Abstract
A disclosed cleaning agent for filtering membranes is composed of the following raw materials in parts by mass: 10-20 parts of a composite enzyme preparation, 5-10 parts of a surfactant, 5-10 parts of a water softener, 5-10 parts of a chelating agent, and 1-3 parts of a catalyst. The above raw materials are mixed according to the above mass fractions for preparing the finished product. The cleaning agent is simple in preparation method and ideal in cleaning effect, helps to effectively enhance the permeability of a membrane, improve water yield and prolong the service life of a filtration membrane.
Description
Technical field
The present invention relates to a kind of membrane material cleaning agent, relate in particular to a kind of filter membrane cleaning agent.
Background technology
Film separation is colloid, particle and the relatively high material of molecular weight in the lower trap water of extraneous motive force (pressure) effect, and water and little particles of solute are through the separation process of film.Just because of this, filter membrane is easy to the fouling because of some suspensions, metal oxide, colloid or microorganism etc.For guaranteeing the clean-up effect of filter membrane, need regularly filter membrane to be cleaned.Artificial mechanism is clean is easy to destroy filter membrane, although traditional medicament is clean, can wash part colloidal substance off, and its effect is more single, and some metal oxides are difficult for washing off.
Summary of the invention
The technical problem solving: for the deficiencies in the prior art, the invention provides the filter membrane cleaning agent that a kind of preparation method is simple, cleaning effect is desirable, can effectively increase the permeability of film, improve aquifer yield, extend the service life of filter membrane.
Technical scheme: the invention provides a kind of filter membrane cleaning agent, formed by the raw material of following mass fraction: 10 ~ 20 parts of complex enzyme formulations, 5 ~ 10 parts, surfactant, 5 ~ 10 parts of water softeners, 5 ~ 10 parts of chelating agents, 1 ~ 3 part of catalyst.
Described complex enzyme formulation adopts zytase or pectase; Described surfactant adopts AEO sodium sulfonate or neopelex.
Described water softener adopts CMC; Described chelating agent adopts citric acid or oxalic acid; Described catalyst adopts calcium chloride.
Beneficial effect: (1) products material is easy to get, preparation method is simple, with low cost; (2) product cleaning effect is desirable, can not only wash simple metal oxide and hydroxide, and can wash deposition old dirt for many years, effectively increases the permeability of filter membrane, improves aquifer yield, extends the service life of filter membrane.
