Description

technical field [0001] The invention relates to the technical field of environmental pollutant treatment, in particular to a method for degrading organic pollutants by activating persulfate with supported alumina particles. Background technique [0002] In recent years, with the rapid development of my country's economy and the advancement of global industrialization, a large number of toxic and harmful organic pollutants have entered the environmental water body in the process of production and use, causing serious water pollution. Among them, a variety of organic pollutants have low-dose effects, persistence, and bioaccumulation, and can be transmitted between populations through the food chain. They have obvious teratogenic, carcinogenic, and mutagenic effects, which seriously threaten aquatic organisms and even human health. , it can be seen that efficient and convenient water treatment technology is urgently needed in this field for pollution control.
