Description
Technical field
The present invention relates to the preparation method of a kind of inorganic compound particles for effluent containing heavy metal ions advanced treating, belong to
Technical field of composite materials.
Background technology
Heavy metal ion is a kind of the most very harmful common pollutant, can the most gradually deposit, being good for of impact
Health.The industries such as plating, electronics, metallurgy all can produce a large amount of waste water produced containing heavy metal ion.Adopt in traditional wastewater engineering more
By chemical precipitation method, this method is the most universal and with low cost, but it is inadequate to process the degree of depth, can only process the dense of several ppm
Degree, also has bigger gap from discharge standard.Absorbent charcoal material can advanced treatment for heavy metal ion rapidly, but adsorption capacity is very
Little, it is easy to saturated, therefore ton cost of water treatment is the highest.Ion exchange material such as ion exchange resin, hydroxyapatite, zeolite
Have a preferable effect etc. having turned out the heavy metal ion removed in water for exchange, but subject matter to be exchange velocity low,
Time is long, processes the degree of depth inadequate, does not the most also have the engineer applied of reality.Chelating resin, chitosan by chelating or can have
Machine group complexation reaches the treatment effect of the degree of depth, but due to expensive, the most also could not promote and come.Thus may be used
See, reach the most at lower cost advanced treating effect be during current effluent containing heavy metal ions processes faced one important ask
Topic.
Hydroxyapatite is a kind of inorganic material with ion-exchange capacity, has had a lot of research to use it for removing
Heavy metal ion in water, such as the Chinese invention patent of Publication No. CN101613135A, " one utilizes nanometer hydroxyapatite
The method removing heavy metal ions in sewage " in mention in the waste water containing heavy metal ion addition nanometer hydroxyapatite powder
Can be with heavy-metal ion removal.But simple hydroxyapatite processes for effluent containing heavy metal ions and there is following problem:
1, under powdery hydroxyapatite is only used for the static conditions of laboratory, if be applied in the sewage work of actual flow,
Will not discharge with current, the obstruction current that will not lump pass through.2, stand time oversize, it is generally required to ten several hours with
On.3, processing the degree of depth the most not, in the case of the initial concentration of 60ppm, only reach the clearance of more than 90%, residual concentration is still
There is several ppm, it is impossible to reach advanced treating, the requirement of qualified discharge.
Summary of the invention
For defect of the prior art, it is an object of the invention to provide a kind of for effluent containing heavy metal ions advanced treating
The preparation method of inorganic compound particles, inorganic compound particles prepared by the method for the present invention can the lower cost ground degree of depth be removed
Heavy metal ion in water.
The present invention is achieved by the following technical solutions:
The invention provides the preparation method of a kind of inorganic compound particles for effluent containing heavy metal ions advanced treating, its
Comprise the steps:
After high-purity lignin powder and hydroxyapatite are carried out wet granulation, enter under the oxygen free condition of 950～1100 DEG C
Row sintering, obtains described inorganic compound particles.
Preferably, described high-purity lignin powder is 1:2～9:1 with the weight ratio of hydroxyapatite.
Preferably, the particle diameter of described high Vinsol is 100～300 mesh.
Preferably, the particle diameter of described hydroxyapatite is nanoscale.
Preferably, the operation of described wet granulation is:
To after the most saturated in the sodium hydrate aqueous solution be dissolved in high-purity lignin powder, add hydroxyapatite, after mixing
It is a granulated into the granule of a diameter of 1～2mm, dries.
Preferably, the mass fraction of described sodium hydrate aqueous solution is 1～5%.
Self-constriction adhesion properties when the present invention utilizes high Vinsol to sinter and the ion-exchange capacity of hydroxyapatite
Combine, carry out solid-liquid by lignin dissolution characteristics in sodium hydroxide solution and nanometer hydroxyapatite powder and uniformly mix
Close, by sintering after wet granulation.The physical absorption ability of composite particles is mainly changed into when sintering by high Vinsol
Charcoal the porous charcoal components contribution formed through sodium hydroxide etching pore-creating, ion-exchange capacity then derives from nano hydroxyapatite
Lime stone.
Compared with prior art, the present invention has a following beneficial effect:
1, the ion-exchange capacity of the physical absorption ability of porous charcoal with hydroxyapatite is combined with each other, both overcame
The shortcoming that activated carbon capacity is low, it also avoid the inferior position that the slow degree of depth of hydroxyapatite ion-exchange speed is low, has reached quickly, deeply
The effect of heavy metal ion in the removal water of degree and high power capacity；
2, activated carbon and hydroxyapatite bi-material price are the most relatively low, thus relative chela under same treatment ability condition
Resin and modification of chitosan even depth process material cost and are substantially reduced, and have obvious price advantage.And have more high-strength
Degree and the composite particles of certain size, also meet the Practical Project requirement for material.
