Description
Technical field
The invention belongs to waste disposal plant, a kind of specifically electrocatalysis oxidation apparatus of the recoil that refluxes.
Background technology
Sewage from bottom to top or from top to bottom steadily passes through plate regions in the electrocatalysis process, has certain space between the positive/negative plate, more or less there is certain dead angle in whole catalyzed oxidation zone, and the branch that has power in the time of must causing sewage through electric field influences processing efficiency.Under electric field action, be present in electrode surface or the solution " small amount of matter " (can be electroactive or non-electroactive) and because character of electrode materials own or condition of surface characteristic, can significantly quicken the electron-transfer reaction that on electrode, takes place, and " small amount of matter " or electrode itself do not change, and this phenomenon is referred to as electrocatalysis.
With the titanium plate as anode, graphite is as under the condition of negative electrode and under the energy excitation that provides of external electric field, by a large amount of O that aeration in the groove is provided
2Capture the electronics that external electric field provides, form oxyradical ion O
2-, the oxyradical ion induces H
2O
2Generate hydroxyl radical free radical ion OH at last.Hydroxyl radical free radical ion OH has high oxidisability, most organic molecule chain can be interrupted generally speaking, produces hydrolysis and acidifying effect, and a part of organism is directly by mineralising, and makes BOD
5/ COD ratio promotes, and follow-up conventional materialization and biochemistry can carry out, for good prerequisite, environment are created in final processing up to standard.
The problem that waste water exists is handled in general electrocatalysis:
1, polarization phenomena.Because the ion diffusion motion can not be finished immediately during electrolysis, different with the ionic concn of solution inside near the ionic concn in the electrode surface solution thin layer, the result produces a kind of concentration polarization, and its potential difference is also opposite with the impressed voltage direction.
2, corrosion phenomenon.Because the existence of concentration polarization makes positive plate be subject to H+ accumulation erosion, negative plate is subject to OH and corrodes in electrolytic process.Thereby reduced current efficiency.
At present, multiple chemical engineering sewage all exists " heterocycle " molecular chain and cannot or hardly open, interrupt, and causes in the sewage disposal that numerous materials do not have biochemical or a biochemical extreme difference, and the sewage after causing handling can not qualified discharge.
In highly difficult chemical engineering sewage treatment process, (its key structure is as negative electrode and anodic pole plate to have begun to quote catalytic oxidation equipment in the market, pole plate contacts with water when work, " heterocycle " in the water of decomposition), but because catalytic oxidation equipment is a kind of height piezoelectricity, physics, chemistry, machinery, hydromeehanics one very complex apparatus that integrates, main drawback has:
1, energy consumption is big, and applying unit all calls electric-tiger to the catalytic oxidation device.
2, the disposable effect of sewage disposal is undesirable, gets reflow treatment repeatedly, and the Ruo Dingliu time extends, and is subjected to critical limitations (then the device fabrication cost is big) to handling the water yield.
3, the pole plate working loss is big, and the replacement cycle is short, causes cost of investment big.
4, the accumulation of pole plate soil pick-up increases behind the equipment work, and it is serious to deteriorate, admittedly influence equipment life, efficient or precipitation dirt repeated treatments.
