DESIGNING A TECHNOLOGICAL SCHEME FOR THE DISPOSAL OF LIVESTOCK WASTE

Abstract

The article considers the issue of developing a technological model for processing livestock waste. An analysis of the problem of animal waste management has shown that raw manure waste without processing has a negative impact on the environment, causing soil poisoning, polluting the air, groundwater and is a source of infectious diseases. Ammonia is one of the most common pollutants emanating from livestock farms. This gas forms during the decomposition of organic residues such as manure and urine released by animals. It tends to accumulate in the lower layers of the atmosphere, posing threats to both ecosystems and human health. Analysis of the composition of animal husbandry waste has shown that animal waste is a valuable source of organic and mineral substances and, with appropriate processing, valuable products such as fertilizers and additional energy such as biogas can be obtained from them. A scheme of a technological complex consisting of four modules is proposed for waste recycling. It is also planned to introduce a module for obtaining high-quality fertilizers through the enrichment of sludge formed during methanogenesis, followed by granulation. Based on a comparative analysis of existing methods and technologies, an optimal technological scheme for the production of biogas and organo-mineral fertilizers in livestock complexes has been developed and proposed.
