Description
Technical field
The present invention relates to sewage treatment area, more particularly to electrocatalytic oxidation equipment.
Background technology
Electro-catalytic oxidation technology is a kind of great application prospect for the poisonous Recalcitrant chemicals of processing that latest developments are got up
" green technology ".
1st, principle：
Hydroxyl radical free radical is directly or indirectly produced by the electrode reaction for having catalytic activity at normal temperatures and pressures, so that difficult
Biodegradable organic matter is converted into biodegradable organic matter, or difficult degradation organic matter change into carbon dioxide and
Water.
Key reaction：
（1）H2O2Generation:
O2+ e-→ •O2 -
•O2 -+ H+→ HO2•Or O2 -+ HO2•→O2+ HO2 -
2 HO2• →H2O2+ O2 Or HO2 -+ H+→ H2O2
（2）OH generation:
H2O2+ e-→ OH-+ OH
（3）The comprehensive function of above procedure, organic matter, ammonia nitrogen and total nitrogen in degradation water.
2nd, main structure：
Electrocatalysis oxidation reaction device is basically an electrolytic cell, mainly by shell of reactor and two pieces of pole plate structures
Into, now because the research to three-diemsnional electrode constantly promotes, it is found that three-diemsnional electrode treatment effeciency is well more many than two-dimensional electrode, therefore this
Company uses three-diemsnional electrode electrocatalysis oxidation reaction device.
3rd, the problem of prior art is present：
Mainly have at 2 points in terms of big：
（1）Can not fundamentally solve the problems such as current efficiency is low, by mass transfer and limit.
（2）Need to do further Improvement on electrocatalysis material, electrocatalysis oxidation reaction device.
First, mainly selection graphite is used as electricity to the electrocatalysis oxidation reaction device in most of practical applications on electrode material
Pole, our company were also originally the graphite electrode used.Advantage is that cost is low, corrosion-resistant, but graphite electrode intensity difference, in electric current
Density compared with it is high when export license it is big, electrocatalytic oxidation organic matter ability, current efficiency is low.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides it is a kind of it is simple in construction, water distribution is uniform, current efficiency is high, processing
The electrocatalysis oxidation reaction device that amount is big, energy consumption is low.
To realize the object of the invention, there is provided following technical scheme：On electrocatalysis oxidation reaction device, including housing, housing
The water inlet pipe at end, the water-distributing device on nearly top in housing, the packing layer being arranged in housing, setting are connected in water inlet pipe
Electrode in housing filler interval side wall, housing bottom are provided with outlet pipe, and the nearly bottom of housing is provided with aerator, and it is special
Sign is that water-distributing device lower section is provided with one layer of filter cotton, and filter cotton, which is fixed, is covered in the plastic frame of lattice-shaped first, the first modeling
Packing layer top is provided with the second plastic frame below material frame frame, and steady water layer, packing layer are formed between first and second plastic frame

Preferably, being provided with demarcation strip below aerator, permeable hole, demarcation strip and shell bottom structure are evenly equipped with demarcation strip
Into water-supplying chamber, outlet pipe is opened in water-supplying chamber's side wall.
Preferably, aerator includes aeration tube and the aeration plate being arranged on aeration tube, specific aeration plate height
Formula is：
H=-5.9073m2+6.3079h2-10.0927mh+37.9073m-10.6308h+11.8924
H-aeration plate height；
M-aeration area；
H-aeration height.
Existing frequently-used main flow aerator mainly has ceramic aerator, tube aerator and plate-type aerator.Good pottery
Porcelain aerator mass-transfer efficiency is pretty good, but cost is too high, and with the extension of usage time, their hole meeting fouling, cleaning
Need separately to take time and cost；Tube aerator cost is low, and in the absence of aeration dead band, but loss in head is big；And disc type is aerated
Device loss in head is small compared with tubular type, although aeration dead band be present, can overcome.
It has been investigated that the support height of regulation aeration tray bottom, can occur the distance of aeration plate and reactor bottom
Change, so as to which aeration plate bottom sewage agitation degree is also changing, therefore can determine that the distance of aeration plate and reactor bottom surface, make
The sewage of aeration plate region below also can be sufficiently mixed and be aerated, so as to overcome area below aeration plate in traditional reactor
The shortcomings that domain sedimentation.
Preferably, aeration quantity is set as 2.5m3/m2During h, reactor aeration area is 0.25 m2, aeration height be
During 0.5m, now optimum distance of the aeration plate away from housing bottom surface is 16cm.
Preferably, electrocatalysis oxidation reaction device electrode is plating ruthenium titanium electrode.Cost is not high, intensity is big, and catalytic activity
Height, good conductivity, corrosion resistance are strong.
Beneficial effect of the present invention：In the present invention, on electrocatalysis oxidation reaction device top, water inlet is supporting is provided with water inlet pipe
One layer of filter cotton under pipe network and pipe network, solve the problems, such as that conventional electrocatalysis oxidation reaction device water distribution is uneven；Reaction zone
The setting of interior plastic frame up and down, solve catalyst in conventional 3 D electrode reactor and flowed in aeration due to rolling acutely
The problem of mistake；Battery lead plate is changed into plating ruthenium titanium electrode by original graphite electrode, and plating ruthenium titanium electrode cost is not high, intensity is big,
And catalytic activity height, good conductivity, corrosion resistance are strong, solve original graphite electrode intensity difference, electrocatalytic oxidation organic matter energy
The shortcomings of power difference；Aeration plate sets level altitude, and aeration plate bottom sewage can be made also to obtain mixing and aeration, solve tradition
In reactor the shortcomings that the sedimentation of aeration plate region below；The setting of water-supplying chamber, traditional reactor is overcome directly from aeration
Area's water outlet, water outlet is caused to contain a large amount of gas-liquid mixtures, so as to need to be set up gas-liquid separator in addition on drainpipe the shortcomings that, effect
Fruit is good and economical and practical.
