Description

Strengthen Fenton/class Fenton's reaction system removal water pollutant using free chlorine Method
Technical field
The present invention relates to a kind of method for treating water, and in particular to strengthens Fenton/class Fenton's reaction system using free chlorine and goes Except the method for water pollutant.
Background technique
Fenton's reaction is by ferrous ion (Fe2+) and hydrogen peroxide (H2O2) composition a kind of advanced chemical oxidation technology, The hydroxyl radical free radical (HO) of strong oxidizing property can be generated, oxidation reaction can occur with hardly degraded organic substance in aqueous solution to broken Its bad structure, therefore have a wide range of applications in multiple fields.Fenton reagent is to be sent out by French scientist Fenton in 1894 It is existing, have many advantages, such as applied widely, the small, strong antijamming capability of pollution and is swift in response.In Fenton's reaction, H2O2In Fe2 +The hydroxyl radical free radical (HO) with strong oxidizing property can be generated under catalysis, and generate Fe3+, Fe3+Can also and H2O2Reaction, it is raw At Fe2+.Entire reaction process realizes Fe2+And Fe3+Between circulation, and continuously generate living radical (HO, HOO·).HO electron affinity energy power is high, with non-selectivity can quickly aoxidize various organic compounds, be oxidized rapidly for CO2Or H2O is converted into other organic matters being readily biodegradable.Class Fenton's reaction system refers to using Fenton reagent, changes one A little conditions (such as ultraviolet lighting, electric Fenton) or the reaction for being doped with metal (copper, zinc, zirconium) other than iron etc..
Fenton's reaction, which has waste water difficult for biological degradation, toxic wastewater and Biostatic waste water, to be stablized, effectively removes Function can handle different types of waste water because it is swift in response, applied widely, degrade a variety of polysaccharide polymers the advantages that, More and more attention are at home and abroad obtained.
But there are H for individual Fenton system for handling2O2The disadvantages of consumption is big, and iron throwing amount is more, at high cost, pH narrow application range.
Summary of the invention
The purpose of the present invention is to solve existing Fenton system for handling, there are H2O2Consumption is big, and iron throwing amount is more and pollutes The poor problem of object removal effect, and provide and strengthen Fenton/class Fenton's reaction system removal water pollutant using free chlorine Method.
The present invention follows these steps to realize using the method that free chlorine strengthens Fenton's reaction system removal water pollutant:
One, the pH value of pending water is adjusted in 2.0~4.0 ranges;
Two, ferrous salt is then added into pending water, stirs pending water, and hydrogenperoxide steam generator is added;
Three, (quick) addition hypochlorite solutions or be passed through chlorine again, make the concentration 1 of effective chlorine in system~ 15mg/L carries out reinforcing reaction, to remove water pollutant.
The present invention follows these steps to realize using the method that free chlorine strengthens class Fenton's reaction system removal water pollutant:
One, the pH value of pending water is adjusted in 2.0~4.0 ranges;
Two, transition metal salt is then added into pending water, stirs pending water, and single persulfate is added or crosses two sulphur Hydrochlorate;
Three, (quick) addition hypochlorite solutions or be passed through chlorine again, make the concentration 1 of effective chlorine in system~ 15mg/L carries out reinforcing reaction, to remove water pollutant;
Wherein transition metal salt described in step 2 be one of ferrous salt, mantoquita, zinc salt, zirconates, cobalt salt, manganese salt or The a variety of mixtures of person.
Fenton or Fenton-like itself of the present invention can generate the strong free radical of oxidation, certainly such as hydroxyl By base, potentiometric titrations etc..But the stability of hydroxyl radical free radical, potentiometric titrations is poor, Css in the solution It is low.After free chlorine (hypochlorite or chlorine) is added in system, pass through free chlorine and chloride ion and hydroxyl radical free radical and sulfuric acid The reaction of root free radical generates a large amount of Cl, ClO, Cl2The high Kinds of Free Radicals of equal Css, thus improve Fenton Degradation effect of the system to pollutant.
The present invention using free chlorine strengthen Fenton's reaction system remove water pollutant method compared to individual Fenton/ Fenton-like can be improved 30%~50% to the removal rate of pollutant, subtract the dosage of hydrogen peroxide or persulfate Few 20%~50%, so that the dosage of ferrous iron or other metal salts is reduced 30%~60%, the reaction time is made to shorten 2~10 Times.
