摘要：
In this paper, supercritical water oxidation (SCWO) is applied to treat waste drilling fluid. Effect of different reaction conditions on chemical oxygen demand (COD) removal are examined. in a high-pressure reactor under the following conditions: 480 degrees C to 570 degrees C; oxidation coefficient (OC), 0.5 to 3.5; initial COD concentration, 5000 mg/L to 20000 mg/L; and residence time,5 min to 20 min. The effects of the given experimental conditions and NaOH concentration on the removal efficiency of waste drilling fluid were investigated with laboratory bench-scale experiments. The results indicated that NaOH addition improved COD removal. The optimum COD removal reached 99.93% under the experimental conditions. BOD5/COD ratio is 0.54.
