摘　　要：In order to improve 4-CP degradation efficiency, a novel gas-liquid hybrid discharge （liD） reactor was developed. Removal of 4-CP with spark-spark discharge （SSD） was higher than that with spark-corona discharge （SCD）. Amount of H2O2 and O3 produced with SSD were larger than that with SCD. OH formation was increased by the combination of H2O2 and O3. The contribution of ·OH （38 % formed by O3 conversion） oxidation on removal of 4-CP accounted for nearly 60 %. The other effects of ultraviolet radiation, intense shock waves and pyrolysis, played partial roles in about 40 % of removal rate.In order to improve 4-CP degradation efficiency, a novel gas-liquid hybrid discharge （liD） reactor was developed.
