The Study on Integrated Control System of A/O Sewage Wastewater Treatment Process

Aim to solve problems of the low automatic level, high energy consumption and high labor intensity in the process of sewage treatment and combing with the actual control requirements of the worksite, this study introduces an integrated control system of sewage treatment. The system bases on the S7-300PLC, inverter and KINGVIEW software. The methods of controlling, testing and management in the process of sewage treatment via the integrated control system which consists of PLC, KINGVIEW and PC were presented. The study also discussed the content of sewage treatment process, the component structure of control system, the control principle and the design of hardware and software in detail. Finally, the results proved that the system can operates reliably and effectively.
