The process of modeling the operation of a hydraulic mixerreactor of the partition type as a control object in the regulation of pH and Eh parameters in wastewater treatment processes is considered.The specifics of work, the physical basis of this control object and its simulation modeling in sewage treatment automation systems are defined. To adjust pH and Eh in practice, mixer-reactors are used,where the added reagent is first mixed with wastewater, and then the corresponding chemical reactions take place. For one of the types of mixer-reactors (partitioned) a three-dimensional simulation of the process of changing the pH when adding a portion of the reagent was carried out. During the simulation, graphs of the dependence of the pH value change over time at different points of the mixer-reactor were derived. Also, to confirm the adequacy of the model, experimental studies were conducted in industrial conditions. The simulation results show that the developed mathematical model corresponds to the experimental dependences. The results of the conducted research can be used to optimize the geometric dimensions of this mixerreactor and new control algorithms for the most effective regulation of wastewater parameters.
