The hydrolysis of series complexity, polymerization, generate flocculability material, the pollutant in water carried out adsorption-flocculation,
Thus reach to remove the purpose of pollutant.Aluminum and ferrum are to apply most anode materials at present.Pole plate is placed in
In pending water, after passing to unidirectional current, anode loses electronics, forms metal cation Al3+And Fe2+,
Being hydrolyzed to polymeric aluminum or iron hydroxide at once, the hydroxide of these polymerizations is efficient flocculant, and it is inhaled
Attached very competent, utilize its adsorption bridging and net to catch the volume effect of sweeping etc., can be by the contaminants removal in waste water.
In electricity flocculation process, water can be electrolysed.The hydrogen of the nascent state produced on negative electrode, its reducing power is very strong,
Hydrogen can be generated, or reduction reaction can be played with the pollutant in waste water.It is likely to oxygen on anode release.
Hydrogen and oxygen occur with the form of microbubble, and these bubbles can attract coagulated particles, will be wadded a quilt with cotton by buoyancy
Solidifying pollutant gas rises to the surface, thus improves water treatment efficiency.Additionally, under the effect of electric current, waste water

At present, the more commonly used electric flocculation plant is by DC source, electrolysis bath, anode, negative electrode, stirring
Device and external circuits composition.But these devices come with some shortcomings, show following some: (1) fill
Put mass transfer and diffuser efficiency is the highest, the metal cation that the magnetic stirring apparatus used can not will produce effectively
Being diffused in solution of order, thus reduce treatment effeciency；(2) volume processing sewage is little, in energy consumption
Under conditions of identical, conventional flat plate reaction unit the most treatable sewage small volume；(3) energy consumption is relatively
Greatly, the cation that pole plate produces can not be diffused in solution generation flocculability material timely, needs bigger
Electric current density and longer electrolysis time can be only achieved preferable removal effect, thus required energy consumption is the most relatively
Greatly.
