Use principle of the present invention:
Multi-dimensional electro-catalytic reactor drum principle of work
During the work of multi-dimensional electro-catalytic reactor drum; The waste water that pumps into gets into water distributor 5 water distribution uniformities by water inlet pipe 6; Waste water is risen by slot electrode 3 bottoms and contacts mixing with the active electrode that is connected with the frequency modulation on pulse direct supply 7 with active filler particle 8, and a series of electrocatalysis chemical actions take place:
1, the electrocatalysis on active electrode:
A, organic direct electrocatalysis transform:
The electrocatalysis electrochemical action of organism on active electrode mainly is electrochemical conversion and electrode surface oxidation.Electro-chemical conversion is to be converted into non-toxic substance to the organism toxic substance, is converted into small molecules to the macromole of organism material, helps further biological treatment; The anode surface oxidation is to be the organism deep oxidation CO 2, promptly at first anode surface adsorbs radical and MOX on the anode is oxidized to high oxide:
MO x(.OH)+H 2O→MO x?(.OH)+?H ++e
MO x?(.OH)?→MO x +1+?H ++e
And then organism in the oxidized waste water:
R+MO x?(.OH)?→CO 2+MO x+?H ++e
R+MO x +1→MO x+RO
B, organic indirect electrocatalysis transform:
The electrocatalysis conversion is exactly .OH, the .O that utilizes electrochemical action on anode, to produce indirectly 2.HO 2Come oxidation and destroy organic pollutant Deng radical, up to being oxidized to CO 2And H 2O.
At the electrocatalysis in the active filler: the active filler particle that is filled with katalysis between active electrode; The active filler particle is generally by ferrous material, and inertia charcoal particle and catalyzer etc. are the material composition more than three kinds: ferrous material is iron plane flower or carbon steel wood shavings or cast iron filing composition; The inertia carbon granule is graphite or gac or coke composition; Catalyzer is that REE, binary metal or transition metal oxide are formed, and particle diameter is generally 1-5mm.Ferrous material in the active filler particle and activated carbon granule because low iron and the high charcoal of redox potential of redox potential produces potential difference in waste water, form countless galvanic cells, produce electrode reaction:
Anode (Fe): Fe---2e → Fe 2+
E 0(Fe 2+/Fe)=-0.44v
Negative electrode (C):
Under the acidic conditions: 2H ++ 2e → H 2
E 0(H +/?H 2)=0.00v
When oxygen: O 2+ 4H ++ 4e → 2H 2O, E 0(O 2)=1.23V
O 2+2H 2O+4e→4OH -, E 0(O 2/OH -)=0.40V
Through pollutent in the little electrolysis and degradation waste water of galvanic cell, comprise electrophoretic action, the reductive action of iron and Fe like this 2+, Fe 3+The complexing throwing out, the redoxomorphism of hydrogen can be decoloured to waste water, can destroy and decompose the larger molecular organics structure, can be to metal, non-metal contaminants redox, deposition, thereby reach the purpose of organic pollutant in the degrading waste water; Simultaneously, the active filler particle is under the high-gradient electric field effect, and there is dissimilar polarity generation redox reaction respectively in the small-particle two ends, and each small-particle all is a micro cell; Each short grained orientation is different, has formed multidimension electrode with the reactive electro electrode; Because the negative electrode and the anode close of each micro cell, big with the waste water contact area, the easy electricity of mass transfer is led soon; And have the catalyzer of forming by REE, binary metal or transition metal oxide in the active filler particle, can produce and the same electrocatalysis of active electrode, so current efficiency significantly improves, the treatment effect increasing, the processing costs reduction is a lot.
The present invention has applied widely, and speed of response is fast, and current efficiency is high; Treatment effect is good, and investment cost is few, and running cost is low; Long service life; Convenient operating maintenance, long-time running is effectively stable, is specially adapted to the treatment of Organic Wastewater such as dyestuff, printing and dyeing, agricultural chemicals, pharmacy, plating, process hides, mechanical application, heavy metal and garbage leachate of high salinity, high chroma, high density, high acidity, high toxicity, bio-refractory.
