Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration devices, in particular to an ultrafiltration backwashing device for rural domestic sewage. Background Art

[0002] Ultrafiltration is a membrane separation technology that can purify and separate solutions. Ultrafiltration membranes only allow solvents (such as water molecules), inorganic salts and small molecular organic matter in the solution to pass through, while retaining macromolecular substances such as suspended matter, colloids, proteins and microorganisms in the solution, thereby achieving the purpose of purification and separation. The purification of rural domestic sewage also requires the use of ultrafiltration devices to filter out rust, sand and gravel, colloids in the water, and absorb residual chlorine, odor, discoloration, pesticides and other chemical agents in the water, and remove bacteria, impurities, toxins, heavy metals, etc. in the water;

[0003] For example, the patent website discloses a water purifier that prevents dirt accumulation (publication number: CN220432454U). This device adjusts the opening size of the third one-way valve so that the pressure in the flushing pipe is greater than the pressure in the water channel. During water flushing, the filtered water in the flushing pipe will reversely clean the ultrafiltration membrane under the action of water pressure. However, this method requires water to flow over the entire ultrafiltration membrane, which takes a long time, resulting in poor effect and low efficiency when fully reverse cleaning the ultrafiltration membrane, resulting in a long time for reverse cleaning of the device. Therefore, a technician in this field proposed a rural domestic sewage ultrafiltration backwashing device. Utility Model Content
