RO reverse osmosis membrane treating agent and preparation method thereof

Abstract

The invention discloses an RO reverse osmosis membrane treating agent and a preparation method thereof, and the treating agent comprises the following components in percentage by weight: 15%-17% of epoxysuccinic acid, 8%-10% of sodium hypophosphite, 5%-10% of maleic anhydride, 55%-60% of deionized water, 8%-10% of acrylic acid, 0.1%-0.2% of 1, 3-dicyclohexyl 1, 1, 3, 3-tetrakis[(norbornen-2-yl)ethyldimethylsiloxy]disiloxane, 0.1%-0.2% of 2-(dimethylamino)vinyl-3-pyridyl ketone, 1%-4% of trans-2-(4-tolyl)vinylboric acid and 0.1%-0.6% of potassium peroxodisulfate. The scale inhibitor can efficiently work under the conditions of high hardness, high alkalinity and high pH value, and scale inhibition can be effectively carried out without using sulfuric acid to adjust the pH value.

Description

technical field [0001] The invention relates to the technical field of water treatment agents, in particular to an RO reverse osmosis membrane treatment agent and a preparation method thereof. Background technique [0002] Reverse osmosis is a membrane water treatment method developed rapidly in the late 20th century. It is used for the desalination of seawater and brackish water, the production of desalinated water, pure water and high-purity water, and the recovery of water in sewage. It is the most effective method at present. one. [0003] Reverse osmosis agent is a kind of water requirement that can be used in electronics, electric power, chemical industry, pharmaceutical and food fields. Its core technology is because the reverse osmosis membrane is made of special materials such as acetate fiber and polyester amine fiber. Reverse osmosis membrane separation technology is one of the physical desalination technologies. The ion concentration in the reverse osmosis devi...

AI Technical Summary

Problems solved by technology

[0004] The reverse osmosis membrane reagent is a membrane with permeability, which can selectively permeate other components in the solution under the action of external pressure, so as to achieve the purpose of water desalination and purification, while the insoluble salt in brine, Metal oxides, bacteria, oxidizing substances, organic matter and silica gel may cause membrane pollution. Therefore, in order to reduce the pollution of the reverse osmosis membrane, prolong the cleaning cycle and service life of the reverse osmosis membrane, and improve the water production rate and desalination rate , before supplementary water enters the reverse osmosis equipment, pretreatment and addition of reverse osmosis dispersants are required; however, the existing RO reverse osmosis membrane treatment agents are often costly and poor in effect, especially in high hardness, high alkalinity and high pH Under the condition of low value, it is unable to play an effective role
