Embodiment Construction
[0021] In order to deepen the understanding of the present invention, the technical solutions of the present invention will be further described in detail below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.
[0022] The preparation method of the anti-pollution concentrated water channel network of the present invention is to coat the treatment liquid on the surface of the concentrated water channel network to improve the hydrophilicity of the surface of the concentrated water channel network to reduce its adsorption capacity for pollutants; the specific steps are as follows: :
[0023] Prepare a PVA aqueous solution with a mass percentage of PVA of 0.2 to 5%;
[0024] preparing an aqueous solution of an adhesive linker with a mass percentage of 0.1 to 2% of a crosslinking agent and a mass percentage of 0.1 to 2% of an inorganic acid;
[0025] The two aqueo...

Abstract
The invention relates to the technical field of water treatment, in particular to a method for preparing an anti-pollution concentrated water runner net, application thereof and a reverse osmosis device. The anti-pollution concentrated water runner net is prepared by coating anti-pollution treatment solution on the surface of a concentrated water runner net, so that the hydrophilicity of the surface of the concentrated water runner net is improved so as to reduce the adsorption capacity of the net on pollutants. The anti-pollution concentrated water runner net is used for manufacturing the reverse osmosis device, so that the pollution resistance of the reverse osmosis device is improved. According to the invention, the salt removing rate of a membrane module of the reverse osmosis device manufactured from the anti-pollution concentrated water runner net and the stability of the membrane flux are improved, so that the pollution resistance of the reverse osmosis device is improved, and the service life of the reverse osmosis device is prolonged. Moreover, the method is simple in process, the needed preparation time is short, and large-scale production is easy to realize.
Description
technical field [0001] The present invention relates to the technical field of reverse osmosis treatment of sewage, in particular to a method for preparing an anti-pollution concentrated water channel network, its use, and a reverse osmosis device. Background technique [0002] Reverse osmosis sewage purification method is an efficient water purification method, which has the advantages of high efficiency, low cost, no phase change, easy integration, modularization and automation, etc. It is widely used in the preparation of high-purity water in the electronics industry, medical water preparation, seawater desalination , brackish water desalination, sewage recycling and many other fields. With the shortage of global fresh water resources and the increasingly serious water pollution, reverse osmosis sewage purification technology is playing an increasingly important role in water purification. However, the reverse osmosis membrane of the reverse osmosis device faces various ...
