| Abstract: | Combined with reconstruction and extension project practice of Qingshan Lake sewage Treatment Plant in Huangshi City, the main contents of sewage treatment in - line monitoring are expounded. Functious, software and hardware configuration of monitoring system are introduced. Control principle of PLC in in - line monitoring of sewage treatment and I/O distributed structure are described in detail. Running practice shows that application of fieldbus - based PLC technology in in - line monitoring of sewage treatment is the best choice, and good economic and social benefits were obtained. |
