The article deals with the issue of disposal of bedless manure. As a result of the analysis, a promising technological line for the processing and disposal of bedless manure was selected for research, including as the main equipment: a device for separating the initial mass of liquid manure into solid and liquid fractions, primary sedimentation tanks and bactericidal batteries. The electroflotation unit was chosen as the main unit for further research. In this case, electrolysis of polluted water occurs under the action of direct current. Studies have established that manure runoff with a moisture content of more than 92% practically does not stratify. However, the situation with the separation of wastewater into fractions changes radically after treatment in an electromagnetic field. The use of the proposed scheme of the technological line will make it possible to obtain valuable organic fertilizer and improve the ecological situation at livestock enterprises. The main of many factors that characterize the quality of separation of bedless manure into fractions is the degree of purification of its liquid fraction. The separated water is a dispersed medium and is several times larger than the solid fraction of bedless manure by volume. Analyzing the dependences obtained, it can be concluded that with an increase in the height of the treated wastewater layer, a decrease in purification occurs, and the regularity has the form of a hyperbolic curve.
