Description
Technical field
The present invention relates to oily waste treatment field, particularly relate to a kind of method removing water oil stain and recovery adsorbent.
Background technology
Along with socioeconomic development, people increasingly 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 oil pollution serious threat.Process oil pollution in industrial and life contaminated water at present and have multiple method, such as machinery absorption method, absorption method, chemical dispersion method, sedimentation, biological degradation method, combustion method.Wherein absorption method is the most commonly used, utilize high polymer absorption greasy dirt to the graphite absorption peeled off from the earliest, arrive Graphene absorption greasy dirt again, research and development through decades, the method absorption is the most ripe, but the absorption method existence that presently, there are is not easily recycled, the problem easily causing secondary pollution, and it is loaded down with trivial details to grasp process, the technology content of needs requires the highest.The most in the open or carrying out in the pond opened wide additionally, skimming is general, this is because use machinery absorption method or absorption method etc. to be required to artificial operation above the water surface, and the pond of opening can cause inevitable air pollution.If able to avoid operation above the water surface, just whole processing procedure can be carried out in closing secret room, the pollution of environment will be preferably minimized.
Find a kind of advantages of good adsorption effect, adsorbent with low cost, and simple to operate, the greasy dirt adsorption method of environmental protection and the recovery method of adsorbent are the problems needing solution at present badly.MoS2Being a kind of typical lamellar compound, in its layer, atom is by the strongest chemical bonds, MoS2In 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 relatively big, is combined by more weak van der Waals interaction between layers.The MoS of existing commercialization2Mostly being powder, diameter is uneven and width and thickness is micron order, and has the strongest adhesion, MoS2Water insoluble and diluted acid, for lipophilic-hydrophobic property, it is not easy to water is carried out secondary pollution；Existing MoS2Use mainly as industrial lubricants, there is the industrial chain of maturation, it is possible to carrying out large batch of production and preparation, price is cheaper compared with Graphene.MoS2More stable, fusing point 1185 DEG C, just can occur slowly to aoxidize at 400 DEG C, generate molybdenum trioxide, it is simple to being heat-treated the greasy dirt separating its absorption.
Summary of the invention
The technical problem to be solved is, overcomes the deficiency and defect mentioned in background above technology, it is provided that a kind of use physical adsorbability strong and nanoscale MoS that specific surface area is big2Powder removes the method for water oil stain, correspondingly provides and collects and reclaim adsorbent MoS below the water surface2The method of powder.
For solving above-mentioned technical problem, the technical scheme that the present invention proposes is that one utilizes MoS2The method of water oil stain removed by adsorbent, comprises the following steps:
(1) dry MoS is weighed2Powder；
(2) MoS that will weigh2Powder spreads the most equably to water oil stain, the MoS spread fertilizer over the fields2Powder is close to greasy dirt, absorption greasy dirt, and progressively collects to oil reservoir centre of surface, and concave downward becomes a groove；
(3) continue to spread fertilizer over the fields the most equably remaining MoS to water oil stain2Powder, until MoS2Greasy dirt is wrapped up by powder, sinks to below the water surface with spherical so that it is roll and gather the low-lying place at the bottom at the bottom；
(4) MoS to be sunk2Stand, solidify, obtain adsorbing sphere, then recycling.
In the method for above-mentioned removing water oil stain, it is preferred that described MoS2In the form of sheets, its width dimensions is micron order to powder, and gauge is nanoscale.The thinnest width dimensions can reach 1 μm, has stronger adsorptivity and high dispersion.
In the method for above-mentioned removing water oil stain, it is preferred that described MoS2Powder is the micron-sized MoS by buying on market2Powder is ultrasonically treated through 1.5 ~ 2h, obtain after vacuum drying.
In the method for above-mentioned removing water oil stain, it is preferred that described vacuum drying temperature is 70 ~ 80 DEG C, the time is 40 ~ 60min.
In the method for above-mentioned removing water oil stain, it is preferred that described dry MoS2 powder oil suction mass ratio (every gram of MoS2Powder can adsorb the quality of own wt water oil stain) it is 1:2 ~ 2.3:1.
In the method for above-mentioned removing water oil stain, it is preferred that it is characterized in that, the time of described standing is more than 14h, it is preferred that time of repose is 14 ~ 60h.
As a total inventive concept, the present invention also provides for a kind of method reclaiming described adsorbent, after above-mentioned method operation, described adsorbing sphere is reclaimed, the concrete operations reclaimed include: by adsorbing sphere washes of absolute alcohol, it is subsequently placed in the resistance furnace under inert environments heating, obtains the MoS of sheet2, grind the MoS obtaining recycling capable of circulation2Powder.MoS after recovery2Powder oil suction efficiency is the 86%～90% of original oil absorption.
In above-mentioned method, it is preferred that described heating-up temperature is 350 ~ 390 DEG C, the time is 6 ~ 7h.
Compared with prior art, it is an advantage of the current invention that:
(1) the nanoscale MoS that the present invention uses2Powder particle width is at micron order, and thickness, at nanoscale, has stronger physical adsorbability and bigger 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 height, 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 processing greasy dirt in industrial and life contaminated water；
(3) present invention lossless recovery adsorbent MoS2Powder, the rate of recovery is up to 90%, simple to operate, it is achieved that resource reclaim, avoids secondary pollution simultaneously；To the MoS reclaimed2Powder carries out secondary oil suction experiment, obtain that oil suction efficiency is original oil absorption 72%～90%, it is achieved that cycling and reutilization；
(4) present invention is collecting the MoS having adsorbed greasy dirt2During powder, can carry out below the water surface, therefore whole process can operation within the enclosed space, it is to avoid the open spaces secondary pollution to air.
In sum, the present invention uses nanoscale MoS2Powder removes greasy dirt and lossless recovery MoS on the water surface2The method of recycling, can be as a kind of novel effective ways processing industrial and life contaminated water oil pollution problem.
