Zusammenfassung:The invention discloses a method for degrading organic pollutants by persulfate and ultrasonic stirring, which comprises the following steps: S1, adjusting the pH value of wastewater containing organic pollutants to 3.00-10.60 and then adding persulfate, or adjusting the pH value of wastewater containing organic pollutants to 3.00-7.70 and then adding persulfate and metal ions, the metal ions being one or more of Fe < 3 + >, Cu < 2 + >, Al < 3 + >, Ag < + >, Ni < 2 + >, Mg < 2 + >, Ca < 2 + > and Co < 2 + >; and S2, putting the wastewater obtained in the step S1 into an ultrasonic device, carrying out ultrasonic treatment at the ultrasonic temperature of 25-55 DEG C while starting stirring, and carrying out ultrasonic stirring treatment for 5-120 minutes to finish degradation of organic pollutants in the wastewater. Under ultrasonic and mechanical stirring, under the synergistic effect with persulfate, the effect of greatly enhancing the degradation efficiency is achieved, the degradation technology can be en
