Description

Utilize MoS 2sorbent material removes the method for water oil stain and the recovery method of sorbent material
Technical field
The present invention relates to oily waste treatment field, particularly relate to a kind of method removed water oil stain and reclaim sorbent material.
Background technology
Along with socioeconomic development, people more and more pay close attention to the problem of environmental pollution that global industry brings.Wherein in industrial and life contaminated water, the living environment of people in pollution by oil serious threat.In current process industrial and life contaminated water, pollution by oil has multiple method, as mechanical absorption method, absorption method, chemical dispersion method, settling process, biological degradation method, combustion method.Wherein absorption method is the most conventional, greasy dirt is adsorbed to the graphite absorption of peeling off from utilizing superpolymer the earliest, arrive Graphene absorption greasy dirt again, through the researchdevelopment of decades, this method absorption is very ripe, but the absorption method existence existed at present is not easily reclaimed, and easily causes the problem of secondary pollution, and it is loaded down with trivial details to grasp process, the technology content of needs requires also higher.In addition, skimming generally carries out in the open or in the pond opened wide, this is because adopt mechanical absorption method or absorption method etc. all to need artificial operation above the water surface, and the pond of opening can cause inevitable atmospheric pollution.If operation above the water surface can be avoided, just whole treating processes can be carried out in closed secret room, will drop to minimum to the pollution of environment.
Find a kind of advantages of good adsorption effect, sorbent material with low cost, and simple to operate, the greasy dirt adsorption method of environmental protection and the recovery method of sorbent material are the problems needing solution at present badly.MoS 2be a kind of typical lamellar compound, in its layer, atom is by very strong chemical bonds, MoS 2in each molybdenum atom be that triangular prism column encloses by six sulphur atoms be that Mo-S faceted pebble is quite a lot of, specific surface area is comparatively large, is combined between layers by more weak van der Waals interaction.The MoS of existing commercialization 2mostly be Powdered, diameter is uneven and width and thickness is micron order, and has very strong adhesive power, MoS 2water insoluble and diluted acid, is lipophilic-hydrophobic property, is not easy to carry out secondary pollution to water; Existing MoS 2use mainly as industrial lubricants, had ripe industrial chain, can carry out large batch of production and preparation, price is cheaper compared with Graphene.MoS 2more stable, just can there is slow oxidation at 400 DEG C in fusing point 1185 DEG C, generates molybdic oxide, is convenient to the greasy dirt being separated its absorption with thermal treatment.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency and defect mentioned in above background technology, provides a kind of and adopts physical adsorbability strong and the nano level MoS that specific surface area is large 2powder removes the method for water oil stain, and also corresponding being provided in be collected below the water surface and to reclaim sorbent material MoS 2the method of powder.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is that one utilizes MoS 2the method of water oil stain removed by sorbent material, comprises the following steps:
(1) dry MoS is taken 2powder;
(2) MoS will taken 2powder slowly spreads equably to water oil stain, the MoS spread fertilizer over the fields 2powder is close to greasy dirt, absorption greasy dirt, and progressively collects to oil reservoir centre of surface, becomes a groove to lower recess;
(3) continue slowly to spread fertilizer over the fields remaining MoS equably to water oil stain 2powder, until MoS 2greasy dirt wraps up by powder, sinks to below the water surface with spherical, makes it roll at the bottom and gathers water-bed low-lying place;
(4) MoS to be sunk 2leave standstill, solidify, obtain adsorbing sphere, then recycling.
In the method for above-mentioned removing water oil stain, preferably, described MoS 2in the form of sheets, its width dimensions is micron order to powder, and gauge is nano level.The thinnest width dimensions can reach 1 μm, has stronger adsorptivity and high dispersion.
In the method for above-mentioned removing water oil stain, preferably, described MoS 2powder is the micron-sized MoS by market is bought 2powder obtains after 1.5 ~ 2h supersound process, vacuum-drying.
In the method for above-mentioned removing water oil stain, preferably, described vacuum drying temperature is 70 ~ 80 DEG C, and the time is 40 ~ 60min.
In the method for above-mentioned removing water oil stain, preferably, MoS2 powder oil suction mass ratio (every gram of MoS of described drying 2powder can adsorb the quality of own wt water oil stain) be 1:2 ~ 2.3:1.
In the method for above-mentioned removing water oil stain, preferably, it is characterized in that, the described standing time is more than 14h, and preferably, time of repose is 14 ~ 60h.
As a total inventive concept, the present invention also provides a kind of method reclaiming described sorbent material, after the operation of above-mentioned method, described adsorbing sphere is reclaimed, the concrete operations of reclaiming comprise: by adsorbing sphere washes of absolute alcohol, then the resistance furnace be placed under inert environments heats, and obtains the MoS of sheet 2, grinding obtains the MoS of recycling capable of circulation 2powder.MoS after recovery 2powder oil suction efficiency is 86% ~ 90% of original oil absorption.
In above-mentioned method, preferably, described Heating temperature is 350 ~ 390 DEG C, and the time is 6 ~ 7h.
Compared with prior art, the invention has the advantages that:
(1) the nano level MoS of the present invention's employing 2powder particle width is at micron order, and thickness, at nano level, has stronger physical adsorbability and larger specific surface area;
(2) absorption method of the present invention removes greasy dirt good stability, simple, with low cost, solve the problems such as chemical method cost is high, secondary environmental pollution, compensate for the defect that in absorption method, oil-absorbing resin preparation is complicated simultaneously, and ensure effectively to remove greasy dirt, may be used on greasy dirt in process industrial and life contaminated water;
(3) the present invention is harmless reclaims sorbent material MoS 2powder, the rate of recovery is up to 90%, simple to operate, achieves resource reclaim, avoids secondary pollution simultaneously; To the MoS reclaimed 2powder carries out secondary oil suction experiment, and obtain that oil suction efficiency is original oil absorption 72% ~ 90%, achieve cycling and reutilization;
(4) the present invention has adsorbed the MoS of greasy dirt in collection 2during powder, can carry out below the water surface, therefore whole process can operation within the enclosed space, avoids the secondary pollution of open spaces to air.
In sum, the present invention adopts nano level MoS 2powder removes greasy dirt and harmless recovery MoS on the water surface 2the method of recycling, can as a kind of novel effective ways processing industrial and life contaminated water pollution by oil problem.
