Abstract
The invention discloses a preparation method of a bentonite-loaded copper water treatment material. The preparation method comprises the following steps of: crushing 10-15 g of bentonite to be 20-200 meshes; dispersing in 80-150 ml of water in a reagent bottle with a stopper to prepare suspension; adding CuCl into the suspension, wherein the mole number of CuCl is 70-100 percent of bentonite cation exchange capacity in terms of Cu<+> mole number; charging nitrogen into the reagent bottle from the headspace; jam-packing the stopper; magnetically stirring at room temperature for 24 hours; and finally performing precipitation separation, washing with de-ionized water for three to five times, and drying the solid matter in a vacuum drying box of 60-70 DEG C to obtain the bentonite-loaded copper water treatment material. The bentonite-loaded copper water treatment material is used for treating organic wastewater; cuprous ions are adopted; and compared with copper ions, the exchange capacity of copper can be improved, so that more cuprous ions are loaded between bentonite layers and the catalytic oxidation efficiency is increased.
Description
Technical field
The present invention relates to the synthetic field of material for water treatment, relate in particular to a kind of preparation method who is used to handle the material for water treatment of organic wastewater.
Background technology
China's shortage of water resources, water pollution is on the rise.The organic wastewater with difficult degradation thereby intractability is big, cost is high, is the emphasis of water prevention and cure of pollution always.The processing of high concentration hard-degraded organic waste water is the work that difficulty is bigger.In order to solve the pollution problem that organic wastewater causes effectively, all be devoted to Research on New and exploitation both at home and abroad.The method of handling organic wastewater with difficult degradation thereby at present is a lot, as: chemical oxidization method, solvent extraction, absorption method, photocatalytic oxidation, biochemical treatment process etc.
Oxidizing process is the nearly 20 years sewage disposal new methods that grow up.What adopt at first in the industrial wastewater that oxidizing process handles is the ozone oxidation method of cyanide wastewater.But because single-oxidizer usually has stronger selectivity to organic oxidation; Even some organic matter not worked; And in order to reach certain oxidation effectiveness, often need to use more a large amount of oxidants, cause disposal cost high and be difficult in reality, apply.Therefore, the development trend of chemical oxidization method is mixed oxidization, catalytic oxidation and the oxidation of several kinds of oxidants and the GC-MS of additive method.In these methods, because the interaction of oxidant and the catalytic action of catalyst, its oxidability and reaction rate all are far longer than common oxidizing process, and organic selectivity is significantly reduced.Key is to select suitable catalytic oxidant.
Bentonite be a kind of be the clay rock that essential mineral is formed with the montmorillonite; Montmorillonite is by two one of the tetrahedral si-o film therebetween that connects of top layer silicate minerals of forming of the aluminum oxide octahedral sheet that connects of limit altogether altogether; Monolithic layer in its structure is the very big thin slice of asperratio; Diameter is about 100-200 nm, and thickness is merely 1 nm.The such thin slice of 5-10 layer constitute bigger irregular group by these basic granuleses, thereby bentonite has layer structure through the interlayer cation formation basic granules that combines.Aluminium causes negative electrical charge in the construction unit layer (being layer charge) surplus to silicon and magnesium to the ion exchange meeting that the isomorph of aluminium substitutes in the structure, for reaching the balance of positive and negative charge, needs the cation of some to compensate and is positioned at interlayer region.These cations are with ion bonding force connecting structure elementary layer, and are movable, and its key is more much bigger than molecular link or hydrogen bond by force.Therefore when smectite structure elementary layer internal charge does not reach balance, will come filling by a certain amount of cation in the space between elementary layer, thereby (sun) ion exchange will take place.Montmorillonite since in the broken key, lattice isomorph replace and to be adsorbed on its surperficial humus disassociation etc. former thereby electronegative; Thereby cause combining between lattice layer loose; Meet water and be prone to expand into fragment; The particle decentralization is high, has huge internal surface area and a large amount of exchangeable cations, makes it have good adsorption performance and ion-exchange performance (its cation exchange capacity is about 74 ~ 130 mmol/100g).Bentonite is owing to there is good physical and chemical performance; Can do binding agent, suspending agent, thixotropic agent, stabilizing agent, purification and decoloration agent, casting resin, feed, catalyst etc.; Be widely used in agricultural, light industry and cosmetics, medicine in fields such as chemical industry, oil, environmental protection, nano materials, so bentonite is a kind of broad-spectrum natural minerals.
But naturally occurring sodium bentonite and calcium-base bentonite do not have excellent application performance aspect wastewater treatment, must select suitable treatment process and method synthesis utilization according to the characteristics of waste water." Chemical Engineering and equipment " the 6th phase in 2011 has reported that loaded copper oxide comes catalysis methanol hydrogen manufacturing between bentonite bed; The main reduction that rises; Do not have relevant report but be used for wastewater treatment, cupric oxide load capacity between bentonite bed is lower in addition, can influence the efficient of catalytic oxidation.
Summary of the invention
The objective of the invention is provides a kind of preparation method of alta-mud load copper material for water treatment for overcoming the deficiency of prior art, improves load capacity between bentonite bed, and improves the efficient of catalytic oxidation.
The technical scheme that the present invention adopts is to comprise the steps: 1) 10 ~ 15g bentonite is pulverized is 20 ~ 200 orders, in tool plug reagent bottle, is distributed in 80 ~ 150 ml water, processes suspension; 2) in this suspension, add CuCl, the amount of CuCl is with Cu
+Molal quantity meter, its molal quantity are 70% ~ 100% of bentonite cation exchange capacity, add the back and pour nitrogen at the reagent bottle head space, jam-pack stopper, at room temperature magnetic agitation 24 h; 3) precipitate and separate with washed with de-ionized water 3-5 time, is dried solids and promptly to be got alta-mud load copper material for water treatment in 60 ~ 70 ℃ of vacuum drying chambers.
The invention has the beneficial effects as follows:
1, adopts cuprous ion, compare the exchange capacity that can improve copper with copper ion, make the more cuprous ion of load between bentonite bed.
2, material therefor of the present invention is cheap.China verifies the bentonite reserves at present has more than 1,700,000,000 ton, belongs to the first in the world.
