The invention discloses a kind of more metal surfaces to crystallize concerted catalysis oxidation reactor, including a catalyst oxidation reactor, setting three phase separator, fluidized crystallization area, circulation water distributing area in reactor.The present invention is the improving technology of conventional oxidation method, uses manganese, magnesium, iron, aluminium alloy for catalyst, and the synergistic effect of various metals is catalyzed H2O2Oxidation reaction.The dosage of ferrous ion can be greatly reduced.The pH range that reaction needs is expanded simultaneously, is reduced operating cost, is reduced sludge yield.
Description
Technical field
The present invention relates to a kind of more metal surfaces to crystallize concerted catalysis oxidation reactor.
Background technique
High-level oxidation technology of the Fenton oxidation method as a kind of sewage treatment, by OH free radical to having in waste water
Machine object carries out deep oxidation, it is considered to be a kind of most effective, simple advanced oxidization method, with high efficiency, rapid reaction
Advantage is generally used for processing organic wastewater with difficult degradation thereby.Traditional Fenton oxidation method have medicament in need is more, operating cost compared with
The disadvantages of height, the big sludge quantity generated, improvement has been carried out in the technology of traditional Fenton at present, electrolytic oxidation occurs
Fenton method, electroreduction Fenton method, photocatalysis Fenton method etc..The degradation of common Fenton method mainly includes to having
The oxidation of machine object and two kinds of coagulation effects.Fe is referred to the oxidation of organic matter2+With H2O2Effect, generating has extremely strong oxidation
The hydroxyl radical free radical OH of ability and the radical reaction carried out；On the other hand, the Fe (OH) generated in reaction3Colloid has wadding
Solidifying, adsorption function also can remove water part organic matter.But there are two disadvantages for it: first is that needing to add a large amount of outer additional examination
Agent increases operation cost；Second is that generating a large amount of iron cement amount, it is separated by solid-liquid separation difficult to which subsequent needs are put at large-scale sludge
Science and engineering skill.
Summary of the invention
In view of the above drawbacks of the prior art, the technical problem to be solved by the present invention is to develop a kind of reduction dosage
And more metal surfaces of sludge yield crystallize concerted catalysis oxidation reactor.
To achieve the above object, the present invention provides a kind of more metal surface crystallization concerted catalysis oxidation reactors 4, including three
Phase separator 1, fluidized bed, crystalline carrier, circulation water distributing area.Sewage enters in reaction tower, and manganese, magnesium, iron, aluminium alloy are arranged in tower
The synergistic effect of catalyst 2, various metals is catalyzed H2O2Oxidation reaction.FeSO can be greatly reduced4Dosage, reduce
Operating cost；Iron containing sludge yield is also reduced therewith.Simultaneously because the presence of manganese, reaction pH be can be improved to 4~6.By more
Metal surface crystallizes concerted catalysis oxidation reactor, can reduce 50% ferrous sulfate dosage and 70% sludge yield.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of crystallization concerted catalysis oxidation reactor in more metal surfaces of the invention.
Fig. 2 is the result figure for the treatment of nature water experiment of the invention.

Specific embodiment
Experimental method
1. elevator pump lifting test waste water 200L is used, until raw water slot；
2. adjusting above-mentioned wastewater pH to 4 using 40% technical grade sulfuric acid；
3. adding multimetal reforming catalyst 1kg or so in concerted catalysis oxidation reactor, start circulating pump, adjusts flow
200L/h。
4. starting raw water pump, flow of inlet water 700ml/min is adjusted, starts continuum micromeehanics；
5. starting dosing pump, 30%H is added in catalyst oxidation reactor2O2Medicament, catalytic oxidation start；
6. from flowing to effluent trough, catalyst flows in reactor for upper layer water outlet after catalyst oxidation reactor processing, not with
Water outflow；
7. after 2~3 hours on-tests, collecting processing water water sample.Then, using batch test method, while stirring plus
30%NaOH adjusts pH to 7 or so, stirs 10min.Then, 2hr is staticly settled, supernatant is taken to be discharged, Analysis for CO D.Analysis knot
Fruit see the table below.
Experimental facilities is shown in Table 1.
Table 1: testing equipment list
Interpretation of result
This has carried out experimental analysis to raw water water inlet and bio-chemical effluent respectively, as a result as follows:
1) treating nature water is tested
Under the conditions of adding the multimetal reforming catalyst of equivalent, this tests the discussion for having carried out 4 kinds of dosing conditions altogether, COD:
H2O2: FeSO4=1:2:2, COD:H2O2: FeSO4=1:1:1, COD:H2O2: FeSO4=1:0.5:0.5, COD:H2O2: FeSO4
=1:0.25:0.25, as a result as shown in Fig. 2 (a) (b):
Pressing raw water COD:H2O2: FeSO4When the ratio of=1:2:2 adds medicament, treatment effect is best, and COD removal rate can
Up to 75%, raw water COD:H is being pressed2O2: FeSO4When the ratio of=1:0.25:0.25 adds medicament, COD removal rate up to 47%,
Removal effect is good
2) advanced treating experiment is carried out to bio-chemical effluent
Under conditions of adding equivalent multimetal reforming catalyst, this tests the discussion for having carried out 3 kinds of dosing conditions altogether, respectively
For COD:H2O2: FeSO4=1:0.5:0.5, COD:H2O2: FeSO4=1:0.25:0.25, COD:H2O2: FeSO4=1:0.15:
0.25, as a result such as Fig. 3 (a) (b):
It is bio-chemical effluent COD:H in medicament adding proportion2O2: FeSO4When=1:0.5:0.5, removal rate 72.4%,
COD:H2O2: FeSO4When=1:0.25:0.25, removal rate 44.3%, treatment effect is good.
According to more than experimental result analyzing, increase as dosage increases removal efficiency, general sewage uses catalysis oxidation
Reactor dosage is in COD:H2O2: FeSO4=1:1:1 can reach preferable removal effect, and traditional Fenton oxidation method is thrown
Dose is generally raw water COD:H2O2: FeSO4=1:2:4 (rule of thumb and operation result obtains, this time without control experiment), because
This is according to this experimental result, FeSO4Dosage can at least reduce 50%.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
