Abstract. The process of methanogenesis of pig manure in biogas plants is considered. It is determined that for intensification of fermentation processes cavitation treatment of substrate, heating and mixing of energy crops with optimum intensity of substrate loading is used. Taking into account the requirements of technologists, a mathematical model of pig manure methanogenesis in biogas plants was created. The mathematical model was implemented and tested on a simulation model using SIMULINK MATLAB environments, where the mathematical model of methanogenesis was implemented on the basis of the Mono bacterial population growth model, taking into account the extinction process given by the Kolpikov equation. Having conducted a study on this simulation model, it is determined that for the first 30 days of operation of a continuously operating apparatus of a biogas plant, with an increase in the relative flow rate of pig manure substrate from 0.08 to 0.2, the integral value of gas output is the highest 174.6 m3 at the relative velocity of the substrate 0.08 . For this process, a virtual device for performance testing has been developed in LabVIEW software environment. In the created environment visualization of all technological factors is performed and signaling of control parameters is provided. The developed software project can be tested in production conditions.
