Continuous accumulation of the pollutant of reverse osmosis membrane retention in film inner surface and fenestra, component inlet outlet pressure differential increase, the water flowing of film
Amount and separating capacity are gradually reduced, and can not restore the water-flowing amount of film by generally rinsing, it is necessary to carry out drug cleaning to film.Film is dirty
Dye is common problem in reverse osmosis technology application process, it has also become the maximum barrier that counter-infiltration system is run steadily in the long term
Hinder.The problem of designing or run with water supply source worsening and pretreatment system, reverse osmosis membrane pollution show as serious
The combined pollution of multiple pollutant composition.Therefore, it is necessary to effectively practical cleaning techniques to realize the long-term steady of counter-infiltration system
Fixed operation, alkaline cleaner can remove organic contamination, however metal oxide and hydroxide are but difficult to thoroughly remove.
Currently, the chemical cleaning formula needle in existing cleaning agent is not strong, although being suitable for some contaminated membrane elements
Part cleaning, but the membrane component more serious for some special contaminations or damage ratio, often effect is unobvious, therefore, there is an urgent need to
Develop a kind of dedicated acidic cleaner of reverse osmosis membrane of convenient and practical excellent effect.
Summary of the invention
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows: reverse osmosis membrane acidic cleaner, including
Organic acid, organic surface active agent, acylate, fungicide, inorganic salts, the acidic cleaner is by following raw material by following
Mass percentage composition: organic acid content 20-45%；Organic surface active agent: 0.5-1.5%；Acylate: 5-15%, it is anti-settling
The deionized water of product agent 3.8-4.5%, sodium chloride 2.5-4.0%, fungicide 0.8-1.0% and surplus.
The organic acid is citric acid, oxalic acid and/or moon silicic acid.
The organic surface active agent includes sulfinic acid, α-olefin sulfonic acid, alkyl benzene sulphonate and/or poly alkyl alcohol sun ethylene
Ether.
The acylate includes sodium citrate, sodium oxalate and/or moon sodium metasilicate.
The anti-deposition agent is coconut oleoyl monoethanolamine and/or molecular sieve of Nano zeolite.
The fungicide is formaldehyde, oxime dialdehyde, bis- bromo -3- nitrilo- propionamide (DBNPA) of 2,2- and/or isothiazoline
Ketone.
The preparation method of the reverse osmosis membrane acidity cleaning agent, follows the steps below:
S1: organic acid, organic surface active agent, deionized water are stirred into 20-30min at 40-50 DEG C；
S2: being added acylate when the temperature of S1 is down to 30-35 DEG C, stirs 10-15min；
S3: being added fungicide when the temperature of S2 is down to 20-25 DEG C, stirs 10-15min.
S3: being added sodium chloride when the temperature of S2 is down to 20-25 DEG C, stirs 10-15min；
S4: the pH value for adjusting solution is 1.5-2.5, pH adjusting agent HCl.
Wherein the mixing speed of S1 and S2 is 350-500rpm, and the mixing speed of S3 is 80-120rpm.
During using this cleaning agent, the production water side of cleaned anti-seepage membrane must have sufficient pure water to supply.
Compared with the prior art, the invention has the following beneficial effects: each component combination can be played in cleaning agent formula
Solubilising removes foundry loam, removes the effect of metal oxide and hydroxide, reverse osmosis membrane acidic cleaner of the present invention and its system
Preparation Method can quickly remove dirt on reverse osmosis membrane and block up metal oxide and hydroxide, can short time fast quick-recovery it is anti-
The water yield of osmosis system reduces reverse osmosis membrane operation pressure, and manual operation is simple and convenient, greatly reduces scale removal cost, single
Solely packaging, cleaning effect are stable, easily operated, energy-saving.
