APPROBATION OF A NEW BIOGAS TECHNOLOGY: EXPERIMENTS AND RESULTS

Abstract

There is currently a problem in the crop-growing branch of the republic – deficiency in mineral and qualitative organic fertilizers. This problem can be smoothed by means of production of the fertilizer out of the volume of liquid manure. That’s why development of technology for utilization of cattle liquid manure ensuring not only observance of environmental safety, but also contributing to creation of energy-saving closed production with generation of mineralized organic fertilizer which allows increasing crop capacity; feeding vitamin supplement; additional energy source in the form of biogas is a relevant objective of scientific and practical interest. There are various ways and methods for processing of cattle liquid manure. However, for natural climatic conditions of Yakutia anaerobic fermentation in biogas units (BU) is the most appropriate way. But the problem is what fermentation conditions and what equipment are able to ensure maximum efficiency of the process at minimum costs, and it requires special research. The researchers are conducted on the basis of general provisions of research and development performance. The authors used theories of similitude and experimental design, methods of mathematical programming and imitational modelinge.
