Description
Technical field
The invention belongs to noble metal recovery technology fields, and in particular to the method for recycling platinum charcoal.
Technical background
Platinum is one kind of platinum group metal, chemical symbol Pt, atomic number 78, atomic weight 195.08, with silvery white
Non-ferrous metal gloss, fusing point are 1772 DEG C, there is good ductility, thermal conductivity and electric conductivity.The chemical property torpescence of platinum, in sky
Highly stable in gas, when less than 450 DEG C of heating, surface forms platinum dioxide film, can be with sulphur, phosphorus, halogen under high temperature
Learn reaction.Platinum does not dissolve in hydrochloric acid, sulfuric acid, nitric acid and alkaline solution, but can be dissolved in chloroazotic acid and the alkali of melting.Platinum be in the earth's crust most
Rare one of element, compound is varied, may be used as urging for the fields such as chemical industry, pharmacy, oil refining, purifying vehicle exhaust
In agent.
Currently, the whole world has 50% platinum to be distributed in South Africa.And the platinum mineral resources wretched insufficiency of China.Therefore, secondary
Platinum is recycled in resource just seems extremely important.The platiniferous electroplate liquid and platiniferous that platiniferous waste water is primarily present in electroplating industry are urged
The waste liquid generated after agent dissolving.The characteristics of these platiniferous waste water is platinum content height, difficult to degrade.Conventional recovery method be to platinum or
Platinum carbon catalyst, useless electric slurry are roasted, and are dissolved after roasting, later separating-purifying.The disadvantage of this method maximum
It is that electric slurry and element will produce poisonous and hazardous flue gas during roasting, to the body of operator and neighbouring resident
Body causes directly to injure, and secondly, will produce NO, NO when nitric acid dissolves fired slags2Equal pernicious gases, if without processing
It is directly discharged in air that air pollution can be caused.Therefore, the method for finding a high-efficiency environment friendly recycling platinum is particularly significant.
Currently, having had been reported that the feasibility and actual effect for having studied microbial method recycling platinum.Its principle mainly passes through
Absorption of the microorganism to platinum, makes it be attached to the surface of microorganism, by the redox of microorganism, platinum ion is made to restore
For metal simple-substance.But pure bacterium bioreactor is selected in wherein most research, is unfavorable for actual popularization and application.The present invention uses
Anaerobic biological reactor realizes that the resource utilization of platinum waste water utilizes as experimental provision.Anaerobic biological reactor method is recycling
COD is reduced while platinum ion, is had a good application prospect.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind under certain conditions, is given birth to using anaerobism
The method of microorganism recycling platinum charcoal in object reactor, for handling platiniferous waste water and resource utilization using the platinum member in waste water
Element.
The object of the present invention is achieved like this:The anaerobic biological reactor that domestication is completed is placed on magnetic stirring apparatus,
The certain density platiniferous waste water of preparation is added in anaerobic biological reactor, after reacting a period of time, collects excess sludge
It is carbonized, is obtained containing platinum and carbon simple substance mixture, i.e. platinum charcoal with the biomembrane to fall off.
Description of the drawings:
Fig. 1 is the structural diagram of the present invention:
It is in figure:Platiniferous waste water 1, anaerobic reactor 2, platiniferous excess sludge 3, carbonizing apparatus 4, platinum charcoal 5, water outlet 6.
Specific implementation mode
Below in conjunction with the accompanying drawings, the present invention is further illustrated:As shown in Figure 1, a kind of micro- life of anaerobic biological reactor
The method that object recycles platinum charcoal, which is characterized in that including platiniferous waste water 1, anaerobic reactor 2, platiniferous excess sludge 3, carbonizing apparatus
4, platinum charcoal 5, water outlet 6.
Platiniferous waste water 1 is passed through in anaerobic reactor 2, reacts discharge platiniferous excess sludge 3 and water outlet 6 after a period of time,
In, platiniferous excess sludge 3 carbonizes in carbonizing apparatus 4, obtains platinum charcoal 5.

Embodiment 3:As a concentration of 8.44 mg/L of the platinum ion that platiniferous waste water is added, anaerobic reactor is placed in magnetic force
On blender, rotating speed is 200 rpm, reacts 24 h, and aqueous concentration is 0.67 mg/L, removal rate 92.06%.
Embodiment 4:As a concentration of 16.88 mg/L of the platinum ion that platiniferous waste water is added, anaerobic reactor is placed in magnetic force
On blender, rotating speed is 200 rpm, reacts 24 h, and aqueous concentration is 1.58 mg/L, removal rate 90.63%.
