Beiliu Wastewater Treatment Plant Automatic Control System Design And Realization

The current city sewage treatment plant control system responsible for the plant electrical equipment control and the production process to achieve. With a high degree of automation of the sewage treatment plant can improve the operating environment, improve production efficiency, reduce labor intensity, to achieve the optimal operation and production process and operation of intelligent scheduling of network communication, can give full play to advantages, realize the sharing of information resources, so as to achieve the purpose of saving energy and reducing consumption, economic operation. Aiming at some sewage treatment plant automation degree is not high phenomenon, the development of the automatic control system.In this thesis, design of the automatic control system of working content: ( 1) the control system hardware and software related technologies are described, including Siemens hardware module, S7 development software, configuration software; ( 2) to control the system needs analysis, including the control system functional requirements, feasibility demonstration; ( 3) according to the demand analysis, undertake design and implementation of automatic control system, including the hardware PLC procedures and the PC configuration software application design; ( 4) on the automatic control system for testing, aiming at the control system function test.Finally, according to the above content, combined with the actual design of wastewater treatment plant, a sewage plant automatic control system, real-time monitoring, control equipment on and off, historical data query and other functions.
