Background technology
The characteristics of electrochemical water treatment technology is a kind of new water technology, the technology is to remove waste water using electric energy
In organic pollution.Electro-chemical water processing is carried out in a cell, in anode region organic pollution by direct or indirect oxidation,
Degraded is up to mineralising, while in cathodic region, organic pollution can be reduced modification, but can not be degraded.Due to having in waste water
Organic pollutants concentration is far below the concentration of waste water reclaimed water, so the current efficiency that anode region is used for oxidation of organic compounds is relatively low, typically
Less than 30%, the current efficiency of residue about 70% is used for occurring the electrode reactions such as analysis oxygen, analysis chlorine；Meanwhile, cathodic region is used to reduce
The current efficiency of organic matter is also than relatively low, and generally below 30%, the current efficiency of residue about 70% is used for occurring evolving hydrogen reaction.Cause
This, substantial amounts of electric current energy consumption is wasted.
Fenton's reaction is that the class based on Fenton reagent (hydrogen peroxide and ferrous ion) is reacted, and produce has by force in the reaction
The hydroxyl radical free radical (OH) of oxidisability, can be by the organic pollution oxidation in waste water, degraded until mineralising is inorganic matter.By
In hydrogen peroxide and ferrous ion in mol ratio 1:1 or so, and the consumption of hydrogen peroxide is directly proportional to the organic pollution in waste water, institute

Chinese patent 201610335240.6 passes through cathodic reduction Fe3+For Fe2+, although solve turning for Fe3+ to Fe2+
Change, but dissolving iron cement needs outer acid adding, and generation iron cement needs exogenously added alkali again.Further, since O2Saturation solubility in waste water
Relatively low (being about 10mg/L in 45mg/L, actual waste water in 20 DEG C of pure water), using O2Cathodic reduction prepares H2O2Accumulate Fenton anti-
Answer required H2O2Concentration needs that the residence time of waste water in a cell is significantly increased, and causes power consumption to be substantially increased.
