%X An improved electro-Fenton technology with stainless steel anode and cathode of graphite-based gas diffusion electrode is introuced in this work to enhance removal rate of COD in semi-coke wastewater which is famous for high treatment cost as its biodegradation is hard. By several exhaustive experiments, the optimum removal rate of COD is up to 78.62% at the optimized conditions in the laboratory of the oxygen sparging rates of 2.5 L/min, the optimal electrode plates distance of 2 cm, current density of 5.2 mA/cm2, solution pH of 3, and duration of 240 min, which provides a high efficiency pretreatment for semi-coke wastewater, and an promising new method for the treatment of non-biodegradable high concetration wastewater in the future.
