Abstract
The invention provides a cleaning fluid for water treatment ultrafiltration membranes. The cleaning fluid for the water treatment ultrafiltration membranes is composed of deionized water, inulase, gentiobiase, citrulline, beta-amylase, zytase and aspartic protease. The deionized water in each cubic meter comprises the components of 20-60g inulase, 40-90g gentiobiase, 5-20g citrulline, 80-200g beta-amylase, 60-200g zytase and 5-10g aspartic protease. The invention further provides a method for cleaning the ultrafiltration membranes. The cleaning fluid for the water treatment ultrafiltration membranes is simple in formula and simple and easy to produce. The cleaning fluid is basically composed of active enzymes, and can effectively removing the organic pollutants in the ultrafiltration membranes.
Description
Technical field
The invention belongs to field of waste water treatment, relate in particular to a kind of water treatment milipore filter cleaning fluid.
Background technology
Increasingly mature along with membrane preparation technology, hyperfiltration technique is applied in Treatment of Industrial Water more and more widely, and ultrafiltration has the characteristics such as treatment effeciency is high, reduced investment, and floor space is little.But along with the prolongation of system operation time, the cured easily contaminated and blockage phenomenon of supermembrane, so the cleaning of milipore filter seems particularly important.The cleaning method of extensive use at present is pickling or alkali cleaning.Though the inorganic matter in the easy first striping of the method, some wastewater through organic matter in film can not be washed.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of cleaning efficiency high and can clean the water treatment milipore filter cleaning fluid of organic pollution.
The present invention solves the problems of the technologies described above taked technical scheme to be:
A kind of water treatment milipore filter cleaning fluid, is characterized in that, it by deionized water, dextrase, gentiobiase, citrulling, beta amylase, zytase, and aspartic protease form; In every cubic metre of deionized water, the amount of each component is respectively: dextrase 20-60g, gentiobiase 40-90g, citrulling 5-20g, beta amylase 80-200g, zytase 60-200g, aspartic protease 5-10g.
In such scheme, in every cubic metre of deionized water, the amount of each component is respectively: dextrase 55g, gentiobiase 90g, citrulling 20g, beta amylase 200g, zytase 180g, aspartic protease 10g.
In such scheme, in every cubic metre of deionized water, the amount of each component is respectively: dextrase 45g, gentiobiase 60g, citrulling 15g, beta amylase 135g, zytase 180g, aspartic protease 5g.
A kind of milipore filter cleaning method, is characterized in that, it comprises the following steps:
1) with acidity or alkaline cleaning fluid, milipore filter is carried out to routine and clean, and rinsed with clear water;
2) utilize above-mentioned water treatment milipore filter cleaning fluid to carry out wash cycles 15-30min to milipore filter;
3) carry out the sterilizing of milipore filter with the liquor natrii hypochloritis.
Principle of the present invention is: the citrulling added in the milipore filter cleaning fluid, it can make some microproteins and the ammonification of cutin class material melon in membrane contaminant, so that its enzyme degraded in the later stage easily is cleaned liquid.In the cleaning fluid cleaning process, aspartic protease, gentiobiase belong to excision enzyme, and beta amylase, zytase belong to restriction endonuclease, and this cleaning fluid takes full advantage of the synergy of restriction endonuclease and excision enzyme in cleaning process.Excision enzyme acts on the surface of insoluble protein, carbohydrate, fiber substance, makes these insoluble matter strand crackings, and molecular end occurs free, thereby makes cellulose be easy to aquation, and restriction endonuclease acts on the pollutant through the excision enzyme activation, produces the short chain compound sugar.Dextrase resolves into disaccharides, trisaccharide and glucose substance by the short chain compound sugar again.This class material is soluble in water, thereby reaches the purpose of removing pollutant in film.This synergy is by due to the different solid space structures of these several enzymes.
Compared with prior art, the beneficial effect that the present invention obtains is: water treatment milipore filter cleaning fluid formula of the present invention is simple, produces simple and easy.This cleaning fluid substantially all is comprised of organized enzyme, can efficiently remove the organic pollution in milipore filter.
