Background The current synergistic materials such as modified adsorbents and functionalized catalytic media are used for capturing heavy metal complexes and organic pollutants, are core functional components for maintaining the stable operation of a sewage treatment process and ensuring the quality of effluent water, are key material carriers for ensuring the standard discharge of industrial wastewater and town sewage, and generate chemical bonding or strong electrostatic attraction with target pollutants through surface active sites, and the regeneration efficiency of medicament materials directly influences the purification continuity of the whole water treatment process chain, the standard reaching rate of effluent water of a water treatment system, the operation cost and the solid waste reduction level. In the prior art, a strong acid or strong alkali elution process is generally adopted, the pH value of the environment is deviated from the isoelectric point of a medicament material by utilizing acid-base regulation, so that electrostatic repulsion force is utilized to drive pollutants to separate from the surface of the material, however, when the medicament material with a complex micropore structure or high length-diameter ratio pores is treated, the elution mode based on the whole concentration gradient has intrinsic limitation, when the pollutants are anchored in the micropore depths of the material, the flow resistance inside the micropores and the hydration shielding layer at the interface prevent elution ions from penetrating, and due to the shielding effect of the interface double electric layer on elution ions, the pollutants at deep active sites are difficult to be driven to be dissociated by simply relying on the improvement of the ion strength of eluent; the prior art attempts to enhance mass transfer power by increasing elution flow rate or introducing ultrasonic vibration and the like, however, physical disturbance means often only acts on a shallow surface layer of a material, a stable hydration layer formed by a hydrogen bond network in micropores is difficult to be broken, the concentration of an eluting medicament is increased or the elution time is prolonged, the material skeleton is often induced to swell, even the loaded functional components are lost, the material is subjected to physical pulverization or purification activity attenuation after being recycled, the hardware level is limited, the existing process control method has defects in coping with microscopic mass transfer dead areas, for example, the Chinese patent application with publication number of CN112897459A discloses a green regulation method for alkali metal/alkaline earth metal cation hydrolysis medium for preparing hydrogen by magnesium-based alloy hydrolysis, the reaction rate is optimized by regulating the type and concentration of cations in the hydrolysis medium, the method essentially belongs to static component regulation, when the purifying medicament with a complex pore diameter structure is processed, a single concentration regulation mode cannot generate enough drive load to break a microporous fluid bridging structure, the secondary anchoring or mineralization of the adsorbate occurs in the deep of the pore canal, and full-depth active reconstruction is difficult to realize. Therefore, how to provide a method for breaking the hydration stability of the interface and guiding the directional migration of pollutants from the depth of the limited micropores so as to realize the in-situ efficient recovery of the activity of the water treatment agent, ensure the water purification effect, reduce the secondary pollution load and the running cost of the water purification system and solve the technical problem.
