FIELD: equipment for treatment of industrial sewage water, may be used for deactivation of sewage from non-ferrous and ferrous metals.
SUBSTANCE: apparatus has casing filled with galvanic coupling and equipped with branch pipes for feeding of sewage water, discharge of treated water, feeding of galvanic coupling, and removal of sludge. Casing is formed as cylindrical column of non-magnetic material, and solenoid coils disposed on outer surface of said column. Casing bottom is connected through non-magnetic restricting grid and safety valve to device for preparing aqueous dispersion of air. Device for preparing of aqueous dispersion of air comprises air disperser, branch pipe for feeding of treated water, converging arcuate channel, plate with slit-type openings having rectangular section, and valve formed as flexible rubber plate having one side rigidly fixed by means of metal planks.
EFFECT: enhanced reliability in operation and increased efficiency in treatment of sewage water.
