Description
Technical field
The utility model is related to a kind of technical field of sewage.Specifically, the utility model is related to a kind of for deep
The Fenton's reaction device of the high-leveled and difficult organic wastewater of degree treatment.
Background technology
1894, Frenchman HJHFenton had found that using Fe2+/H2O2 systems gas chromatography can be aoxidized.Afterwards
In honor of the combination of ferrous salt and hydrogen peroxide is referred to as Fenton reagents to people by him, and it can the efficient oxidation removal conventional waste water
The hardly degraded organic substance that treatment technology cannot be removed, generates with height its essence is H2O2 under the catalytic action of Fe2+
The hydroxyl radical free radical (OH) of reactivity, OH can make it degrade with the effect of most of organic matters.With going deep into for research
, and ultraviolet light (UV), oxalates (C2O42-) etc. are introduced into Fenton reagents, greatly enhance its oxidability.From
Inventionbroadly, Fenton methods are, using catalyst or light radiation or electrochemical action, hydroxyl free to be produced by H2O2
Base (OH) processes the technology of organic matter.H2O2 decomposes generation OH, its oxidizing potential under the catalytic action of Fe2+
2.8V is reached, is most strong inorganic oxidizer in addition to element fluorine, it is divided oxidation operation by approach such as electro transfers
Solution is into small molecule.Meanwhile, Fe2+ is oxidized to Fe3+ and produces coagulating sedimentation, removes large amount of organic.It can be seen that Fenton
Reagent has two kinds of effects of oxidation and coagulation in water process.Fenton reagents in the dark just can degradation of organic substances, saving
Equipment investment, has the disadvantage that the utilization rate of H2O2 is not high, can not abundant mineralising organic matter.Research shows, using Fe3
+, the heterogeneous catalysis such as homogeneous catalyst and iron powder, graphite, iron, the oxide mineral of manganese such as Mn2+ H2O2 can equally decomposed
OH is produced, the referred to as Fenton-like system because it reacts that basic process is similar with Fenton reagents.Such as use Fe3+
Instead of Fe2+, because Fe2+ is to produce immediately, the chance that OH is reduced by Fe2+ is reduced, can improved
The utilization ratio of OH.If adding some complexing agents (such as C2O42-, EDTA) in Fenton systems, can increase
To the clearance of organic matter.The reaction of Fenton reagent oxidation organic matters, is to generate hydroxyl in hydrogen peroxide with iron ion action
Free radical, and trigger more free radicals, attack organic molecule internal key reaches organic matter is completely inorganization or is cracked into small
The purpose of molecule.But the Fenton equipment treatment effect in actual items is poor, and variation water quality difference is also very big, it is impossible to very stable
Guarantee water outlet effect.
The content of the invention
The utility model is in view of the shortcomings of the prior art, there is provided a kind of efficient, convenient, economical and practical Fenton treatment dress
Put
The utility model is to solve above-mentioned technical problem, there is provided following technical scheme：It is new that a kind of Fenton oxidation is processed
Type device, including cylinder（1）, positioned at cylinder（1）The water inlet of bottom（2）, circulation water inlet（3）、H2O2Dosing mouth（6）, sulfuric acid
Ferrous dosing mouth（7）And positioned at the delivery port on cylinder top（4）, it is characterised in that cylinder（1）It has been additionally arranged at the bottom of circulation water inlet
Mouthful（3）, cylinder（1）Top has additional circulating outlet（5）, circulation water inlet（3）With circulating outlet（5）By circulating line
（8）Connection, circulating line（8）On be provided with circulating pump（9）.A circulating pump is increased in the utility model, using water sample
Circulate to reach the effect of balanced water quality and quantity, reduce the agitating device in original equipment, and than original device
More efficiently, make effluent quality more balanced, water treatment efficiency is higher.
The utility model beneficial effect：Device is mainly used in the organic matter that Fenton oxidation treatment can be removed effectively in water body.
Whole system stable operation, efficient, convenient, floor space is small, economical and green.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Embodiment 1：A kind of new device of Fenton oxidation treatment, including cylinder（1）, positioned at cylinder（1）The water inlet of bottom
Mouthful（2）, circulation water inlet（3）、H2O2Dosing mouth（6）, ferrous sulfate dosing mouth（7）And positioned at the delivery port on cylinder top
（4）, cylinder（1）It has been additionally arranged at the bottom of circulation water inlet（3）, cylinder（1）Top has additional circulating outlet（5）, circulation water inlet
（3）With circulating outlet（5）By circulating line（8）Connection, circulating line（8）On be provided with circulating pump（9）.
Zhejiang Medicine Factory, main waste water is pharmaceutical intermediate wastewater, and variation water quality is big, and organic concentration is high, biochemical
Property is poor, and specific data are as follows：
Claims (1)
1. a kind of new device of Fenton oxidation treatment, including cylinder（1）, positioned at cylinder（1）The water inlet of bottom（2）, circulation
