Description
Technical field
The present invention relates to a kind of methods for drawing organic solvent from water body using montmorillonite.
Background technique
Organic solvent is widely used in the industries such as paint, coating, printing, medicine, papermaking, these solvents flow into meeting in water
Water body is polluted, brings grave danger to environmental and human health impacts, therefore, the organic solvent in tail water is adsorbed into tool
Have very important significance.There are many ways to recycling organic solvent from water at present, such as absorption method, will be in water by active carbon
Organic matter adsorb, in disclosed paper (and it is refined, organic solvent regenerated carbon is utilized in Treatment of Coking Effluent
Study the Taiyuan [D] .2010., University Of Shanxi) He Binbin et al. using organic solvent to the active carbon after absorption coking wastewater saturation
It is regenerated, the selection of solvent, regeneration effect and influence factor has been carried out compared with systematic research, but active carbon is utilized to remove
Organic solvent higher cost in water body, the carbon dust being dispersed in water are difficult sedimentation and remove.There are also atmospheric distillation, extracting rectifyings
Technology, salt distillation technology etc., the investment of these methods is big, and energy consumption is high.(Yang Jian, Wang Shifen, the Guo Changhong in disclosed paper
Acclimation sludge handles organic solvent waste water research [J] environment and exploitation, 14 (1) 1999:12-16), the biodegrade such as Yang Jian
Method handles the organic matter in water, specially utilizes the isopropanol in the microorganism decomposition waste liquid after domestication culture.But this method
The decomposition rate for handling isopropanol in water is slow, and tiny microorganism is relatively difficult to recycle, and invalid to the solvent other than isopropanol.
Summary of the invention
The technical problem to be solved by the present invention is to aiming at the above shortcomings existing in the prior art, provide a kind of utilize to cover
The method of organic solvent in de- stone adsorbed water body realizes the height to the organic solvent being dispersed in water with both economical method
Effect separation.
In order to solve the above technical problems, present invention provide the technical scheme that
There is provided a kind of method that organic solvent is drawn from water body, comprising the following steps: first seal montmorillonite mineral powder
It in the container of constant volume and is compacted, makes montmorillonite mineral powder full of whole container, the container at least one side is by energy
It is enough sealed through the film of small molecule, the film can seep water and organic solvent, but cannot penetrate montmorillonite mineral powder, then
One end that container can permeate water and organic solvent is immersed in the water body containing organic solvent, standing adsorption is until montmorillonite mine
Until object powder soaks, then container is taken out, terminates suction process.
According to the above scheme, montmorillonite mineral powder size≤50 μm, the na-montmorillonite that purity is 95% or more.
According to the above scheme, the organic solvent is water-soluble semi-polarity small molecule solvent.
According to the above scheme, the organic solvent is alcohols.
Preferably, organic solvent is one of methanol, ethyl alcohol, propyl alcohol, isopropanol.
According to the above scheme, the standing adsorption time is 10-30min.
The present invention is based on montmorillonite powder, and water can not be absorbed in non-bloating situation, but can absorb the original of organic solvent
Reason, montmorillonite powder compaction, which is encapsulated in the container of constant volume, prevents montmorillonite volume expansion, then immerses in water body and can incite somebody to action
Organic matter in water body absorbs out, but not adsorbed water molecule, has selectivity.
The beneficial effects of the present invention are: organic matter is absorbed from water using the method for the present invention, solve montmorillonite because
Absorb water the problem for blocking interlayer, causing adsorption efficiency low；In addition, the montmorillonite powder of encapsulation in a reservoir will not be distributed to water
Secondary pollution is caused to water body in solution, and because montmorillonite does not absorb moisture, only absorbs organic solvent, does not absorb water
Montmorillonite it is dry after will not agglomerate, by the way that the dry montmorillonite powder that may be implemented of montmorillonite to be recycled, operation is also compared
It is convenient.
Detailed description of the invention
Fig. 1 is described in the embodiment of the present invention 1 for encapsulating the schematic diagram of the container of montmorillonite mineral powder；
Fig. 2 is the matter that embodiment 1 absorbs organic solvent using montmorillonite mineral powder from the liquid of different volumes score
Spirogram.
Specific embodiment
Technical solution in order to enable those skilled in the art to better understand the present invention, with reference to the accompanying drawing to the present invention make into
One step detailed description.
Embodiment 1
Organic solvent is drawn from water body using montmorillonite mineral powder, steps are as follows:
First take 5g montmorillonite mineral powder (purity is greater than 95% na-montmorillonite powder, and average grain diameter is 6.02 μm) pressure
In fact in the steel drum of constant volume, Fig. 1 is described in the present embodiment for encapsulating the schematic diagram of the container of montmorillonite mineral powder；Such as
Shown in Fig. 1, which includes cylindrical container and the interior piston mutually fitted therewith set, and piston is equipped with connecting rod and threaded rod,
Threaded rod is used to adjust the position of piston, is also equipped with upper cover in connecting rod, for sealing steel drum, steel drum bottom is sealed by filter paper
Dress, which can be through small molecules such as organic solvent and water, but cannot penetrate montmorillonite mineral powder.It is packed into and covers into steel drum
Lower piston is pressed by rotating threaded rod after de- stone mineral dust, piston upper has hole, can when piston moves downward incite somebody to action
Air discharge, and montmorillonite mineral powder is compacted.It can be by steel drum upper suspension in Kruss-K-100 balance by connecting rod
On.The lower part filter paper part of steel drum is immersed in the water body dissolved with organic solvent, balance can be every 5 seconds to suspension steel drum
Reading, to record the quality of the organic solvent of absorption.
Using isopropyl alcohol and water as raw material, configuration debris-containing clay slope is respectively 0%, 10%, 20%, 30%, 40%,
50%, 60%, 70%, 80%, 90%, steel drum low side is immersed liquid under conditions of temperature is 25 DEG C by 100% liquid
Middle 5min, measurement absorb the quality of liquid.Fig. 2 is to be inhaled from the liquid of these different volumes scores using montmorillonite mineral powder
Receive the Quality Map of organic solvent.As shown in Fig. 2, montmorillonite mineral powder absorbs the matter that 5min absorbs water in 100% pure water
Amount be 0.0858g, debris-containing clay slope be 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% it is different
In propanol solution, quality incrementss are respectively 0.4994g, 0.4144g, 0.3312g after montmorillonite mineral absorbs 5min,
Therefore 0.2989g, 0.1895g, 0.1832g, 0.1719g, 0.1318g, 0.0879g after immersing 5min in water body, are covered de-
The quality of stone mineral absorption organic solvent is that the quality of absorption organic solvent subtracts the quality that water is absorbed in 100% pure water,
Respectively 0.4136g, 0.3286g, 0.2454g, 0.2131g, 0.1037g, 0.0974g, 0.0861g, 0.046g, 0.021g.
Organic solvent is absorbed from aqueous solution using this method, the concentration range for being absorbed solution is wide in range.
The isopropanol being adsorbed between montmorillonite layer using this method, under the conditions of 60 DEG C, it is de- that drying can be completed in 15min
It is attached.Montmorillonite mineral powder can be recycled convenient and efficient.
Above-described embodiment describes the embodiments of the present invention in detail and essential implementation, is not to protection model of the invention
