Description
Technical field
The present invention relates to a kind of many metal surfaces crystallization concerted catalysis oxidation reactor.
Background technology
Fenton oxidation method is as the high-level oxidation technology of a kind of sewage disposal, by having in OH radical pair waste water
Machine thing carries out deep oxidation it is considered to be a kind of advanced oxidization method most effective, simple, has high efficiency, reaction quickly
Advantage, is generally used for processing organic wastewater with difficult degradation thereby.Traditional F enton oxidizing process has that medicament in need is more, operating cost relatively
The shortcomings such as sludge quantity high, that produce is big, have been carried out at present improving in the technology of traditional F enton, occur in that electrolytic oxidation
Fenton method, electroreduction Fenton method, photocatalysis Fenton method etc..The Degradation of common Fenton method mainly includes having
The oxidation of machine thing and coagulation two kinds effect.Organic Oxidation is referred to Fe2+With H2O2Effect, generates and has extremely strong oxidation
The hydroxyl radical free radical OH of ability and the radical reaction that carries out；On the other hand, the Fe (OH) generated in reaction3Colloid has wadding
Solidifying, adsorption function, it is possible to remove partial organic substances in water.But there are two shortcomings in it: one is to need to add substantial amounts of outer additional examination
Agent, adds operation cost；Two is to produce substantial amounts of iron cement amount, and solid-liquid separation is difficult thus follow-up needs puts at large-scale mud
Science and engineering skill.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is that exploitation one reduces chemical feeding quantity
And many metal surfaces crystallization concerted catalysis oxidation reactor of sludge yield.
For achieving the above object, the present invention provides a kind of many metal surfaces to crystallize concerted catalysis oxidation reactor 4, including three
Phase separator 1, fluid bed, crystalline carrier, circulation water distributing area.Sewage enters in reaction tower, arranges manganese, magnesium, ferrum, aluminium alloy in tower
Catalyst 2, the synergism catalysis H of various metals2O2Oxidation reaction.FeSO can be greatly reduced4Dosage, reduce
Operating cost；Iron containing sludge generation amount reduces the most therewith.Simultaneously because the existence of manganese, reaction pH can improve to 4～6.By many
Metal surface crystallization concerted catalysis oxidation reactor, can reduce by ferrous sulfate dosage and the sludge yield of 70% of 50%.
Below with reference to accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is described further, with
It is fully understood from the purpose of the present invention, feature and effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of many metal surfaces crystallization concerted catalysis oxidation reactor of the present invention.
Fig. 2 is the result figure of the treating nature water experiment of the present invention.
Fig. 3 is the result figure that bio-chemical effluent carries out advanced treating experiment of the present invention.
Detailed description of the invention
Experimental technique
1. elevator pump lifting test waste water 200L is used, to former tank；
2. 40% technical grade sulphuric acid is used to regulate above-mentioned wastewater pH to 4；
3. in concerted catalysis oxidation reactor, add multimetal reforming catalyst about 1kg, start circulating pump, regulate flow
200L/h。
4. start raw water pump, regulate flow of inlet water 700ml/min, start continuum micromeehanics；
5. start dosing pump, in catalyst oxidation reactor, add 30%H2O2Medicament, catalytic oxidation starts；
6. after catalyst oxidation reactor processes, upper strata water outlet is from flowing to effluent trough, and catalyst flows in reactor, not with
Water flows out；
7., after on-test 2～3 hours, collection processes water water sample.Then, use batch test method, add while stirring
30%NaOH, regulates pH to about 7, stirs 10min.Then, staticly settle 2hr, take supernatant water outlet, Analysis for CO D.Analyze knot
Fruit see table.
Experimental facilities is shown in Table 1.
Table 1: testing equipment catalog
Interpretation of result
This has carried out experimental analysis to the water inlet of former water and bio-chemical effluent respectively, and result is as follows:
1) treating nature water experiment
Under the conditions of the multimetal reforming catalyst adding equivalent, this test has carried out the discussion of 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, shown in result such as Fig. 2 (a) (b):
By former water COD:H2O2: FeSO4When the ratio of=1:2:2 adds medicament, treatment effect is best, and COD clearance can
Reach 75%, by former water COD:H2O2: FeSO4When the ratio of=1:0.25:0.25 adds medicament, COD clearance up to 47%,
Removal effect is good
2) bio-chemical effluent is carried out advanced treating experiment
Under conditions of adding equivalent multimetal reforming catalyst, this test has carried out the discussion of 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, result such as Fig. 3 (a) (b):
It is bio-chemical effluent COD:H in medicament adding proportion2O2: FeSO4During=1:0.5:0.5, clearance 72.4%,
COD:H2O2: FeSO4During=1:0.25:0.25, clearance is 44.3%, and treatment effect is good.
Analyzing according to more than experimental result, increase along with chemical feeding quantity increases removal efficiency, general sewage uses catalysis oxidation
Reactor chemical feeding quantity is at COD:H2O2: FeSO4=1:1:1 i.e. can reach preferable removal effect, and traditional F enton oxidizing process is thrown
Dose is generally former water COD:H2O2: FeSO4=1:2:4 (rule of thumb and operation result draws, this time without control experiment), because of
This is according to this experimental result, FeSO4Chemical feeding quantity at least can reduce 50%.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art without
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technology in the art
Personnel are available by logical analysis, reasoning, or a limited experiment the most on the basis of existing technology
Technical scheme, all should be in the protection domain being defined in the patent claims.
