Abstract :
For the shortages of the traditional flow program control and time program control in the process of sewage treatment, this paper adopts a Fuzzy programming method based on PLC. The PLC and its general I/O module are involved in forming the Module Controller in hardware. We use the DO and the sludge reflux ratio as the main control parameters, and infer the best control variables by PLC discrete calculation and look-up table on line. Not only can we ensure the quality of purified water, but also save energy by using this fuzzy controller in the process of sewage treatment.
