The article deals with the technology of reagent treatment of biodegradable organic waste of livestock complexes for the production of organomineral fertilizers. The main regularities of the process of separation into liquid and solid fractions using oxalic acid are determined and analyzed; optimal doses of reagents; dependences of changes in the properties of the fraction at various stages of processing with calcium carbide sludge, comparing them with the indicators obtained using lime milk, superphosphate and phosphogypsum. An optimization model of the reagent process has been created to determine the best conditions for biogenic separation.
