A kind of adsorption composite material and preparation method thereof
Technical field
The invention belongs to technical field of composite materials, in particular to a kind of adsorption composite material and preparation method thereof.
Background technique
Along with the high speed development of industrialization and urbanization process, water resource pollution problem has become people and increasingly discusses
Focus, the especially pollution of drinking water, more people are paid close attention to.Chemical organic compounds and heavy metal component in drinking water
Value volume and range of product is all being continuously increased, and the various pathogenic microorganism factors also continuously emerge.The population that China also has more than 60% is drunk
Water does not meet water quality standard for drinking water.Therefore, the substances such as trace contaminant and heavy metal in drinking water are removed to have become
The vital task of water purification.
Currently, Advanced Drinking Water Purification Technology used in the prior art has: UF membrane, ozone oxidation, semiconductor light
The technologies such as catalysis oxidation, absorption.Membrane separation technique has the characteristics that efficient, the simple process etc. that can reconcile is excellent, but due to its membrane aperture
Very small, the ion (including the micro member beneficial to human body) in water almost removes, this water of long-term drinking, to the health of people
It is harmful.In addition, the cost of film is high, contamination resistance is poor, operating pressure is big, the higher deficiency of energy consumption limits its large-scale application.
Although ozone can be reacted with most of Organic substance in water, ozone oxidation is used alone, it is limited to purification of water quality treatment effect.
Some researches show that, ozone oxidations to the chloroform formed in water almost without removal effect, to the heavy metal in water from
Son is acted on without removal.Photocatalysis oxidation technique is a kind of emerging modern water treatment technology, the crowd used in light-catalyzed reaction
In multiple semiconductor catalyst, nano titania particle is rotten due to stable, nontoxic, the anti-chemistry of, property high with catalytic activity and light
The advantages that erosion and become numerous researchers first choice.However since nano-titanium oxide partial size is small, it is easy to run off, later period catalyst
Separation and recycling it is difficult, make it difficult to be widely applied in drink water purifying processing.Research work mostly rests on laboratory
In the stage, the application in water process Practical Project is seldom.Absorption rule is the surface nature and Large ratio surface using adsorbent material
Product carries out enrichment and separation to water pollutant, has the advantages that convenient operation and management and low energy consumption, be always what people studied
Hot spot.The active charcoal of common adsorbent material, expanded graphite, clay mineral, zeolite, hydrotalcite, metal oxide, metal tripolyphosphate
Salt and flyash etc..Adsorbent material has the characteristics that selective absorption, active carbon and expanded graphite to having in water to water pollutant
Machine object adsorption effect is fine, but to less effective heavy metal ion adsorbed in water;The inorganic material such as clay mineral and zeolite are to water
Middle removal of heavy metal ions rate is high, and to some organic matters in water, then possible absorption property is poor.
