Change and removes.Effect including following several respects: (1) flocculation: the anodes such as soluble anode such as iron, aluminium pass to direct current
After electricity, after anode loses electronics, metal cation Fe2+, Al3+ are formed, generates metal hydroxides glue with the OH- in solution
Body flocculant, this kind of hydrogen in statu nascendi oxide active is high, adsorption capacity is strong, with colloid, suspended matter, the soluble contaminant in raw water
Object, bacterium, virus etc., which combine, generates larger flock, is removed through precipitating, air bearing.(2) air bearing act on: in electrolytic process when
When voltage reaches the decomposition voltage of water, hydrogen and oxygen is precipitated respectively on cathode and anode, the gas of generation is with dispersion degree pole
The form of high micro-bubble occurs, be adhered to each other with pollutants such as colloid, emulsus oil in raw water shift to the water surface and by
Removal.The bubble that electric flocculation generates is much smaller than the bubble that pressure floatation air generates, thus its air bearing ability is stronger, goes to pollutant
Except effect is also more preferable.(3) oxidation: the oxidation in electrolytic process divides direct oxidation and indirect oxidation.Direct oxidation, i.e.,
Pollutant directly loses electronics in anode and aoxidizes.Indirect oxidation, using the lower anion of electrode potential in solution,
Such as OH-, Cl- lose the active material [ O ] for being electronically generated new stronger oxidant, Cl2 etc. in anode, utilize these activity
Substance makes pollutant lose electronics, oxygenolysis is played, to reduce BOD5, CODcr in stoste, ammonia nitrogen etc..(4) it restores
Effect: reduction point direct-reduction and indirect reduction in electrolytic process.Direct-reduction, i.e. pollutant obtain directly on cathode
Reduction occurs to electronics.Indirect reduction, i.e., the sun in pollutant are electric in so that electrolyte from obtaining in first in cathode
Middle high price or low-valent metal sun are from being directly reduced to cation or precipitated metal at a low price in obtaining electronics on cathode.
