Description
Technical field
The invention belongs to Material Fields, and in particular to one kind wire rod of 3D printing containing coffee grounds and preparation method thereof.
Background technique
China's total water resources are although more, but quantity per capita is not enriched.With industrial development, water pollution phenomenon is increasingly
Seriously, wherein the most outstanding pollute for Dying Wastewater Treatment & and heavy metal wastewater thereby, it is seriously deficient that this more results in water resource,
Environmental pollution is got worse.Dyestuff majority is extremely stable, into environment waters after be difficult to natural degradation, cause Polluted water area color
Degree increases, and influences incident ray amount, and then influence the normal activities of aquatic animals and plants, destroys the ecological balance of water body,
More seriously dyestuff is mostly noxious material, has carcinogenic teratogenic effect, is discharged into environment to the mankind and other biological
Health, which is constituted, greatly to threaten.The waste water containing plurality of heavy metal that the industries such as plating, Treatment of Metal Surface, printed circuit board generate
It is discharged into various natural waters and seriously polluted river, river, lake, pool and body of groundwater, pass through Accumulative effect, harm
Major biology of nature destroys the ecological balance.Therefore processing dyeing waste water and heavy metal wastewater thereby are very urgent.Handle at present this two
Big waste water mainly includes physical treatment (absorption, membrane separation technique, ultrasonic gas vibration method, high-energy physics method and extraction etc.), chemistry
Handle (chemical oxidization method, electrochemical process and photochemical oxidation method etc.) and bioanalysis (bioflocculation and biological adsorption), but these
There are input cost height, secondary treatment difficulties to cause the drawbacks such as secondary pollution of water, period length for method.
Coffee & tea belongs to one of three big beverages, is favored by the majority of consumers.2016/2017 annual global coffee yield
Nearly 9,400,000 tons, yield steadily rise in recent years.And every production 1kg coffee will generate 0.9kg coffee grounds.In coffee grounds
Containing organic matters such as fatty acid, lignin, cellulose and hemicelluloses, it is considered as the sustainable development of great potential of new generation
Biomass resource.Wherein complexing can occur with heavy metal ion rich in ester group, keto amide Ji Deng functional group, thus
Reduce the content of heavy metal in waste water.And coffee grounds has biggish specific surface area as biological adsorption agent, it also can be with dyestuff point
Son effect, reduces the concentration of dye molecule in dyeing waste water.If directly that coffee grounds investment water body cost recovery is excessively high, if not
Recycling coffee grounds can degenerate in water body, cause secondary pollution.Above-mentioned contradiction can be by by the method solution of adsorbent material immobilization
Certainly.
What matrix resin selection had good mechanical strength and a biocompatibility can be used for the poly- of fused glass pellet (FDM)
Object is closed, coffee grounds is combined with high molecular material, is produced by newest fused glass pellet (FDM) mode containing coffee grounds
