Description
Technical field
The present invention relates to a kind of wastewater treatment method and systems, and in particular to a kind of processing high toxicity high concentrated organic wastewater
Method and system.
Background technique
At this stage, the organic wastewater that printing and dyeing enterprise is discharged, usual complicated component are in addition to containing with aniline, benzidine
Outside a variety of organic matters of aromatic series containing N of main matter, also contain highly toxic cyanogen root (CN-), cyanate radical (OCN-), thiocyanate radical
(SCN-) etc. inorganic compound containing N, the usual > 10000 of the value of COD it is even higher.Currently, the processing for this kind of waste water, main
If by the method for various advanced oxidations, by various macromolecular organic matter containing N (long-chain molecule or the aromatics in waste water
Object) and it is inorganic containing cyanogen compound, it is converted into the N of small molecule organic matter containing N or inorganic states as far as possible2And CO2.However, this kind of
The all more or less Shortcomings of method and defect.Therefore, in practice, need to be improved and combined, convenient for actual
High concentrated organic wastewater carries out depth degradation.
Currently, the processing for this kind of printing and dyeing organic wastewater, used advanced oxidation processes specifically include that
(1) chlorine oxidation process.This method is mainly passed through chlorine (Cl into waste water2), pass through the hypochlorite of generation
(ClO-), by the organic and inorganic pollution of waste water, by way of degrading and restoring, it is changed into hypotoxicity, it is tractable
Substance.This method is preferable to the treatment effect of low concentration wastewater, but for the waste water of high concentration, then treatment effect is bad, and
It is easy to produce that toxicity is bigger, handles more difficult cyanogen chloride (CNCl) and dioxin-like chemical.
(2) photochemical oxidation method.This method mainly utilizes strong oxidizing property hydroxyl radical free radical caused by ultraviolet excitation,
It is degraded or is restored to pollutant.This method equipment it is easy to operate, but in the presence of no catalyst, removal
Limited efficacy, and energy consumption is high.And catalyst is used, although efficiency can be significantly improved, cost can significantly rise.
(3) electrochemical oxidation process.This method is similar with photochemical oxidation method, is to utilize hydroxyl free caused by electrolysis
Base is degraded to pollutant or is restored.This method equipment it is easy to operate, and removal efficiency is also higher than photochemical oxidation method.
But since it needs to consume more electric energy, and positive and negative anodes electrode material needs long-term replacement, therefore cost can be higher.
Summary of the invention
A kind of processing high toxicity high concentration is provided it is an object of the invention to overcome the shortcomings of the prior art place
The method and system of organic wastewater.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of processing high toxicity high concentrated organic wastewater
Method, comprising the following steps:
(1), CuSO is added in high toxicity high concentrated organic wastewater4And Na2SO3, remove sediment；
(2), step (1) treated organic wastewater is subjected to level-one ozone Oxidation Treatment；
(3), step (2) treated organic wastewater is subjected to secondary ozone oxidation processes, while FeSO is added4And alkali,
Remove sediment；
(4), step (3) treated organic wastewater is subjected to biological denitrificaion processing, the organic wastewater that obtains that treated.
Due to, in addition to containing a large amount of aromatic compound (mainly aniline and benzidine), also containing a certain amount of in raw water
CN-、OCN-And SCN-, oxidability are as follows: OCN-> CN-> SCN-.Wherein, SCN-It is big to aoxidize difficulty, and is easy to produce toxicity
Greatly, the difficult secondary pollution of processing, but its concentration is relatively small.Therefore, CuSO is selected before being aoxidized4And Na2SO3It is logical
The method for crossing precipitating thoroughly removes it.The removing of sediment can be by filtering or standing removing, CuSO4And Na2SO3It can
Think that solid may be solution.The reaction occurred are as follows:
2SCN-+2Cu2++SO3 2-+H2O=2CuSCN ↓+2H++SO4 2-
Step (1) treated organic wastewater carries out ozone Oxidation Treatment, and the reaction occurred is as follows:
3CN-+O3=3OCN-
2OCN-+O3=CO2+CO3 2-+N2
2OCN-+3O3+H2O=2HCO3 -+N2+3O2
C6H5-NH2+3O3→R-NO3
H2N-(C6H4)2-NH2+3O3→R-NO3
It is mainly CO by contained substance in step (2) treated organic wastewater3 2-、HCO3 -、SO3 2-, small molecule nitrogen
Close object, and the CN not being completely removed-And OCN-(the remaining Cu of dosing in step (1)2+By CO3 2-And HCO3 -Double hydrolysis are gone
Except).In order to be completely removed, excessive FeSO is added in the water outlet after ozone treatment by the present invention4, by double hydrolysises,
Remove the CO generated3 2-And HCO3 -；By generating (Prussian blue) precipitating of barba hispanica, CN is removed-, it is not open close enter ozone exposed
Gas, and suitable alkali is added, by remaining Fe2+And SO3 2-, and the excessive Fe generated3+, removed by way of precipitating.
The reaction that the process is occurred is as follows:
4Fe2++4CO3 2-+O2+6H2O=4Fe (OH)3↓+4CO2↑
4Fe2++8HCO3 -+O2+2H2O=4Fe (OH)3↓+8CO2↑
Fe2++6CN-=Fe (CN)6 4-, Fe (CN)6 4-+2Fe2+=Fe2[Fe(CN)6]↓
6Fe2++3SO3 2-+4O3+3H2O=2Fe (OH)3↓+4Fe3++3SO4 2-+3O2
Fe3++3OH-=Fe (OH)3↓
After secondary ozone oxidation processes and agent-feeding treatment, most pollutants has been removed, however, there are also not
When young molecule itrogenous organic substance is not completely removed.Therefore, in order to organic N is converted to N2, by treated, waste water is carried out
Biological denitrificaion processing, by the nitration and opposite nitration of microorganism, is converted to N for organic N2, reach the mesh of advanced treating
