Description
Technical field
The utility model is related to sewage treatment area, more particularly to a kind of backflow for high concentration hard-degraded organic waste water
Formula iron-carbon micro-electrolysis-coupling Fenton treatment reaction devices.
Background technology
Under the historical background that Industries place extensive develops, high concentration hard-degraded organic waste water pollution sources increasingly increase, and bring
Serious pollution problem.So-called " high concentration ", refers to that the organic concentration (in terms of COD) of this kind of waste water is higher, generally exists
More than 2000mg/L, even as high as every liter had is tens of thousands of to ten tens of thousands of mg/L；So-called " difficult degradation " refers to giving birth to for this kind of waste water
The property changed relatively low (BOD5/COD values are even lower generally below 0.3), it is difficult to biodegradable." high concentration ", " difficult degradation " two
The superposition of big characteristic, and the use of conventional processing method is difficult to reach with obvious carcinogenic, teratogenesis, mutagenesis " three cause " effect
To expected treatment effect.
From after French scientist H J Fenton in 1894 have found Fenton reagent in a scientific research, with people
Fenton reactions are continued to optimize, it is most with application that Fenton methods have become in hardly degraded organic substance processing procedure research
A kind of advanced oxidation processes, compared with other advanced oxidation processes, because standby the advantages of it is simple, quick, oxidation scope is wide
Favored by people.
Standard Fenton methods refer to Fe2+/H2O2System, wherein Fe2+Mainly as the catalyst of reaction, make H2O2Pass through
The OH (hydroxy radical) that reaction is produced plays oxidation.People employ the chemical equation of a wide reference
To describe the chemical reaction occurred in Fenton reagent:Fe2++H2O2→Fe3++OH-+·OH.React the OH produced oxidation electricity
Electrode potential is up to 2.80V, and can trigger ambient substance chain reaction again, produces other more free radicals, final most of
Organic matter is degraded even mineralising, so Fenton reactions can be without most of organic matters in selective oxidation water, in the short time
It is interior to decompose oxidation operation.Simultaneously as ferrous ion can be converted into iron ion during the course of the reaction, and iron ion has
Coagulating sedimentation is acted on, and so when handling sewage, Fenton reagent can reach the effect of oxidation stain thing and coagulating sedimentation, can be with
Save follow-up coagulating sedimentation process, reduce equipment investment.
Traditional Fenton methods with Special Equipment due to accurately adding Fe2+, there is Fe in solution2+In mixed process, future is gone back
Obtain and and H2O2Reaction is just oxidized to Fe3+, cause mineralization of organic material degree is not high, dioxygen water consumption is big, operating cost is high etc.
Shortcoming.By itself and iron-carbon micro-electrolysis technical tie-up, light electrolysis-coupling Fenton oxidation method is formed, in the treatment of waste water, with suitable
With object range is wide, more preferable treatment effect and the advantages of cheap operating cost.Iron carbon forms countless small galvanic cells in waste water
Generation electrochemical reaction, while degradation of organic substances is played, iron generates countless Fe as anodic solution2+, it is follow-up Fenton
Reaction provides source of iron.Other activated carbon is a kind of common adsorbent, can the effectively colourity of Adsorption waste water, stink and water
Middle most organic pollutants.Active carbon adsorption is coupled with Fenton oxidation method, can make the strong adsorptivity of activated carbon with
The strong oxidizing property of Fenton reagent is organically combined：Activated carbon can adsorb Pollutants in Wastewater simultaneously and be reacted with Fenton reagent
Thing, makes Fenton oxidation reaction occur in activated carbon surface, so that the concentration of the neighbouring pollutants of OH (light base free radical) is improved,
Enhance the efficiency of Fenton reactions；Light base free radical meeting oxidation-adsorption solves work in the pollutant of activated carbon surface simultaneously
The problem of property charcoal regenerates.

Some caused problems, for the difficult degradation in waste water is polycyclic, heterocycle type organic and poisonous and harmful substance processing extremely has
Effect, but multistage iron carbon mix is closely connected in reactor, easily causes filler hardened so that internal waste water change of flow state increase
Reload difficulty, so as to limit its extensive use；Chinese patent 201520130858.X discloses a kind of iron-carbon micro-electrolysis-class Fenton
Experimental provision, this device mainly for Laboratory Waste Water Treatment, to a certain extent for follow-up commercial Application provide test parameters,
Theoretical foundation and technological guidance, but there is the problems such as water quality characteristic can not be controlled accurately in charging inequality, device；Chinese patent
201410585310.4 disclose a kind of electrolysis coupling class Fenton water treatment facilities, and electrolytic iron reaction is promoted to a certain extent,
Overcome filler it is hardened the problem of, reaction efficiency height, good sewage processing effect etc., but complicated, operational management is relatively numerous
Trivial, operating cost accordingly increases, and is unfavorable for practical application popularization.
