Description
Technical field
The invention belongs to a kind of separator, especially a kind of Efficient antibacterial purifier.
Background technique
With the development of economy, people's lives level is continuously improved, and requirement of the people to household water is also increasingly
The problem of height, how safe water and healthy water use have become broad masses' concern.
However, traditional water purification catridge mostly just in water chlorine residue and heavy metal adsorbed and reduce peculiar smell, but
It is that the organic impurities being directed in water and microorganism lack necessary absorption.In the market the most common filter core be with active carbon, but
Be Active Carbon in Organic adsorbance it is limited, once Organic substance in water content is higher, adsorption effect will decline to a great extent, living
Property charcoal then seems more helpless to microorganism, is difficult to kill those bacteriums being harmful to the human body in water purification process.
Some researches show that, the most common organic pollutant is volatile organic compounds in water, be mostly by chemical plant and
Power plant is discharged into air in process of production, is then deposited in domestic water again, and such pollutant is very difficult to pre-
It is anti-, and be difficult to remove.For this pollutant, scientists study a series of methods, such as Photocatalytic
degradation of nonylphenol by immobilized TiO2in dual layer hollow fibre
Membranes. (Chem.Eng.J.2015,269,255-261.) uses light-catalysed method once text to remove volatility
Organic compound, but since it is desired that organic pollutant could be catalytically decomposed in light, it is not particularly suited for water purification filtration in this way
On core.
At the same time, in order to kill the bacterium in water, mostly use silver nano-grain as sterilization greatly in the prior art
Agent, however according to Negligible Particle-Specific Toxicity Mechanism of Silver
Nanoparticles:The Role of Ag+Ion Release in the Cytosol.(Nanomedicine
Nanotechnology, Biol.Med.2015,11 (3), 731-739.) a text report, Nano silver grain can be in practical application
Middle to assemble, so as to cause antimicrobial efficiency decline, furthermore there is also potential bio-toxicities for silver ion.
In order to overcome the above problem, Efficient antibacterial water purification catridge provided by the invention is using carbofrax material as main
Filter core, the material have biggish surface area and high absorption capacity, surface attachment have catalytic action metal material
Afterwards, even more has the ability for decomposing Organic substance in water, the present invention protects to make the filter core raising service life also use filter core
Pipe, which can be with absorption surface activating agent and some greasy dirts.Attachment silver ion is used in order to improve fungistatic effect
Sponge as antibacterial material, used the antibacterial material to solve the problems, such as that silver ion is assembled, and due to antibacterial material
The absorption of silver ion is more firm in material, and silver ion is avoided to enter in water to cause harm to the human body.
