Production of Biogas using method of agricultural waste fermentation
Abstract
During using biogas as fuel for diesel engines, it is necessary to clean it from hydrogen sulfide, water and carbon dioxide, as well as to compressing it to fill cylinders more efficiently. Today the production of biogas in agriculture is the disposal of crop waste and manure from livestock farms.This approach is very actual, at the first stage of its implementation was planned to create the necessary material and technical base to widespread using of non-traditional energy sources, including organic biomass energy (fertilizer, crop waste, etc.). In addition, environmental protection, which also requires intensive and rational processing of animal waste, is very closely connected with the problem of waste disposal. This necessitates the search for processing methods that would ensure the comprehensive utilization of its agricultural, energy, feed and other properties. This article presents the technology for processing the utilization of manure using microbial synthesis. When processing manure in anaerobic conditions, the threshold lowered for its smell, germination of weed seeds, helminths die, and nutrients (nitrogen, phosphorus, and potassium) are completely preserved. The resulting biological gas contains up to 70 % methane, and its calorific value is 24 MJ/M3. The introduction of low-waste, resource-saving technologies with mechanization and automation of production processes plays an important role in the environment protection issues from livestock complexes waste in their further development. At present, there are several directions of processing of agricultural and water waste. At the same time, processing of animal waste with the use of biogas plants gives a significant socio-economic effect, expressed in improving working conditions, increasing the production culture and land use. Moreover, the environment protection rask is being solved.
