Description
Technical field
The utility model provides a kind of Fenton oxidation device.
Background technology
Fenton oxidation is an effective oxidation water treatment technology, and the technique has in sewage treatment area widely should
With.Its cardinal principle is that in acid condition, by the use of ferrous iron as catalyst, what is produced when being interacted with hydrogen peroxide is strong
Oxidisability hydroxyl aoxidizes the organic matter in water.Fenton oxidation has flexible, reaction condition quick, efficient, simple to operate gentle
The features such as.In sewage advanced treatment field, mainly for the treatment of bio-chemical effluent, hardly degraded organic substance remaining in water removal is removed, because
This, Fenton oxidation realizes one of qualified discharge or reuse important method as waste water.
In traditional Fenton oxidation, ferrous iron is to be present in the way of solution in reaction system, although oxidation processes efficiency
It is higher, but exist due to ferrous dosage is excessive chemical sludge yield is big caused by the problem of, and then cause processing
Cost increase.Meanwhile, traditional Fenton oxidation uses mechanical agitation, and mass-transfer efficiency is low, and due to reacting in acid condition
It is lower to carry out, the corrosion of equipment is easily caused, and there is the risk of increase maintenance of equipment expense.
Fenton oxidation passes through the application of many decades, and technique is greatly improved in itself.In recent years, fluidized using Fenton
Bed process.The technology makes the ferric iron produced in course of reaction largely stay in fluidisation carrier surface by fluidized crystallization technology
And continue to participate in catalytic oxidation.The technology fully combines homogeneous oxidizing, Heterogeneous oxidation, fluid bed crystallization and iron oxidation
The functions such as thing dissolving and reducing, not only ensure that treatment effect, and significantly reduce the dosage of ferrous iron, and reduce iron cement
Yield.But the technology generally uses the less particle of particle diameter（Such as quartz sand, queen closer, aluminum oxide micro-sphere, grit）As
Catalyst carrier, particle diameter is most of between 0.5-1.0mm, forms preferable fluidized state if desired, generally requires larger
The current rate of climb（General more than 30m/h）, it is therefore desirable to larger power is consumed, so as to add the running cost of system
With.Also, with the long-play of system, the iron cement of generation is constantly wrapped in carrier particle surface so that diameter of carrier
Constantly increase, maintains normal fluidized state, then must increase power or the carrier more renewed if desired.Meanwhile, in order to anti-
Only the race stream of catalyst is lost, and solid-liquid separator, such as inclined plate sedimentation device, perforated baffle need to be typically set above fluidization regions
Deng adds somewhat to equipment investment.
Therefore, it is necessary to design Fenton oxidation device a kind of not only cost-effective but also that efficient process can be realized.
