Summary: | To provide a decomposition prediction method for removing trace contaminants in secondary wastewater by ultraviolet/sodium persulfate.SOLUTION: The method includes the following steps: (S1) use p-chloro benzoate and naproxen as reference materials and establish a kinetic model of the reaction kinetics of target contaminants, p-chlorobenzoic acid, naproxen and free radicals under ultraviolet/sodium persulfate, (S2) add target contaminants, p-chloro benzoic acid, and naproxen to an actual water sample and perform oxidative decomposition using an ultraviolet/sodium persulfate high oxidation process, and (S3) calculate a free radical content according to an effect of decomposing p-chloro benzoic acid and naproxen using a model to predict the decomposition of the target contaminants.SELECTED DRAWING: Figure 4
