Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a multi-layer ultrafiltration membrane water treatment device. Background Technique

[0002] Ultrafiltration membranes are often used in water treatment technology. An ultrafiltration membrane is an artificial permeable membrane used in the ultrafiltration process, generally made of polymer materials such as cellulose acetate, cellulose acetate esters, etc. An ultrafiltration water treatment device is a membrane separation process driven by pressure, which can effectively remove colloids, silicon, proteins, microorganisms, and macromolecular organic matter in water. When the raw liquid flows through the membrane surface under the push of pressure, the solvent and small molecule substances pass through the membrane, while the macromolecular substances are intercepted, thus achieving the purpose of separation and purification.

[0003] The patent with the publication number CN214809887U proposes a multi-layer ultrafiltration membrane water treatment device. By setting a partition board, this treatment device can install the ultrafiltration membrane body, the second ultrafiltration membrane, and the third ultrafiltration membrane in layers, enabling each layer of ultrafiltration membrane to maintain a stable state during operation. At the same time, support columns are added to enhance the stability of the overall device and stabilize the structure of the overall device. The overall device has a simple structure and is relatively convenient for installation and disassembly.

[0004] Although the above water treatment device disassembles and assembles the ultrafiltration membrane, the existing wastewater contains relatively more impurities in the water body. Only filtering through the ultrafiltration membrane has poor filtering effect, cannot fully filter and purify the water source, and reduces the efficiency of water source treatment. In view of the above problems, a multi-layer ultrafiltration membrane water treatment device is proposed for improvement and upgrade. Content of the Utility Model
