Abstract

The invention discloses an antibacterial concentrated water isolating net. The concentrated water isolating net is manufactured by adding an antibacterial material into a concentrated water isolating net and has an antibacterial property. By means of the concentrated water isolating net which is manufactured by adding the antibacterial material into the concentrated water isolating net and has the antibacterial property, the self-antibacterial effect of a reverse osmosis membrane component is increased by adding the antibacterial material, and thereby, a whole reverse osmosis system has a microbial contamination resistant capability; and due to the reinforcement of the antibacterial property, the advantages of greatly reducing reverse osmosis cleaning frequency, reducing the damage of a chemical cleaning solution to the surface of the membrane component and effectively prolonging the service life of the reverse osmosis membrane are achieved.

Description

technical field [0001] The invention relates to an antibacterial concentrated water separation net and a preparation method thereof, belonging to the technical field of water treatment by reverse osmosis technology. Background technique [0002] As a new, efficient and energy-saving separation technology, membrane separation technology gradually occupies an important position in the field of water and other liquid separation. At present, it has been widely used in many fields such as seawater desalination, reclaimed water reuse, and slightly polluted surface water treatment. [0003] From the proposal of seawater desalination with reverse osmosis technology in 1953, to the commercial operation in the 1960s, and after more than 50 years of development, reverse osmosis water treatment technology has been successfully applied in many fields. Reverse osmosis technology occupies an important position in the field of water and liquid separation with its new, efficient and energy-...
