The invention belongs to the technical field of ground engineering of oil and gas fields and in particular relates to a process for removing refractory CODs (chemical oxygen demands) in produced waterof a high-sulfur-content gas field. Aiming at situations that refractory COD components in produced water of a high-sulfur-content gas field and CODs in fed water after pretreatment are generally 1000mg/L and are refractory CODs, and to achieve resource recycling of the produced water of the high-sulfur-content gas field, the invention discloses the process applicable to removal of refractory CODs in produced water of the high-sulfur-content gas field, a treatment process of "Fenton oxidation+ozone ultraviolet photocatalytic oxidation+micro/ultrafiltration membrane+reverse osmosis membrane" is adopted, and organic components such as refractory CODs and volatile phenols in the produced water of the high-sulfur-content gas field can be degraded and removed. In a situation that the CODs of produced water are less than or equal to 1000mg/L, the process is adopted for treatment, and CODs of an effluent after treatment qualification are less than or equal to 50mg/L.
