The development of electrical technologies and its use in various fields of life has become an important element in the search and development of new effective methods for treating livestock waste. An increase in the production of livestock products, and accordingly an increase in the amount of manure, inefficient treatment, aggravates not only environmental problems, but also negatively affects the operation of the complex itself. To solve these problems, we have developed an experimental laboratory unit for the electropulse treatment of livestock waste. The installation allows you to efficiently and quickly process waste, since the processes that occur during an electropulse breakdown in a liquid adversely affect pathogenic microorganisms, bacteria and helminths. For the most convenient and visual study of the discharge processes that occur during the experiment and obtaining information about the investigated parameters of the experimental setup, a simulation model was developed that describes the real system in action with sufficient accuracy. This type of modeling is based on the achievements of both classical and the latest computer mathematics. In MATLAB Simulink, a simulation computer model was developed on which the external and operating characteristics of the installation were determined. Based on the results of the experiment, the voltage graphs of the source, the step-up transformer and the voltage pulse graph at the time of breakdown in the working chamber were constructed, a comparison of which with the actual results of the experiment allows us to state that a slight difference in the shape of the pulse is associated with the shape of the working chamber, and is a feature of the processes that occur in electric pulse waste treatment time. The obtained results allow us to confirm the correctness of the task of modeling parameters.
