Abstract
The invention provides a modified bentonite composite purifier which has strong adsorption capacity for printing and dyeing and oily water and a preparation method of the modified bentonite composite purifier. The preparation method comprises the following steps of firstly adding a certain amount of silane or titanate coupling reagent, alkyl ammonium salt and water into bentonite for modifying, adding activated carbon powder, stirring and compositing, separating, drying and smashing obtained solid, thus obtaining the modified bentonite composite purifier. The coupling modified bentonite composite purifier prepared by the invention has the strong adsorption, decoloration and deodorization capacities, and is suitable for treatment of organic sewage in printing and dyeing as well as oils.
Description
Technical field
The invention belongs to bentonite modified, compound powder preparation field, particularly a kind of organic matter sewage to printing and dyeing, oils etc. has modified alta-mud composite water purifying agent of better absorption, decolouring, deodorizing capability and preparation method thereof.
Background technology
Bentonite is large clay mineral products that resource distribution is extensive, purposes is numerous, is to be called the nonmetallic ore kind with " thousand kinds of purposes ".Bentonite product after processing has been widely used in various trade effluents, sanitary sewage disposal field.According to the difference of sewage character, can be divided into organic sewage, the large class of inorganic metal ion sewage two; Wherein organic sewage is subdivided into again the sewage such as printing and dyeing, oil product, papermaking.Organic sewage is processed to the Bentonite Clean Water Reagent of use, at present main preparation technology adopts inorganic or organic-pillared dose of alone or coupling to support the interlamellar spacing of the contained montmorillonite of large bentonite, is beneficial to absorption, precipitation and separation to large molecular organic pollutants; Used organic-pillared dose is mainly softex kw, but the alkylammonium valency of bromination is high, settling velocity mud water capacity slow, that produce is large than the high sludge volume that makes, and bromide ion to the existence of microorganism and multiply ineffective, if can cause counter productive to follow-up further biological cleaning.
As Chinese invention patent ZL200610135156.6, ZL200610135157.0, ZL200610135158.5 adopt respectively functionally similar inorganic NiTi/ferrotitanium/iron silicon and organic softex kw as composite pillared dose, although the interlamellar spacing after pillared is larger, better to the Adsorption of Organic effect, but pillared montmorillonite is the structure of single particulate, particulate sinking speed after adsorption treatment is still slower, and organic-pillared dose of adopting to adopt be subsequent treatment to be had to the softex kw of certain negative effect.
Coupling agent is that to take silicon, titanium, aluminium, zirconium, chromium be the core ion to a large class, the organic compound that connects respectively 3 or 4 or 6 organic groups, the selection of organic group is two classes again, one class is the group with close organic matter or tool respond active function groups, as oxygen base, sulfydryl, ethyoxyl, epoxy radicals, amide groups, aminopropyl etc., another kind of is the alkoxyl, halogen, acyloxy etc. that band can be hydrolyzed, and the product after hydrolysis can be in the hydroxyl reaction of inorganic powder surface; The comprehensive function result of this two classes group is that the organic and inorganic thing (group) in system is linked to be to volume and the large aggregation of quality.
Coupling agent modified powder is mainly used in the matrix systems such as the same plastics of modified filler, rubber, fluid sealant at present, and in the preparation of modified alta-mud water purification agent, application has no application report.The effect of the systems such as plastics, rubber, fluid sealant that coexist is similar, and in the organic sewage purified treatment, coupling agent also can make organic dirt with the better combination of cleanser, and accelerates solids precipitation, separation.Although the kind of coupling agent is more, the water purification system has higher requirements to the stability of group in water of its coupling agent, thereby spendable coupling agent kind is also limited.
Summary of the invention
The object of the invention is to overcome the shortcoming of the slow and bromination alkylammonium subsequent treatment counter productive of single particulate adsorption particle settling velocity, providing a kind of makes the coupling of single particulate adsorption particle to accelerate settling velocity with coupling agent, and the pillared effect of coupling stronger, be more conducive to bentonite containing the montmorillonite lamella dissociate, to the better chlorination alkylammonium of subsequent biological treatment modified synergic bentonite, and composite activated carbon further improves the composite water purifying agent of clean-up effect.
Another object of the present invention is to provide the preparation method of composite water purifying agent.
The preparation method of modified alta-mud composite water purifying agent of the present invention, to add the silane coupler of 0.1 ~ 1.0 mass parts or the titanate coupling agent of 0.5 ~ 1.5 mass parts, the alkylammonium salt of 1 ~ 5 mass parts in the bentonite of 100 mass parts, be uniformly mixed the water that backward mixed system adds 70 ℃ ~ 90 ℃, the solid-liquid mass volume ratio of the hierarchy of control is 1/2 ~ 1/5, stirring at normal temperature 10 ~ 30min; Add again the activated carbon powder of 0.2 ~ 2.0 mass parts to mixed system, continue to stir 10min; The mixed liquor Separation of Solid and Liquid, wet sample is in 100 ℃ ~ 110 ℃ oven dry, and dried particulate material is ground into granularity 100 orders ~ 200 purpose powder and get final product.
The coupling agent that the present invention adopts is any in vinyltrimethoxy silane, aminopropyl triethoxysilane, glycidoxy-propyltrimethoxy silane, Di(dioctylpyrophosphato) ethylene titanate.
The alkylammonium salt that the present invention adopts is OTAC, hexadecyltrimethylammonium chloride or INCROQUAT TMC-80.
Its smectite content of bentonite that the present invention adopts >=50%, cation exchange total amount 50-100mmol/100g, smectite content is higher, and effect is better.
Modified alta-mud composite water purifying agent prepared by preparation method of the present invention.
beneficial effect of the present invention
Adopt the present invention of foregoing invention content technologies scheme, due to silane used or titanate coupling agent can with the hydroxyl generation chemical reaction of bentonite containing mineral surfaces, increase the contained mineral of bentonite to being required to process the compatibility of organic dirt, and can make the single particulate coupling after absorption become the aggregation that volume is larger, to accelerate deposition of dirt, separating rate; And stronger by pillared effect, to the better chlorination alkylammonium of subsequent biological treatment modified alta-mud.A whole set of technique has that the material composition utilization is reasonable, wastewater purification efficiency is high and is conducive to the characteristics of follow-up further biological treatment etc.
