© 2019, Institute of Advanced Scientific Research, Inc.. All rights reserved. The article discusses the technological complex of wastewater treatment (WWS) from heavy metals. Based on the review of the basic methods of modeling discrete-continuous chemical-technological systems (CTS), the feasibility of using the Petri nets theory (SP) apparatus for modeling the WWS process from heavy metals is justified. It is proposed to use a modification of Petri nets, focused on modeling and analysis of discrete-continuous XTS, by including priority transitions, label delay times in positions and transitions. Built models of the main devices that implement the process of WWS. From the SP-models of typical devices, the model of the entire installation was synthesized in the form of a modified Petri net (SME). The TRACE MODE SCADA technology has been used to develop the OSV process control system software.
