Abstract. The intensification and mechanization of pig farms contributed to an increase in livestock and production, and at the same time, the rapid accumulation of manure. A large amount of animal waste in complexes with intensive production technologies, the conversion capacity of soils and water predominates, increasing environmental pressure on the environment. Existing processing and disinfection technologies cannot fully fulfill their functions, since they are expensive and, in some cases, can have a negative effect on the soil. Negative trends in environmental degradation by inefficient treatment of effluents, prompts the search for new promising treatment methods. The expansion of the range of applications of electrical technologies in agricultural production is attracting increasing attention to electrical pulse processing, the principle of which is based on the so-called Yutkin effect. This processing method was previously used in mining and metal processing, now it has become promising to apply electric pulse processing to affect organic substances. The article discusses the important issues of the operation of a laboratory installation for electropulse treatment of wastewater from livestock complexes. Since the installation is high-voltage, it is important to choose the necessary operating parameters correctly, the sewage treatment process is accompanied by a local increase in pressure in the working chamber, and the so-called cavitation process. The cavitation process, in turn, plays an important role in the disinfection of waste, since essentially liquid effluents contain protein, and during electropulse processing, protein denaturation (cleavage) occurs, which makes it impossible to develop pathogenic microorganisms and neutralizes existing helminths. An important issue is the selection of the optimal parameters of the experimental laboratory setup for safe operation and removal of data measurements. Using the provisions of the theory of the foundations of electrical engineering, the main parameters of work are selected, the process that occurs during the treatment of drains is theoretically investigated.
Key words: waste treatment, electric pulse processing
