Abstract
For Stripping is the main factor of the efficiency of ammonia removal, and the traditional PID control can't get good control on sewage temperature, the sewage temperature fuzzy controller based on PLC was designed.The design adopted the timer interrupt block to implement two-dimensional fuzzy control of discrete domain,and adjusted steam addition amount by changing steam regulation value opening to realized precise control of sewage temperature.The experimental results showed that the practical control precision could reach 1.5℃, the design could effectively improve the efficiency of the deamination of Stripping and cost savings.
