The theoretical principle of electric flocculation:
1. electrochemical reaction: Fe → Fe2++2e
2. anodic oxidation reactions: 2OH-→2[O]+2e→02+ 2e, nascent oxygen [O] have UV, H2O2、O3Equivalent Strong oxdiative function
Energy.
3. cathode restores: 2H++2e→2[H]→H2, nascent hydrogen can break key, COD, chromophore functional group and multichain
It is strong.
Above-mentioned oxidation and restoring function constantly occur in electrode plate.
The cell reaction formula of electric floating:
1. positive plate
2Cl → Cl2+2e- (anode surface)
Cl2+H20 → HOCl+HCl (aqueous solution)
2. negative plate
2H2O → 2H++20- 2Na++2e- → Na2 (cathode plane)
2H++2e → H2 ↑ (cathode plane) Na2+2H2O → 2Na++2OH-+H2 ↑ (in aqueous solution)
2H2O+2e→H2↑+2OH 2Na++2H2O+2e-→2Na++2OH-+H2↑(
3. continuous
Cl2+20H-→OCl-+Cl-+H2O
Present invention process utilizes electrochemical principle, acts on by applying high voltage and generates electrochemical reaction, electric energy is converted
Oxidation and reduction reaction are carried out to the organic or inorganic polluter in waste water, in turn in specific reactive tank for chemical energy
Cohesion is floated and is removed, and pollutant is separated from water body, the Cr in waste water can be effectively removed6+、Zn2+、Ni2+、Cu2+、Cd2+Deng
Heavy metal, the various noxious pollutants such as CN, grease, phosphate and COD, SS and coloration.Electric floating carries out electrolysis vapour to sewage
Bubble processing, sewage generate a large amount of ultra micro bubble hydrogen and oxygen bubbles on insoluble cathode, anode, and hydrogen bulb diameter is generally 10
~30 microns, oxygen bulb diameter is about in 20~60 microns of (steam bubble dias 100~150 that traditional pressurized dissolved air flotation generates
Micron, the steam bubble dia that when mechanical stirring generates are 800~1000 microns), bubble hydrogen and oxygen bubbles play the work of air bearing auxiliary agent
With.
Meanwhile the redox characteristic that also there are electric floating other air-float technologies not have, have both degradation of organic substances, complexing
Contact break, oxidation, reduction, decoloration and bactericidal effect, COD removal rate is higher, can be difficult to the dispersed oil small molecule to float aggregation
Become larger floating, oil emulsion demulsification be precipitated and float, so having special efficacy to oily waste water oil removing, oil removing is more thorough.To waste water
Load variations are adaptable, have generation sludge few, and equipment is simple, convenient for management, saving Water l oad variation is adaptable, have
Generate that sludge is few, equipment is simple, convenient for management, the characteristics of economizing on resources, working well.
Waste water can remove grease suspended matter and a part of COD after electric flocculation, electric floating processing, and electric flocculation produces water
Into coagulation system, coagulation system produces water and enters electric floating, and electric floating enters Rinsing Area after producing water, can remove after electric floating precipitating
Subsequent biological treatment biochemical can be improved because water pollutant bond is breakdown in color group, heavy metal, degradation COD.
The advantages of electric floating:
1, very small steam bubble is electrochemically generated, daf efficiency is high.
2. easy to operate.
3. steam bubble is tiny, surface loading is big, oil removing and high-efficient except small suspended matter.
The bubble diameter of electrofloatation generally in 10um or so, and the diameter of normal pressures air-dissolving air-float generally 100~
150um。
The radius of specific surface and bubble is inversely proportional, therefore the specific surface of electrofloatation is 2.5-10 times bigger than pressure air-dissolving air-float,
So flotation efficiency is high, corresponding oil removing and higher to the efficiency of small suspended matter.
4. shortening the mixed reaction time of coagulant.
For flotation agent usually using aluminium polychloride, incorporation time is 1~2 minute, and the reaction time is 15~20 minutes, and electric
Solution air bearing engineer testing shows the agitaion due to microbubble, and the coalescence that wadding body usually can be completed at 5 minutes is grown up and quilt
Bubble is trapped, and hydraulic detention time is shorter.Therefore air-float technology is obtained compared with other techniques under same hydraulic detention time
The effect of higher oil removing and oil removal.
5. the moisture content of dross is low, yield is few.
Unpowered equipment, has saved power consumption.It is easy to maintenance, it is provided to practical engineering application preferable controllable
