Abstract

The invention provides a reverse osmosis membrane scale inhibitor which comprises the following raw materials: benzalkonium chloride, 2-Hydroxyphosphonoacetic Acid, sorbic acid, hydroxyproline and sodium hexadecyl sulfonate. The scale inhibitor also includes the following raw materials: 2-Hydroxyl-4-(methylthio) butyric acid, dodecyl dimethyl benzyl ammonium chloride, ellagic acid and beta sitosterol. With the scale inhibitor, the desalination rate of an aromatic polyamide spiral coiled composite membrane is more than 99.5%, and the scale inhibition rate is 99% or more when the water treatmentcapacity is 100 m<3> / h by use of the reverse osmosis membrane scale inhibitor.

Description

technical field [0001] The invention relates to a scale inhibitor, in particular to a reverse osmosis membrane scale inhibitor, its preparation method and its application in the treatment of petroleum coke calcined raw water, which belongs to the technical field of scale inhibition. Background technique [0002] A functional semipermeable membrane that allows solvent molecules to pass through but not solute molecules is a reverse osmosis membrane. [0003] CN201510288866.1 An environment-friendly reverse osmosis membrane scale inhibitor and its preparation method and application. The environment-friendly reverse osmosis membrane scale inhibitor is composed of the following substances: tannin, dodecylbenzyl ammonium bromide, citric acid Sodium, polyaspartic acid, zinc salt, potassium sodium tartrate. The preparation method is to mix the above-mentioned substances uniformly in proportion. The method of use is that the environment-friendly reverse osmosis membrane scale inhib...
