Method for catalytic treatment of organic pollutants in wastewater by using copper tailings

The invention discloses a method for catalytic treatment of organic pollutants in wastewater by using copper tailings. The method comprises the following steps: washing the copper tailings with water, and drying at 50-70 DEG C; adding a hydroxylamine hydrochloride solution into wastewater containing organic pollutants, uniformly mixing, then adding the copper tailings obtained in the step 1, and fully stirring and mixing to obtain a suspension; adding a potassium persulfate solution into the suspension to start degradation reaction; the copper tailings are low in cost and easy to obtain, the catalyst with high catalytic activity can be obtained through simple water washing, and a new thought of utilizing the tailings is provided; the hydroxylamine is coupled with the copper tailings, so that the efficiency of catalyzing the persulfate to degrade the organic pollutants in the water by the copper tailings is enhanced, and the method has a wide application prospect in the aspect of treating the organic pollutant
