Plant Wastewater Treatment System Based On PLC Conrol

As is known to all,water is the source of life,and water plays an irreplaceable role in the production and life of human beings.However,in recent years,the rapid development of China’s economy,a large number of industrial wastewater and domestic sewage are discharged directly into rivers and lakes,which seriously affect the survival of mankind.Therefore,the industrial wastewater and domestic sewage treatment is imminent.In this paper,the power plant waste water as the research object,in-depth analysis of the control system for industrial wastewater treatment.The problem with the plant wastewater treatment system for the paper,the main research-based Siemens 300 series PLC wastewater treatment plant control system design related content,control strategy from the needs of the system,system security and system features four aspects of the paper conducted a comprehensive analysis and research,in-depth study of the wastewater treatment plant knowledge,learning and summed up in the field of advanced technology.Through research and analysis and mathematical model waste water PH value and control theory,combined with time-delay characteristics of a chemical reaction,before the discovery of the presence of the corresponding control and regulation is slow and there will be a large overshoot problem,so the fuzzy PID related concepts,fuzzy control theory,the use of Simulink to build a simulation model,obtained by simulation of fuzzy PID control with excellent conclusions,the final completion of the power plant process wastewater treatment system,the overall control system,and the value of PH F-PID research and design of the controller.This article aims to provide a complete and efficient wastewater treatment plant control system solutions,subject to the actual project as the basis for the entire wastewater treatment system control functions are fully described in the design and implementation of control system equipment selection,network construction,interconnect hardware,field control boxes and the production site equipment control loop.Siemens as a system controller,the configuration of lower computer control system hardware module,a programming technology production equipment and process control PH value of the wastewater treatment system of regulation F-PID controller.Monitoring system is carried out on Siemens WinCC V7.0 configuration software platform design and development,and the use of SQL Server database system to process the information in the original report,combined with software configuration data display controls,visual image display system for user data the final user is presented with a simple and beautiful real-time monitoring screen.Finally,the full text of the summarized,and based on this research paper was the next prospect.
