Description
Technical field
The present invention relates to water treatment agent field, be specifically related to a kind of with natural zeolite and natural fiber inorganic mineral water treatment agent that is primary raw material and preparation method thereof.
Background technology
The chemical agent that water treatment agent is water for industrial use, must use in domestic water, wastewater treatment process.The use of these chemical agents, makes the quality requirement that water reaches certain.Its Main Function is the formation controlling incrustation scale, mud, reduces foam, reduces the corrosion to material contact with water, and except the suspended solid in anhydrating and noxious material, deodorizing, decolouring, soften, stabilizing water quality and desalinization etc.The material base that the development of water treatment field itself relies on also is taken from environment, its many product also has many requirements not meeting environmental protection, as medicament or the formulation product of poisonous, high phosphorus, heavy metal, the current demand that technically can't meet water treatment, therefore, water treatment field itself is also faced with the problem such as demand of technological innovation, development, develop low toxicity, even nontoxic with eco-friendly Green Water treatment product and rationally, economic, safe Green Water treatment process, be the active demand of current water treatment field.And zeolite has the performances such as adsorptivity, ion exchangeable, catalysis and acidproof heat-proof, can be used as adsorbent, ion-exchanger and catalyst, for aspects such as sewage disposals, there is market application foreground widely.
Natural zeolite surface silicon oxide structure has extremely strong hydrophily, and the hydrolysis of structural outer cation easily, cause the performance extreme difference of natural zeolite adsorb organic compound, and silicon-aluminum structure itself is electronegative, therefore natural zeolite is difficult to remove the anionic pollutant in water.Therefore, modification is carried out to natural zeolite, improve its adsorption capacity to organic matter and anion, natural zeolite can be made more to be widely used in water treatment field natural zeolite through modification, its porosity and surface-active can be significantly improved, improve absorption property, ion-exchange performance and exchange capacity etc., thus improve its use value.Modified zeolite comprises wide range, from through simple ion-exchange treatment until the complete avalanche of structure and the product obtained all belongs to modified zeolite scope.
Porous zeolite material is the crystalline zeolite containing enriching porous, not only remain the excellent acidity of zeolitic material and hydrothermal stability, and improve it to macromolecular absorption and diffusion due to the introducing of new bore, particularly relating in macromolecular catalytic reaction at catalytic field is the material that there is application prospect pole.Early stage porous zeolite synthetic method mainly uses post processing, comprises hydrothermal treatment consists, acid treatment or alkali treatment.The use of template in recent years becomes the main method of synthesizing porous zeolite, mainly comprises mesoporous carbon template, high molecular polymer, organosilan and nano-inorganic substance etc.But the shortcomings such as existing template is big for environment pollution, cost is high, crystallization time is long, should not widely use.
Chinese Patent Application No. 201210382889.5,201210010532.4 and 201310414937.9, by zeolite and other blend Coagulation and Adsorption or metal-modified, improve absorption and sedimentation effect, adding of metallics can change water quality activity, but be sorbent usedly natural materials, absorption property is limited, and metal-modified rear absorption object is single, can only partial adsorbates to the pollutant such as organic matter, metal, and the adding of metal active material, can cause the secondary pollution to water body, the Treatment of Sludge trouble after absorption, easily causes secondary pollution to environment.
Chinese Patent Application No. 201310543704.9 and 200810143851.6, by zeolite through alkali treatment and surface modification, but the adsorptive selectivity had of modifier, can only adsorb certain or certain pollutant, so do not have a significant effect to this inorganic agent of process of complicated component sewage.
Chinese Patent Application No. 201210020674.9 and 201110321285.5, by zeolite through alkali treatment, microwave treatment, acid treatment etc., zeolite effective aperture is increased and promotes the generation of meso-hole structure, but inorganic agent used is the highly basic strong acid such as NaOH, lithium hydroxide, potassium hydroxide, sulfuric acid, nitric acid, have higher risk, and discharge of wastewater easily causes the secondary pollution of water quality, air etc. in large-scale production.
Chinese Patent Application No. 200810080287.8 and 200810080287.8, uses template modified zeolite, makes modified zeolite be highly ordered porous materials, but template is to mostly being non-green auxiliary agent, easily to environment, in manufacture process, crystallization time is long, makes production cost higher.
