Abstract

See full text

An efficient combined advanced treatment method of electroplating wastewater is disclosed, which belongs to the technical field of electroplating wastewater treatment. The method includes: after pretreatments including cyanide breaking, dechromization and coagulating sedimentation, introducing the electroplating wastewater to a contact oxidation tank for biochemical treatment, and settling the effluent from the contact oxidation tank down in an inclined pipe of a secondary sedimentation tank to realize the separation of the sludge from water; charging the effluent to a coagulating sedimentation tank, and undergoing coagulating sedimentation with the aid of a flocculant and a coagulant aid added; feeding the effluent, as an influent, to a resin adsorption tank for adsorption with a magnetic resin; and after passing through a filter, flowing the effluent after adsorption to a fixed bed resin adsorption unit, so as to realize the discharge up to standard and recycle of the effluent.
