After treatment with"aeration+contact oxidation+flocculation precipitation",the remaining COD in high salt epoxy propane wastewater has become difficult to degrade.Enterprises urgently need to upgrade process to meet the discharge requirements of COD＜30 mg/L,and experiments with"ozone+contact oxidation"as the main process route have been conducted.The experimental results show that this process has the characteristics of good stability and strong impact resistance,and can stably ensure that the COD ofthe effluent is less than 30 mg/L.
