Intelligent denitration control method and system

The invention belongs to the technical field of denitration, and provides an intelligent denitration control method and system.The intelligent denitration control method comprises the steps that the duration of obtaining fresh water through dialysis method desalination is compared and analyzed, a dialysis abnormal signal is obtained, and ion migration data in the dialysis method desalination process is obtained and analyzed; judging whether the dialysis abnormity in dialysis method desalination is caused by the abnormal ion migration rate or not; the method comprises the following steps: acquiring energization data of an ion dialyzer, performing combined analysis on the energization data and migration data to obtain an influence evaluation value, determining whether an influence relationship exists between the change of the energization amount and the change of the ion migration rate according to the influence evaluation value, and acquiring an energization regulation and control coefficient which comprises a
