摘要：

Supercritical water oxidation (SCWO) of waste drilling fluid had been examined in a high-pressure reactor under the following conditions: reaction temperature, 510 to 570 degrees C; H2O2 dosage, 1000 to 7000 mg/l; and residence time, 1 to 7 min.. The effects of the given experimental conditions and KOH concentration on total organic carbon (TOC) removal of waste drilling fluid were investigated with laboratory bench -scale experiments. The results indicated that KOH addition improved TOC removal. The addition of 300 mg/l of KOH accelerated the oxidation of the organic pollutant in the waste drilling fluid. The optimum TOC removal reached 97.6% under the experimental conditions.
