Description
Technical field
The utility model relates to a kind of water treating equipment, relates in particular to a kind of little treatment device of electrolysis wastewater.
Background technology
Iron-carbon micro-electrolysis is more and more widely the pretreated method of organic wastewater with difficult degradation thereby that is applied to.Its ultimate principle is iron filings and carbon granule to be immersed in the acid waste water, because the difference in Electrode Potential between iron and the carbon can form numerous little galvanic cell in the waste water.These trickle batteries are to become anode with the low iron of current potential, and the carbon that current potential is high is negative electrode, and electrochemical reaction takes place in containing the aqueous solution of acidic electrolyte bath.The result of reaction is that iron is subjected to corroding the iron ion that becomes divalence and enters solution.Because iron ion has coagulation, there is a natural attraction between the sexes with the particulate of faint negative charge in it and the pollutent, forms more stable throw out (iron mud) and remove.By the iron-carbon micro-electrolysis reaction, can significantly improve the biodegradability of refractory organic in the waste water, for further biochemical treatment creates favorable conditions.Its reaction process is as follows:
Anode (Fe): Fe-2e → Fe
2+
Negative electrode (C): 2H
++ 2e → 2[H] → H
2
In the reaction, generation the Fe of status nascendi
2+And atom [H], they have high chemically reactive, can change many organic structures and characteristic in the waste water, make effects such as organism generation chain rupture, open loop.If aeration arranged, i.e. oxygenation and prevent that iron filings from hardening.Also following reaction can take place:
O
2+4H
++4e→2H
2O
O
2+2H
2O+4e→4OH
-
2Fe
2++O
2+4H
+→2H
2O+Fe
3+
The OH that generates in the reaction is the reason that water outlet pH value raises, and by Fe
2+The Fe that oxidation generates
3+Hydrolysis generates the big Fe (OH) of the polymerization degree gradually
3The colloid flocculation agent can adsorb, condense the pollutent in the water effectively, thereby strengthens the pretreating effect to waste water.The iron-carbon micro-electrolysis principal feature is:
(1) speed of reaction is fast, and commonly industrial wastewater only needs half an hour to a few hours;
(2) effect organic pollution materials scope is wide, as organonitrogen, contains the hardly degraded organic substance matter of even fluorine, the two keys of carbon, nitro, halogeno-group structure, significantly improves wastewater biodegradability, reduces the toxicity to biochemical system;
(3) running cost extremely low (with other chemistry, electrochemical method ratio) only needs to consume a spot of fe (the most desirable, the most inexpensive is metal processing scrap iron particle);
(4) long service life, easy to maintenance, as long as regular interpolation iron filings, noble electrode need not be changed;
(5) has good coagulation effect, COD clearance height;
(6) can reach the effect of chemical precipitation dephosphorization, can also be by the reduction removing heavy metals;
But passivation easily takes place, hardens in traditional little electrolysis tower iron-carbon behind 2-3 lunar system, reduces effect and ineffective gradually.Because the hardening of packing layer, air can not the uniform distribution phenomenon also greatly reduces the efficient of iron-carbon micro-electrolysis, hardens simultaneously and has increased resistance also for the transmission of gas, has reduced aeration efficient.
Simultaneously, because packing layer is the iron carbon mixture of higher density, at the bottom of the porosity, adopt traditional aeration mode to tend to cause bubble slowly in the packing layer motion, can't disperse the phenomenon that rises, cause finally that gas compiles, bubble adds great achievement stream, promptly hindered contacting of filler and waste water, the while has also been reduced oxygen transfer efficiency.
