Abstract
The invention discloses a lignin xanthate bentonite composite ball which is mainly prepared from, by weight, 5-20 parts of lignin xanthate, 90-120 parts of bentonite, 2-12 parts of dispersing agent, 18-45 parts of sodium alginate and 3-15 parts of regulator. According to the lignin xanthate bentonite composite ball, the bentonite and the lignin are natural inorganic mineral adsorbing material and organic adsorbing material respectively, the cost is low, the reserve volume is rich, and some progresses are made in the aspects of treating heavy metal and antibiotic pollutants in waste water. Because the lignin has weak adsorption capacity to the heavy metal, the modified lignin xanthate bentonite is taken as an active matter; the lignin xanthate bentonite and the bentonite are compounded, so that higher adsorption capacity to the heavy metal is realized.
Description
Technical field
The invention belongs to field of composite material preparation, biomass resource field, more particularly to a kind of heavy metal, antibiotic
Sewage has lignin xanthate bentonite composite balls of preferable adsorption capacity and preparation method thereof.
Background technology
In China, metal plating, process hides, dyestuff, dig up mine, papermaking and some other chemical industry achieve quick sending out
Exhibition, but generate in these industrial processes containing the substantial amounts of waste water containing heavy metal ion (such as mercury, zinc, lead
Deng), these waste water are also just directly or indirectly discharged without the effective process of sewage department without the monitoring of environment monitoring department
To in environment, serious water pollution problems is caused.Because these heavy metal ion in water cannot be voluntarily in biotic environment
Decomposition and conversion, will eventually be entered in human body body by the effect of food chain, cause uncomfortable people, poisoning or even cause
Cancer, the serious body harm for endangering the mankind of heavy metal ion.
Every year, antibiotic is used the substantial amounts of production of China is simultaneously also substantial amounts of, and yield, consumption occupy world's first.
At present, for the use of antibiotic is also without strict limit standard, the antibiosis in people's use, for animals and pharmaceuticals industry production waste water
If element is just directly entered the pollution that can equally cause water body in water without effective process indirectly.The a large amount of of antibiotic make
Obtaining the resistance to the action of a drug of human body pathogen strengthens, and the immunity for giving people body brings negative effect, can be inhaled by body into after human body
Receive, a series of metabolic process of small part Jing generates inactive metabolite, the action time and metabolism time of antibiotic compared with
Long, for the antibiotic for entering water environment, it still has biologically active, and can further form mother in the environment
Body.Remaining antibiotic can cause the Soil Microorganism resistance to the action of a drug to strengthen in soil, precipitation, gravitational settling and other one
A little approach can cause antibiotic to enter in water body, if people's class reference these contain the water of antibiotic, can cause it is uncomfortable very
To some other diseases.Antibiotic is the another kind of important pollution sources in water pollution, and the water pollution problems of initiation already becomes
Obtain extremely severe.
Lignin also known as lignin, are one of main components of lignocellulose biomass, are storage capacity second on the earth
Biomass resource.The annual paper-making industry in the whole world produces 50,000,000 tons of lignin, but the lignin less than 10% is utilized.It is wooden
Plain complex structure, not yet known to the mankind, structure is mainly macromolecular group to its concrete structure, mainly contains lignum-vitae base junction
The logical basic structure seen of 3 kinds of structure, lilac based structures and p-hydroxyphenyl structure.Lignin contains phenolic hydroxyl group, alcoholic hydroxyl, carbonyl
The functional groups such as base, carboxyl and methoxyl group, this has in terms of showing heavy metal of the lignin as low-cost sorbent in eliminating water is gone
Great potentiality.But lignin is three-dimensional non-linearity macromolecular compound, it is easy to form intermolecular hydrogen bonding, make it can not
Launch in water and be intertwined, form stable flocculate.
Bentonite is the nonmetallic minerals with montmorillonite as main component, is called bentonite, bentonite or swelling rock, due to
There are some cations, such as K, Na, Mg in the layer structure of montmorillonite, the effect of these cations and montmorillonite is not sacrifices consisting of an ox, a sheep and a pig
Gu, easily by other cation exchanges, thus with certain adsorption capacity.But bentonite hydrophily is strong, there is height in water
Expansion, it is easily occupied between layers by hydrone and hydrated ion so as to be difficult to and the heavy metal ion and antibiosis in sewage
Plain pollutant is fully contacted, and has had a strong impact on its absorption property.
Conventional powder shape adsorbent easily disperses in water, processes and is susceptible to be lost in now during the pollutant in waste water
As, settling velocity is slow, to process be difficult after waste water and separate with water body, adsorbed and be difficult to recycle and reuse after pollutant,
Secondary pollution is produced in water.At present, in the correlative study of adsorbent, by being fixed of adsorbent improving its rate of recovery
With solve separation of solid and liquid a difficult problem become study hotspot, compared with powdered form adsorbent, spherical adsorbent have good machinery,
Mass transfer diffusion, and be easily recycled and recycle, application prospect is boundless in terms of water pollution is processed.
The information for being disclosed in the background section is merely intended to increase the understanding of the general background to the present invention, and should not
When the prior art for being considered to recognize or imply in any form the information structure well known to persons skilled in the art.
