NOVELTY - Preparing electrically controlled adsorption film comprises (a) mixing surfactant, water and conductive material, dispersing, obtaining conductive material dispersion liquid, loading on bottom film by the mode of vacuum-assisted physical deposition, and obtaining conductive film, (b) mixing surfactant, water, additive and electropolymerization monomer, and obtaining electropolymerization electrolyte, (c) mixing the conductive film and the electropolymerization electrolyte to obtain a conductive film with an adsorption functional layer; and (d) soaking and cleaning the conductive film successively to obtain the electronically controlled adsorption film, where the step (a) and step (b) are in no particular order. USE - The adsorption film is useful in preparing self-cleaning of the electric control adsorption film (claimed). ADVANTAGE - The method avoids the topical medicine in the sewage treatment process, and realizes the synchronous remove pollutant and small molecular weight organic matter. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Electropolymerization device used in the preparation method, comprising an electrolytic cell and a three-electrode system placed inside the electrolytic cell, a flat plate type electropolymerization device and a hollow fiber type electropolymerization device, the three-electrode system includes a working electrode, a reference electrode and a counter electrode, and the reference electrode includes a silver/silver chloride reference electrode; Electrically controlled adsorption film obtained by the above mentioned method; and Self-cleaning of the electric control adsorption film, comprising placing the polluted electronically controlled adsorption membrane in an electrochemical filtration device, performing reduction and oxidation, and obtaining a clean electronically controlled adsorption membrane.
