Abstract
In order to control the coagulant dosage better in water treatment systems, a mathematic model used for coagulant dosage control in water treatment process is established by the method of mechanism and distributed parameter system modeling. It includes the basic processes of a water treatment system, i.e. coagulation, flocculation and sedimentation. The dynamic response relations between the coagulant dosage and the water turbidity after flocculation and sedimentation can be obtained through this model, and the influence of water plant design parameters on water treatment effect can be analyzed by dint of simulation results of the model. The example results simulated by the model show the dynamic influence of the disturbance of incoming water on the water turbidity after flocculation and sedimentation, and it is close to the real experimental data in a water plant. This model can be used for water treatment control system and offers a good simulation and analysis platform for nonlinear control methods of water treatment.
