Description

Technical Field

[0001] The utility model mainly relates to the field of reverse osmosis membrane repair equipment, in particular to a reverse osmosis membrane repair device. Background Art

[0002] In the context of the "dual carbon" strategy, membrane material regeneration, treatment, and disposal are crucial components of membrane wastewater treatment's carbon emissions. Developing sustainable membrane material recycling technologies, offsetting some of these emissions through membrane material regeneration, can further enhance the competitiveness of membrane wastewater treatment technology. While my country's membrane industry has rapidly developed, it has also presented numerous challenges. For example, as membrane products reach the end of their useful life, hundreds of thousands of RO membranes are discarded annually. These discarded membranes are often discarded in the wild. Foreign countries typically use solid-waste backfilling to dispose of these discarded RO membranes. China, the world's largest membrane producer and user, has accumulated a staggering amount of discarded RO membranes over the years. However, due to the lack of standardized disposal methods in China, these membranes are not included in the national solid waste disposal catalog. Over the years, the cumulative amount of organic waste RO membranes exceeds 10 million, a massive amount that is difficult to implement. Physical backfilling is highly polluting and harmful after disposal, and is inconsistent with my country's solid waste disposal approach and the development of a green, circular economy. Therefore, recycling and resource utilization of discarded RO membranes is an effective approach that aligns with China's national conditions.

[0003] During the RO membrane repair process, a hydrophilic modification layer is coated on the surface of the reverse osmosis membrane through the co-deposition between Noria and amino-containing zwitterionic polymers. The main functional groups and carboxyl density, charge, hydrophilicity / hydrophobicity, micromorphology, roughness and other physicochemical structural properties on the surface of the repaired and regenerated RO membrane are analyzed as a function of the concentration of the co-deposition solution, and the mechanism of the effect of the concentration of the co-deposition solution on the interfacial properties of the repaired and regenerated RO membrane is revealed. In this process, the discarded RO membrane needs to be fully stretched and the co-deposition solution needs to be evenly sprayed on the surface of the RO membrane through the nozzle structure. Since the length and membrane area of ​​RO membrane filtration devices of different specifications are different, adjustments need to be made to different RO membrane specifications during the repair process. Therefore, a reverse osmosis membrane repair device is needed. Utility Model Content
