High standards of sanitary and epidemiological safety at large pig-feeding complexes are one of the prerequisites for the production of high-quality pork. Livestock complexes are a source of accumulation of a large amount of manure runoff. Now there is a large tendency of environmental destruction and irreversible loss of natural resources due to pollution by waste from livestock enterprises. The use of new technologies for treating wastewater from food enterprises, industrial, livestock breeding is an urgent problem. The use of accelerated composting of the dewatered part of the effluent is one of the ways to increase the efficiency of using waste from pig farms. For this, scientists have developed a standard series of installations that ensure the conversion of waste into high-quality organic fertilizer, however, the issue of further use of the liquid part of the waste has not been fully worked out. That is why the use of the latest wastewater treatment technologies from industrial enterprises, food and agriculture is an urgent problem. One of the promising ways to improve treatment technologies for organic pollution is the use of cavitation phenomena and electrohydraulic shock in the aquatic environment. Analysis of existing wastewater treatment technologies shows that today environmentally friendly methods are being intensively developed, which are an alternative to chlorination and other chemicals. In recent years, the development and research of the operation of electro-pulse methods for disinfecting liquids, based on the creation of a high-voltage discharge in a liquid, the so-called electrohydraulic effect, have been actively pursued. Taking into account the long-term studies of the processes occurring during the electrohydraulic shock, the implementation of this method has not gone beyond the bench tests and is at the development stages. To study the effect of electrohydraulic treatment on chemical transformations of organic substances and disinfection, an experimental electric pulse installation has been developed. Waste waters of livestock complexes are characterized by organic and mineral pollution, they can have a different composition, which makes it impossible to determine the individual components of pollution. Therefore, it became necessary to find such indicators that would characterize certain properties of water without special identification of individual substances. To assess the efficiency of the electric pulse treatment of manure runoff, the BOD indicator was chosen - biological oxygen consumption and dry residue. Key words: slurry, pig feeding complex, electric pulse treatment, biological oxygen consumption
