Electrochemistry or chemistry redox occur on two electrodes or in solution for object, decompose or be converted to some innocuous substances；It can also be with
Organic matter is isolated from waste water by some physics chemical actions (such as flocculation, coprecipitated, bubble floating) in electrolytic cell
It goes to make its purification.Electrochemical process processing waste water is generally not necessarily to many chemical agents, and post-processing is simple, referred to as cleaning treatment method.
It is the decomposing H using electrode under electric field action that electrolytic method, which handles its mechanism,2O, which is generated, has Strong oxdiative ability
Hydroxyl radical free radical (OH group), so that many organic matters for being difficult to degrade be made to be decomposed into CO2Or other simple compounds.
Electrochemical reaction mechanism is the H first in solution2O discharges on anode and is formed the hydroxyl free radical of ADSORPTION STATE:
Formula (1) MOx+H2O--MOX(·OH)+H++e.(MOX is oxidizing electrode).Then show on ADSORPTION STATE hydroxyl free radical and anode
The oxygen reaction deposited, and the oxygen in hydroxyl free radical is transferred to metal oxide lattice and forms high-valence state oxide: formula (2)
MOX(·OH)--MOx+H++e。
If reaction is carried out by following formula: formula (3) MOx (OH) -- MOx+ without the organic matter of any oxidation
l/202+}r+e；Formula (4) MOx-oMOx+i/202.If there are oxidable organic matter in solution, following formula are pressed in reaction
It carries out: formula (5) R+MOx (OH): a CO2+2H+2+Mono-+MOx of e (R is organic pollutant)；Formula (6) R+M0x+1-, RO+
MOx。
As can be seen from the above equation, two kinds of active oxygens are different the oxidation effectiveness of organic matter, and the reaction of formula (5) is efficient
It when progress, shows as non-biochemical degradation organic matter deep oxidation and decomposes, i.e., ADSORPTION STATE OH major oxidation product is CO and H2O。
It is quickly carried out to make to react formula (4) (5), anode surface there must be the ADSORPTION STATE OH of high concentration, and current efficiency mainly takes
Certainly in the speed ratio of reaction formula (5) and (3)；When formula (2) and formula (6) efficiently carry out, showing as non-biochemical degradation has
Machine object is converted into bio-degradable organic matter, i.e. the oxidation product of oxygen in high-valence state oxide lattice is mainly some organic
The organic matters such as acid, quinone.To carry out formula (6) quickly, the oxygen vacancy concentration in metal oxide lattice must be sufficiently high, makes sun
The ADSORPTION STATE OH that pole generates is quickly transferred in metal oxide lattice, i.e., the speed of reaction formula (2) is than formula (1)
Fastly, current efficiency depends primarily on the reaction rate ratio of formula (6) formula (4)；The current efficiency of above two reaction with electricity
Pole material is related, and formula (4) (5) is also related with anode potential.Therefore, selecting suitable electrode material is electrolytic oxidation technical office
Manage the key problem in technology of organic wastewater.In order to improve the efficiency of OH group oxidation of organic compounds, it is necessary to prevent side reaction formula (3) and
Formula (4) limits the precipitation of oxygen, it is therefore necessary to control reaction condition, such as reaction temperature, the electricity of solution Ph value and reaction
Current density selects the electrode of high potential that can inhibit the precipitation of oxygen well.
