The invention relates to the field of wastewater treatment, in particular to a method for treating high-concentration phosphating wastewater, and the method comprises the following steps: (1) adding coagulant PAC (polyaluminium chloride) and magnetic powder into the phosphating wastewater, stirring and mixing to obtain a first-level mixing system; (2) adding coagulant aid PAM (polyacrylamide) intothe first-level mixing system, stirring and mixing to obtain a secondary mixing system; (3) adopting an air floatation machine to carry out air floatation separation on the secondary mixing system toobtain effluent and scum, and by combining magnetic coagulation and air floatation technology, the method not only reduces the usage amount of medicaments, but also reduces the treatment time and occupied area, and improves the treatment efficiency.
