A membrane pollution trend identification and preventive maintenance method
By combining functionalized tracers with non-contact external sensing fields, the type and spatial distribution of membrane fouling are identified, solving the problems of inaccurate membrane fouling identification and delayed maintenance in existing technologies. This enables early warning and efficient predictive maintenance of membrane systems, improving the service life and operating efficiency of membrane modules.

Abstract
The application discloses a membrane pollution trend identification and pre-maintenance method, and belongs to the technical field of water treatment. The method comprises the following steps: injecting a functionalized tracer into water flowing into a membrane system; applying a non-contact external induction field to stimulate a complex formed by the tracer and pollutants; detecting a characteristic induction signal; analyzing a pollution enrichment characteristic parameter; calculating a dynamic enrichment trend index; and triggering a pre-maintenance operation according to the index breaking through a threshold. The functionalized tracer is combined with the non-contact external induction field to stimulate the complex, and the characteristic induction signal of the complex is detected. The pollution enrichment characteristic parameter is analyzed from the signal, the dynamic enrichment trend index is calculated, and the pre-maintenance operation is triggered according to the index. Early warning, targeted identification and predictive maintenance of membrane pollution can be realized.
