Abstract
The invention provides a kind of hyperfiltration membrane cleaning agent, comprise with parts by weight: neopelex 7 ~ 12 parts, polyoxyethylene fatty alkyl ether sulfonate 5 ~ 8 parts, carboxymethyl cellulose 2 ~ 6 parts, natrium citricum 3 ~ 9 parts, 1 ~ 4 part, sodium carbonate, 2 ~ 8 parts, NaOH, pectase 0.1 ~ 0.6 part, aliphatic APEO 1 ~ 7 part, potassium silicate 0.5 ~ 1.9 part.Hyperfiltration membrane cleaning agent washing power of the present invention reaches more than 95%; Rinsing performance is superior, to ultrafiltration apparatus without harm, membrane flux can be made to return to normal level, and can maintain certain cycle after avoiding the tendency of film deterioration, cleaning; Decrease cleaning frequency, reduce processing cost, cleaning waste liquid easily processes.
Description
Technical field
The invention belongs to technical field of water treatment chemical, be specifically related to a kind of hyperfiltration membrane cleaning agent.
Background technology
The oily waste water of iron company's cold rolling mill is mainly containing the pollutant such as mineral oil, emulsifying agent, and its direct discharge can bring serious pollution to environment, and iron and steel enterprise generally adopts tubular type alundum (Al2O3), zirconia milipore filter carries out oil removal treatment.But due to reasons such as the formation of solute gel layer and the concentration polarizations of milipore filter, Pollution of Ultrafiltration Membrane can be caused, cause flux depression, ultrafiltration deleterious, even make film form irreversible membrane fouling, bring heavy losses.Therefore, only have and select effective cleaning agent and cleaning method, recover the service life that membrane flux extends milipore filter, the demand of hyperfiltration treatment could be met.
The cleaning of milipore filter divides alkali cleaning, pickling and rinsing three step, and committed step is wherein alkali cleaning.At present, each enterprise uses commercially available general alkaline cleaner, and not only price is high, and because of the specific aim of formula strong, degreasing result is not good, and after cleaning, life cycle is short, recycles number of times few, causes enterprise operation cost to remain high.Therefore, how for the feature of enterprise's oily waste water, the milipore filter cleaning fluid of research and development out-degree and environmental requirement, high efficiency low cost, becomes the key issue that enterprise is in the urgent need to address.
Summary of the invention
The object of this invention is to provide a kind of hyperfiltration membrane cleaning agent.
A kind of hyperfiltration membrane cleaning agent, comprise with parts by weight: neopelex 7 ~ 12 parts, polyoxyethylene fatty alkyl ether sulfonate 5 ~ 8 parts, carboxymethyl cellulose 2 ~ 6 parts, natrium citricum 3 ~ 9 parts, 1 ~ 4 part, sodium carbonate, 2 ~ 8 parts, NaOH, pectase 0.1 ~ 0.6 part, aliphatic APEO 1 ~ 7 part, potassium silicate 0.5 ~ 1.9 part.
As the further improvement of foregoing invention, with parts by weight, described hyperfiltration membrane cleaning agent is also containing polymerization of sodium phosphate 0.8 ~ 3.5 part.
Above-mentioned hyperfiltration membrane cleaning agent is first mixed with the aqueous solution that mass percentage is 1%, then regulates the pH value of the aqueous solution to be 10 ~ 11 before using.
Hyperfiltration membrane cleaning agent washing power of the present invention reaches more than 95%; Rinsing performance is superior, to ultrafiltration apparatus without harm, membrane flux can be made to return to normal level, and can maintain certain cycle after avoiding the tendency of film deterioration, cleaning; Decrease cleaning frequency, reduce processing cost, cleaning waste liquid easily processes.
