Abstract
The coagulation and sedimentation process of Seawater Desalination System is a complicated physical and chemical reaction process. It has time delay and nonlinearity, which is difficult to control the coagulation process by adjusting the dosage. The traditional control method used in the project is the empirical method, that the dosage is proportional to the influent flow, but other factors are not full considered. In this paper, according to a lot of field data, the multiple linear regression method for parameter identification is used to obtained dose and other factors between the quantitative relationship with good accuracy. The mathematical model of coagulant dosage is applied in the drug control system, which can effectively overcome the shortcomings of current empirical method, such as simple, extensive, not adjusting in time, and improve the economy and reliability of operation.
