Mobile biogas plant for processing animal waste

The article analyzes the prospects for the development of new energy-saving technologies in agriculture, the problems of energy conservation and energy efficiency. The results of tests of the developed mobile biogas plant under thermophilic fermentation mode (55 ° C) of organic agricultural waste are presented. According to the experimental results, biogas was obtained with the composition: 67.8% CH4, 28% CO2, 3% H2, 1% N2, 0.1% H2O and traces of 0.003H2S. The analysis of the obtained high-quality organic fertilizer according to agrochemical, microbiological, sanitary-parasitological, sanitary-entomological and quality indicators was carried out in a certified laboratory of the Tatar Interregional Veterinary Laboratory. The fermentation time for the complete processing of organic waste was 16 days. During this time, biogas production amounted to: pig manure - 10 m3, chicken manure - 7 m3, horse manure - 5 m3, cattle manure - 8 m3. The nitrogen content after processing increased than in the non-processed substrate. The acidity values in the substrate are neutral - pH 7. The phosphorus content was 2.3%, potassium 1.3%. The resulting product is recommended for use on acidic soils.
