Process for fine treatment and deep iron removal through response type external variable-frequency electromagnetic field

The invention relates to the technical field of water treatment, and discloses a process for fine treatment and deep iron removal by using a response type external variable-frequency electromagnetic field, which comprises the following steps: S1, mounting an electromagnetic generating device; s2, detecting iron ion concentration and hydrogen conductivity at an inlet; s3, performing frequency conversion treatment on the condensed water; s4, detecting the total iron content and the iron ion concentration at an outlet; and S5, evaluating the deironing effect of the condensed water. According to the invention, an external variable-frequency electromagnetic field is added to a condensate water system, and non-polar iron substances are induced to be subjected to sexual change and are converted into polar iron particles and iron ions, so that the separation effect of an iron remover and a fine treatment unit can be fully exerted, and deep removal of iron content in a water vapor system is realized; an external elect
