Abstract
The invention provides a kind of filter medium for removing running water chlorine residue, filter core and preparation method, comprise the following steps：（1）Tea component is immobilized in filter medium is obtained on carrier；（2）Tap water filter filter core is prepared using the filter medium.Be immobilized in for tea component filter medium be obtained on carrier by the present invention using the dechlorination water purification function of tea component, can require to make various filter cores according to water quality situation, treatment water and field of employment etc. using the filter medium；Carrying out running water chlorine residue treatment using the filter core will not bring secondary pollution into, and do not influenceed by water temperature and quality using process, solve the problems, such as that calcium sulfite filter core may not apply to that daily life drinking water neutralization activity carbon filtration core adsorption capacity is limited and KDF filter cores are because water quality impact causes failure.Therefore, tea component filter core is not only safe and nontoxic, and will not bring secondary pollution into water body, and the water dechlorination that can meet people's various fields of recent life is required.
Description
Technical field
The present invention relates to a kind of filter medium for removing chlorine residue in running water and preparation method thereof, it is made up of the filter medium
Filter core, water purifying plant and drinking Fountains.
Background technology
At present, urban life running water mainly carries out sterilization using liquid chlorine or bleaching powder, in order to suppress remaining in water
Pathogen, virus and other pathogenic organisms breeding once again, water after chlorination must remaining appropriate chlorine residue, to ensure
Lasting sterilizing ability.Specified according to national running water standard, the chlorinty of municipal tap water pipe network is not less than 0.3 mg/litre
Standard, although this standard ensure that the safe handling of drinking public water supply, but the chlorine residue can and water in organic substance make
With, harmful chlorinated organics are produced, on the one hand influence the mouthfeel and smell of water；On the other hand drink for a long time and be also possible to
Liver, the function of kidney central nervous system are damaged, the composition of peripheral blood is influenceed, suppresses thyroid function；Furthermore, Long Term Contact
Running water containing chlorine residue, can cause skin aging and breathing problem, and chlorine residue can by skin or breathing be absorbed by the body so as to
A certain degree of carcinogenesis is produced, is seriously threatened to human body health care belt.It is therefore desirable to carry out dechlorination operation to running water,
To eliminate the harm that chlorine residue brings.
At present, conventional running water chlorine residue minimizing technology includes charcoal absorption, KDF filterings, in sulfur-based compound and wait.
Chlorine residue and organic chemicals in water are mainly adsorbed in charcoal absorption by physisorption.But use and live
There is following shortcoming as antichlor in property charcoal：（1）Activated carbon is limited by adsorption capacity, activated carbon filter core it is effective
Service life is also very short, and can cause failure because the accumulation of dirt is blocked；（2）After some materials of charcoal absorption,
Easily the hotbed as bacterial reproduction, causes water secondary pollution；（3）When water temperature is higher (such as shower water), activated carbon is inhaled
Attached ability can rapidly disappear, and cause activated carbon to fail.
KDF filterings are a kind of high-purity copper kirsites of KDF liquid handlings company of U.S. production, are also that one kind is widely used
Antichlor.But the method equally exists shortcoming：（1）The Copper-zinc alloy material that KDF filter mediums are used is expensive, and
Zinc ion and copper ion can be introduced in water, secondary pollution is caused to water body；（2）Limited by its mechanism of action, KDF can not go
Chloramines in water removal, and its dechlorination effect also becomes very poor in cold weather conditions；（3）The dechlorination effect of KDF receives hydraulic pressure and water
Matter influence it is larger, the KDF when hydraulic pressure is not big enough and cannot work, when water quality is poor, the dirt that KDF is filtered out can be covered
KDF is caused to fail rapidly on KDF surfaces.
In sulfur-based compound and chemically reacted with the chlorine residue in running water using chemical substance calcium sulfite, neutralize
Chlorine residue composition in running water.The method usually as industrial water dechlorination because calcium sulfite and residual chlorine reaction are given birth to
Into product it is most of poisonous to human body, bring secondary pollution to running water, the use in daily life drinking water is still suffered from
Security risk.
The content of the invention
Defect it is an object of the invention to overcome prior art, there is provided a kind of filter medium, filter core and preparation method thereof,
The filter medium effectively removes the chlorine residue in running water, and will not bring secondary pollution into water body.Using the filter medium structure
Into filter core not only have chlorine residue clearance high, and method is simple, low cost.
The present invention uses following technical scheme：Tea component is fixed on filter medium is obtained on carrier, then using Jie
Matter prepares tap water filter filter core.
In some embodiments, tea component can include：Tealeaves, tea powder, tea extract, tea polyphenols, vegetable soda, egg
White matter, amino acid, vitamin, pectin element, organic acid, lipopolysaccharides, carbohydrate, enzyme, pigment, inorganic mineral element or they appoint
Meaning combination.
In some embodiments, carrier components can include：It is natural polymer subcarrier, synthetic organic polymer carrier, inorganic
Carrier or magnetic macromolecular microsphere, wherein natural polymer subcarrier mainly include shitosan, sodium alginate or starch, synthesize organic
Macromolecule carrier mainly includes polyvinyl alcohol, polyethylene glycol, polyurethane or carboxymethylcellulose calcium, and inorganic carrier mainly includes porous
Ceramics, activated carbon, diatomite, Silica hydrogel, micropore glass, foam metal or aluminium, montmorillonite, magnetic macromolecular microsphere mainly include
For ferrimagnetism microballoon, nickel nano-magnetic microsphere, cobalt nano-magnetic microsphere, alloy magnetic microsphere, magnetic amorphous alloy are micro-
Ball or magnetic composite microsphere.
In some embodiments, process for fixation can include：Absorption method, covalent coupling method, cross-linking method, flocculence or embedding
Method.
In some embodiments, the weight ratio of tea component and carrier can include in filter medium：0.1-99.9:0.1-
99.9。
In some embodiments, filter core is made up of foregoing filter medium.
Technological progress acquired by the present invention is：
The present invention utilizes the dechlorination water purification function of tea component, and being fixed is made a kind of new environment-friendly high-efficiency on carrier
Running water chlorine residue removes medium, and the chlorine residue removal filter core that can be applied to drinking water, industrial water is made using the medium, and this is removed
Chlorine medium and filter core have following advantage：
1st, it is not only safe and nontoxic completely with edible tea component as material, and secondary pollution will not be brought into water body
Thing, solves the problems, such as that sulfur-based compound is produced to the toxic chemical substance of human body；
2nd, good stability is respectively provided with different water temperatures, is not influenceed by water temperature change, people's life can be met each
The running water chlorine residue removal in individual field is required；
3rd, can be required according to water quality situation, treatment water and field of employment etc., make the filtering filter of different carriers filter medium
Core, solves activated carbon except the limited defect of cl material adsorption capacity and KDF filter mediums are because the influence of water quality causes failure
Problem.
