Description
Technical field
The invention belongs to a kind of processing methods of degradation of organic waste water, and in particular to a kind of original position mix sulphur activated carbon and activated
The method of sulfate degradation of organic waste water.
Background technology
In recent years, hydroxyl radical free radical high-level oxidation technology is because having the characteristics that oxidisability is strong, selectivity is low, degradation efficiency is high
It is widely used in organic wastewater with difficult degradation thereby processing.Since it has the advantages that easy to operate, oxidisability is strong, Fenotn
(H2O2/Fe2+) reagent oxidation technology becomes the high-level oxidation technology that is most widely used.But there are applicable pH ranges for the technology
Narrow, H2O2(oxidant) is unstable, is also easy to produce the problems such as sludge.And stability is high, the persulfate of good water solubility has and H2O2
Similar O-O keys, activated can generate redox potential (2.5-3.1V) is higher, sulfate radical that pH use scopes are wider from
By base, to efficiently remove persistent organic pollutants.Therefore, the advanced oxygen of persulfate in recent years based on potentiometric titrations
Change technology, it is increasingly extensive in the application of field of wastewater.
Persulfate includes peroxy-monosulfate and peroxydisulfate, it can pass through thermal activation method, photoactivation method and transition
Metal ion activation method (Critical Reviews in Environmental Science and Technology, 45:
1756-1800,2015) potentiometric titrations of strong oxidizing property are generated, but there are high energy consumption, operating condition are severe for these methods
Quarter, system complex, secondary pollution problems limit the application of persulfate high-level oxidation technology in the treatment of waste water.
If activating persulfate using a kind of nonmetallic heterogeneous catalysis, above disadvantage can be obtained by gram
Clothes.And activated carbon is since it has the advantages that large specific surface area, pore structure are flourishing, thermal stability is high, production cost is low etc., non-
Homogeneous catalysis is used widely in field.In order to widen its use scope, numerous scholars pass through surface doping hetero atom, regulation and control
The means such as pore structure carbon material surface is modified with improve its physicochemical characteristics and catalytic activity (RSC Adv.,
2014, 4, 63110–63117；Applied Catalysis B: Environmental 106 (2011) 390– 397).
Although surface doping hetero atom activated carbon has the advantages that catalytic capability is strong, activity is high, this method of modifying is formed miscellaneous
Atom functional group is not to be uniformly embedded into carbon skeleton, and be incorporated in its surface, therefore will appear in use molten
It goes wrong, or even pore structure distortion, duct can be made to block, and then surface area is caused to reduce, activity reduces.If direct carbonization contains
There is heteroatomic presoma organic matter, then above disadvantage can be obtained by and overcome.
In order to solve the above problem, the present invention propose using it is in situ mix sulphur activated carbon activation persulfate and handle difficult to degrade have
The new method of machine waste water.
Currently, invention there is no to be related to the application in situ for mixing sulphur activated carbon activation persulfate degradation of organic waste water.
Invention content：
To solve problems of the prior art, the object of the present invention is to provide a kind of organic pollutant removal efficiency
The method of sulphur activated carbon activation persulfate degradation of organic waste water is mixed in height, the original position of non-secondary pollution.

A certain amount of 2-thenyl alcohol is dissolved by solvent of acetonitrile, is slowly added to dissolved with a certain amount of FeCl3Acetonitrile it is molten
In liquid, 15h is quickly stirred at normal temperatures, being filtered, washed polythiophene sediment to filtrate for several times with distilled water and acetone successively is
Colourless, by it, the drying at 105 DEG C, obtains dry polythiophene.Polythiophene obtained and KOH according to 1:2 mass ratio into
Row mixing, by it under nitrogen atmosphere 600-800 DEG C carbonization 1h.It is inorganic to remove residual to wash carbonized samples with 10% HCl
Object, then be washed with distilled water be in neutrality for several times to supernatant after it dry under conditions of 110 DEG C is mixed into sulphur to get in situ for 24 hours
Activated carbon.Specific preparation method is shown in document (Microporous and Mesoporous Materials 158 (2012)
318–323)。
Compared with prior art, the present invention has the advantages that：
1. mixing sulphur activated carbon in the present invention in situ in addition to containing the oxygen-containing functional groups such as carbonyl, quinonyl, also contain a large amount of thiophene
Pheno sulphur and sulfuryl functional group, these groups generate activity certainly as the high-efficiency continuous activation persulfate of lewis base active site energy
By base come oxidative degradation Organic Pollutants in Wastewater.
2. the method for the present invention compared with other catalyst, not only increases the catalytic efficiency and organic pollution of catalyst
Removal efficiency, it is thus also avoided that catalyst activity component dissolves out the secondary pollution problem brought.
