass in an AD digester (10) under mesophilic conditions where digestate is the product of biogas production cycle in a cogeneration biogas plant comprising crystallization of the fertilizer mixture in a reactor (1) by dosing magnesium salt, potassium salt and ammonium hydroxide with constant stirring and temperature and pH value measurement; separation of the solid fraction (13; 5) from the liquid fraction (6) in a separator (4); chemical treatment of solid fraction (5) in a reactor (2) in acidic liquid solution with constant temperature T and pH value measurement; drying the acid-treated solid fraction (5) in a drier (7), whereupon the resulting treated dry matter is introduced into an AD digester (10) in which it is mixed with the biomass input; and anaerobic digestion of the treated dry matter mixture and the biomass input in the AD digester (10) under mesophilic conditions.
