description The invention relates to biotechnology, particularly to a process for anaerobic production of biogas from agro-industrial waste.The process, according to the invention, provides for the pre-treatment of biomass by bringing it to a moisture of 80...90%, subsequent grinding of substrate with introduction of an organic biocatalyst, anaerobic fermentation in mesophilic regimen and collection of biogas, at the same time as biomass is used a mixture of alcohol distillery waste, cattle manure, hen's droppings and dispersed meat-processing production waste with the solid phase particle size of 20...100 µm in the weight ratio of 1: (0.2...0.7) : (0.1...0.2), respectively, as organic biocatalyst is used a 50...70% suspension of chestnut seeds of the Aesculus hippocastanum genus, obtained by crushing and wet milling to the dispersion of 0.1...1.0 µm, mixed with alcohol distillery waste as a liquid phase, which is dispensedly injected in the amount of 0.15...0.40 ml/L into the biomass under anaerobic fermentation, at a pH of 6.5...8.5 and periodic mixing.The result consists in the simultaneous increase of methane content in biogas and its caloric value. Invenţia se referă la biotehnologie, şi anume la un procedeu de obţinere anaerobă a biogazului din deşeuri agroindustriale.Procedeul, conform invenţiei, prevede tratarea prealabilă a biomasei prin aducerea acesteia la umiditatea de 80...90%, fărâmiţarea ulterioară a substratului cu introducerea unui biocatalizator organic, fermentarea anaerobă în regim mezofil şi colectarea biogazului, totodată în calitate de biomasă se utilizează un amestec din borhot de la distilarea alcoolului, dejecţii de bovine şi/sau de găini, şi reziduuri dispersate de la prelucrarea cărnii cu mărimea particulelor solide de 20...100 µm în raport de masă 1 : (0,2...0,7) : (0,1...0,2), respectiv, în calitate de biocatalizator organic se utilizează suspensie de 50...70% din seminţe de castan Aesculus hippocastanum, obţinută prin zdrobirea şi măcinarea umedă până la dispersivitatea de 0,1...1,0 µm, amestecată cu borhot de la distilarea alcoolului în calitate de fază lichidă, care se injectează dozat în cantitate de 0,15...0,40 ml/L în biomasă la fermentarea anaerobă la un pH de 6,5...8,5 şi amestecare periodică.Rezultatul constă în creşterea simultană a conţinutului de metan în biogaz şi valorii lui calorice. Изобретение относится к биотехнологии, а именно к способу анаэробного получения биогаза из агропромышленных отходов.Способ, согласно изобретен
