CONTROL SYSTEM FOR WASTEWATER TREATMENT PROCESS

Abstract

The main direction of the automation of the wastewater treatment process are considered, the main blocks of mechanical and biological treatment of wastewater are shown, the entire technological treatment process and the general treatment process is described, including the reusing of disinfected water after the chlorinator. The issues of energy saving in the aeration station were investigated, the main concepts in this field were analyzed, and a structural scheme was proposed reflecting the issues to be solved and applied for the purpose of energy management (energy management) in the station. It was noted that general energy saving measures include equipping pump motors with frequency converters and soft start devices, using alternative and renewable energy, using the energy of liquid flows, connecting and opening electrical devices and apparatus with a program and a light sensor, sewage entering the station It can include the production of electricity using the temperature and output gases or the heating of auxiliary buildings and the production of energy due to the processing (incineration) of sludge and garbage obtained in the cleaning process. Considering of the complete structure of the management system of the wastewater treatment process the control algorithm was proposed. In addition to the energy management subsystem, the system includes local management-adjustment tools and subsystems necessary to manage the cleaning process itself. Keywords: wastewater, control system, energy management subsystem, control algorithm, fuzzy control.
