Abstract
The applicability of learned introduction of anaerobic digestion of animal waste will be obvious after a wide setting of afull-scale experiment and an across-the-board economic feasibility.However, yet today, basing on the domestic and abroad practice on biopowerdigesters engineering and operation,it can be argued that their use is economically advantageous than the traditional system. The obtained experience evidences thatthe cubicle housingof dairy cows is advanced. Milking operation is carried out in a special house, which ramps up milkquality, improves working conditions for milkmaids, and reduces labor costs.The problem of the animal waste impact on environment, especially on natural waters is acute. There is no summarized information about their distribution for fertilization and discharge.Not only liquid animal waste, but also silage sap causepollution. The Energy Program sets the task of widespread involvement of non-conventional energyin the country's energy balance. Biomass is of the great importance among such sources in the agro-industrial complex of the country.Anaerobicmethanoic digestion of animal waste allows evolving biogas – a valuable organic fertilizer with extra biological activityor protein-vitamin concentrates for feed supplementation.Such digestion of animal waste is an effective environmental action that provides its deodorization, reduction of soil and water pollution with repugnant substances and pathogenic microflora, atmospheric emissions (due to removal)
Highlights
A large amount of biomass energy in agriculture contributes to the continuous exploration and advanced technology development for its generation
After changing the full volume of the reactor, ithas been increased to 10% of the volume with automatic delivery of fractional portions 24 times a day.In general, the process of animal waste anaerobic digestion, controlled by temperature, biogas output, content of dry and organic substance in the charged and fermented biomass, pH, volatile fatty acids and other technical parameters, has been satisfactory.the productivity of the bioreactor for gas output fluctuated greatly
Tests indicate that the main animal waste digesting is in the reactor: the amount of suspended substances in the fermented mass has been reduced by 40%; in the holding tank – only by 4%
