In processing high COD, the waste water of bio-refractory.
Ozone oxidation is very capable, O3+2H++2e→O2+H2The standard electrolytic current potential of O reaction system reaches 2.07V, ozone
Decomposing generation elemental oxygen in water and oxygen can also produce a series of free radical, these newly-generated hydroxyl radical free radicals are the most alive
Sprinkling, oxidability is higher, therefore has extremely strong oxidisability, can be aoxidized by the Organic substance in waste water etc., thus the COD that degrades.
Electrochemicial oxidation used water difficult to degradate is that pollutant occur Direct Electrochemistry reaction on electrode or continue to employ electrode
Surface produce strong oxidizing property active substance make pollutant generation oxidoreduction change, by anodic oxidation make organic pollution with
Part inorganic pollution is converted into innocuous substance；Electrochemical oxidation can effectively process organic wastewater with difficult degradation thereby, and with other skill
Art is compatible, synergy is good.
Fenton oxidation at present, ozone oxidation, advanced electrochemical oxidation process have obtained universal in terms of waste water process
Application, but some shortcomings are individually present, there is certain limitation, limit the actual application that waste water processes；Raw for high COD difficulty
The feature of the waste water changed, combines fenton oxidation, ozone oxidation and electrocatalytic oxidation, learns from other's strong points to offset one's weaknesses, can be efficient
Process this type of waste water.
Summary of the invention
For prior art exist the problems referred to above, the applicant provide a kind of COD degradation efficiency improving waste water and
The method of biochemical property.The inventive method uses fenton oxidation ozone oxidation electrocatalytic oxidation combination method, first passes through
Fenton method carries out primary oxidation, then by remaining ferrous ion during fenton method and iron ion catalysis ozone, produces more
Free radical, waste water is carried out secondary oxidation, under the catalytic action of chloride ion, finally carries out electrocatalytic oxidation, waste water is carried out
Three oxidations, make the organic pollution in waste water substantially decompose, and reduce COD, improve the purpose of biochemical.Use this scheme
Waste water repeatedly can be aoxidized, compensate for the limitation of single method, improve process range and ability.
