ABSTRACT

With the rapid development of the national economy, PLC-based automatic control technology has been widely used in industrial production. The automatic control system consists of Siemens PLC S7-300 module, CPU315-2PN/DP as the main control unit, the indicators of sewage of all workshops are monitored and all blowers, lift pumps, and switch valves are monitored and controlled. The upper computer software WinCC can be used to monitor and control in real time the parameters of the height, pH, temperature, oxygen content and other parameters of all the sewage treatment tanks. At the same time, all the sewage data can be archived and displayed in the form of historical curves. The company's monitoring and treatment of production wastewater in this way can greatly improve the efficiency and quality of wastewater treatment, and reduce the impact of human factors on the quality of wastewater treatment in the wastewater treatment process.
