Embodiment Construction
[0020] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.
[0021] like figure 1 As shown, a kind of water purification membrane 1 provided by the present invention has a three-layer structure including a coarse filter layer 2, a fine filter layer 3 and a sterilizing layer 4 stacked in sequence, and water passes through the coarse filter layer, the fine filter layer and the sterilizing layer in sequence. Specifically, the coarse filter layer is a porous Ti membrane with a pore size of 0.22 μm, which can filter out particles and bacteria with a diameter > 0.22 μm to improve the turbidity of water. In addition, the Ti membrane The surface will increase the positive charge, which will strengthen the adsorption during the water pu...
