Problems solved by technology

[0003] At present, most of the commonly used water purification devices are large-scale water purifiers, such as RO reverse osmosis water purifiers and ultrafiltration membrane water purifiers, etc., which are large in quality and bulky and inconvenient to carry. There are still a lot of gaps in the field of outdoor water purification equipment with strong water purification capabilities
[0004] At the same time, for outdoor water, there are some special conditions, such as the water source has not been sterilized, there are a lot of bacteria or viruses, which may cause serious diseases; excessive sunlight may accelerate the deterioration of water quality

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...

Abstract

The invention discloses a water purification membrane, and belongs to the technical field of water purification devices. The water purification membrane is of a three-layer structure which comprises arough filtering layer, a fine filtering layer and a sterilizing layer which are laminated in sequence, water is filtered through the rough filtering layer, the fine filtering layer and the sterilizing layer in sequence, the rough filtering layer is a porous Ti membrane, the fine filtering layer is a nano-photocatalyst material, and the sterilizing layer is nano-silver. By innovatively conductingturbidity removal on the water though the rough filtering layer, decomposing the water through the fine filtering layer, and conducting sterilizing through the sterilizing layer, sterile drinking water with high purity is obtained. The water purification membrane is very simple in structure and very convenient to use, and what is only needed is to put the water purification membrane in a containeropening; meanwhile, energy consumption is not required, and the using cost is very low.

Description

technical field [0001] The invention belongs to the technical field of water purification devices, and in particular relates to a water purification membrane used for emergency water supply in military operations or natural disaster environments. Background technique [0002] Bacteria and algal organisms that can cause human diseases often exist in natural water. Therefore, water treatment is very important to human society and involves a wide range of applications. Nowadays, due to the excessive use and exploitation of resources, the limited resources are becoming more and more scarce. There are more and more natural disasters and competitions around resources. There are more and more people hiking in the wild. In an environment far from artificial water purification, how to facilitate It is very important to obtain potable water quickly. [0003] At present, most of the commonly used water purification devices are large-scale water purifiers, such as RO reverse osmosis wa...
