Improvement of the operation processes of electrotechnology wastewater purification systems under the energy efficiency criterion

摘要

Introduction. The research is conducted to justify of substantiating scientific foundations for the functioning of electrotechnological wastewater treatment systems of continuous production. Materials and methods. The approaches towards the creation of technical specifications for continuous production are being analyzed, taking into consideration the criteria of energy efficiency. The study is based on the methods of active and passive experiments on pilot plants and industrial equipment, the methods of cross-effects of water purification methods, the methods of the dominant dynamic pollutant, the modeling concept based on the notations of the universal modeling language UML for efficient processing of measurement information. Results and discussion. The architecture of the control system with adaptive adjustment of control strategies in real time is substantiated. The system makes it possible to make decisions under conditions of disturbances of natural and man-made origin, taking into account the criterion of energy efficiency. The generalized system includes: a local control system and a decision subsystem with an input signal filtering unit (the decision subsystem contains a block for adaptive formation of control strategies in real time based on Kohonen self-organizing maps). Practically implemented approaches to the object-oriented creation and implementation of technological regulations for combined electrotechnological systems for wastewater purification of continuous production. This made it possible to improve the energy efficiency of multicomponent effluent purification processes for a meat processing enterprise deviating the energy efficiency criterion from zero ± 9.6 %, and small metallurgy ± 3.4 %. The synthesis method of object-oriented technological regulations was further developed to improve the control algorithms for combined electrotechnological water purification systems of continuous production based on the energy efficiency criterion, based on assessing the efficiency of using energy resources as an integral parameter for the removal of pollutants from effluents. Intelligent energyefficient control of the process of removing the contaminants from wastewater is being realized through the synthesis of software and information control of the combined electrotechnology wastewater purification systems based on the object-oriented technical specifications for operation. Conclusion. An improved method for managing the operation of electrotechnological wastewater treatment systems for continuous production ensures compliance with the requirements for the efficient use of energy resources and environmental safety.
