Description
Technical field
The invention belongs to advanced treatment of industrial waste water technical fields, and in particular to a kind of electricity collaboration persulfate advanced treating
The method of organic matter in high-salt wastewater.
Background technique
In recent years, it is limited to current social economic development level and state-of-art, many chemical industries are inevitable
The high-concentration salt-containing wastewater that discharge largely containing organic pollutant, these pollutants ecological environment multipair greatly and human body are harmful,
And influence or even harm are caused on water resource and water environment.Since the salt content of such waste water is higher, conventional micro- life
Object is difficult to survive, grow, and traditional biodegradable mode is caused to be difficult to handle it.Coal chemical industry is the warp using coal as raw material
The technique that chemical conversion makes coal be converted into gas, liquid and solid fuel and other chemicals is crossed, is a kind of typical highly concentrated
Spend organic wastewater with difficult degradation thereby.It is carcinogenic, teratogenesis toxic that there is a large amount of ammonia nitrogen, phenols, polycyclic aromatic hydrocarbons etc. in coal chemical industrial waste water
Harmful substance has the characteristics that COD value is high, salt content is high, coloration is deep, hard-degraded substance is more, and belonging to high-concentration hardly-degradable has
Machine waste water needs effectively to be handled before being discharged into natural water.
Currently, a series of physics, chemistry, biology and its complex art are used for the treatment of coal chemical industrial waste water, including film mistake
Filter method, biological degradation method, chemical oxidization method etc..But the high salt concentration of coal chemical industrial waste water limits biodegradation process, and contain
The high phenolic compound concentration having easily leads to serious fouling membrane, and simple chemical oxidization method is in processing hardly degraded organic substance side
Face effect is poor.Therefore, a kind of cleaning is needed to, green, efficient method handle such waste water.
Advanced oxidation processes (Advanced Oxidation Process, AOP) are also known as deep oxidation, generate in the process
The organic matter that can contain in the efficient oxidation degrading waste water of the free radical (such as hydroxyl radical free radical OH) with strong oxidizing property, tool
Have the advantages that reaction speed is fast, processing is complete, applied widely, it has also become the hot spot of current water treatment technology research.Traditional
High-level oxidation technology mostly carries out the organic matter of high stability using Fenton and Fenton class reagent and ozone effective
Oxygenolysis, still, there is also larger tired in this problem of COD value in reducing the higher industrial waste sewage of salt content
Difficulty, and there are problems that secondary pollution.
The advanced oxidation processes for activating persulfate are emerging saliferous wastewater processing technologies, activate the sulfate radical generated certainly
By base oxidability near or above hydroxyl radical free radical (SO4 -Oxidation-reduction potential E0The oxidation of=2.5-3.1V, OH are also
Former current potential E0=1.89-2.72V), and SO4 -Stability be more than OH (SO that traditional advanced oxidation processes generate4 -Half-life period
For 40 μ s, the considerably longer than half-life period of OH (< 1 μ s)), keep it bigger with the haptoreaction chance of pollutant.Moreover, being based on
Sulfate high-level oxidation technology, the potentiometric titrations oxidative degradation organic matter generated using activation sodium peroxydisulfate, product are
SO4 2-, for itself containing a large amount of Na2SO4New secondary pollution is not constituted with the coal chemical industry high-salt wastewater of NaCl, is a kind of ideal
Processing method.Compared to traditional high-level oxidation technology, activation persulfate oxidation method is strong with oxidability, oxidant is steady
The advantages of fixed and pH wide adaptation range.In addition, stability under persulfate good water solubility, room temperature is high, after cheap, reaction
Product is mild.Therefore, based on the high-level oxidation technology of persulfate in wastewater treatment, especially coal chemical industrial waste water advanced treating is answered
It has a extensive future in.
To the activation of persulfate, there are many means in the prior art, typical as thermal activation, alkali activation, ultraviolet light are living
Change, transition metal activation etc..But alkali activation haves the defects that equipment corrosion；UV activation coalification higher for coloration
The treatment effect of work waste water is poor；Then there is secondary pollution and itself free radical be quenched in transition metal activation.
Electrochemical process acts on organic matter since persulfate can be made to generate more polyradical under the action of electric microfield
Oxidation removal, and directly or indirectly oxidation can be realized in electrode surface, therefore, electrochemistry cooperates with the combination of persulfate method can be
Oxidation efficiency is improved to a certain extent, and becomes the preferred technique of industrial wastewater organic matter processing.But current electrochemistry association
It is needed with persulfate technology by iron or ferrous ion as activator, by-product inevitably generates in treatment process more
Iron cement can generate certain secondary pollution.As it can be seen that traditional electricity collaboration persulfate high-level oxidation technology, due to activator
In the presence of still there is certain limitation for the advanced treating of organic matter in high-salt wastewater.
Summary of the invention
