The invention discloses a preparation method of a polymer film modified by blending antibacterial and heavy metal removal. -The cyclodextrin composite functional layer is evenly distributed on the cross section, the outer surface layer and the inner surface layer of the polymer film. The antibacterial and heavy metal removal blend-modified polymer membrane has excellent properties such as adsorption of heavy metals, organic dyes and phenolic pollutants, and can be widely used in the treatment of deep purification of drinking water, industrial sewage, dye wastewater and agricultural wastewater. The preparation method not only has the advantages of simple and fast method, strong universality, etc., but also greatly improves the compound amount of cyclodextrin. |
