Description
Technical field
The utility model belongs to technical field of sewage, and in particular to a kind of Fenton iron mud regeneration device, also
It is related to a kind of Fenton methods sewage disposal system.
Background technology
Fenton oxidation method is a kind of effective advanced oxidation processes, because its equipment is simple, oxidability is strong, processing effect
Rate is high, is widely used in handling various indegradable industrial effluents.The mechanism of Fenton oxidation is Fe2+And H2O2Form Fenton
Reagent, the hydroxyl radical free radical OH that oxidizing potential is up to 2.8V is produced in acid condition, major part is organic in energy oxidized waste water
Pollutant, after reaction terminates, add alkali and neutralize, utilize caused Fe (OH)3And adsorbed with colloid, flocculation, further
Remove Organic substance in water.Although above-mentioned synergy can ensure that effluent quality is up to standard, however, the wastewater processing technology scheme meeting
A large amount of iron containing sludges are produced, secondary pollution is also easy to produce if dealing with improperly, and it is most to handle iron containing sludge caused by industrial wastewater
Hazardous waste is identified as, cost of disposal is higher, therefore becomes the burden of enterprise operation.
Iron cement method of disposal domestic conventional at present is filled after dehydrating, burning disposal and recycling treatment
(such as brickmaking) etc..Wherein landfill disposal can take a large amount of soils and waste a large amount of ferro elements, and poisonous in sludge has
Evil material can further contaminated soil, underground water etc., or even cause serious environmental pollution.Burning disposal cost is higher, burns
If caused gas control is improper during, is equally also easy to produce secondary pollution.It is existing on the method for Fenton iron mud resource
It is main to include iron cement resource is turned into ferrous sulfate product and iron cement resource is turned into two kinds of ways of Fenton catalyst in technology
Footpath.For example, Publication No. CN103252340B, CN105016589A and CN105836987A three Chinese patents disclose respectively
Three kinds of methods that iron cement resource is turned to errous sulfate crystal, however, because Pollutants in Wastewater species is different, taken in iron cement
The organic matter or heavy metal species of band are different, cause the quality of caused ferrous sulfate product after recycling cannot be guaranteed, because
This, the final use of product can not be clear and definite；In addition, copperas solution crystallization is needed to consume largely for errous sulfate crystal
The energy.In addition, during brickmaking, if sludge contains heavy metal or persistent pollutant, further processing and purification are needed.

Influence, so such a iron cement reuse method is larger to the adverse effect of Fenton water treatment efficiencies.Wherein, CN105621740A profits
Iron cement is heated to 180~200 DEG C by the method reduced with heatable catalytic, and obtained solidliquid mixture is used for as catalyst
Fenton reacts, it is well known that solidliquid mixture catalyst may influence the contact effect of Fenton reagent, so as to be unfavorable for
Fenton water treatment efficiencies.Wherein, the Fe after CN105668759A is dissolved iron cement using ultraviolet catalytic3+It is reduced to Fe2+,
And be back in Fenton reactions, it uses the organic matter after the dissolving of charcoal absorption iron cement, still, is produced after charcoal absorption
Activated carbon solid waste also need further to handle, do not realize the thorough removal of organic matter.Wherein, similarly,
CN105776783A also using ultraviolet catalytic iron cement is dissolved after Fe3+It is reduced to Fe2+, successfully it is back to Fenton reactions
In, however, the technical scheme does not refer to the processing of organic matter after iron cement dissolving, therefore, easily cause in regenerated catalyst
Organic matter enters in Fenton water treatment systems, so as to be unfavorable for Fenton water treatment efficiencies.
As can be seen here, in sewage treatment industry, need badly and develop a kind of Fenton suitable for indegradable industrial effluent
Sewage-treatment plant, operation process mild condition is feasible, can realize the reuse on the spot of Fenton iron mud, reduce iron cement
Discharge, so as to effectively reduce the dosage of Fenton process catalysts, at the same time, additionally it is possible to which thoroughly remove has in Fenton iron mud
Machine thing, finally reduce and avoid secondary pollution caused by iron cement.
