N2 - The artificial mathematical model of feed water treatment is investigated by the method of mechanism and modeling of distributed parameter system; it includes the basic processes of feed water treatment, i.e. coagulation, flocculation and sedimentation. This model can give the dynamic response of relationship between coagulant dosage and water turbidity after flocculation and sedimentation. The influence of water plant design parameters on water treatment effect can be analyzed from the simulation results of the model. Through the model at last, we had done an analog computation to the dynamic influence of sudden changes of inlet water turbidity on the outlet water turbidity after flocculation and sedimentation, and the simulation results are very close to the real experiment datum in water-plant. This model can be used for the process control of feed water treatment and offers a good simulation and analysis platform to the nonlinear control of water treatment.
