The invention provides a water-purifying multifunctional curtain which is mainly applied to the water treatment field. The curtain is mainly characterized in that the multifunctional curtain is made of layer chip type curtain-shaped water purifying materials, the curtain is of the combined layer chip structure of one or two or more layers, each layer chip is relatively independent, and all the layers can relatively move at different speeds; the curtain is mainly manufactured of two or more of a filter cloth, high-strength multi-hole sponge, activated carbon fiber and ion exchange fiber and a composite product thereof in the mode of optimizing the layer chip module combination way. The optimization manufacturing technology is selected based on the type of raw water to be treated, the water yield and water quality pollution characteristics. The multifunctional curtain has the function of purifying multiple compound polluted raw water in situ, and has the advantages of being wide in application range, good in water purification effect, small in occupied area, flexible in application way, easy to replace, regenerate and reuse and environmentally friendly.
