Abstract
The invention relates to ceramic filter materials and particularly relates to an attapulgite ceramic filter material for water treatment. The specific surface area of attapulgite is increased by adding an agglomerant and an adhesive and calcinating, so that the attapulgite is high in adsorption capability and is increasingly taken seriously in waste water treatment and the modified attapulgite has wide uses in waste water treatment. The attapulgite is a water-containing magnesium-rich aluminosilicate clay mineral having a layered chain structure. By addition of the agglomerant and the adhesive and calcination, attapulgite crystals are hairy or fibrous, are rod-like or needle like under an electron microscope, are white, grey, light green or light brown, and are fibrous under an atomic force microscope. The inside of the attapulgite is provided with a plurality of porous channels and the cross section of the porous channels is about 0.38 nm*0.63 nm. The attapulgite ceramic filter material is particularly suitable for water treatment.
Description
Technical field
The present invention relates to ceramic filter material, particularly a kind of Attapulgite water treatment ceramic filter material.
Background technology
Absorption is one of common method in sewage disposal, and selecting of sorbing material is the key adopting this technology.Though particulate adsorbent material energy Simplified flowsheet, effectively solves recovery problem, also there is many difficulties in actual applications.Therefore, select suitable solidifying agent, binding agent and pore-forming material, strengthen the granulation research of clay mineral, solve solid-liquid separation problem, find suitable renovation process, realize the recycling of sorbent material, reduce costs and become practical application problem demanding prompt solution.
Do not have a kind of Attapulgite water treatment filter material to promote the use of at present, Attapulgite ceramic ceramic filter material has wide market.Play increasing effect in raising adsorption efficiency, reduction absorption cost and saving source side face, become very rising type material.
Summary of the invention
The invention provides a kind of low cost, long lifetime, not easily form secondary pollution and the Attapulgite water treatment ceramic filter material that can reuse.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Attapulgite water treatment ceramic filter material, comprises the steps:
A, acidifying
Take attapulgite clay as raw material, attapulgite clay, water and sulfuric acid are prepared by weight, attapulgite clay 45-65 part, water 35-50 part, massfraction 98% sulfuric acid 0.5-2 part, massfraction 98% sulfuric acid is diluted in water, be sprayed on attapulgite clay after sulfuric acid dilution, stack 24-48h after stirring, carry out pulverization process, grinding particle size 180-200 order;
B, batching
The attapulgite clay pulverized, agglutinant, binding agent, water are prepared according to weight part, attapulgite clay 65-85 part of pulverizing, agglutinant 2-5 part, binding agent 5-15 part, and water 13-15 part, is uniformly mixed rear standing 5-15h;
C, granulation
Compound sends into the pellet being processed into 1.0-4.0mm diameter in tablets press, leaves standstill 24-48h;
D, roasting
By pellet through 450-550 DEG C of roasting 1-2h, naturally cool to normal temperature after pellet dehydrating and curing and obtain finished product.
Also comprise step e finished product is sieved, be divided into 1.0-2.0mm, 2.0-3.0mm, 3.0-4.0mm tri-kinds of specifications.
In described steps A, ferric oxide powder selected by agglutinant.
In described steps A, the one or more combination in the materials such as starch, methylcellulose gum, paraffin, glycerine, natural gum and polyvinyl alcohol selected by binding agent.
Beneficial effect of the present invention is:
The present invention is by after attapulgite clay acidification, add agglutinant and binding agent to carry out roasting and form attapulgite based ceramic adsorbent articles, this kind of attapulgite based ceramic adsorbent articles controlled within 550 DEG C by burning curing molding temperature, guarantee not destroy the crystal habit of attapulgite and do not change its physicochemical property; The main raw material chemical Composition Control of attapulgite based ceramic adsorbent articles is after testing: SiO
2=56%, Al
2o
3=14%, Fe
2o
3=6%, CaO=10%, Na
2o=1.5%, MgO=10%, SO
3=0.5%, other compositions 2%.By adding agglutinant and binding agent roasting, attapulgite specific surface area being increased, has stronger adsorptive power, cause more and more many attention in the treatment of waste water, modified attapulgite purposes is in the treatment of waste water wider.Attapulgite be a kind of layer of chain-like structure containing Shuifu County's zeopan clay mineral.Add agglutinant and binding agent roasting makes attapulgite crystal be hair-like or fibrous, under an electron microscope in long column shape or needle-like, white, grey, light green or light brown, be fibrous under atom mechanics microscope; There is a lot of duct attapulgite inside, the about 0.38nm × 0.63nm in cross section, duct.Be especially suitable for use as water treatment.
Above-mentioned materials can be widely used in the numerous areas of the industrial sectors such as petrochemical complex, drilling well, agricultural, medical science, building, nuclear industry, environmental protection, silicate industry; Special in field of Environment Protection, it is mainly used in process trade effluent, purifying air, deodorant for refregerator, preventing and fixing sand, water purification, can process heavy metal wastewater thereby efficiently, effectively removes the rich nutritive material in waste water.
The present invention is directed to water treatment sorbing material, developing low-cost, long lifetime, not easily form secondary pollution and the Attapulgite water treatment ceramic filter material that can reuse.There is following aspect feature:
1. the attapulgite selecting resource extensive, cheap is raw material, auxiliary agent method and high-temperature roasting method are added in comprehensive employing, compensate for single haydite void content adopting high-temperature roasting to prepare low, single employing adds the lower realistic situation of auxiliary agent intensity, develops that void content is high, volume density is little and the environmental protection type honeycomb shape haydite sorbent material of recoverable;
2. Attapulgite soil matrix haydite is a kind of efficient, reproducible sorbing material, the gas expansion that the liquid phase produced under utilizing its proper temperature and oxidation of coal produce and make porous ceramic grain;
3. leca filtrate had both been applicable to cities and towns and industrial water supply process, was also adapted to biochemistry (oil removing, deironing, the demanganization etc.) process of metallurgy, oil, chemical industry, textile waste.Leca filtrate is not only applicable to various types of general filter chamber, fast filter chamber, valveless filtering pool, siphon filter, portable flushing cover and gravity filter, and is the best filler of various efficient purifier, small towns small-sized water purifier water conditioning.The advantage of leca filtrate is: light weight, loose capacity are little, specific surface area is large, high adsorption capacity, porosity are high, stable chemical performance, not containing being harmful to HUMAN HEALTH and industrial oxious component.
4. due to honeycomb ceramic filter material have that surface-area is large, anti-microbial property good, resistance to rapid heat cycle, resistance to chemical attack, wear-resistant, physical strength is high and regenerate the advantages such as easy, water purification process and organic solution.
Before, the ceramic grain filter for filtration, purification is through that granulation process produces, although have micropore on haydite, but haydite is solid shape, thus the tap density of this haydite is comparatively large, and water treatment filter material filtration area is little, filter effect is low, water treatment construction cost and running cost high.Cellular ceramic grain filter entity portion has the netted hole of honeycomb, its filtrate tap density is less, Water treatment filtration area is larger, the oxygen supply of haydite surface bacteria is more abundant, active increase, microorganism is more, good filtration effect, and tower heavy burden load reduces, the reduction corresponding to running cost of water treatment construction cost.
