Description

A kind of can the continuous wastewater treatment equipment of the online little electrolysis of regenerated iron charcoal
Technical field
The utility model relates to the little electrolysis wastewater water treatment device of iron charcoal, particularly a kind of can the little electrolysis organic waste water of online regenerated iron charcoal apparatus for continous treatment.
Background technology
Iron charcoal micro-electrolysis method is to utilize Principles of Metal Erosion, the technology of handling through the microcell waste water that forms iron and carbon.This method uses waste iron filing to be raw material, and " treatment of wastes with processes of wastes against one another ", with low cost, and also use range is wide, treatment effect is good, long service life.Since mining company's invention iron charcoal micro-electrolysis treatment waste water technology is ruled together by Japan, there have been many inventors to utilize this principle in the world, developed various wastewater treatment equipments through original creation design, improvement flow process etc.Yet; Existing iron carbon micro electrolyser all various defect can occur in use for some time, and the most outstanding is: 1, stopping composition (iron filings and gac) lumps, occurs channeling easily; Or whole little electrolysis zone stops up, the waste water difficulty is passed through, and reduces processing efficiency greatly; Though 2 have the design fluidized-bed can solve obstruction, caking phenomenon, this method will keep that power consumption is big, stopping composition runs off easily; 3, iron charcoal micro-electrolysis method mainly is little electrolytic oxidation to the handling principle of organic waste water, and its principle is:
(1) because the electromotive force of iron and carbon has notable difference, iron filings that in electrolyte solution, are in contact with one another and carbon constitute numerous small galvanic cells, and iron is corroded as anode, and carbon is as negative electrode; Fe constantly loses electronics and becomes Fe 2+Get into solution, the electron transport that loses is to the surface of carbon, H in solution +When concentration is higher, H +Surperficial electron gain at carbon reacts; Under oxygen atmosphere, O 2At carbon surface electron gain generation chemical reaction.Electrode reaction is following:
1., anode (Fe): Fe-2e → Fe 2+
2., negative electrode (C): 2H ++ 2e → 2 [H] → H 2
When aerobic: negative electrode: O 2+ H 2O+4e → 4OH
Fenton reaction: O also can take place under the sour environment 2+ 2H ++ 2e=H 2O 2
Fe 2+?+?H 2O 2?=?Fe(OH) 2+?+?OH*
Contain N, S, O, P, the equiatomic organism of As, N, S, O, P, last not one-tenth key lone-pair electron ability and the Fe of As 2+On outer unoccupied orbital form co-ordination bond; Form baroque macromolecule complex, reduced water-solublely, make these organism have certain colloid property, can be able to deposition through the adsorption bridging effect and remove.
But organism is except at Fe 2+On absorption need the time short outside, those difficulties are attracted to Fe 2+On organism have only by oxidation removal, oxidising process needs the long period, must be adsorbed on the gac earlier, and then generated acid by the OH* free-radical oxidn, last and Fe 2+Or Fe 3+Generate sedimentable matter, and obtain handling.The problem that two aspects might occur like this:
If 1 waste strength is very high, after charcoal absorption was saturated, system had little time all to decompose adsorbed organism, and organism unnecessary in the waste water certainly will directly pass through device, got rid of from the exit, so just can't reach the purpose of processing!
Can't be if contain in 2 waste water by the organism of the little electrolytic waste water treatment equipment degraded of this iron charcoal, this organism also can only along with gac constantly adsorbs, finally be reached capacity by charcoal absorption.Continue to handle, then unnecessary organism also can directly pass through device, gets rid of from the exit.
With regard to above-mentioned situation, we adopt the way of changing stopping composition (gac+iron filings) usually, and this has following three aspect shortcomings:
1, the waste material of whole device must all be changed, and waste material is changed difficulty, wastes time and energy.
2, the waste material that changes because contain iron filings, toxic organic compound, organism molysite, is seen off and please Activated Carbon Production producer be regenerated, and has both damaged the other side's equipment easily, also can cause environmental pollution to the other side again, and therefore general producer all is reluctant to accept.
