Abstract
The invention discloses an alkaline cleaning agent and a bactericide applicable to ultra-filtration membranes or reverse osmosis membranes. The alkaline cleaning agent comprises 5-10% of sodium hydroxide, 2-5% of polyphosphate, 0.5-2% of anionic surfactants, 5-10% of permeating agents, 20-30% of chelating agents, 2-5% of dispersing agents, 5-10% of stripping agents and the balance water. The alkaline cleaning agent and special reverse osmosis bactericides are mixed with one another to obtain the bactericide. The bactericide comprises 2-3% of the alkaline cleaning agent, 0.1-0.5% of the special reverse osmosis bactericides and the balance water. The alkaline cleaning agent and the bactericide have the advantages that the cleaning agent is excellent in cleaning performance, is in a compound type formula and is little in environmental pollution; the alkaline cleaning agent and the bactericide are not single basic chemical raw materials, accordingly, good cleaning effects can be realized, and the alkaline cleaning agent and the bactericide are suitable for diversified pollutants and low in application amount.
Description
Technical field
The present invention relates to a kind of alkaline cleaner suitable in ultrafilter membrane or reverse osmosis membrane and antibacterial.
Background technology
The current domestic dependence on import of reverse-osmosis membrane element, mainly three brands of the U.S.: Tao Shi DOW, Hydranautics HYDRANAUTICS；General Electric Co. Limited's (GeneralElectricCompany is called for short GE).Ultrafiltration membrane elements is with the import U.S. GE, Tao Shi, and domestic a few major company is produced as main.
Reverse-osmosis membrane element pore size filter is 0.5～10 nanometer, the impurity in water, antibacterial, salinity carries out physics and intercepts and remove, enter domestic application only 20 years less than, be novel mechanical water processing mode.The scientific maintenance of reverse osmosis, it is most important that ensure the equipment with high desalinization of membrane component and the high water yield, extend the service life of membrane component, at present domestic do be still short of very much.Ultrafiltration membrance filter aperture is 0.001-0.02 micron, intercepts the impurity filtered in water body to reach the purpose purified water.
Above-mentioned membrane component manufacturing company, the FAQs produced during membrane component is run (reverse osmosis: aquifer yield declines, salt rejection rate declines, pressure reduction raises；Ultrafiltration: aquifer yield declines, pressure reduction raises), it is proposed that membrane component is carried out safeguarding the superperformance to recover membrane component, but the cleaning process guidance provided is all fairly simple narration.Abluent used is also the general chemical product (sodium hydroxide, sodium hypochlorite, citric acid, EDTA, sodium tripolyphosphate, dodecylbenzene sodium sulfonate) being readily available on market, for the light contamination of film, additionally it is possible to meet cleaning requirement.System operation situation can be improved after cleaning.Not thorough owing to cleaning scrubbing, so it is not long to hold time, after running the short period, system operational parameters is undesirable again, it is necessary to again clean, and the cleaning frequency is too short.
Summary of the invention
In order to overcome above-mentioned deficiency, the present invention provides a kind of alkaline cleaner suitable in ultrafilter membrane or reverse osmosis membrane and antibacterial.The alkaline cleaner of the present invention have employed compound prescription, various ingredients fits over together, cooperative effect substantially increases, compare single alkaline membrane cleaning agent formula (alkaline cleaner such as sodium hydroxide, sodium tripolyphosphate, EDTA tetra-sodium), to the Organic substance on film surface, colloid, microorganism mucosa, sulfate scale removal effect better.
The cleaning and sterilization agent of the present invention, belongs to non oxidizing bactericide, membrane component is not damaged, and performance is gentle.Coordinate alkaline cleaner to use, the cleaning performance being satisfied with very much can be reached.
Technical scheme is as follows:
