|a The aim of this article was to obtain the application parameters and conditions of in situ sodium persulfate/calcium peroxide oxidation. For the purposes of remediation, soil from a total petroleum hydrocarbons (TPH)-contaminated site was collected and prepared to reflect the actual stratum condition in a newly developed soil remediation modeling apparatus. Application methods of soil mixture, natural infiltration, direct injection and groundwater circulation were used to simulate in situ sodium persulfate oxidation in TPH-contaminated soil. Results showed that the transfer capability of Na2S2O8 in simulated soil was strong Na2S2O8 migrated to the saturated layer after 3 days of in situ injection, which then continued both horizontal and vertical migration. After 7 days the oxidant was widespread in the saturated layer with a radius of influence of 0.4 m. It was found that mixing CaO2/Fe2+/CA with soil and spraying Na2S2O8 can effectively repair the surface-contaminated soil, and the longitudinal migration of Na2S2O8 in the reaction process can further strengthen the remediation of the upper layer soil. Due to the buffering effect of the soil, the effect of oxidation on the pH and temperature of different soil layers was small, but detectable in comparison to natural environmental factors
