    Abstract: A method and an apparatus for treating plating wastewater are provided to treat efficiently the plating wastewater at a low cost, by treating ammoniac nitrogen, organic nitrogen, and nitrate after treating chrome, heavy metal, cyan, etc., contained in the plating wastewater. A chrome in wastewater is reduced, and a heavy metal is removed from the wastewater through cohesion and pressure flotation(S10). The treated wastewater is inputted into an electrolyte unit to remove cyanogen, ammoniac nitrogen, and organic nitrogen, and a reducing agent is inputted into the treated wastewater to remove remaining chlorine(S20). The treated wastewater is inputted into a bioreactor to remove nitrate from the wastewater(S30).
