Percolate, wastewater from chemical industry, pharmaceutical wastewater, high ammonia-nitrogen wastewater, high salinity waste water etc., the organic dirt of difficult for biological degradation in these waste water
Dye object is difficult to be removed by the method for microorganism, is removed by the oxidation of chemistry or electrochemistry.Electrochemistry
Reaction is considered as a kind for the treatment of technology of high effective green environmentally friendly, to generating multiple catalyzing oxidation by electrochemical reaction,
Directly refractory organic direct oxidation can be removed for carbon dioxide and water.
Electrochemical water treatment technology is to pass through a system in specific electrochemical reactor using the effect of extra electric field
Chemical reaction, electrochemical process or the physical process of row reach expected removal Pollutants in Wastewater or recycle the mesh of utility
's.Electrochemical oxidation ammonia nitrogen is exactly the process by mineralized nitrogen at nitrogen by the direct oxidation and indirect oxidation of electrode.
Electrochemical oxidation (electrochemical oxidation, electro-oxidation) method is most probable by work
One of the high-level oxidation technology of industryization application, is referred to as " environmentally-friendly technique ".Have compared with other high-level oxidation technology techniques

Or seldom generate secondary pollution；
(4) energy efficiency is high, and reaction condition is mild, generally can be carried out at normal temperatures and pressures；
(5) it both can individually handle, can also be combined with other treatment process, such as be used as pre-treatment, can improve useless
The biological degradability of water.
The research of electrochemical oxidation general mechanism
The essence of electrochemical oxidation is a kind of electrocatalytic reaction, is to make electrode and the charge transfer reaction on electrolyte interface
It is able to a kind of catalytic action accelerated.Inventionbroadly, it can cause the electrode of electrode reaction that can be known as elctro-catalyst, i.e. electro-catalysis
Electrode.Electrochemical reaction speed or the changed electrode of selectivity will be generally caused all to be called electro catalytic electrode, it is such
Reaction is called electrocatalytic reaction.Electrocatalytic reaction can occur for anodic oxidation, cathodic reduction, negative and positive the two poles of the earth synergistic effect, wherein
Anodic oxidation research is more.
(1) anodic oxidation
Anode oxidation process is to select active anode material in electrolysis reactor, and tool is generated near anode
There is the active substance of oxidation to carry out oxidative degradation pollutant.According to the difference of the mechanism of action, direct oxidation and indirect oxidation can be divided into
Two classes.During direct oxidation, pollutant is adsorbed onto electrode surface first, is then passed by the direct electron between electrode
It passs and makes its degradation；Indirect oxidation is strong oxidizer (such as hypochlorous acid, hydroxyl radical free radical and the metal oxygen generated by electrode reaction
Change reduction electricity equity) make the reaction of contaminant degradation.Direct electrochemical oxidation refers to that can make organic pollution by anodic oxidation
It is converted into innocuous substance with part inorganic pollution.It is divided into the progress of two classes：First, being electrochemically transformed, noxious material is changed into nothing
Noxious material, or the organic matter of biocompatible is converted into the substance of bio-compatible, for example, aromatic compound ring-opening oxidation etc.,
After can carry out biological subsequent processing；Second is that electrochemical combustion, can be directly CO by organic matter deep oxidation2And H2O.Indirect oxidation
Not only the effect of anode direct oxidation had been played to a certain extent, but also some groups in anodic oxidation solution can be utilized to generate strong oxygen
Agent, the pollutant in indirect oxidation waste water, therefore treatment effeciency greatly improves, and achievees the purpose that enhancing degradation.
(2) cathodic reduction
Cathodic reduction is exactly to select suitable cathode material (graphite, mesh structural porous carbon electricity under cathode potential appropriate
Pole, carbon-polytetrafluoroethylene (PTFE) cathode oxygenated cathode etc.), make O using cathodic reduction reaction2It is reduced to the H with oxidation activity2O2,
To aoxidize organic pollution.Due to H2O2Oxidizing potential be not very high, so that its oxidability is restricted, therefore in the solution
Introduce Fe2+Equal metal ion catalysts, are catalyzed H2O2HO is generated, its oxidability, i.e., so-called " electric Fenton " skill are enhanced

The ordinary electrode slot of two electrodes.Smaller for tablet two-dimensional electrode face body, unit groove body treating capacity is small, and current efficiency is low equal scarce
Point proposes the concept of three-diemsnional electrode in phase late 1960s, and has carried out using the research with mechanism.Three-diemsnional electrode is
A kind of model electrochemical reactor, electrode of also calling out-bed.It is granular or other are broken in traditional two-dimentional electrolyzer electric interpolar filling
Bits shape working electrode material simultaneously makes filling working electrode material surface charge, and becomes a new pole (third pole), in working electrode
Electrochemical reaction occurs for material surface energy.Three-diemsnional electrode can be divided into unipolarity and multipole by particle polarity；It is filled out by particulate material
The mode of filling can be divided into fixed form and the type of flow.Three-dimensional electrolysis, which is electrolysed the processing of waste water difficult for biological degradation compared with conventional two-dimensional, to be had
Have the characteristics that low energy consumption, efficient.But there is also many drawbacks, such as three during practical engineering application for three-dimensional electrolysis at present
The selection of electrode is tieed up, treatment effeciency is still relatively low, and processing cost is still higher.
