Design Of Waste Water Treatment System Based On PLC

With the development of modern industrial automation,the traditional sewage treatment control system has a low degree of automation.In order to improve the effect of sewage treatment,this article combines the actual situation of the sewage treatment plant,according to the technological characteristics of the sewage treatment process and the overall requirements for the control system,designed Sewage treatment control system with S7-1200 PLC as the core controller.In view of the shortcomings of the traditional sewage control system,firstly,the overall control system of sewage treatment was designed,and the connection methods of industrial application networks such as DCS,Profi Bus fieldbus,and industrial Ethernet were compared and analyzed;secondly,the control circuit of the sewage treatment process and S7-1200 PLC control program was studied.Finally,the control program of the host computer is designed to control the various technological processes in the sewage treatment system.Select the SIMATIC STEP7 programming software programming in the Portal,select the YSI6600V2 multi-parameter water quality detection system to detect the sewage treatment effect,design the process flow,record query,alarm,report,parameter setting and other operation screens,and realize the onsite equipment through SIMATIC Win CC monitor.Fig 42;Tab 5;Ginseng 50;Type7;...
