Description
Technical field
The present invention relates to a kind of carbon rod filter core, especially relate to a kind of multi-functional carbon rod filter core and preparation method thereof.
Background technology
Along with China's rapid development of economy, the demand of water resource is increased sharply.Simultaneously; Because the quickening of industrialization and urbanization paces; The shortage of freshwater resources and the pollution problem of water environment are serious day by day, and simultaneously people to quality of life require increasingly highly, the drinking water that how to obtain clean safety has become worldwide important topic.
Traditional running water treatment technology is still continued to use the technology in last century, generally be through coagulation (help coagulate), flocculation, sterilization, oxidation, pH value regulate, soften, chemical treatment technology such as algae removal, rivers water or underground water simply are processed into Drinking Water.Worker, Agricultural Development; The pollution of water environment, the water quality condition and the water quality of the middle of last century in the present age are completely different, traditional water treatment technology; To being master's pollutant with organic compound pollutant (BOD) and chemical pollutant (COD) at present; Can not thoroughly remove, detect during output water, even exceed standard.On the other hand, China's metropolitan transmission & distribution water trunk line is many to be to install in twentieth century five, the sixties to be equipped with, through semicentennial oxidation and corrosion; Because the effect of physics, chemistry, electrochemistry, microorganism etc., can form irregular " growth ring " gradually at the inwall of feedwater piping, and along with the growth in pipe age continuous thickening; Make that discharge section area reduces, conveyance power of water reduces and severe contamination water quality, the city tap-water pipe network is long neglected and in disrepair in addition, and maintenance management is unfavorable; Pipeline leakage is up to more than 20%; Even 40%, causing secondary pollution, safety causes anxiety.
Active carbon aspect drink water purifying in occupation of important status; Because active carbon has flourishing pore structure; Huge specific area and superpower adsorption capacity, adsorptive selectivity are good; Make active carbon become a kind of good adsorbent, be widely used in the purified treatment of drinking water.
Active carbon can be removed free chlorine and the organic pollutions such as the look in the adsorbed water, stink, agricultural chemicals, pesticide, washing agent, aromatic compound, DBPs effectively in the water effectively; Its weak point is that the large amount of organic of the top layer absorption of active carbon becomes vegetative hotbed; Cause the water outlet bacterial content to exceed standard easily; The problem that has short and bacteria breed in service life, and active carbon is bad to the removal effect of heavy metal ion in the water.At present, activated carbon product mainly is a Powdered Activated Carbon, and the Powdered Activated Carbon bulk density is low, be difficult for storing, transport and reclaim, and causes dust pollution easily.And compare with Powdered Activated Carbon, pressed active carbon has bigger size and definite shape, and higher bulk density and intensity are arranged, and no dust pollution.But its higher density and bigger size, and adhesive moulding technique, can cause its specific area to be amassed has certain loss, and adsorption effect just descends to some extent.Especially the pressed active carbon of extrusion molding prepared, because used bonding agent does not have pore-creating character, the hole of active carbon is wrapped easily and lost efficacy, institute and adsorption effect is descended greatly.
Chinese patent 200410051580.3 discloses the manufacturing approach of a kind of tap water filter material, filter and filter, is major ingredient with active ash, and it is auxiliary material that KDF1, calcium sulfite, zeolite molecular sieve and phosphate carry ag material; After mixing, through high temperature high pressure process and the column of the hollow extruded, can be removed chlorine residue in the running water effectively, can remove the heavy metal in the running water effectively by screw extruder; Good anti-bacterial effect; Avoided the pollution of nitrate, can increase the activity of water, contained multiple trace element the human body beneficial; Life cycle is long, and is effective.The weak point of this invention is to have only the comparatively ripe on the market filtrate of employing to carry out simple blend and extrudes; Wherein because just there is defective in some materials self in using; Bigger like KDF proportion; There is certain problem in the blend dispersing uniformity, and consumption hour do not have positive effect, and purifying water effect can be influenced.
Summary of the invention
The objective of the invention is to prepare the defective that active carbon filter core exists, a kind of multiple function that has is provided, can effectively remove chlorine residue, heavy metal in the running water, multi-functional carbon rod filter core that bactericidal and bacteriostatic effect is good and preparation method thereof to the existing extrusion molding that adopts.
Said multi-functional carbon rod filter core raw material by mass percentage consists of active carbon 50%～98%, modified porous material powder 1%～30%, bonding agent 1%～20%.
Said modified porous material powder can be the powder of porous material after modification, and said porous material powder is at least a in molecular sieve, zeolite, diatomite, medical stone, atlapulgite, the Woelm Alumina powder.
The grain fineness of said porous material powder is 16～500 orders.
The concrete grammar of said modification is following:
1) the porous material powder is soaked in the metal ion source solution, makes adsorption of metal ions in the metal ion source in the porous material powder, dry for use then;
2) with the material reduction after the step 1) oven dry, promptly get modified porous material powder.
In step 1), said metal ion source can adopt mantoquita, zinc salt and inorganic silver salt, and said mantoquita can be organic copper salt or inorganic mantoquita, and said zinc salt can be organic zinc salt or inorganic zinc salt; The condition temperature controllable of said absorption is 20～100 ℃, and adsorption time can be 1～4h; The temperature of said oven dry can be 80～150 ℃, is preferably 105 ℃.
In step 2) in, the temperature of said reduction can be 100～800 ℃, and the medium of reduction can be hydrogen or CO gas etc.
Optional at least a in TPO, CMC, PVP etc. of said bonding agent.
The preparation method of said multi-functional carbon rod filter core may further comprise the steps:
1) active carbon, modified porous material powder and bonding agent are mixed the back oven dry;
In step 1), said mixing can mix back dispersed with stirring 1～4h with active carbon, modified porous material powder and bonding agent; The condition of said oven dry can be 80～150 ℃ of oven dry 1～4h down.
2) composite material after will drying is poured the charge door of screw extruder into, and the heating spiral rod extruder extrude the column moulding carbon rod filter core of hollow again, and length is on demand cut off the carbon rod filter core.
In step 2) in, the temperature of said heating can be divided into three sections, is respectively: 150～350 ℃, 150～350 ℃, 150～350 ℃, extruded velocity is: 50～400rpm.
With present compared with techniques, the present invention has following outstanding advantage and effect:
1) adopts the porous material powder, have high-specific surface area, high activity, high uniformity.
2) after the porous material powder carries out modification; Form copper zinc-silver alloy body; Behind the copper-loaded zinc-silver alloy of porous material powder; Not only have chlorine residue, harmful metal ion and the bactericidal action that to remove in the water, and have the breeding that suppresses microorganism, reduce suspended solid, reduce functions such as mineral fouling.
3) active carbon and the blend of modified porous material powder are extruded, and produce synergistic action effect, further strengthen and the effect of additional active carbon.
4) has efficiently, remove fast the effect of harmful substance in the water.
5) service life of prolongation active carbon filter core.
